•  BMW 6-Series Gran Coupe, 2013

Introducing the BMW 6-Series Gran Coupe - a new 4-door, 4+1 seat addition to the 6-Series line that successfully combines the stunning proportions, design and driving dynamics of the 6-Series Coupe with interior room and amenities for up to five passengers. Harmonious proportions, precise lines and sleekly contoured surfaces give the BMW 6-Series Gran Coupe the unique ability to satisfy the driver who wants a luxurious and sporty coupe yet needs a car capable of carrying four adults in comfort and luxury. The BMW 6-Series Gran Coupe will be offered as three distinct models in the USA. The TwinPower Turbo 6-cylinder powered 2013 BMW 640i Gran Coupe is the initial model and arrives early this summer. Later in the summer 2012, the TwinPower Turbo V-8 powered 2013 BMW 650i Gran Coupe and the all-wheel drive 2013 BMW 650i xDrive Gran Coupe will join the range.

Sporting a length of 197 inches (5,007 mm) and wheelbase of 116.8 inches (2,968 mm), the Gran Coupe is 4.4 inches (111 mm) longer than its 2-door coupe sibling. A significant part of this extra length has been used to enhance seating comfort for the rear passengers. The BMW 6-Series Gran Coupe is also 74.6 inches (1,894 mm) wide and stands 54.8 inches (1,392 mm) in height. For comparison purposes, the Gran Coupe is 4.0 inches (102mm) longer, 1.3 inches (34mm) wider and 2.8 inches (72mm) lower than the BMW 550i.

The BMW 6-Series Gran Coupe, in keeping with the tradition of the 6-Series Coupe, offers a unique combination of top-class sporting dynamics, stunning design, luxurious touring comfort and a 16.24 cu. ft (460-liter) DIN luggage compartment - now for four passengers. The BMW 6-Series Gran Coupe's signature driving experience is complimented by a range of innovative driver assistance systems and BMW ConnectedDrive infotainment features. The new car therefore meets the highest expectations of driving pleasure and style in a large, premium 4-seat sports coupe.

Its unmistakable design language gives the new BMW 6-Series Gran Coupe an aura of athletic elegance. The long powerfully contoured hood, short front overhang and set-back passenger compartment team up with a 4.4 inch (111 mm) increase in body length over the 6-Series Coupe and a 4.5 inch (113 mm) longer wheelbase present a fresh take on the hallmark proportions of a BMW automobile. The Gran Coupe's distinctive profile is dominated by its four-door, elegantly stretched roof line which flows smoothly into the rear end, is a similarly eye-catching and distinctive feature of the new model's silhouette.

The innovations in the new BMW 6-Series Gran Coupe also extend to lighting technology, in the shape of optional Adaptive LED Headlights. Their bright white light provides an extremely intense and evenly spread illumination of the road. This technology is unparalleled in the segment and also allows the beam of the headlights to follow the curves of the road.

Other features that set the new car apart from its rivals are the BMW ConnectedDrive driver assistance systems and mobility services. The rear-view camera, Surround View, Parking Assistant, BMW Night Vision with pedestrian recognition, Lane Departure Warning System and Active Blind Spot Detection are joined on the list of available equipment items by the new generation of the BMW Head-Up-Display. The latest incarnation of the system uses a full spectrum of colors to display the information projected onto the windshield. The standard BMW iDrive control system is the operating portal for the navigation, communications and infotainment functions. The high definition, trans-reflective technology Control Display is centrally mounted high on the sweeping dash and emulates a freestanding flatscreen. Finally, the optional Bang & Olufsen High-End Surround Sound System provides a feast of aural pleasure seldom experienced inside a car.

The BMW 640i Gran Coupe arrives in US BMW Centers early summer 2012 and will be followed by the 650i Gran Coupe and 650i xDrive Gran Coupe in late summer.

Upgraded TwinPower Turbo 6-Cylinder powers the 640i Gran Coupe.
The inline 6-cylinder engine (N55HP) in the new BMW 640i Gran Coupe will impress performance-minded drivers with its effortless power, exceptionally fast-revving temperament, outstanding refinement and exceptional fuel efficiency. The N55 has been setting standards from the start, as the pioneer of a new generation of engines in which BMW TwinPower Turbo technology with High Precision Direct Injection and VALVETRONIC variable valve timing plus a twin scroll turbo made its debut.

Thanks to intensive fine-tuning of the engine, BMW's engineers have managed to extract additional performance from the engine while maintaining its exceptional fuel efficiency. With a maximum power rating of 225 kW/315 hp at 5,800 to 6,000 rpm, the 3.0-liter 6-cylinder engine reflects the sporty personality of the BMW 640i Gran Coupe and helps this automobile deliver brilliant performance. The high peak torque of 330 lb-ft, on stream between 1,300 and 4,500 rpm, ensures that the power is effortlessly and instantly delivered.

As a result, the 640i Gran Coupe can show off its prowess with a 0 to 62 mph (0-100km/h) sprint time of just 5.4 seconds. Top speed is electronically governed at 155 mph (250 km/h). All this extra performance comes with exceptional fuel economy and low emission figures. Fuel consumption in the EU test cycle is rated at 7.8 l/100km (30.1 mpg). EPA fuel economy ratings will be available closer to the on-sale date in the USA.

BMW's widely lauded TwinPower Turbo V-8 engine is updated with more performance and more efficiency in the 650i Gran Coupe.

The 4.4-liter V-8 engine (N63) that powers the current 650i models receives an upgrade for the new 650i Gran Coupe. The unique "reverse-flow" engine, whose two turbochargers are positioned in the V-area between the cylinder banks is well known for producing an instantaneous and sustained wave of power, making it a delight for the enthusiast driver. This new version of the engine adds BMW's VALVETRONIC variable valve timing to the list of specifications. As a result, the new version of the engine (N63Tü) develops a maximum 445 hp between 5,500 and 6,000 rpm (a 45 hp increase), and makes peak torque of 480 lb-ft between 2,000 and 4,500 rpm (a 30 lbs-ft increase).

The new BMW 650i Gran Coupe completes the sprint from 0 to 62 mph (0 to 100km/h) in 4.6 seconds. Top speed is electronically limited to 155 mph. This engine also boasts extraordinary efficiency for a model in its output class. Its average fuel consumption lies between 8.6 and 8.8 l/100km (26.7-27.3 mpg), (provisional figures according to EU test cycle depending on tire options). EPA fuel economy ratings will be available closer to the on-sale date in summer 2012.

When the V8 is combined with the xDrive intelligent all-wheel-drive system, its power is converted into even more intense and dynamic acceleration. The electronically controlled power split between the front and rear wheels optimizes not only traction and stability, whatever the weather and road surface conditions may be, but also the agility of the Gran Coupe 650i xDrive Gran Coupe, whose sprint time from 0 to 100 km/h (62 mph) is just 4.5 seconds.

8-speed Sport Automatic Transmission.
The 8-speed Sport Automatic transmission in the new BMW 6-Series Gran Coupe boasts a perfect combination of speed, flexibility, sportiness, and efficiency. What sets it apart are its minimal torque converter slip and rapid gear changes. An innovative gear set configuration allows this transmission to offer eight gears, maximizing acceleration at any road speed, yet allowing the driver to conserve fuel by cruising at low revs. Befitting the Gran Coupe's sporting character, the driver can choose to select gears manually via shift paddles on the standard Sport leather steering wheel.

In addition to the efficiency of the engine and 8-speed Sport Automatic transmission, an extensive range of BMW EfficientDynamics measures contribute to reducing fuel consumption and emissions. Brake Energy Regeneration, engine Auto Start-Stop, on-demand operation of ancillary components, intelligent lightweight construction and extensive aerodynamic refinement collaborate to ensure maximum efficiency.

Chassis Management and optional Integral Active Steering.
Cutting-edge chassis technology gives the new BMW 6-Series Gran Coupe the tools to provide both sporty handling and exceptional comfort. The double wishbone front axle and the multi-link rear axle are made predominantly from aluminum. The chassis is geared to the requirements of drivers with sporting intentions, although the dampers also respond sensitively to bumps in the road surface under high lateral acceleration. The optional Active Roll Stabilization combines with the standard Dynamic Damper Control to offer the driver even more precise responses and perfectly flat cornering ability. The electronically controlled shock absorbers adapt to the road surface and the driver's style to perfectly control the car's body motions.

