Vauxhall Insignia, 2014

 

 

 Vauxhall Insignia, 2014

The new Vauxhall Insignia range made its world debut at the 2013 Frankfurt Motor Show before first UK deliveries start in October 2013.
There are four new engines, including: a 99g/km 140PS 2.0 CDTi offering large cost benefits to fleet and high-mileage drivers; an all-new 1.6 SIDI 170PS Turbo petrol; and a new 250PS 2.0 SIDI Turbo petrol. Existing diesel units have also benefited from refinement improvements.

An all-new infotainment system, incorporating Bluetooth-operated internet connectivity, an 8-inch touchscreen, and 3D navigation and voice control, has full smartphone compatibility and allows drivers unrivalled communications while on the move. A DMB (Digital Media Broadcast) radio is now standard across the range.

Since its launch in 2008, the Vauxhall Insignia has largely dominated the mid-size sector and launched the eye-catching design philosophy that has permeated through all subsequent new Vauxhalls. The Insignia's classic exterior lines remain for the new range, refreshed styling at the back and front of the car, but inside there are important changes to its instrument cluster and centre console design, as well as improvements to control-functionality.

The Insignia's range has been simplified, too. There are now eight trims (down from 14 in the outgoing line-up), ranging from Design to Elite, with a mixture of new models that will appeal to both retail and fleet buyers. And like all Vauxhalls, the new Insignia range will come with Lifetime Warranty, allowing first owners peace of mind for as long as they own the car, up to 100,000 miles.

Vauxhall is raising its game in the highly competitive D-segment with the launch of the new Vauxhall Insignia. 167,000 Insignias have been sold since launch in the UK illustrating its popularity with both retail and fleet buyers, as well as its appeal to buyers who had only previously considered premium cars in the D-sector.

While the Insignia has increasingly found favour with retail buyers, much of its success has been in the fleet market with 80 per cent of Insignias going to business customers.

Vauxhall's combination of more efficient engines, premium design and state-of-the-art infotainment systems will certainly prove tempting to both company car drivers and fleet decision-makers alike.

The new Vauxhall Insignia's direct competitors include the VW Passat, Ford Mondeo, Toyota Avensis and Peugeot 508. Other potential competitors include the Audi A4, BMW 3-Series, and Mercedes C-Class.

Design and Aerodynamics
The biggest change existing Insignia customers will see when they sit in the new car is a completely re-designed centre console and instrument cluster. The centre console has been simplified and now has fewer buttons for more intuitive operation of common functions, such as air conditioning and infotainment, while the instrument cluster has new dials and a fresh, high-tech look.

Optional across the range is an 8-inch screen infotainment display (up from 5-inches in the outgoing range) and a new, upgraded instrument cluster with an 8-inch, high-resolution colour display. The cluster incorporates two outer dials showing fuel and revs, while in the centre sits a speedometer that can be displayed in analogue or digital form, or changed to show functions such as smartphone or audio use, or navigation.

The 8-inch infotainment display has touch-screen functionality, allowing drivers to access all functions and sub-menus such as radio stations, song titles, smartphone connection or 3D navigation in an intuitive and safe way. Its illuminated, touch-sensitive surface reacts immediately to finger movements, with even individual letters and numbers being accessible via this method. Up to 60 favourite menus can be stored from all functions and apps, available next year, can also be downloaded via the car's Bluetooth-connected internet.

In addition to button, touchscreen and touchpad operation, Insignia drivers can also control the infotainment system via re-designed controls on the new-look steering wheel. The advanced voice recognition function can also be operated by a single push of a button on the steering wheel.

Stylish new leather and cloth trims are available in the New Insignia range, complemented by upgraded dashboard materials and decors.

With 40 industry awards to its name - including the coveted European Car of the Year in 2009 - the outgoing Vauxhall Insignia has earned respect from media and customers alike. One of the pillars of its success has been its premium design - we called it 'sculptural artistry meets technical precision' at launch - and with the new range this has been enhanced still further.

Starting at the front of the car, the high-gloss chrome grille is wider and lower than before. The logo-bar that cradles the Griffin badge is thinner and includes winglets that link with the re-designed headlamps. On Elite models, these feature bi-xenon lamps with AFL (Advanced Forward Lighting), which is optional on all other models.

Standard headlamps are trimmed in high-gloss black with chrome-embedded accents, with the up-level AFL lights getting a 'wing-signature' daytime running light with energy-saving LEDs.

The lower front fascia inserts are designed to appear slim and wide to emphasise the upper grille size. Fog lamps are combined with wide, black inserts and chrome accents, which grow in width as they near the cabin.

The New Insignia range's Hatch and Saloon models are better defined through their unique tailgates and rear spoilers. The crease line on the C-pillar of the Hatch fades out before it reaches the spoiler's trailing edge, giving it a classic coupe silhouette. On the Saloon, the crease line continues along the edge of the spoiler to emphasise the body's length.

At the rear, the New Insignia range models appear wider and lower. The high-gloss chrome logo bar has been positioned lower on the tailgate. It extends into the tail-lights and incorporates the slim-look reversing lamps. The tail and stop functions of the two-piece tail-lights are illuminated by LEDs throughout the range.

The Sports Tourer's rear styling embodies a similar wider and lower appearance. The main visual enablers are again the stretched chrome brand bar, also framing the reverse functions, and an uninterrupted body-colored division between the tailgate glass and the longer, slimmer light units. The rear bumper moldings for all models also incorporate several black 'cut-out' inserts according to the powertrain choice, with or without visible exhaust tailpipes.

The New Vauxhall Insignia range offers a raft of technology, safety and comfort highlights. These include state-of-the-art radar and camera-based assistance systems (including adaptive cruise control and second-generation park assist), premium seats, and 'Open & Start', the keyless entry and start system, to name just a few.

Aerodynamics
Vauxhall's new Insignia is not only the lowest CO2 emitting car in its sector but now also the most streamlined vehicle in the world in its class.

Thanks to clever changes to the body design of the new Insignia, Vauxhall's engineers have reduced the vehicle's drag coefficient to under 0.25 for the Insignia hatchback and 0.28 for the Sports Tourer. New extended underbody covers, wider front spoiler lips, tail lamp housings designed to enhance airflow separation and an integrated rear deck lid spoiler contribute to the new Vauxhall Insignia's slippery shape.

Insignia 2.0 CDTi eco FLEX (120/140PS) models with Start/Stop also feature an additional, ultra-modern aerodynamic element: an active front air shutter. Air flowing through the front grille to cool the engine usually accounts for up to eight per cent of total vehicle air drag. To reduce this effect, a shutter in the lower front grille automatically closes to prevent air entering and causing turbulence. For cold starts, an additional advantage is a faster engine warm-up, which also helps reduce fuel consumption and CO2 emissions. Whenever the engine needs air for cooling, the shutter opens automatically.

These changes help the new Insignia eco FLEX (120/140PS) achieve class-leading CO2 emissions of 99g/km and 76.3mpg on the combined cycle.

This gives the eco FLEX a range of up to 1175 miles, which means that an average UK driver covering 8,200 miles, would only have to refill with diesel seven times per year. Or put another way, an eco FLEX driver could travel from London to Budapest on one tank of fuel!

ENGINES AND CHASSIS
The new Insignia range's powertrain line-up has been broadened still further with the addition of an all-new petrol engine and new derivatives of the existing 2.0 CDTi unit.

Now available with a choice of three power outputs - 120PS, 140PS and 163PS - the New Insignia range's 2.0 CDTi engine offers drivers ultra-low C02 emissions of 99g/km (76.3mpg combined) for the lower two outputs and 114g/km (65.7mpg combined) for the higher output unit (figures for Hatch models). But performance hasn't been compromised, with even the 120 and 140PS models producing up to 320 and 370Nm of torque respectively, and the 163PS model up to 380Nm.