The electronically controlled damper system in the new BMW 6-Series Gran Coupe adjusts compression and rebound settings continuously and independently. For example, a stiff chassis setting can be combined with comfortable responses to unevenness in the road surface. The control unit of the damping system processes the data supplied by sensors on the vertical motion of the wheels as well as the ride height of the car. The driving speed and the damper setting chosen by the driver are also taken into account in calculating the damping force required for each individual wheel to even out body movements. This data is fed back to the shock-absorber units at intervals of just 2.5 milliseconds.

The optional Active Roll Stabilization feature reduces body roll in corners and in sudden changes of direction, or transitions. Sensors calculate the amount of body roll based on the driving situation at hand, and this is then counteracted quickly and precisely by hydraulic rotary actuators in the front and rear anti-roll bars. The result is flatter cornering inspiring greater confidence for the driver as well as greater comfort for the passengers during spirited drives. The power steering features standard Servotronic vehicle-speed sensitive assistance, and serves up the familiar BMW recipe of precision, comfort and linear response.

The Gran Coupe is also available with Integral Active Steering. This system (also available on the 6-Series Coupe and Convertible) combines the Active Steering system for the front axle with a steerable rear axle. Precisely harmonized steering angle movements at both axles create a virtual lengthening or shortening of the vehicle's wheelbase, which fosters both greater high-speed stability and enhanced maneuverability for parking and city use.

Brakes, Wheels, and Tires.
The lightweight floating-caliper brakes feature vented discs and Dynamic Stability Control. DSC brings together technology such as the Anti-lock Braking System, Dynamic Traction Control, Cornering Brake Control, Dynamic Brake Control, the Start-off Assistant, the automatic Brake Drying function and Brake Fade Compensation. Standard equipment also includes 8.0 x18-inch light-alloy wheels, with all-season runflat tires (size 245/45 R18) and a tire pressure monitoring system.

Driving Dynamics Control with ECO PRO mode: Extra-sporty to the most fuel-efficient driving modes - at the press of a button.

The new 6-Series Gran Coupe offers impressive driving dynamics combined with new standards of comfort in the premium segment. This is a result of superbly tuned suspension which achieves an astonishing balance between dynamics and comfort. On top of this, drivers are also able to vary the overall character of the car depending on the driving situation or to suit their personal preferences. As well as sportier or more comfortable drive settings, they can also opt for extra fuel efficiency. The different modes are selected using the new Driving Dynamics Control function including ECO PRO mode, which is standard on all 6-Series models. The driver can choose settings of COMFORT+, COMFORT, SPORT, SPORT+ and ECO PRO modes using the large rocker switch on the center console. Affected parameters include the tuning of the throttle response, power steering boost assistance, shock absorbers, automatic transmission shift characteristics and - if equipped - roll stabilization and Integral Active Steering. In SPORT+ mode, the Dynamic Traction Control mode of the standard Dynamic Stability Control system is activated, raising the thresholds for stability intervention in the most sport-oriented driving circumstances.

The new ECO PRO mode, meanwhile, supports an extra-efficient and economy-conscious driving style. It does this by changing the accelerator mapping so that the same pedal travel delivers less power than in the standard mode. Also in this mode, the automatic transmission control strategy is modified so as to upshift sooner and to delay downshifts, while intelligent energy and climate management reduces the mechanical power consumption and also the consumption of electrical systems such as heated mirrors and seats. But the biggest potential for improving fuel economy comes from the driver's own personal driving habits. Special displays in the instrument cluster let the driver know by how much the driving range is being extended, show fuel consumption history, or, with reference to the specific driving situation, provide tips and incentives on how to develop a more economy-conscious driving style. ECO PRO mode allows average fuel consumption to be reduced by up to 20%, with a corresponding increase in driving range.

Design: Athletic elegance, natural sportiness.
The new BMW 6-Series Gran Coupe again heralds the arrival of an exceptionally sporty and exclusive 4-seater in the premium coupe segment. The new model's extra length and width over its 2 door model combine with its low height (2.8 inches lower than a 5-Series) to produce a strikingly low-set and powerful design. This new interpretation of the traditional BMW Coupe proportions is embellished by lines and surfaces inspired by the movement of waves. Flowing lines and harmonious curves create a feeling of athletic grace which underline the opulent character and elegant appearance of the four-door BMW.

The expressive front end is dominated by the large and slightly forward-slanting BMW kidney grille. The grille emphasizes the car's sporting pedigree with a broad, flat design, and creates a visual connection with the engine nestling behind. The kidney grille slats, angled slightly towards the top, lend additional emphasis to the front end's "shark nose" character. The contour lines of the hood converge towards the kidney grille, forming a V-shape which is continued by the contours of the headlights, kidney and wide air intake to give a road-focused look.

Powerfully flared wheel arches and the LED foglamps, placed well to the outside, accentuate the width of the front end. The lower air intake is split into three sections by model-specific L-shaped electroplated bars, which pick up the contours of the hood lines and BMW kidney grille to add extra intensity to the road-focused stance of the front end.

High-visibility innovation: Adaptive LED Headlights.
The new Gran Coupe is equipped with Adaptive Xenon headlights as standard. An accentuating trim element cuts across the top of the hallmark BMW twin round headlights to produce the purposeful look familiar from other BMW models. The optional Adaptive LED Headlights provide a fresh take on this established feature. The Adaptive LED Headlights for low beam and high beam contain LED light rings for the parking lights and daytime running lights, which are flattened on the lower edge and overlapped at their top edge by an accent light - also featuring LEDs. The result is a stunning, distinctively BMW showcase for the innovative light technology. In addition, they also generate the low beam and high beam light from the two light rings. The light sources are horizontal LED ribs positioned in the center of the light rings. The brand's hallmark twin round headlight look is therefore expressed even more strikingly - not only with the daytime running lights switched on, but also when the headlights are activated in the dark.

However, the Adaptive LED Headlights are about more than just looking good; they also ensure the driver has optimum visibility. Their bright white light provides a bright and even illumination of the road ahead. From a color perspective, the light comes much closer to natural daylight than that created by conventional halogen or xenon headlights, lending even reflective objects far greater contrast. The cornering element of the Adaptive LED Headlights is also tailored to the car's speed, steering angle and yaw rate, allowing the pivot of the headlights to adapt automatically to the line of the corner. Meanwhile, a light source positioned specially in the headlight housing generates the cornering light which, at low speeds, ensures illumination of the road surface in the direction the car is turning. LED technology is also deployed for the turn signal indicators, each of which consists of eight LED units arranged in a row underneath the light rings. As well as enhancing visibility in the dark, the Adaptive LED Headlights also significantly improve the signaling effect of the car's lights.

Side view: Elegant roofline, powerfully curved surfaces.
With its long, powerfully contoured hood, set-back passenger compartment, long wheelbase and short overhangs, the BMW 6-Series Gran Coupe presents a fresh take on the hallmark BMW proportions. The Gran Coupe's distinctive appearance is dominated by its four-door layout, longer wheelbase than other BMW 6-Series models and likewise longer passenger compartment. The low, elegantly stretched roof line, which flows smoothly into the rear end, is a similarly eye-catching and distinctive feature of the new model's silhouette.

The combination of sportiness, style and luxury is particularly clear when viewed from the side. Longer side window surfaces than those found on the two-door BMW 6-Series models hint at the extra space available in the rear compartment. Side windows extending far back into the C-pillar give the passenger compartment the low-slung, stretched look typical of Coupes. The more generous greenhouse also allow light to flood the interior, further enhancing the feeling of space inside and all-round visibility for the rear passengers. High-quality Chrome Line Exterior surrounds for the side windows complement the coupe style window line. The hallmark BMW Hofmeister kink at the transition to the C-pillar is given an extra touch of style in the form of etched "Gran Coupe" model lettering set against a sporty texture in the rear section of the side window.

Powerfully flowing surfaces - which open out as they extend back from the front end and stretch over the full length of the body before feeding into the muscular rear end - give the BMW 6-Series Gran Coupe a naturally sporty look. The character line streaming out from the gill on the front wheel arch takes in the door handle and runs the full length of the car, emphasizing the athletic elegance of its side view. Around the rear wheels, the surfaces below the character line push outwards, enhancing the impression of a powerful car with a strong, assured stance on the road. Plus, the light surfaces generated above the rear wheel arches draw further attention to the wide track and the power being channelled through the rear wheels.

Another character line, emerging from the curvature of the front wheel arch, drops down between the gill feature and the door, before levelling out and extending horizontally to the rear. The unbroken shadow surface above the side sill emphasises the car's muscular stance from the side.

The rear-end design: horizontal lines and clean surfaces.
Clearly structured surfaces and horizontal lines add further presence to the car's powerful rear end, which acts as a pointer to the BMW 6-Series Gran Coupe's impressive roadholding and the sporting nature of the vehicle concept as a whole. The lines of the rear end become noticeably broader as they blend into the wheel arches bulge. All of which gives the rear view an extremely low visual center of gravity. The conspicuously flared wheel arches spotlight the car's wide track and underline the horizontally structured character of the rear. The trunk lid and rear fascia both have flatter surfacing than their counterparts on the other BMW 6-Series models. The more clearly sculpted sill emphasises the overall volume of the rear end and brings striking details such as the rear lights and exhaust tailpipes more clearly into view.

The two-part, L-shaped rear lights share the contours of the car's BMW 6-Series siblings and each use a pair of LED light strips to generate the distinctive night-time look of a BMW. The third brake light is integrated into the roof and stretches the full length of the rear window.

Audi S5 Sportback, 2012

 

 

 

 

• Audi S5 Sportback, 2012

A button is used to directly adjust the optional seat heating and seat ventilation in three stages. Also updated were the ignition key, the selector lever for the automatic transmission, the button for the optional Audi drive select system and the controls of the high-efficiency air conditioning and multifunction steering wheel. All displays are now illuminated in white.

New paint covers the bezels on the instrument cluster and the center console, and there is also a new selection of upholstery and inlays. The latter are available in Aluminium Trigon or in walnut or natural fine grain ash. Almost all of the interior colors are new. Fine Nappa leather replaces Valcona in the Sportback, and the armrests can also be covered in leather, if desired. The Audi A5 Sportback is also now optionally available as a five-seater.

Other attractive option is the S line sport package. It drapes the interior in black and accentuates it with elegant applications. A sport suspension lowers the vehicle body by 10 millimeters (0.39 in), and 18-inch wheels round out the package. Buyers looking for that special something will find many more customization options in the Audi exclusive range, including the stylish Audi exclusive line with two-tone seat coverings.

Engines
The Audi A5 family sets new standards for sportiness and efficiency. All engines feature forced induction and direct injection for tremendous pulling power. Even the entry-level engine produces 320 Nm (236.02 lb-ft) of torque. The start-stop system and the recuperation system are standard with all engines - no other manufacturer takes such a rigorous approach. The lineup comprises three gasoline engines and four TDI units. CO2 emissions have been reduced by as much as 22 percent.

The completely redesigned 1.8 TFSI showcases the full extent of Audi's expertise. Groundbreaking innovations can be found in the control of the valves and their lift, the thermal management concept, the injection system, the turbocharger and the integration of the exhaust manifold. In the Audi A5 Coupé, the high-end four-cylinder unit consumes on average just 5.7 liters of fuel per 100 km (41.27 US mpg). This best-in-class value corresponds to 134 grams CO2 per km (215.65 g/mile) and is 21 percent lower than before. With 125 kW (170 hp), the 1.8 TFSI accelerates the A5 powerfully.

The output of the 2.0 TFSI remains unchanged at 155 kW (211 hp). New to the Audi A5 lineup is the 3.0 TFSI, a supercharged V6 producing 200 kW (272 hp).

The diesel engines are also impressively efficient, and the four-cylinder units feature modifications in numerous areas. Equipped with the 130 kW (177 hp) 2.0 TDI and a manual transmission, the Audi A5 Coupé consumes on average just 4.7 liters of fuel per 100 km (50.05 US mpg) - a CO2 equivalent of 122 g per km (196.34 g/mile) and a milestone in the coupe segment.

Three V6 diesel units round out the lineup on the top end. The 3.0 TDI with 150 kW (204 hp) is the most fuel-efficient six-cylinder unit in its class worldwide. In the Audi A5 Coupé with multitronic, it consumes on average 4.9 liters (48 US mpg) of fuel and emits just 129 grams CO2 per km (207.61 g/mile). The second variant of the 3.0 TDI produces 180 kW (245 hp). Arriving somewhat later is a particularly low-emissions clean diesel model that will make the Audi A5 the first coupe on the market to meet the Euro 6 diesel standard.

Drivetrain
Audi offers the ideal drivetrain for each engine. A manual six-speed transmission and the continuously variable multitronic are available for models with front-wheel drive. The quattro models come with a manual transmission or the lightning-fast, seven-speed S tronic. All of the transmissions shine with their convenience and precision, high efficiency and wide gear spread. The long ratios in the upper gears reduce fuel consumption.

Members of the Audi A5 family equipped with quattro permanent all-wheel drive and the S tronic transmission also feature the crown-gear center differential with torque vectoring. During normal driving, the mechanical component sends the engine's power primarily to the rear wheels. If necessary, it redistributes the power lightning-fast and smoothly. Up to 70 percent can flow to the front axle, 85 percent to the rear axle. Torque vectoring uses targeted, minor braking interventions to make the handling even more precise.

Available as an option in all Audi A5 quattro models, the sport differential provides for maximum precision and high traction. It uses two superposition stages engaged via multi-plate clutches to actively distribute the torque between the rear wheels as needed.

Chassis
The Audi A5 models set standards for sporty dynamics, luxurious ride comfort and excellent driving safety. Most of the components of the five-link front suspension and the trapezoidal-link rear suspension are made of aluminum. The rear suspension bearings and the damper tuning have been updated for more precise handling and even greater comfort.

The ESP stabilization program with electronic limited slip differential is standard in all front-wheel drive versions of the Audi A5. ESP uses minimal braking interventions at the inside front wheel for even more agility during dynamic driving. The large brakes - with ventilated front and rear discs in many variants - offer excellent stopping power and are very easy to modulate.

17-inch wheels with 225/50 tires are standard. Options include wheels up to 20 inches and 265/30 tires as well as four new wheel designs.

Among the high-end features in the model series is Audi drive select. In the basic configuration, it adjusts the power steering boost, the accelerator characteristic, the shift points of the automatic transmission and the automatic air conditioning. Using a button in the cockpit, the driver can determine whether these components should work in "comfort," "auto," "dynamic" or "efficiency" mode. The latter helps to drive the Audi A5 particularly efficiently. If the car is equipped with a navigation system, there is also an "individual" mode that the driver can largely configure him or herself.

Audi drive select can be combined with additional modules, if desired. These are the sport suspension with damper control, the sport differential and dynamic steering, which steplessly varies the steering ratio by nearly 100 percent as a function of speed.

Another new standard feature in the Audi A5 model series is the electromechanical power steering. An electric motor generates the right amount of boost for the speed being driven. The electromechanical power steering features a direct ratio, reacts instantly and provides precise road feedback. It intervenes slightly to support the driver when braking on a surface with less grip on one side of the car.

The system reduces fuel consumption by up to 0.3 liters per 100 km and up to 7 g CO2/km (11.27 g/mile) because it consumes no energy at all while driving straight.

Assistance systems
The assistance systems in the Audi A5 model series use a variety of technologies to make driving even more controlled. Some of them have been improved with new functions. Among the standard features is the new driver information system with recommendations to take a break. It uses steering motions and additional parameters to detect when the driver is getting tired and issues an appropriate warning.

Audi side assist supports the driver when changing lanes by using radar to monitor the space behind the car. Audi active lane assist - a new feature in the Audi A5 - helps the driver to maintain the lane. A camera detects the lane markings and the system makes slight corrections to the electromechanical steering, if necessary. The adaptive cruise control uses radar technology to maintain a constant interval between the Audi A5 and the vehicle ahead. At speeds below 30 km/h (18.64 mph), it initiates maximum braking in the event of an impending collision.

Infotainment systems
The infotainment systems in the Audi A5 have been significantly upgraded. Audi equips all models in the A5 lineup with a CD radio and eight speakers.

The optional top-of-the-line unit is MMI navigation plus with a large hard drive, seven-inch color monitor, 3D graphics and DVD player. Its controls have been improved. The number of hard buttons has been reduced from eight to four and the volume control now features a joystick cap to make it easier to choose songs. Voice control and digital radio reception also received some fine-tuning.