For company car drivers, the new diesel engines offer an even more compelling argument, with both the 120 and 140PS eco FLEX Hatch versions emitting just 99g/km of C02 and dipping in to the 14 per cent Benefit-in-Kind category for the 2013/14 Tax Year.

Also new to the engine line-up are two direct injection petrol units: the new-generation 1.6-litre SIDI (Spark Ignition Direct Injection) producing 170PS/280Nm that recently launched in the 2013 Cascada convertible, and the 2.0-litre SIDI, producing 250PS/400Nm. Both engines provide an exceptional mix of refinement, economy and performance. They can be coupled with a six-speed manual transmission and Start/Stop function, or with a new, low-friction six-speed automatic gearbox.

Chassis
Across the New Vauxhall Insignia range, there have been improvements including dampers, roll-bars and steering, which result in improved noise and vibration behaviour and even higher levels of comfort. Completely new suspension control arms and carrier housings were built into the axle architecture to improve driving comfort. Electronic Power Steering (EPS) is standard in all but the VXR models has been reprogrammed for improved feel. Noise Vibration and Harshness (NVH) levels have also been reduced for enhanced occupant comfort.

Vauxhall's Flex Ride adaptive damping chassis system, with its real-time driving style recognition, is also used in the new Insignia. This innovative chassis networks all driving dynamics systems and features electronic damper adjustment, as well as speed-dependent power steering. The driver can choose between three driving modes: Standard for driving comfort, Tour for an even softer, more comfortable drive, and Sport for a more direct, sporty driving experience.

Vauxhall Mokka, 2013

 

 

 

•  Vauxhall Mokka, 2013

With a striking appearance, safe and spacious, the Vauxhall Mokka will appeal to a wide range of customers. Research has shown that the typical Mokka customer leads a very active lifestyle where leisure activities play a central role in his or her life. That is why the Mokka with its many optional extras, like the FlexFix bicycle carrier, is perfect for people who want to balance their busy daily lives with leisure activities.

The new Mokka SUV continues an unprecedented product revolution by Vauxhall and is set to make further waves with its bold, expressive design, advanced driving dynamics and technology.

Mokka adds a new sports utility vehicle (SUV) to the Vauxhall portfolio, and into the expanding compact SUV segment. Compact SUVs fall under 4.30 metres in length, distinguishing them from their larger counterparts. While many other segments are showing limited growth, the compact SUV market has grown by an impressive seven per cent (first half 2011 versus first half 2012). This rapidly growing segment, which includes the Skoda Yeti and the Nissan Juke and Qashqai, allows Vauxhall to break into brand new territory.

Just over half of all Mokka customers are expected to opt for the front-wheel drive variant, while the most popular engine the 1.7CDTi, accounting for 42 per cent of sales. The 1.4-litre turbocharged petrol engine and 1.6-litre will account for 20 per cent and 38 per cent of sales respectively.

Potential customers are also predicted to be technology-savvy people who rate safety and comfort features high on their agenda. The Vauxhall Mokka provides many technologies that are unique in the segment such as optional ergonomic premium seats, several front camera system functions and Adaptive Forward Lighting (AFL+).

The Vauxhall Mokka attract customers who are new to the brand. Typically the majority of compact SUV customers (75 per cent) are private buyers, while the rest are likely to be fleet and business. There's even a specific trim aimed at company car drivers, called Tech Line with prices starting from £15,995. Mokka Tech Line offers company car drivers exceptional levels of standard spec, combined with low P11D prices and attractive benefit-in-kind charges. Tech Line models can already be found in the Astra and Insignia model ranges.

Vauxhall is not new to the SUV market and has established a successful track record in this segment over the past two decades. In 1991, Vauxhall launched the all-wheel drive Frontera off-roader. British-built in Vauxhall's Luton plant, it was the first European combined off-roader and SUV model. A year later, the Vauxhall Monterey followed which was a mid-size pure off-road vehicle. After a brief absence from the SUV market, Vauxhall returned in 2006 with the Antara. This crossover model was updated in 2011 with a comprehensively refreshed appearance, powertrain line-up and ride and handling.

The Vauxhall Mokka is available in four trims: S, Exclusiv, Tech Line and SE, with prices starting from £15,995 on-the-road.

DESIGN
Bold and robust, the Vauxhall Mokka's solid, muscular exterior is complemented by design cues that are uniquely Vauxhall.

The front end features a pronounced front grille with a neatly tailored trademark chrome bar featuring the Vauxhall Griffin logo at its centre, framed by bi-xenon 'eagle eye' headlightsthat incorporate LED daytime running lights (standard on the SE).Protective cladding around the bumpers and wheel arches are set against Vauxhall's signature "blade" light catcher on the body side, sweeping upwards to the rear. Upper trim levels feature chrome window inserts and door handles, adding a premium touch.

At the rear, the Vauxhall Mokka has a skid plate in a polished aluminum finish. The rear window is combined with a roof spoiler and distinctly shaped tail lights. Roof rack panels emphasise the almost coupé-like roofline of the Mokka. A unique-in-segment option is Vauxhall's fully-integrated FlexFix bike carrier system, which can be stored in the rear bumper when not in use.

"The Mokka is very different to its competitors: it is small in size but big in attitude," said Malcolm Ward, Lead Design Director Vauxhall/Opel. "We are proud that we managed to develop a car that is perfectly designed for the urban environment while retaining typical SUV traits."

There is a broad offer of ten exterior paints including solid, brilliant, metallic and new three-coat premium colours. Solid colours include Royal Blue and there is the brilliant colour Summit White. The metallic colour range comprises Sovereign Silver, Carbon Flash, Borocay Blue, Velvet Red, Satin Steel Grey, Misty Lake and Deep Espresso Brown. Also available is a three-coat premium colour called Snowflake White.

Road clearance of 157mm makes driving the Mokka off road capable, with wide tracks of 1540mm reinforcing the SUV's muscular stance. Unlike any other model in the compact SUV segment, robust 18-inch alloy wheels are available as standard on all upper trim levels (Exclusiv, Tech Line and SE). Optional 19-inch wheels will also be available soon.

Interior
Inside, the new Mokka again reflects Vauxhall's sculptural design, with the signature wing-shaped instrument panel that wraps around the door inserts.

Splashes of chrome around the cabin centre are designed to give a premium feel. However, the Vauxhall Mokka is still practical and user friendly, with 19 storage spaces, including a cleverly concealed armrest in the rear bench that also contains a cup holder, and storage areas in front of and behind the gear leaver.

With up to 1,372 litre of loading space, the Mokka offers plenty of versatile features including a cleverly-designed parcel shelf which can be easily adjusted by hand and a rear bench that can be split and folded in a 60:40 ratio providing even more flexible loading and transportation. The Vauxhall Mokka is very much a driver's car with excellent ergonomics and comfort, a high seating position gives a great all-round view out of the vehicle and two-tone coloured, leather-trimmed seats are standard on the SE.

The range-topping Mokka SE has embossed two-tone coloured leather stitching as standard throughout its cabin. The instrument panel and doors are covered in a striking Tungsten Brush (Jet Black seats) or Sephia Bronze film. Customers can also opt for brown Cocoa/Saddle Up leather seats.

In S, Exclusiv and Tech Line trims, there is high quality woven Jet Black cloth or Cocoa/Dark Adriatic seat fabrics (depending on trim), soft seat inserts, a liquid platinum instrument panel and door décor moldings and chrome door release handles.

CHASSIS AND ENGINES
The handling of the all-new Vauxhall Mokka is involving and agile with a comfortable supple ride thanks to an intelligent chassis system with either front-wheel drive or adaptive AWD technology. The Mokka is available with a combination of fuel-efficient petrol and diesel engines with a choice of manual or automatic transmissions.

Chassis
Gerry Baker, Vauxhall's manager of vehicle dynamics based at Millbrook, was involved with Vauxhall Mokka chassis development from an early stage. "Early prototype cars were tested in the UK during 2011, to establish if bespoke damper settings were required for cars sold in Britain," said Gerry. "However, there was so little difference between the final UK and European settings that we opted for a common set-up for all cars. The same strategy was applied after steering tests in the UK, too. Finally, a large part of the Mokka's durability testing has been carried out at Millbrook."

To ensure maximum ride comfort and handling performance, Vauxhall engineers further developed, tried and tested MacPerson struts on the front axle.

Side load springs were added to compensate for lateral forces. Dual path strut mounts, strong stabilisers and double bonded handling bushings were also applied to improve handing and performance on the road as well as noise and vibration reduction. Damper and spring rates were sharpened in line with the characteristics of the Mokka chassis. 18-inch alloy wheels complete with 215/55 R 18 tyres are standard on the Exclusiv, Tech Line and SE trim levels.

On the rear suspension, Vauxhall's engineering team included a U-section tubular shaped torsion beam ahead of the wheels. This compound crank axle is developed with two different designs to fit the AWD and front-wheel drive variants. This allows drivers to experience best possible handling and body control for every powertrain. The dampers which are fixed behind the rear wheels ensure a good damper rate as well as an efficient damping performance. This ultimately means better handling and even more precise steering, giving the driver the best possible driving characteristics and control over the vehicle. Mini-block spring coils for the AWD variant ensure that the dampers can rebound even when fully loaded. In all the powertrain variants the Mokka can tow a payload of up to 1,200kg.

AWD System
The AWD system of the Vauxhall Mokka is efficient, intelligent and affordable for a broad segment of customers. The main components of the AWD system are the front axle differential, the drive shaft, the 4x4 rear axle drive and the control module as well as the electro-magnetic multi-plate clutch. Sensors constantly supply the control modules with data such as the yaw rate, lateral and longitudinal acceleration, steering angle, wheel speed, accelerator pedal position and engine revs and torque. Under normal conditions, when the road surface is dry, the front wheels drive the vehicle forwards, keeping fuel consumption low. Depending on the road conditions, the range varies from 100 per cent front-wheel drive to a maximum distribution of torque of 50 per cent on the front and rear axle when, for example, there is surface water or snow on the road.When traction requires it, the electronic torque transfer device (TTD) automatically and seamlessly sends torque to the rear wheels.

The AWD system further sharpens the Mokka's already agile handling characteristics. This is especially noticeable when the car has to negotiate corners at higher speeds or accelerate. It is activated automatically within a fraction of a second as soon as there is wheel slip due to a lack of traction. The AWD system with all its components weighs just 65kg, keeping the Mokka both efficient and eco-friendly.

Safety Technology
Ventilated brake discs measuring 300mm at the front and 268mm at the rear ensure high heat resistance and there is high brake performance in any situation. This was tried and tested under extreme conditions on the northern loop of the Nürburgring race track, in the Alps and on conventional roads. The brake discs are further supported by anti-lock braking (ABS) complete with cornering brake control and brake assist system as well as Electronic Brake force Distribution. The Electronic Stability Program (ESP®Plus) that is standard in the Mokka includes traction control and additionally Hill Start Assist (HSA) and Hill Descent Control (HDC). The latter ensures that speed is maintained when descending demanding hills with low friction, gravel or other difficult surfaces. It allows the driver to choose a suitable vehicle speed range from 3mph to 12mph.

The Hill Start Assist allows the car to take off and park more easily on a hill without the vehicle rolling backwards. To get the most out of the vehicle chassis, Vauxhall's engineers opted for state-of-the art Electric Power Steering (EPS) which is standard across the range. The EPS system features a precise wear adjustment system that has been optimised to fit the steering gear and reduces friction. The Vauxhall Mokka EPS system provides more speed sensitive steering assist with great responsiveness and at the same time offers lower fuel consumption than a hydraulic system. The steering column can be adjusted in its height and length so the driver can find his or her ideal seating position.

Engines
Mokka is available with a choice of three efficient engines. All manual transmissions are equipped with start/stop. Two petrol engines are available including a 1.6-litre (115PS) naturally aspirated engine with a five-speed manual transmission achieving 43.5mpg and combined CO2 emissions of 153 g/km. Torque is 155Nm at 4,000 rpm.

The second petrol unit is a 1.4-litre Turbo (140PS) that achieves 44.1mpg and combined CO2 of 149 g/km. AWD is standard and there is 200Nm of torque (at between 1,850 and 4,900 rpm). This engine has an alloy cylinder head and maintenance-free valve operation and is offered with a six-speed manual transmission. Later, it will be available with a six-speed automatic transmission. The manual six-speed 4x4 turbocharged Mokka reaches a top speed of 118mph and does 0-60mph in 9.4 seconds.

The turbocharged four-cylinder has an electronic engine control unit for even more precise combustion control as well as friction optimised components. Dual overhead camshafts with variable valve timing drive the four valves per cylinder. A variable-flow oil pump supplies the engine with the necessary lubrication. Saving even more fuel is the electronically controlled thermostat that ensures the best possible thermal engine management. When operating at full capacity it cools the engine, while during partial load operation it maintains a constant temperature.

Customers who prefer diesel engines can order the Mokka with a 1.7CDTi (130PS) turbocharged unit with a maximum torque of 300Nm (at between 2,000 and 2,500 rpm). This engine is available with a six-speed manual 'box with either front-wheel drive or AWD, or as a six-speed automatic with front-wheel drive. As a front-wheel drive with a manual gearbox the diesel unit achieves 62.8mpg and 120g/km CO2 emissions, making it one of the most fuel-efficient models in its segment. The performance figures speak for themselves: with a six-speed manual gear box and front-wheel drive the Vauxhall Mokka achieves a top speed of 116mph and does 60mph 10.5 seconds.

The 1.7CDTI engine has innovative "Clean Tech" technology with pressure sensors integrated in to the cylinders, ensuring best possible combustion control. The end result: a significant reduction of nitrogen oxides (NOx) and dust particles plus maximum fuel efficiency. A third generation common rail system operates with injection pressures of up to 1,600 bar. Electro-magnetic injectors ensure very precise combustion control.

Vauxhall's New Generation Engines
Vauxhall Mokka uses a second generation six-speed automatic transmission centred on increased efficiency (fuel consumption is down six per cent compared with its predecessor), a reduction of shift times and noise and vibration reduction. Thanks to a small torque converter, Vauxhall's engineers were able to reduce inertia. Optimised bearings, joint rings and friction elements also ensure a higher degree of effectiveness. A further key feature is the coil spring inside the torque converter. The spring rate was halved which improved the damping of vibrations.

Gear changes are possible on the six-speed automatic thanks to the ActiveSelect function, activiated by the touch of a button on the gear stick. The adaptive electronic transmission control comprises a range of intelligent functions: the automatic idling helps to save fuel. This function maintains the oil pressure at an optimum level during the first forward drive clutch movement. This is made possible by sensors and regulating devices that are variable depending on the engine speed and other data. Lower loads for the axle shafts and engine supports help to reduce the noise level. The hill program varies the electronic gear shifting parameters depending on the gradient of ascent or descent.