An additional option is the Bluetooth online car phone. Audi connect is the catchword for the attractive services this phone brings to the A5, which include Google POI search, navigation with Google Earth images and a WLAN hotspot. The hotspot enables passengers to surf the Internet and send and receive e-mail with their mobile devices. Audi traffic information online is an additional service that does a much better job than the familiar TMC standard of providing the driver with extremely precise and current information about the traffic load along the selected route. All the driver needs to use these functions is a data-capable SIM card.

Prices
Despite the extensive product improvement, Audi is raising prices only slightly. The price increase for the Audi A5 Coupé 2.0 TFSI is only €200, for example. The base model, the Audi A5 Sportback 1.8 TFSI, costs €33,350.

The Audi S5
The top models in the series - the S5 as Sportback, Coupé and Cabriolet - have also been refreshed. All S5 models, including the Coupé, are now equipped with the 3.0 TFSI producing 245 kW (333 hp). Compared to the 4.2-liter V8 it replaces in the Coupé, the supercharged V6 consumes on average 20 percent less fuel per 100 kilometers. Average fuel consumption is just 8.1 liters (29.04 US mpg) while performance remains impressive. The S5 Coupé accelerates from 0 to 100 km/h (62.14 mph) in just 4.9 seconds on its way to an electronically governed top speed of 250 km/h (155.34 mph).

Visual cues to the updated S models include new lights, modified body details and new crystal-effect paint finishes. Subtle changes can also be found in the interior. The most important technical updates for the Audi S5 are quattro drive with the crown-gear center differential and electromechanical power steering. The special S sport suspension and the standard 18-inch wheels deliver the power to the road.

Porsche 911 Carrera 4 Cabriolet, 2013

 

 

• Porsche 911 Carrera 4 Cabriolet, 2013

The new Porsche 911 Carrera 4 unites the excellent performance and efficiency of the new generation of the 911 Carrera with the dynamic benefits of the latest version of the active all-wheel drive system PTM (Porsche Traction Management). The typical Porsche all-wheel drive with rear-focused layout in this latest 911 version guarantees maximum vehicle dynamics on a wide variety of road surfaces and in all weather conditions. The new 911 Carrera 4 models deliver traction and dynamic performance the power of four.

The new all-wheel drive 911 is being launched on the market in four versions - as the Porsche 911 Carrera 4 and 911 Carrera 4S and each as Coupé and Cabriolet. They sport the same traits as the rear-wheel drive versions: their lightweight body design, suspension, engines and gearboxes are identical, the only exception being modifications related to the all-wheel drive. This means that despite a higher level of engine and driving performance, all four models consume significantly less fuel than the previous models; total savings for individual versions are as much as 16 per cent. In addition, the new 911 Carrera 4 is up to 65 kg lighter in weight.

The most distinct identifying feature of the 911 with all-wheel drive is still the wide rear section: compared to the two-wheel drive 911 Carrera models, the rear wheel housings each extend further outward by 22 mm, and the rear tyres are each ten millimetres wider. The traditional red light band that connects the two taillights has also taken on a new form.

Porsche Intelligent Performance: high levels of driving performance, low fuel consumption
All new models have a 7-speed manual gearbox as standard, and the Porsche Doppelkupplung (PDK) gearbox is available as an option. The 911 Carrera 4 Coupé with 350 hp (257 kW) can sprint from zero to 100 km/h in as little as 4.5 seconds (Cabriolet: 4.7 s) and reach a top speed of up to 285 km/h (Cabriolet: 282 km/h), depending on equipment features. Fuel consumption with PDK is 8.6 l/100 km (CO2 203 g/km) for the Coupé and 8.7 l/100 km (CO2 205 g/km) for the Cabriolet.

The Coupé and Cabriolet of the 911 Carrera 4S each have a 3.8-litre rear-mounted boxer engine that produces 400 hp (294 kW); this enables acceleration to 100 km/h in 4.1 seconds (Cabriolet: 4.3 seconds) and a top speed of 299 km/h (Cabriolet: 296 km/h) with a suitable equipment configuration. Fuel consumption values with PDK are 9.1 l/100 km (CO2 215 g/km) for the Coupé and 9.2 l/100 km (CO2 217 g/km) for the Cabriolet.

New: all-wheel drive indicator, Porsche Active Safe, sliding glass sunroof, extended Sport Chrono pack
In the new Porsche 911 Carrera 4, a new menu in the instrument cluster informs the driver how the PTM all-wheel drive is currently distributing engine power. In addition, with the debut of the 911 Carrera all-wheel drive models Porsche is introducing the optional Adaptive Cruise Control (ACC) to the entire model range, which controls distance to traffic ahead and vehicle speed. When ordered with PDK, the ACC system adds the safety function Porsche Active Safe (PAS), which helps to prevent front-end collisions. In addition, Porsche offers a new sliding glass sunroof as an optional feature for the 911 Carrera Coupé. Driving 911 cars with a manual gearbox and Sport Chrono pack can now be even sportier: In Sport Plus mode, the system automatically double-declutches during downshifts.

The new all-wheel drive models replace a very successful previous generation, of which a total of about 24,000 units have been sold since 2008. This represents a 34 per cent share of total sales of second generation 997 models. This previous generation launched with one of the greatest development steps in powertrain technology that the 911 with all-wheel drive ever made: new were the engines with direct petrol injection, Porsche Doppelkupplung (PDK) gearbox and electronically controlled Porsche Traction Management (PTM). In July 2011, Porsche crowned the model series with the 911 Carrera 4 GTS, whose 3.8-litre engine was boosted to 408 hp (300 kW).

World premiere at the 2012 Paris International Motor Show
The new Porsche 911 Carrera with all-wheel drive will make its first public appearance at the 2012 Paris International Motor Show. The new 911 models will launch at the end of 2012. Prices in Germany are 97,557 euros for the 911 Carrera 4 Coupé and 110,290 euros for the Cabriolet. The 911 Carrera 4S costs 112,313 euros as a Coupé and 125,046 euros as a Cabriolet. All prices include 19 per cent VAT and country-specific features.

•  Honda Odyssey, 2012

Completely redesigned for the 2011 model year, the 2012 Honda Odyssey remains the class-leading minivan for fuel economy and safety ratings, while continuing to offer the refinement, space and engaging driving experience that people have come to expect from this highly acclaimed family vehicle.

Class-leading achievements include the highest EPA highway fuel economy rating for an eight-passenger minivan of 28 mpg for Honda Odyssey Touring. Plus, all Odyssey models achieve the best possible safety ratings from both the National Highway Traffic Safety Administration (NHTSA) with a 5-Star Overall Vehicle Score and the Insurance Institute for Highway Safety (IIHS) with a TOP SAFETY PICK, an achievement that no other currently-tested minivan can match.

Designed and built in the United States, the five available models consist of the Honda Odyssey LX, EX, EX-L, Touring and Touring Elite, with each providing a unique combination of features, value, luxury and in-vehicle entertainment technology. Changes for 2012 include the addition of select features to the Odyssey EX that were previously exclusive to the Odyssey EX-L. For 2012, the Odyssey EX now includes Bluetooth HandsFreeLink, the intelligent Multi-Information Display (i-MID) with an 8-inch TFT screen, a 2-GB CD Library and a USB Audio Interface. The 2012 Odyssey Touring receives an exclusive exterior color, White Diamond Pearl, replacing Taffeta White on the prior model.

Body
The Honda Odyssey body uses a tapered cabin design with a signature "lightning bolt" character line to create a dynamic and distinctive appearance. Additionally, the styling cue creates a relatively large third-row window that enhances the outward perspective for third-row passengers. Engineered for a quiet interior, the Odyssey's highly-rigid body with 59 percent high-strength steel (an exceptional amount by industry standards) helps enhance the effectiveness of the vehicle's sound-deadening material to isolate road noise. The high-strength steel also helps to reduce body weight for better fuel economy and optimize body rigidity for agile handling.