The latest generation of Vauxhall transmissions enables even more precise and smoother gear shifting. Vauxhall's engineers have shortened shift paths whilst at the same time reducing shift forces. To achieve this, the six-speed manual transmission was comprehensively reworked with new gearwheels and modified components including the input shaft and shift fork which ensures a smooth operation during cold and hot conditions. Friction forces on the gear leaver were also reduced. A red arrow also flashes in the instrument display which helps with driving at low rpms, saving fuel and reducing CO2 emissions.

Vauxhall Cascada, 2013

 

 

•  Vauxhall Cascada, 2013

Based on price, the Cascada's key competitors include the Volkswagen Eos and Golf Cabriolet, the BMW 1-Series Convertible and the Audi A3 Cabriolet. Vauxhall's latest offering is also longer than many other rival convertibles including premium offerings such as the Audi A5 Cabriolet and the BMW 3-Series Convertible.

At nearly 4.7 metres in length, the full size, four-seat, fabric-roof Cascada convertible is longer than an Audi A5 Convertible. It is also the first full-sized convertible designed, engineered and manufactured by Vauxhall since the 1930s. The all-new Vauxhall Cascada full-size convertible launches the company into a fourth new sector in a year, following on from its Ampera, Mokka and Adam models.

While the Cascada shares its dimensions with some full-sized convertibles, Vauxhall is positioning it in the C-sector due to its highly competitive pricing. The C-segment accounts for approximately one per cent of the total UK car market or around 21,000 units per annum and Vauxhall expects the Cascada to make up approximately ten per cent of this segment's volume per year.
As with all Vauxhalls, first Cascada owners will benefit from Lifetime Warranty, lasting the life of the car or up to 100,000 miles, whichever comes first.

DESIGN
Cascada's design team, originally headed by Brit Mark Adams, has created a car with classic lines, redolent of the Grandes Routieres (luxury touring cars) of a bygone age, matched with a capacious cabin and high-quality materials.

Exterior Design
At 4696mm long and 1839mm wide (excluding mirrors), Vauxhall Cascada has a broad stance and elegant lines. With the top down, it has a perfectly clean profile with no roof-top cover or visible roll-over protection disturbing the car's silhouette aft of the steeply-raked A-pillar.

The subtle 'blade' on the Cascada's lower body side is mirrored by a sharp crease that swings upward and meets with the wraparound rear light cluster. A gently rising waistline is highlighted by a chrome strip that borders the cockpit, marking the boundary between roof-top and body.

Sculpted with a purposeful power bulge, Cascada's bonnet tops a deep front grille with bold chrome applications. The fog lights are carried in two overturned 'sharkfin' elements, which are enhanced by chrome inserts. Using LED technology, the daytime running lights in the headlamps and the rear lights incorporate Vauxhall's 'wing' signature. In the rear, the LED modules are diffused to give a solid and sharp light signal - typical of cars in the premium sector. A chrome strip linking the boot-mounted light units matches a similar bar across the front of the car.

The Cascada's fabric roof can be specified in one of three colours, which can be coordinated with one of ten body colours. Other personalisation options include an array of six different alloy wheel choices with sizes up to 20-inch.

Interior
The Vauxhall Cascada's cabin mixes the well-equipped functionality of an Insignia's interior with handcrafted modules not found in any other Vauxhall.

Wrapped in a soft-touch material with high-quality stitching, the instrument cluster tops a wing-shaped panel which flows into the doors and frames the area around each front occupant. All-new, deeply contoured seats are available in a range of embossed fabrics and leathers, and customers have the option of ergonomic, Nappa-leather trimmed seats, which can be heated or ventilated. An Easy Entry system allows access to the rear seats, and electric seat belt presenters make securing front occupants less of a chore.

With a minimum load volume of 280 litres with the roof down, and up to 380 litres roof up, the Cascada is an exceptionally practical convertible. In addition, the rear seats benefit from Vauxhall's FlexFold system, which electrically releases and folds down the 50:50 split rear seats, allowing longer objects to be carried with ease.

In the cabin, several large storage spaces are available: one in each door and one under the instrument panel, and thanks to the use of a standard Electronic Park Brake across the range, a further cubby is located between the front seats.

CHASSIS, DYNAMICS & BODY CONSTRUCTION
Maximising torsional stiffness in a convertible's body is critical to maintaining a high standard of vehicle dynamics. Despite being significantly larger than Vauxhall's last convertible model, the TwinTop, by 71mm in its wheelbase and 56mm/70mm (front/rear) in its tracks, the Cascada's body is 43 per cent stiffer torsionally and 10 per cent more resistant to bending forces.

Targeted underbody strengthening helps the Cascada achieve these figures. Crossed steel bars are mounted to the Watt's link, across the B-pillars and front subframe, while high-strength tubular steel reinforcement sits inside each of the A-pillars. Collectively, these stiffen the body substantially, leading to precise handling and an exceptionally high degree of acoustic comfort.

Chassis
Vauxhall's HiPerStrut suspension has been adapted from the 325ps Insignia VXR and employed at the front of the Cascada. The HiPerStruts combine all the benefits of a conventional MacPherson strut set-up - compact packaging and light weight - but without the drawbacks of that system, such as torque-steer and a loss of traction under hard cornering. The HiPerStrut achieves this by a reduction in kingpin inclination, meaning no loss of negative camber during cornering, and therefore greater stability overall.

At the rear, the Cascada uses a combination of compound crank and Watt's link, with the thickness of each different model's axle beam varying to cater for different kerbweights. The Watt's link rods are connected to a cross member just behind the rear wheels' centre line. Any lateral force exerted on one side is compensated for by an equal force on the opposite wheel.

Cars using a compound crank and Watt's link are rare in the industry, but it's an innovative solution which provides a unique blend of excellent packaging and strong rear-end stability during cornering.

Unique steering programme for UK drivers
Precision, feedback and confidence. These were the three target elements for the Cascada's UK-specific steering programme. The challenge was to maintain the system's ease of use at lower speeds, but dial in a greater degree of involvement and slightly more effort at higher speeds.

The Cascada uses a rack and pinion steering system with speed sensitive assistance. But in order to provide drivers with more steering feedback, the system's electric motor is mounted directly on the steering rack, as opposed to the base of the steering column.

The key benefits of using electric power steering (EPS) are well known. At low speeds, the level of power assistance is increased to minimise steering effort. At higher speeds, assistance is automatically reduced to ensure a high degree of steering feel for the driver. The second important benefit is that, because it does not require an energy consuming hydraulic pump and responds directly to the amount of power needed at any speed, fuel consumption is also reduced.

FlexRide enhances Cascada's driver appeal still further
FlexRide, Vauxhall's adaptive damping system, will be available as a £790 option across the Cascada range, complementing the significant revisions to the new model's chassis. FlexRide automatically adapts to prevailing road surfaces and driving styles, providing drivers with fully optimised handling, even in the event of an emergency situation.

At the heart of FlexRide is the Driving Mode Control (DMC) which oversees and executes the system's settings, allowing the car to react to sudden changes in driving style or emergency situations. For example, if the driver needs to avoid an obstacle while in 'Tour' mode - the softest of the three settings - chassis sensors convey this to the DMC and the dampers are adjusted in a split second.

Standard mode (the default setting) reacts in the same way as Tour, but when drivers select Sport they not only get stiffer dampers, but more steering effort, sharper throttle response and an instrument panel that's back-lit in red, rather than white. Each of these settings can be dialled in or out of Sport mode via the Cascada's configurator.