Interior and Features
The interior offers multiple modes for accommodating child seats, adult passengers and cargo, along with offering a comprehensive range of in-vehicle entertainment technology. To fulfill its design goal to be the ultimate family vehicle, the interior provides three rows of comfort-oriented seating with generous sedan-like legroom in each row; along with providing up to five Lower Anchors and Tethers for CHildren (LATCH) positions for child seats (the Odyssey LX has four LATCH positions). The passenger volume measures 172.6 cu-ft. (Odyssey LX and EX) and the cargo volume ranges between 38.4 cu-ft. cargo volume (all seats up) to 148.5 cu-ft. depending on the seating configurations. A 4x8 sheet of plywood can fit inside the Odyssey's cargo bay with the second-row seats removed, and 10-foot-long 2x4 studs can fit inside the vehicle with the available front console removed.

To help enhance driver comfort, especially on long trips, the driver's seat features 10-way power adjustable seating (8-way power adjustable on Odyssey LX). A "3-mode" second-row seat design provides the ability to attach up to three child seats across the second row (Odyssey EX and above) by relocating the outboard seats to alternate positions closer to the doors. The one-motion, 60/40 split third-row Magic Seat, one of the Odyssey's original concepts and most versatile features, affords legroom for average size adults and is easy to open and close with one hand.

Highlights of standard features on all models include air conditioning with manual front and rear controls, power driver's seat, power windows with auto-up/down driver's and front-passenger's windows, tilt and telescopic steering column, a maintenance minder system and more. Honda Odyssey EX models and above come standard with power sliding rear doors, an "intelligent" Multi-Information Display (i-MID) with customizable wallpaper, center console storage, a flip-up trash bag ring, conversation mirror and more. Odyssey EX-L models include leather-trimmed seating surfaces (front and outboard second row), heated front seats, XM Radio®, power tailgate, a cool box, rearview camera and much more. Standard equipment on the Honda Odyssey Touring includes the Honda Satellite-Linked Navigation System, a Rear Entertainment System with a 9-inch display, driver's seat with two-position memory, 115 Volt power outlet, fog lights, parking sensors, six-speed automatic transmission and much more. The Odyssey Touring Elite adds an Ultra-Wide Rear Entertainment System (RES), blind-spot information system, High Intensity Discharge (HID) headlights and more.

Technology
Technology features available on certain models include a Honda Satellite-Linked Navigation System with Voice Recognition, which is available on the Odyssey EX-L and standard on the Odyssey Touring. The system features an 8-inch, high-resolution VGA color display and GPS technology to provide turn-by-turn guidance to a destination, in addition to other features including subscription-free FM Traffic data and a Zagat® restaurant guide.

Standard on the Honda Odyssey Touring Elite is the state-of-the-art, factory-integrated Rear Entertainment System that includes an ultra-wide 16.2-inch flip-down LCD screen and a 12-speaker, 650-Watt sound system capable of reproducing Dolby Digital 5.1 Surround Sound in 360-degree detail. A High-Definition Multimedia Interface (HDMI) video input and two wireless headphones for rear passengers are also provided. The Odyssey Touring Elite also includes the Blind Spot Information system (BSI), which helps alert the driver via indicators near the side mirrors when other vehicles are detected in set zones to the left and right of the Honda Odyssey.

Powertrain
An advanced 3.5-liter, 24-valve, SOHC, i-VTEC V-6 engine with Variable Cylinder Management (VCM) provides a balanced combination of performance, fuel economy and low emissions. The engine produces 248 hp (the most ever for Odyssey) and 250 lb-ft. of torque, while delivering an EPA-estimated city/highway/combined fuel economy of 19/28/22 mpg on Odyssey Touring models (18/27/21 mpg on Odyssey LX, EX and EX-L models). A 5-speed automatic transmission is standard on Odyssey LX, EX and EX-L models. Odyssey Touring models feature a 6-speed automatic transmission for enhanced driving refinement.

Chassis
A 118.1-inch wheelbase, a fully independent suspension design and features such as Vehicle Stability Assist (VSA®) with traction control contribute to the Honda Odyssey's confident driving performance and comfortable ride. The MacPherson strut front and multi-link rear suspension allows each wheel to maintain its own contact patch with the road, which is a significant benefit compared to less sophisticated torsion beam-style rear suspensions often used on other minivans.

Safety
The Honda Odyssey was recently named a TOP SAFETY PICK from IIHS, the institute's highest safety rating. The rating recognizes vehicles that do the best job of protecting vehicle occupants involved in front, side and rear crashes, plus rollover performance based on ratings in IIHS tests, as well as having a standard electronic stability control system. The Odyssey earned the highest-possible score of GOOD in all four ratings, including the rigorous roof-strength test. In addition to earning the TOP SAFETY PICK designation, the Odyssey was one of the first vehicles to achieve NHTSA's best-possible "Overall Vehicle Score" of 5 stars. The Honda Odyssey achieved its top "Overall Vehicle Score" with 5-star ratings for the frontal crash safety test and both side crash safety tests in all evaluated front and rear seating positions and scenarios. The Odyssey also received 4 stars for the rollover rating.

An extensive list of safety equipment includes the Advanced Compatibility Engineering (ACE) body structure, a Honda-exclusive body design that enhances occupant protection and crash compatibility in frontal collisions. Additional standard safety equipment includes: Vehicle Stability Assist (VSA); anti-lock brakes with electronic brake distribution (EBD) and Brake Assist; three-row side-curtain airbags with a rollover sensor; driver's and front passenger's side airbags with passenger-side Occupant Position Detection System (OPDS); and dual-stage, multiple-threshold front airbags.

Mercedes-Benz A-Class, 2013

 

 

 

 

 

• Mercedes-Benz A-Class, 2013

The new Mercedes-Benz A-Class is opening up a new chapter in the compact segment: markedly emotive in design, with powerful engines ranging from 80 kW (109 hp) to 155 kW (211 hp), extremely efficient with emissions from just 98 g of CO2/km and a best-in-class drag coefficient of 0.27. At the same time the new model underlines that for Mercedes-Benz, safety is not a question of price - the standard specification includes, amongst other things, the radar-based COLLISION PREVENTION ASSIST system. Prices in Germany start at €23,978.50 (incl. 19% VAT) for the A 180 BlueEFFICIENCY.

Exterior design: The most progressive design in the compact class
Standing as much as 18 centimetres lower on the road than the preceding model, the new A-Class communicates design and dynamism at the very first glance. This radical form language, presented and enthusiastically acclaimed around the world with the A-Class Concept, was consistently implemented in the series production car. The appearance of the new Mercedes-Benz A-Class reflects this new Mercedes-Benz design strategy. The result is what is known as a two-box design with a distinct character of its own, a sportily emotive exterior and an exceptionally high-quality feel to the interior.

Defined edges and tautly drawn surfaces mark out the exterior design of the new A-Class. The constant interplay between concave and convex surfaces creates a characteristic play of light, particularly along the sides of the car, which contributes to its unique appearance.

Typical features of the long, sporty front are its pronounced V-shape, the separate headlamps, the radiator grille with central Mercedes star and double slats to either side of the star, as well as the additional air intakes on the sides. The "dropping line" apparent in the side profile dissipates towards the vehicle's front end. The design of the headlamps, together with the configuration of the light functions within them, are a key element of the design concept.

The light modules and LEDs behind the headlamp cover glass have been arranged in such a way as to create the characteristic "flare effect" for the daytime driving lights and indicators. The so-called "flare" is made up of the feature line within the headlamp, the LED modules for the daytime running lamps and the bulb sets for the indicators. This signature effect gives the car its energetic look and so helps to define a new, youthful face for Mercedes.

The perfect interplay of dynamic design and excellent aerodynamics is nowhere more apparent than in the roof, with its smooth surfaces and taut, arcing curve. The silhouette reveals smooth, flowing lines finishing in a flat edge. The roof spoiler, which conveniently hides all the aerials, provides an extra sporty touch and gives structure to the roof assembly. The beltline rises to the rear to form a pronounced wedge-shape. The side view is distinguished by sensuously moulded sculptural side panels and crisp lines. The front structural edge, above the wing, falls in what is known as a "dropping line" in a gentle arc towards the rear. The powerfully-shaped shoulder muscles above the rear axle serve to emphasise the car's coupé-like character. A further line sweeps up from just in front of the rear wheel arch, then gently fades away. All these lines give depth and dynamism to the car's profile. Dynamic side sill panels provide a final finishing touch towards the bottom of the car, enhancing the appearance of elegant light-footedness.