ALL SEASON FUNCTIONALITY
Crucially for weather-hardened UK buyers, Vauxhall Cascada will feature a high-quality fabric hood, with optional superior acoustic and thermal insulation thanks to a special layer of polyester fleece between the outer and inner linings.

The key point of any convertible is the roof which on the Cascada is aerodynamically clean and refined, fits perfectly to the pillar less style of the car and disappears completely below a high quality tonneau cover when lowered. As well as reducing the vehicle weight by approximately 100kg compared to a hard top, the soft top also measurably lowers noise inside the car.

Making the Cascada a practical year-round car, the hood can be opened in just 17 seconds, at speeds up to 30mph by an interior switch, or via a button on the key fob.

The operating switch is conveniently located in the lower centre console. Operation is instinctive, the hand naturally dropping onto it, allowing the driver to keep his or her attention firmly on the road. All windows can be opened or closed and locked in just four seconds by operating the four-windows-switch.

Heavily tested by Vauxhall engineers, the electro-hydraulic mechanism for the roof has been opened and closed 15,000 times, corresponding to ten years of usage with four operations per day. The roof can be operated from -5 to +85 degrees Celsius.

Boot space of 280 litres when the roof is opened gives more flexibility to drive top-down even with big loads in the boot. Loading capacity can also be extended by 50:50 flex fold rear seats for longer and bigger objects with up to 750 litre loading capacity. This is not possible with other C Segment HardTop rivals.

Standard Soft Top
The standard two-layer soft top has a premium class three-layer exterior fabric made of highly-resistant polyacryl, an elastomeric rubber combining film and a backing fabric. Worldwide testing at extreme temperatures has proved that it is absolutely weather proof and insulation is superior to a retractable hard top. It needs no regular impregnation and is UV resistant so that it remains long-term colour fast, keeping the car looking good. The roof is also car wash proof.

The visible inside lining is made of woven polyacryl. Between these two layers is an insulating layer of air.

Acoustic Soft Top
The optional acoustic soft top offers even better noise and thermal comfort with acoustically enhanced exterior fabric and by adding a special layer of polyester fleece between the top layer and the interior lining. This improves thermal insulation and further reduces the noise level in the cabin by up to a third (-3 dB) helping to create a quieter and more relaxed interior ambience.

Detachable Windbreakers
A foldable windbreaker can be mounted behind the front seats. It is fixed on recesses in the side trim behind the rear seats and near the rear seat backrests. The upper part can be folded into vertical position to deflect wind, the horizontal part stays fixed, so the rear seats cannot be occupied when the front seat windbreaker is mounted.

A small windbreaker can be mounted between the rear head-rests to reduce drafts on the rear seats.

Both windbreakers come in a purpose-made bag that can be stored and fixed behind the rear seat backrests.

POWERTRAINS
The Vauxhall Cascada will come with a broad range of powerful and efficient engines. Starting the line-up is a 1.4-litre (140PS) Turbo petrol, with a manual gearbox, achieving a combined 44.8mpg and 148g/km CO2, and a 2.0-litre (165PS) diesel engine with manual and automatic transmissions, achieving up to 54.3mpg combined and 138g/km CO2. Both engines have start/stop technology.

But the highlight of Cascada's powertrain line-up is the all-new 1.6 SIDI Turbo ECOTEC petrol engine. The first production engine from Vauxhall's MGE (Mid-Size Gasoline Engine) family, the unit offers major improvements in torque, linearity and overall efficiency. It produces a maximum 170PS from 1650-3200rpm and up to 280Nm of torque, giving a 0-60 time of 9.2 seconds and top speed of 135mph. This engine will be available shortly after launch with a new, low-friction automatic six-speed gearbox that contributes towards combined fuel consumption of 39.2mpg and emissions of 168g/km.

To improve performance and refinement, one of the key engine development objectives for engineers was to lower overall levels of radiated noise and vibration, with no unusual sounds. Optimisation of the induction and exhaust systems included decoupling the cam cover from the cylinder head via specific fasteners, and a sealing system designed to resist high temperatures from the adjacent turbocharger.

With direct injection and pulsed combustion, engineers were able to substantially reduce noise levels compared to the previous engine. As a result of these 'sound-engineering' measures, customers will appreciate quiet and smooth idling, with a pleasant sound quality even at high road speeds, engine speeds and loads. The engine provides the perfect basis for gentle, smooth open-air cruising, while always keeping immediate propulsion power at the ready as needed.

A high-performance 2.0 (195PS) Bi-Turbo diesel engine with manual transmission will also be available shortly after launch. The Bi-Turbo achieves a combined 138g/km and 54.3mpg, yet accelerates from 0-60mph in just 8.9 seconds up to a top speed of 143mph.

New Generation Transmissions
In addition to impressive new engines, there are also new six-speed manual and automatic transmissions. The latest generation Vauxhall manual transmissions enable even more precise and smoother gear shifting. Engineers have achieved shorter shift patterns, while at the same time reducing shift forces. To achieve this, the six-speed manual transmission was comprehensively reworked with modifications to the shift mechanism. These measures focused on increased efficiency, with further improved precision, shift forces and comfort when the transmission is cold or hot.

The focal points in the development of the second generation six-speed automatic transmission are increased efficiency and faster shift times, together with lower noise and vibration. Thanks to a small torque converter, engineers were able to reduce inertia. Optimised bearings, joint rings and friction elements also ensure a higher degree of efficiency. A further key feature is the coil spring inside the torque converter, for which the spring rate has been halved to improve vibration damping. This advanced automatic transmission is available with both the 1.6 SIDI Turbo petrol engine and the 2.0 turbo diesel.

TECHNOLOGY
The Vauxhall Cascada brings together all Vauxhall's latest, innovative technology as part of the UK offer. This includes options like: AFL+ (Adaptive Forward Lighting) with up to 11 automatic lighting functions; Front Camera System, including Traffic Sign Recognition, Lane Departure Warning, Following Distance Indication and Forward Collision Alert; rear-view camera; heated steering wheel; Hill Start Assist; Side Blind Spot Alert.

Using an extremely rigid passenger cell made mainly from high-strength steel, the Cascada is designed for the least deformation and largest possible survival space in the event of a crash. Its doors have diagonally-mounted ultra-high strength steel beams and beltline reinforcements. The A-pillars supporting the windscreen are made from press-hardened steel. And in the event of a roll-over incident, pyrotechnically activated, spring-loaded high strength bars automatically deploy behind the rear seats. These pop-ups are also triggered during other severe impacts, eg. when airbags are deployed. Front seats both benefit from two-way active headrests and double seat belt pre-tensioners; even the two rear seats benefit from seat belt pre-tensioners.

With its German rivals firmly in its sights, the Cascada offers affordability paired with outstanding levels of equipment, technology and luxury.

Adaptive Forward Lighting
AFL is optional across the Cascada range at a cost of £790, and incorporates dark-style bi-xenon lights, LED daytime running lights and high-pressure headlamp washers. It offers drivers eight unique light settings which are selected automatically depending on road and weather conditions:
    Static Cornering: Throws light 90 degrees left or right for enhanced lateral vision
    Dynamic Curve Light: Activated by steering angle and speed, allowing lights to swivel by up to 15 degrees
    High Beam Assist: Automatically dips or raises headlight beam according to presence of oncoming traffic
    Adverse Weather Light: Wiper or rain sensor activated for better vision in bad weather conditions.
    Motorway Light: 140-metre range, higher and brighter than normal low beam
    Country Road Light: Wider spread and brighter light than normal low beam, with 70-metre range
    Town Light: Activated by road speed and street lighting, this has a lower and wider spread of light
    Pedestrian Area Light: Wider spread of light by up to eight degrees to left and right.

RANGE
The Cascada comes in two trims, SE and Elite. Range pricing starts from £23,995 and Elite pricing starting from £26,095.

The entry level SE gets 18" alloy wheels, a sports chassis, LED tail lamps and aux-in/USB, all as standard. The SE trim has the following standard spec:

Vauxhall Astra VXR, 2013

 

 

•  Vauxhall Astra VXR, 2013

The Vauxhall Astra VXR is a more extreme version of the GTC, and nothing embodies the visual changes more than the new model's exterior design revisions.

Adding extra presence, the Vauxhall Astra VXR gets a specially sculpted front and rear bumper, side skirts, aerodynamic roof spoiler and twin bumper-integrated tailpipes. Standard 19-inch wheels with 245/40 ZR tyres underpin the dramatic body, with 20-inch forged items available as an option for those customers who want to make their cars look even bolder.

The VXR shares much of its design with the GTC. Only three lines are used to create tension and define the outline of the silhouette. A fine, crisp line sweeps downwards from the front door to the bottom of the rear wing; a second line strikes through the door handle and stretches to the rear, emphasising the car's dramatic stance and broad shoulders. A third line follows the roof's clean, rakish silhouette.

The Interior
The centre-piece of the Vauxhall Astra VXR's cabin is Vauxhall's all-new flat bottom steering wheel. Its diameter has been reduced from 370mm to 360mm compared with all other models in the Astra range, making the steering feel even more precise and direct. The handwheel's grip has been enhanced by packing supple sponge rubber around a magnesium/steel hybrid ring and then covering the entire wheel in premium, soft cross-stitched leather. The wheel is available with an optional heated rim, and features the VXR logo, as well as multi-function controls on its spokes.

The other VXR-specific features abound, including a unique sports gearlever and alloy-plated pedals with rubber studs for better foot grip. Glossy piano-black chronograph-inspired dial rings contrast against a satin-black background, while the wing-shaped upper instrument cluster flows back into the doors and armrests. Black headlining, VXR-branded floor mats, and door panel stitching in Arden Blue or Cool Pearl give the Vauxhall Astra VXR's interior a purposeful yet exclusive feel.

A new design of front sports seat, made with cutting-edge lightweight material is standard across the Vauxhall Astra VXR range. Mounted 17mm lower than in the Astra GTC (and 30mm lower than in an Astra Hatch) the seats give front occupants a heightened sense of connection with the car's chassis.

Made from a strong but agile polyamide/fibreglass composite, the seat shells are formed using an organic injection-molded sheet which due to its strength only needs to be 2mm thick, and contributes to a 45 per cent weight saving compared with a seat using a conventional shell.

As standard, all Astra VXRs get manually adjustable front seats trimmed in half Black Track cloth and half Morrocana fabric. However, two option packs are also available. The VXR Performance Seat Pack (£495) adds full electric adjustment, heated seats, a manually extendable front seat cushion and lumbar/side-bolster adjustment as part of a package that includes a total of 18 different seat settings.

In addition, a Full Leather Pack (£1150) is available, comprising the multi-adjustable electric seat with a high-quality leather finish, embossed with the VXR logo. Two versions of the leather seats are available, each of which has a vertical leather stripe in the centre, picked out in either Arden Blue stitching or a gloss leather with Cool Pearl stitching (with matching door panel stitching). The VXR logo is embossed into the upper part of the front seats, while the seat itself is perforated to provide an air circulation function.

The CHASSIS
While the Vauxhall Astra VXR is based on the new GTC, it has benefitted from a raft of bespoke chassis modifications to cater for the significant boost in performance brought by the 2.0-litre turbocharged engine, which produces 280PS and 400Nm of torque.

With its dynamics developed by Vauxhall's engineering team, led by ex-DTM star Volker Strycek, the Vauxhall Astra VXR will target the very best rivals in class for handling, grip and overall driving excitement.

Setting it apart from all other current Astras is a specially developed mechanical limited slip differential, which works on the front wheels. In conjunction with the GTC's sophisticated HiPerStrut (High Performance Strut), the LSD provides the Vauxhall Astra VXR with exceptional lateral grip and traction through the bends.

Further changes to the chassis include brakes developed by competition supplier, Brembo, standard fitment of Vauxhall's fully adaptive FlexRide damping system, uprated springs and new dampers developed between VXR and ZF Sachs.

Mechanical Limited Slip Differential developed with motorsport supplier
Drexler, who supply differentials to the motorsport industry, have worked with Vauxhall to develop a mechanical multi-plate limited slip differential for the Vauxhall Astra VXR.

The unit, derived from that used in the Corsa VXR Nürburgring Edition, creates a locking effect with a ramp angle of 45 degrees under acceleration and 90 degrees under deceleration. The locking effect improves traction when it's needed - such as under acceleration through bends or over changing cambers and surfaces - but the effect is relaxed off-throttle, when it's not required, making the steering more benign.

To cater for the improved traction brought by the LSD, the Vauxhall Astra VXR's Traction Control (TC) and Electronic Stability Control (ESP) systems have been re-tuned to ensure the best performance, even when the car is used on track or in wet conditions.

VXR and Brembo develop bespoke braking system

With cross-drilled and ventilated 355 x 32mm front discs, four-piston callipers and harder compound brake pads, Vauxhall and Brembo have co-developed a bespoke braking system to cater for the Vauxhall Astra VXR's 280PS performance.

Using 'floating discs', the brakes are made from two different materials, with a cast-iron rotor mounted on an aluminium disc bell. This helps combine the heat resistance from cast iron with the light-weight properties of aluminium.

The key advantages of the system are reduced heat build up during repeated braking, as well as an improvement in overall brake feel through the pedal. There has also been a significant weight saving compared with the system found in the GTC, with each front calliper weighing 5.1kgs (-2.8kgs) and each front disc weighing 4.2kgs less than on the standard coupe. This means a total reduction of 7kgs per front corner from the car's unsprung weight.

The brakes, as well as all other chassis elements, were tested on public roads and in the toughest of environments including the Nürburgring and Contidrom race tracks in Germany, as well as on ice and snow in Scandanavia, and in the searing Spanish heat at the Idiada test track.

Springs, dampers, roll bars and bushes all improved for greater performance

Compared with the 1.6-litre, turbocharged GTC model, the Vauxhall Astra VXR's springs have been stiffened by 30 per cent and the car lowered by 10mm at the front and rear, to allow more driver connection on road and track.

The Astra's clever compound crank/Watt's link rear suspension was also stiffened, as were suspension bushes all round to cope with the extra chassis loads. The front anti-roll bar's diameter increased by 5mm over the GTCs, again for added stiffness.

Working with motorsport manufacturer, ZF Sachs, Vauxhall developed bespoke damper settings for the Vauxhall Astra VXR, using larger diameter pistons to the GTC's. The suspension sub-frame also rests on special mounts, the elastic-kinematic nature of which improves steering agility and support even when subjected to extreme lateral forces through tight bends.

HiPerStruts improve steering feel and help reduce torque-steer

The Vauxhall Astra VXR is equipped with a version of Vauxhall's HiPerStrut, also found on all GTCs and the 325PS Insignia VXR.

By reducing camber change during cornering, the HiPerStruts improve grip, reduce torque-steer significantly and enhance steering precision, due to a shorter and more compact rotational axis. Each strut has a 44 per cent reduced kingpin inclination and a spindle length (or kingpin offset) reduced by 46 per cent. This in turn means less camber loss during cornering, and therefore more grip, while the shorter spindle quells torque-steer reactions.