The broad emphasis of the tail end is revealed in an interplay of convex-concave surfaces and edges. The tail lights continue the line of the muscular shoulders back towards the rear, while their horizontal orientation emphasises the car's powerful breadth. The light functions are provided optionally by fibre-optic cables and LED modules. Here, too, the interaction between design and aerodynamics is very clear: the surface finish of the tail lights is not only an interesting design feature, but also improves the airflow around the vehicle thanks to defined airflow break-away edges in the rear section.

Interior design: Extraordinary perceived value
The starting point for the interior design was the interior sculpture "Mercedes-Benz Aesthetics No. 2" presented at the Detroit Motor Show in 2011 and which directed attention to the new Mercedes-Benz design language in the vehicle interior, too. The first concrete implementation of this was shown in April 2011 with the A-Class Concept.

The process used for the production of this muscle allows diverse soft surface textures. It is thus possible to create different surface appearances with an attractive play of lights thanks to three-dimensional structures embedded in foil.

The instrument panel incorporates five round vents. "Like brilliant jewels they underscore the superior quality of the vehicle interior", explains Kaul. The outer rings of the round vents have a high-quality electroplated finish. The airflow direction is governed by an insert that is reminiscent of an aircraft turbine and reveals a meticulous attention to detail. This too has an electroplated finish in silver-chrome. The free-standing display screen features a black piano-lacquer-look front panel and a flush-fitting silver frame.

The instrument cluster comprises two large round instruments, each with a small dial set within it. When at rest, the dial needles stand at 6 o'clock. The pointer inlays are in white, although with the sportier design and equipment lines such as Urban and AMG Sport they are in red. The dials on the sporty equipment lines and packages are coloured silver with a chequered flag effect. The 3-spoke steering wheel comes with 12 function buttons and an electroplated bezel.

The centre dome and console, as well as the positioning of the various elements such as the head unit, lower control panel, air conditioning operating unit, stowage compartments, rotary pushbutton and armrest, reflect the findings of the ergonomics experts at Mercedes-Benz.

An extensive range of seat coverings, in terms of material (e.g. leather, fabric, ARTICO/fabric), colour combination and also geometry, provides scope for a broad range of individualisation options. Sports seats with integrated head restraints are available with all optional design and equipment lines. The sporty nature of the seats is emphasised by the opening between the upper edge of the seat backrest and the head restraint. On the back of the front seats this opening is edged with a frame in silver chrome and, in conjunction with the Light and Sight package, can also feature ambient lighting.

The chassis and suspension: Agility and refined sportiness
Refined sportiness means maximum agility combined with the sense of safety, unspoilt driving stability and high levels of ride comfort which are all typical of the brand. The suspension of the new Mercedes-Benz A-Class has a four-link rear axle, electromechanical power steering with assistance functions and ESP® with "Extended Traction Control" (XTC). During development, the suspension experts made intensive use of simulations and the driving simulators at the Mercedes development centre in Sindelfingen as part of the so-called digital ride and handling test.

The preconditions for achieving dynamic handling are excellent in the Mercedes-Benz A-Class. This is because compared with its predecessor the centre of gravity (24 mm lower) and seating position (174 mm lower) has been reduced significantly. A new feature is the four-link rear axle: forces are absorbed by three control arms and one trailing arm per wheel. This means that longitudinal and lateral dynamics are virtually independent of one another. Wheel carriers and spring links are made of aluminium to reduce the unsprung masses. The goal was to achieve high lateral agility with high driving stability thanks to small sideslip angle on the rear axle.

Three chassis and suspension set-ups are available: the comfort suspension and optional sports suspension for sporty yet comfortable handling (in conjunction with the Dynamic Handling package or the AMG Sport equipment line). In addition, the A 250 Sport has a sporty, "engineered by AMG" high-performance suspension. Altogether this results in low dynamic rolling behaviour and low start-off pitch angle. Furthermore, the vehicle also has a reduced tendency to understeer in the higher lateral acceleration range: the driver is therefore able to control changes in direction with low steering input but high steering precision. When accelerating out of bends taken at speed, the tendency to understeer is reduced even further by "Extended Traction Control" (XTC): with this function, ESP®provides support in the form of directional stability by generating a yaw moment on the front and rear wheels located on the inside of the bend.

Steering: mechanical with electric assistance
The electromechanical steering of the A-Class has been redesigned. The electric motor of the servo assistance system is now located directly on the steering gear as a dual pinion EPS system. The steering system makes an important contribution to the vehicle's overall efficiency, as the steering assist function only requires energy when steering actually takes place. A Direct-Steer system is available in combination with the Dynamic Handling package or AMG Sport equipment line. This provides a noticeably more direct steering ratio over the turning angle thanks to the variable ratio, and enhances the vehicle's handling and agility substantially. The steering conveys a high sense of safety, as the driver experiences a consistent and precise response to all steering movements.

The electric power steering also enables various steering assistance functions which are activated by the ESP control unit. These :

• Countersteering in case of oversteering
• Corrective steering when braking on road surfaces offering different levels of grip (split-fraction braking)
• Mitigating the extent to which the front-wheel drive influences the steering
• Compensating crosswind and road gradients
• The electric power steering also makes Active Park Assist possible.

With all engine variants, the Mercedes-Benz A-Class comes with disc brakes on all wheels. The callipers on the rear axle and the brake boosters are made of aluminium. A particularly convenient feature is the HOLD function, which is familiar from the larger model series: when stopping, for example at traffic lights, the driver merely has to press the brake pedal slightly more firmly and the brake will remain engaged until he moves off again. The brake is released automatically when the driver steps on the accelerator. On versions with manual transmission, the Hill Hold function automatically prevents the vehicle from rolling back unintentionally when starting on a slope.

The Mercedes-Benz A-Class is equipped with an electric parking brake, which operates by means of actuator motors acting on the callipers of the rear axle. The parking brake is activated via a button under the light switch on the left of the dashboard. This creates additional space in the centre console, as the handbrake lever is no longer required. When the button is pressed at speeds of over four km/h, the parking brake acts as an emergency brake, activating all four wheel brakes via the ESP®'s hydraulic unit.

In conjunction with the 7G-DCT automatic transmission, the parking brake offers a particularly convenient mode of functioning: when the driver accelerates sufficiently after fastening their seat belt, the parking brake is released automatically.

Aerodynamics: Saving fuel the aerodynamic way
With a drag coefficient (Cd) value of 0.27, the aerodynamic experts at Mercedes-Benz succeeded in creating another masterpiece with the Mercedes-Benz A-Class. And the A 180 BlueEFFICIENCY Edition due to follow later is even able to exceed this record for hatchback vehicles: thanks to a number of aerodynamic enhancements, this beacon of efficiency achieves a Cd value of 0.26.

Countless flow simulation studies on the computer and a great deal of fine tuning in the wind tunnel resulted in a clear goal: to enhance the basic shape of the A-Class design further, with a view to achieving an exceptional drag coefficient. This is no easy task, particularly for a hatchback model with a short rear overhang. But an improvement in the Cd value of just one hundredth will reduce fuel consumption by one tenth of a litre per 100 km when driving on the motorway at approx. 120 km/h. Based on NEDC figures, this corresponds to a CO2 reduction of one gram per kilometre.

With a Cd value of 0.27 and a frontal area of 2.20 m2, the drag area (CdA) is less than 0.6 m2 - a benchmark figure for hatchback vehicles in this segment.

The detailed work behind this development is highlighted by the following examples:

• The distinctive side spoilers next to the rear window ("finlets") help to create a run-on design which significantly reduces the disruptive longitudinal vortices generated at the D-pillars.
• Flow losses at the front wheel arches have been reduced substantially with the aid of patented serrated wheel spoilers at front and rear, slots in the wheel arches and optimised hub caps. These measures result in improved wind flow around the wheel arches.
• The Mercedes-Benz A-Class has an adjustable radiator shutter, already familiar in larger model series. The louvres behind the radiator grille are for the most part closed when there is no specific need for cooling air.
• The underbody has also been aerodynamically enhanced: the main floor panel features extensive cladding up to the rear wheel arch, followed by additional cladding of the rear axle. The rear silencer has also undergone aerodynamic optimisation.
• The new A-Class features exterior mirrors which have been optimised in terms of a number of details and already proven their excellent aerodynamic properties in large model series such as the S, E and C-Class, and also the B-Class. The position of the exterior mirror is adjusted in respect of the A-pillar in such a way that the airflow is directed along the side window without any significant interference or disruption.