Standard FlexRide provides drivers with ultimate control

Vauxhall's FlexRide adaptive damping system is standard on all Astra VXRs. Drivers have the choice of three separate chassis settings which can be selected at the push of a button. 'Standard' delivers all-round performance for a wide range of road driving, with 'Sport' stiffening the dampers for reduced roll and tighter body control.

'VXR' is FlexRide's most extreme mode. Not only does it enhance throttle responsiveness, and change the instrument backlighting from white to red, but it alters the dampers settings once again. A ramp-control sub-mode further stiffens the dampers, but ensures that the wheels are in contact with the road instantly after hitting a bump. This means the car has a soft landing even when the springs on the struts rebound on an uneven surface. Meanwhile, the roll control sub-mode reduces tilt further during cornering.

Three modes of ESP to suit road and track driving
The Vauxhall Astra VXR's ESP (stability control) system offers three different modes. In its default mode, optimum safety is prioritised for everyday road conditions. 'Competitive' mode raises the threshold at which the automatic systems intervene, though when it senses a dangerous situation it will stabilise the car via the braking system. Finally, in 'ESP-off' mode, activated by pressing the button down for five seconds, the ESP system can be completely deactivated.

Two choices of unique wheel designs
As standard, the Vauxhall Astra VXR is equipped with flow-formed 19-inch alloy wheels with Pirelli 245/40 ZR tyres front and rear. However, customers can also opt for state of the art forged alloy 20-inch wheels, which weigh just 1.86kgs - 14 per cent less than the 20-inch rims available on the GTC model. The forging process used to make the lightweight rim creates a tougher material, allowing less aluminium to be used in its construction, and therefore reducing weight.

Combined with the savings in weight brought about by the Brembo discs, opting for the 20-inch rims on the Vauxhall Astra VXR gives drivers a total unsprung weight saving of over 14.5kgs across the front axle.

POWERTRAIN
Vauxhall's new Astra VXR will incorporate deliver a class-leading 400Nm of torque, giving it a 0-60mph time of 5.9 seconds and robust mid-range performance.

The VXR's turbocharged, 2.0-litre direct-injection engine harks from the Insignia family, but while its aluminium block is similar, the VXR has a unique aluminium cylinder head and new turbocharger to liberate 280PS (up 40PS on the previous model) and over 200Nm per litre of torque - the highest specific output in its class.

Developing a high-torque engine for the Vauxhall Astra VXR was the key to unlocking the car's real-world, mid-range performance, rather than focusing on power alone. And with maximum torque produced on a broad plateau between 2450rpm and 5000rpm, VXR drivers will never want for instant acceleration.

An all-new, state-of-the-art intake system was developed to feed as much air into the turbocharger as possible. The turbocharger itself was also improved to take more charge-air pressure, which builds from as early as 1400rpm for linear and strong acceleration. The maximum charge pressure is now 1.5 bar - 25 per cent more than in the Insignia 2.0T.

Vauxhall Astra VXR drivers can also look forward to a soundtrack that has been carefully engineered to appeal to enthusiasts, both from inside and outside the car. Drivers will get the full effect in the mid-to high rev range, especially when they change up from third to fourth under full throttle.

But outright performance hasn't come at the expense of efficiency and durability. Like all recent VXR models, the Astra was subjected to prolonged testing at the Nüburgring's notorious Nordschleife for 10,000 kilometres under race conditions - the equivalent to around 110,000 road miles.

And while the Astra VXR can accelerate from 0-60mph in just 5.9 seconds and hit a maximum 155mph, standard Start/Stop technology has reduced fuel consumption by 14 per cent (compared with the previous model) to a combined 34.9mpg, and reduced emissions to 189g/km.

All-new engine air intake system
Vauxhall engineers developed a completely new air intake system to improve air flow dynamics, reduce pressure loss and boost the engine performance even further.

The size of the intake air duct was significantly increased, as was the air cleaner's volume, reducing intake noise and allowing a greater quantity of air to be processed. This helped improve fuel consumption to a combined 34.9mpg, while reducing emissions to 189g/km - a 12 and 14 percent drop respectively compared with the previous Astra VXR.

Toughened and more durable turbocharger for quick throttle response

The engine's turbocharger is based on the twin-scroll principle. This means that in the exhaust manifold and turbocharger, the channels of the first and fourth cylinders are separated from those on the second and third cylinders. The pulsating exhaust gases are fed through spirals (scrolls) and brought together directly ahead of the turbine. By separating the flows, their dynamics are fully exploited.

The build-up of pressure starts as early as around 1400rpm. The maximum charge pressure has been increased to 1.5 bar - that represents a 25 per cent increase compared with the one used in the 2.0T Insignia. It was therefore necessary to make the turbocharger even tougher, more durable and able to withstand the increase in pressure.

Further important features to this compact turbocharger include the pneumatic over-run air valve and an efficiency-optimised turbine wheel. At a defined vacuum, a valve is opened which leads the air back to the compressor inlet. This keeps the speed of the charger at a high level. When the accelerator pedal is pressed again, charge pressure is then immediately available. To increase volumetric efficiency in the combustion chambers, the pre-compressed air is cooled by around 100 degrees Celsius in an intercooler before entering the chambers.

Optimised exhaust system for even better performance

Engineers also focused on reducing exhaust back pressure as a way of improving engine performance. Both the closed-couple converter (the catalyst near the engine) and the under-floor converter were tuned to reduce exhaust back pressure. Along with increasing the bore of the entire exhaust system, Vauxhall's engineers achieved a 25 per cent overall reduction in exhaust back pressure, versus the system used in the Insignia 2.0T.

In line with the mechanical changes made to the intake, exhaust and turbocharger, elements of the engine control unit (ECU) governing charge air pressure, fuel injection rate and ignition were all re-tuned.

Sound engineering
For drivers of cars like the Vauxhall Astra VXR, the soundtrack when you accelerate is almost as important as the time it takes to reach 100mph. So needless to say, engineering the right type of engine noise was an important part of the car's development.

Using a recent amendment to European noise regulations on pass-by noise - also known as the Lex Ferrari rule - engineers were able to liberate 75 decibels for the Astra VXR, a full decibel louder than the Astra GTC 1.6T. In order to pass the Lex Ferrari test, the Vauxhall Astra VXR had to accelerate from 50kph to 61kph in third gear on a stretch of road measuring just 15 metres - normally a challenge for all but the most powerful cars.

With an underlying robustness in its character, the engine noise recreates the jet-like noise of its predecessor under mid to high revs, when heard from inside the cabin. And thanks to the removal of one of the GTC's three silencers, there's even a distinctive burble at idle.

The twin bumper-integrated tailpipes have parallelogram-shaped openings and are unique in this class.

Nordschleife - the ultimate proving ground!
Before the modified Astra VXR engine could go into production, it was subjected to a series of challenging tests, one of which was to circulate the Nordschleife segment of the Nürburgring at race speeds for 10,000 kilometers, roughly equal to 180,000 road miles.

To achieve this level of durability, the Vauxhall Astra VXR's engine incorporates some novel features. Its high thermal endurance is supported by a water jacket which extends to the bottom of the cylinders, as well as oil-spray cooling for the underside of the pistons. Both camshafts in the engine respond automatically to an electro-hydraulic cam phaser, matching the valve opening times to the engine load status via the engine control unit. In addition, a higher overlap at lower speeds with continuously variable camshaft phasing ensures the turbocharger responds more quickly. The outlet valves are sodium-filled and all valves are actuated via low friction roller valve levers.

Other engine features are two counter-rotating balance shafts, low-maintenance chain drive for the camshafts and a cast-on oil filter housing, which is easily accessible from above. An oil change simply requires replacing the cartridge and is signaled by an interval indicator. Sensors measure wear and tear of the fully synthetic lubricant according to parameters such as the number of cold starts, as well as the overall number of starts.