The exterior mirrors and the low stepped height of the A-pillars reflect the fact that the work conducted in the wind tunnel was not just about optimising the flow conditions, but also about minimising wind noise. And in addition to aerodynamics and aeroacoustics, there is often another discipline to consider: in terms of water management too, the flow around the exterior mirrors and the A-pillars also has to be optimised in the wind tunnel in order to guarantee good visibility is maintained towards the rear and at the sides during wet weather.

More than with previous model series, in the case of the Mercedes-Benz A-Class the aerodynamics experts at Mercedes-Benz made particular use of flow simulation (CFD, Computational Fluid Dynamics): each component was first improved over several cycles using flow simulation before having its aerodynamic properties put to the test in the wind tunnel.

Digital flow simulation is based on so-called finite volumes as a mathematical model. A volume net is formed from around 60 million hexahedrons, or cubes, and is based around the CAD data of the new A-Class. This enables the driving cycle to be simulated over a free area in a large virtual wind tunnel. The Mercedes engineers generate the airflow using a predetermined turbulence level.

Setting new standards in terms of Cd value and consumption: BlueEFFICIENCY Edition
Due to follow later is the A 180 CDI BlueEFFICIENCY Edition boasting even better consumption levels. It is among the most efficient vehicles of its class: thanks to a series of additional aerodynamic optimisation measures, it has been possible to reduce its Cd value from 0.27 (standard model) to 0.26.

These measures include:

• partially covering the upper part of the radiator grille
• aerodynamically shaped spring link coverings to improve the underbody airflow at the rear axle
• lowering of the suspension by 15 mm

Diesel engines: three efficient power bands
The new basic engine in the OM 607 series develops 80 kW (109 hp), delivers 260 Nm to the crankshaft and with a manual transmission consumes 3.8 litres per 100 km, corresponding to 98 g of CO2/km. This is a 22-percent improvement over the only 60 kW (82 hp) preceding model, the A 160 CDI, which consumed 4.9 litres. The new top diesel, the A 220 CDI, is no less than 25 percent better than its predecessor: it develops an output of 125 kW (170 hp) and 350 Nm of torque, and in combination with the 7G-DCT automatic dual clutch transmission it consumes only 4.3 litres/100 km (provisional figure). The figures for the preceding A 200 CDI were 103 kW(140 hp), 5.7 litres, and 149 g of CO2/km.

Petrol engines: turbocharging and direct injection for all
A comparison between the new and previous A 200 demonstrates what has been achieved with the petrol engines: with 115 kW(156 hp) and 250 Nm of torque, the new engine delivers superior performance but consumes only 5.4 litres/100 km (127g CO2/km - figures for the 7G-DCT), which is 26 percent less than its predecessor (100 kW, 185 Nm, 7.4 l/100 km, 174 g CO2/km). Even the new top model with the 7G-DCT and producing 155 kW(211 hp) and 350 Nm is considerably more efficient with a consumption of 6.1 litres and CO2 emissions of 143 g.

The completely new engines and transmissions are not the only decisive factors in this exemplary efficiency. Thanks to the modular system it has been possible to select the optimally designed transmission for each diesel and petrol engine. The overall package is rounded off perfectly with progressive aerodynamics with a Cd figure of only 0.27, as well as a number of other improvements.

"The new four-cylinder models from Mercedes-Benz occupy a leading position by virtue of their performance, high efficiency and very low emissions. They impress with their smooth, superior power delivery and offer customers refinement at the highest level," says Professor Dr Thomas Weber, Daimler Board Member responsible for Group Research and Mercedes-Benz Cars Development.

The 7G-DCT dual clutch transmission: Dynamic and efficient
Drawing on over 50 years of experience in the development and production of automatic transmissions, Mercedes-Benz ventured into new technical territory with the 7G-DCT dual clutch transmission: the new system is an automated three-shaft manual transmission consisting of two subtransmissions, each with its own clutch. Both actuation of the clutches and gear shifting take place fully automatically and without any interruption in tractive power. This allows a particularly comfortable but nevertheless dynamic mode of driving.

Thanks to its seven gears it offers an exceptionally large spread of up to 7.99. This means that a very short transmission ratio is available when moving off on an uphill slope with a high payload, for example, while during cruising the engine speed can be lowered considerably. The efficiency of this transmission leads to a nine percent improvement in fuel consumption compared to the CVT employed in the Mercedes-Benz A-Class to date, and betters the consumption with a manual transmission.

At a length of 367 millimetres and a weight of 86 kilograms, the 7G-DCT is more compact and lighter than the transmissions in this torque class which have been available on the market to date. The clutches take the form of oil-cooled multi-disc clutches. The specially developed hydraulic fluid is actively cooled, thus ensuring correct functioning of the transmission even under extreme conditions, despite the comparatively low filling level of six litres. Excess engine heat can also be transferred to the transmission, which improves its efficiency.

For the first time on this type of unit, the transmission is supplied with oil by two oil pumps - one mechanical and one electric. The electric pump maintains the oil pressure when the engine is switched off via the start/stop function. This means that the transmission is immediately operational when the engine is restarted and the vehicle can move off again without any delay. In addition, the electric pump is able to support the mechanical pump when peak loads apply, enabling a more compact and efficient design for the mechanical pump.

Another new feature is electric activation of the hydraulics for the parking lock, which is locked by mechanical means. This "park by wire" function enables the transmission selector lever to be positioned as desired: it is located in the form of a steering column lever on the right behind the steering wheel in the A-Class. In combination with the electric parking brake, additional space has thus been created in the centre console for additional stowage facilities.

Three gearshift modes are available to the driver:

• ECONOMY: in this mode, the transmission performs gearshifts fully automatically and particularly comfortably. The gears are selected with due regard to a particularly economical style of driving at low revs
• SPORT: the transmission performs gearshifts fully automatically. The shift and response times are shorter, with gearshifts at higher engine speeds
• MANUAL: in this mode, the driver operates the transmission manually via shift paddles behind the steering wheel. The engine speeds at which the gears are shifted can therefore be freely chosen

In ECO or Sport mode, the driver is still able to intervene manually in the gear-shifting process via the shift paddles. The transmission reverts to the selected automatic mode after the paddles have remained inactive for twelve seconds, or after a longer delay when driving downhill or on winding roads.

A key factor contributing to the overall efficiency and dynamism of the A-Class is the closely coordinated operation of the transmissions and engines. A continuous exchange of data between the control units ensures that the engines run at the ideal operating point at all times. The 7G -DCT transmission is manufactured at Daimler's Stuttgart-Hedelfingen plant.

The six-speed manual transmission: Comfortable manual gearshifts
The new six-speed manual transmission was developed in parallel with 7G-DCT. It is extremely compact and shares a number of common parts.

The three-shaft transmission is also very compact (length 345 mm) and light (dry weight 46 kg) and incorporates a number of special features for particularly pleasant gearshifting. An integrated magnet on the gearshift shaft is detected by a Hall sensor. The idle position is identified in this way, making the start/stop function possible. The signal for reverse gear activates the reversing lights.

The large spread of 6.7 allows a reduction in engine speed while at the same time ensuring that sufficient tractive power is available when moving off with a fully laden Mercedes-Benz A-Class and trailer up to a gross weight of 3.4 tonnes. The clutch is operated hydraulically and the gears are actuated via cables.

The overhead camshaft with third and fourth gears and the reverse gear do not run in the oil bath. This reduces drag torque, thus facilitating gear shifting at low temperatures in particular. The three-cone synchronisation of the first two gears serves the same purpose, while the following gears are provided with two-cone synchronisation. The weight-optimised cast aluminium shift forks are installed on anti-friction bearings on the shift rods, in order to reduce the shift forces.

Passive safety: A strong basis and intelligent protection
"One star is all you need" - the Mercedes-Benz safety philosophy also applies to the new A-Class. Its safety equipment, some features of which are traditionally found in much higher vehicle categories, includes belt tensioners and belt force limiters for the rear seats, too, the PRE-SAFE® anticipatory occupant protection system and the active bonnet for pedestrian protection. The line-up also includes seven airbags as standard and the Mercedes automatic emergency call system.

The new Mercedes-Benz A-Class has passed the brand's rigorous programme of crash tests. This includes not only some 30 different impact configurations, which are laid down as requirements for safety ratings and international type approval, but also nine proprietary crash tests, such as the roof-drop test or the pole impact test, developed by the brand itself.