MARKET & RIVALS
Volker Strycek, head of VXR product development and a former DTM driver and Nürburgring 24-hour winner, makes it clear about what his team wanted to achieve with the all-new Astra VXR. "Our goal was quite simple: to be the best in segment."

And with the UK's 'hot-hatch' market brimming with fresh and exciting products, the new Astra VXR had to raise the bar still further. Key to its success was the sophistication of its powertrain and chassis. With 280PS, the VXR produces more power than any of its current rivals, allowing it to accelerate from 0-60mph in a class-leading 5.9 seconds. But the killer punch is its 400Nm of maximum torque, giving it the highest specific output in its class.

The new VXR's chassis will be equally competitive, with a mechanical limited-slip differential (unique in class as a standard item), HiPerStrut front suspension, and bespoke brakes, springs and damper settings.

As with the previous Vauxhall Astra VXR and the current GTC, the UK will be the new model's biggest market. Around 10 per cent of all GTC volume will be VXR, equalling about 1200 units per year - the highest of any VXR model.

Key rivals will come from Volkswagen and Renault in the form of the Scirocco R and Megane Sport 265 (as well as the Focus ST, when it arrives in the UK). But the Astra VXR's keen pricing - £26,995 on the road - will undercut the Scirocco's by nearly £4,000, and that of the Megane 265 by more than £2000 when the Renault's equipped with its optional Cup Pack, including 19-inch alloys and a limited-slip differential (both standard on the Vauxhall).

Other standard equipment on the Vauxhall Astra VXR includes FlexRide adaptive damping, DAB, USB, Bluetooth and LED tail lights.

Vauxhall's unique Lifetime Warranty will also provide first owners of the VXR with the reassurance of comprehensive cover for however long they own the car.

The UK's hot-hatch class has become significantly hotter in the seven years since Vauxhall launched the first Astra VXR. Back then, the class norm for power was between 200PS and 250PS (the first Astra VXR produced 240PS), whereas now it starts at around 230PS right up to the new VXR's 280PS.

VXR customers can choose from a wide range of optional extras, including full leather upholstery and electrically adjustable seats, satnav with SD card and aux-in and Intelligent Adaptive Forward Lighting. One of the most popular options will be the VXR Aero Pack, which Vauxhall expects 85 per cent of customers to choose. For just £995, it includes 20-inch alloy wheels, a BiPlane Rear Spoiler and extended side skirts.

VXR - one of the fastest growing automotive sub-brands

The VXR brand has gone from strength to strength since the first car - a VXR220 Turbo - went down the line in 2004.

Buoyed by the success of Vauxhall's BTCC programme, the VXR badge was soon applied to a wide range of models, from the V8-powered Monaros to the Corsa, Vectra, Zafira and even the humble Meriva. The original Astra VXR joined them in 2005 and instantly became the best-seller in the VXR range.

More recently, the range has been rationalised and now extends to just four models: the Corsa VXR/VXR Nürburgring, new Vauxhall Astra VXR, Insignia VXR and VXR8 family, including the VXR8 GTS, Maloo and Sports Tourer.

Vauxhall Adamm, 2013

 

 

 

 

•  Vauxhall Adamm, 2013

The Vauxhall released the first official pictures of the new Vauxhall ADAM, heralding a sea-change in the fashion-led A-sector with an urban chic car that can be personalised in over a million different ways.

Using premium materials and design cues often found in the luxury sector, Vauxhall ADAM is a three-door, four-seater that will be unveiled at the 2012 Paris Motorshow, before appearing in UK showrooms early in 2013.

Designed by Brit, Mark Adams' team in Europe, ADAM incorporates a 'floating' roof which is visually disconnected from the body, making the use of two-tone colour schemes more impactful than ever before.

Classy, sophisticated and glamorous, Vauxhall ADAM retains design signatures from other Vauxhalls: the crisp line around the door handle (GTC), the wing-shaped chrome grille bar (new Astra) and the blade shape in the lower doors. It will also be the first car in the A-sector to have the option of LED daytime running lights.

But unlike other rivals in the segment, Vauxhall ADAM bucks the trend for retro-based design with a fresh and bold look that will appeal to open-minded individuals who want to defy convention with a car that's distinctive and striking.

And it's those very customers that Vauxhall is targeting with Vauxhall ADAM's high degree of personalisation options. Available in three trims from launch - JAM (fashionable/colourful), GLAM (elegant/sophisticated) and SLAM (racy/sporty) - ADAM customers can effectively 'build' their own car.

There are almost unlimited visual combinations, with a wide variety of exterior colours - including two different roof colours - interior colours, equipment and materials. Customers can even choose their headlining, including an LED-lit starlight roof trim.

Powertrains
Vauxhall ADAM will be offered with a choice of three efficient ecoFLEX four-cylinder petrol engines from launch: a 1.2-litre 70PS, plus two 1.4-litre engines with either 87PS or 100PS. All will be available with optional Start/Stop technology and will be mated to a five-speed manual gearbox.

Later on, ADAM will be the first car in Vauxhall's range to adopt the new-generation small petrol engine, featuring direct injection and forced induction, and an all-new six-speed gearbox.

Unique to the A-segment is Vauxhall ADAM's new top-of-the-range infotainment system designed to support new media sources, including Bluetooth, as well as connectivity for smartphones with Android or Apple iOS software. This enables access to internet-based applications, including GPS navigation. The system uses a state-of-the-art seven-inch, full-colour touch screen display allowing quick access to a variety of on-board controls.

Round, mechanical clock-style instruments with chrome bezels mark a departure from those seen in other Vauxhalls, while ADAM customers can also opt for a heated steering wheel - another first in the class.

Advanced technology enhances safety and comfort
Vauxhall ADAM will break new ground in the A-segment, by offering technology normally only found in higher-end cars.

A prime example is the Advanced Park Assist II system, which will be an ADAM option never seen before in a Vauxhall production car. Drivers engage the system with a button on the dashboard and it tells them when they reach a parking space large enough to accommodate the car. The system then automatically steers them into the parking space, with the driver only needing to control the brake, clutch and gears. APA II uses ultrasonic sensors to work its magic, and always comes in combination with Side Blind Spot Alert (SBSA).

As with all Vauxhall's, ADAM uses the very latest safety technology. High-strength steel is used to make an ultra-rigid passenger cell. This is complemented by front, side and head curtain airbags, as well as dual seat belt pre-tensioners for front occupants which offer additional knee and leg protection. Other safety features include two sets of ISOFIX points to easily and safely attach child seats on the 50:50 split foldable rear bench.

Crisp ride and handling; ESP standard across range
Despite its compact dimensions of nearly 3.7 metres in length and 1.72 metres in width, Vauxhall ADAM's footprint is relatively broad, with front and rear tracks of 1485 and 1478mm respectively, and a wheelbase of 2311mm.

Front suspension is by MacPherson strut, with a compound crank system at the rear. Wheel sizes range from 16- to 18-inch, and cars that are specified with 17- or 18-inch rims come as standard with the lowered sports chassis. The latest generation ESP system is standard on all ADAMs, including a Hill Start Assist function.

Handling on urban roads is enhanced by a CITY mode, which increases the electronic power steering system's assistance at lower speeds.

Ordering/first deliveries
Vauxhall ADAM will be available to order after its official premiere at the 2012 Paris Motor Show in September, with the first cars reaching UK customers in January 2013. As with all Vauxhalls, ADAM comes with Lifetime Warranty, which covers first owners for the lifetime of the car, or up to 100,000 miles.