The ability of the new A-Class to satisfy requirements which go far beyond the statutory conditions in some cases is also demonstrated by an internal offset front collision test against a future luxury-segment saloon from Mercedes-Benz: despite the high impact speed and the fact that it is the smaller accident participant, the A-Class offers its occupants an intact passenger compartment and excellent chances of survival.

The bodyshell structure provides the basis for the high standard of passive safety, both in terms of material - the proportion of high-strength and ultra-high-strength sheet steel stands at 67 percent - and with regard to its structural design. Key features of the front-end structure are the systematic implementation of an available crash length of 435 millimetres, load distribution over several planes, the new bulkhead and floor concept and the subframe as a deformation element.

A total of three longitudinal member planes - consisting of the straight front longitudinal members, a second, upper plane attached to the front end consisting of extruded aluminium box sections and a third plane at the bottom in front of the subframe - allow impact energy to be reduced in a controlled manner.

The subframe provides the torque support for the transverse engine / transmission block and serves to attach the components for the front axle and steering. It consists of several steel plates, some in ultra-high-strength steel, and a hydroformed tube. In order to optimise its deformation properties, the subframe is connected via two aluminium struts leading forward to the aluminium radiator mount located under the front end. In the event of a frontal impact, forces can be discharged at an early juncture into the subframe via this third load path, in order to ensure the best possible energy dissipation.

A plastic crash wedge which is fitted at the rear of the front wheel arches helps to ensure that the wheels do not slide under the front doors in the event of a high-impact crash, irrespective of the turning angles. This means that it will be possible to open the doors, even after a serious accident.

The bulkhead also incorporates a special feature: so-called "skate runners" in front of the two middle longitudinal members discharge forces into the floor. The continuous floor structure consists of a total of four straight longitudinal members. The tunnel roof reinforcements at front and rear combine with the tunnel to provide a further closed profile supporting the front end.

Controlled deformation: protection in side-on crashes
Rigid side structures and defined deformation management help to safeguard the survival space for occupants in the event of a side impact. Elements here include the so-called "pole support", a member fitted diagonally in the rear footwell between centre tunnel and floor side wall which is intended to prevent the floor from being torn open in the event of side impact with a tree.

High-strength steels are used in the upper area of the B-pillar in order to minimise intrusion and to preserve the passenger cell in case of side impact. The lower area of the B-pillar is softer, in the interests of energy dissipation. The safety experts at Mercedes-Benz have christened the crack management system on the insides of the B-pillar "vampire teeth". In a serious side-on crash, the seat belt retractor presses against the inner wall of the B-pillar. To prevent this from leading to a transverse crack which might affect structural integrity, small, tooth-like recesses define the crack direction.

Pedestrian protection: comprehensive measures including Active Bonnet
The protection of those road users who are most at risk has always been a top priority during the development of Mercedes passenger cars. The new Mercedes-Benz A-Class features numerous protective measures designed to help lessen the risk of injury to pedestrians. In order to reduce the loads which arise in the event of a pedestrian impact on the bonnet of the vehicle, the deformation space between the bonnet and the components beneath it has been optimised. This is achieved in part through the appropriate positioning of components such as control units or fluid reservoirs in the engine compartment.

In the case of the A-Class, with its sporty, low-slung body, an active bonnet is also used. In the event of a pedestrian impact, sophisticated sensors combined with intelligent algorithms trigger actuators in the area of the bonnet hinges. These raise the bonnet by 65 millimetres. The additional space which this creates between the bonnet and the components in the engine compartment means that a head is subject to comparatively low internal acceleration forces on impact.

The deformation characteristics of the bonnet have been developed specifically to meet these requirements. Reductions in the impact loads can be achieved by using aluminium and reinforcing the inside face of the bonnet.

On all seats: intelligent restraint systems
The Mercedes-Benz A-Class protects its passengers with up to nine airbags. The standard complement comprises driver and front-passenger airbag, a kneebag for the driver, large thorax-pelvisbags incorporated in the seat to protect the chest, stomach and pelvis area and windowbags. The windowbags extend over both rows of seats to the A-pillar triangle. They serve to protect the occupants' heads from hard contact in the event of side impact and can also help to keep limbs inside the vehicle in an accident. The driver and front passenger airbags operate in two stages, according to the expected severity of the impact. The gas generator first of all fills the driver's airbag with 60 and the front passenger's airbag with 70 per cent gas. If a more severe impact is forecast, the second stage of the gas generator will additionally be activated after a delay and the airbags will be filled at a higher pressure level. Sidebags for the rear are optionally available.

The high safety expertise of the Mercedes-Benz A-Class's developers is reflected in a host of details. The deformable steering column yields by up to 100 millimetres when the driver exerts pressure on the airbag as a result of forward displacement in an accident, for example. The comfort features also reveal a fine touch: the driver's airbag is connected to a vibration absorber in the steering wheel to reduce vibrations, for example.

The head restraints for driver and front passenger are new developments. The onus in developing the new restraints was on further reducing the risk of whiplash injury. Key to effective whiplash prevention is the best possible adjustment of the distance from the rear of the occupants' heads. The restraint incorporates a button for this purpose on the left-hand side (as seen in the direction of travel). This release mechanism can be pressed to unlock the head restraint and increase the distance between head and head restraint. The button does not need to be pressed in order to reduce the distance. This enables single-handed operation in all adjustment positions.

Family-friendly: comprehensive precautionary measures in the rear
In developing the new A-Class, the Mercedes-Benz safety experts have also attached great importance to the safety of the rear-seat occupants. The new model therefore meets the relevant requirements of the Japanese and Chinese NCAP institutes which also take account of factors such as the ease of use of the rear seat belts. Experts believe that Euro NCAP will extend its rating programme to include rear-seat safety in the medium term. The A-Class is already prepared for this and is a role model in this respect - both within and beyond its own vehicle category - with features such as standard-fit belt tensioners and belt force limiters for the outer rear seats. A torsion bar in the roller mechanism twists when the load on it exceeds a defined level. In this way the belt force is limited and with it the load on the seat occupant.

The Mercedes-Benz A-Class's family-friendly features also include the ISOFIX child seat securing system on the outer seats. Child seats can additionally be fixed to the vehicle by means of special anchorage points with top tethers.

Innovation in the compact class: anticipatory occupant protection system
The PRE-SAFE anticipatory occupant protection system is available in the A-Class for the first time. This represents a further step in the on-going democratisation of this innovation, which was premiered in the S-Class in 2002.

PRE-SAFE® from Mercedes-Benz uses the time between detection of a potential accident situation and a possible collision to initiate preventive protection measures, thus reducing the loads exerted on the occupants in the event of a crash by up to 40 percent.

Core features of PRE-SAFE are reversible belt tensioning, the closing of side windows and sliding sunroof when critical lateral dynamics are detected and adjustment of the fully electric front passenger seat with memory function to an ideal position for maximum effectiveness of the restraint systems.

PRE-SAFE is activated when one of the following parameters is met: emergency braking, panic braking, pronounced over- or understeering, critical steering movements or heavy support by adaptive Brake Assist.

Mercedes-Benz automatic emergency call system: faster assistance at the scene of an accident
In combination with COMAND Online, the new Mercedes-Benz A-Class is equipped with the Mercedes-Benz emergency call system. As long as COMAND Online is connected to a mobile phone, the Mercedes-Benz emergency call system can automatically alert the emergency services within a matter of minutes in the event of a serious accident.

After the airbags or belt tensioners are triggered, the vehicle's exact GPS position and vehicle identification number (VIN) are sent by SMS to a special emergency centre, with positional data also being transmitted using the DTMF method (dual-tone multi-frequency) at the same time. Even if the occupants are unconscious or unsure of exactly where they are because they are on a holiday trip, for example, the emergency services alerted by the emergency centre will be notified quickly with accurate information. The driver can also make the emergency call manually as "MB emergency call" is always the first entry in the system phone directory.

On receiving the call, the emergency centre establishes voice contact with the vehicle occupants in a matter of seconds. A particularly practical aspect in an emergency is that the communication is held not in the language of the country where the accident has occurred but in the language which the driver has preset in COMAND Online.

Other than any mobile phone communication charges, which would only arise in the event of an actual emergency call, no charges are incurred by the driver for the emergency call facility and no contractual relationship - other than the regular mobile phone contract - is required.
