Powertrain
Among all of the many new 2014 Jeep® Grand Cherokee features, two in particular contribute to vastly improved fuel economy and driving performance: a new, clean, 3.0-liter Eco Diesel V-6 engine and a new eight-speed automatic transmission.
The result: Jeep has taken the most awarded SUV in history and raised the benchmark even further, achieving fuel economy up to 30 miles per gallon (mpg) in Eco Diesel form, and improved fuel economy, drivability and overall performance across the Grand Cherokee lineup.
Jeep Grand Cherokee's new 3.0-liter Eco Diesel V-6 engine is expected to achieve 30 mpg highway with a driving range of more than 730 miles. The award-winning Pentastar V-6 engine delivers 25 mpg, with a best-in-class range of more than 600 miles. And the legendary 5.7-liter V-8's fuel economy improves 5 percent, now achieving 21 mpg.
All-new clean 3.0-liter Eco Diesel V-6 engine
Enthusiasts in North America have been clamoring for a diesel-powered Grand Cherokee and Jeep has delivered. Producing a class-leading 240 horsepower and massive 420 lb.-ft. of torque, the 3.0-liter Eco Diesel is capable of towing 7,400 pounds - more than any competitor's V-8 equipped SUVs. With a 30-percent increase in fuel economy and a 56-percent increase in torque versus the Pentastar V-6 engine, the Eco Diesel achieves 21 mpg in the city and 30 mpg on the highway in 4x2 models. This allows for a best-in-class driving range of more 730 miles. Full-time 4x4 models have fuel economy figures of 20 city and 28 highway.
The new, 50-state legal, clean 3.0-liter Eco Diesel engine produces low CO2 emissions. MultiJet II common-rail injection and Selective Catalyst Reduction (SCR) help this new engine achieve these results.
The 24-valve, dual-overhead-cam engine features a block and bed plate crafted from strong compacted graphite iron (CGI), which contributes to stiffness without penalizing performance.
The clean 3.0-liter Eco Diesel's 60-degree cylinder banks enable more efficient packaging, while effectively balancing the potent inertia generated by torque-rich diesels.
Driver and passengers alike can expect a smooth, quiet ride on any journey. The new engine's 1-4-2-5-3-6 firing order helps manage rotation so neatly it needs no balance shaft to deliver the level of refinement for which the Grand Cherokee is known.
Further contributing to quieter performance, as well as optimal fuel economy and emissions reduction, is the clean diesel's common-rail fuel-injection system. Its 29,000-psi (2,000-bar) pressure is unmatched by any solenoid-based system.
Swirl-control intake ports benefit from a variable-geometry turbocharger and inter cooler that ensure the required engine response, whether merging on-road or surging off-road.
Temperature extremes are also addressed. The new engine's turbo is water-cooled to handle searing heat, while low-voltage ceramic glow plugs accommodate quicker cold-weather starts.
Other key features and benefits:
Finger-follower actuated valves with hydraulic adjusters
Chain-driven camshafts
Piston-cooling oil jets
Water-cooled exhaust-gas recirculation (EGR) for Tier II, Bin 5 and ULEV II compliance
B5 biofuel compatibility
50-state emission compliance
All-new eight-speed transmission
All three Jeep Grand Cherokee engines are now attached to Chrysler Group's new eight-speed automatic transmission, which provides better fuel economy, quicker acceleration and smoother shifting. Another benefit is a lower crawl ratio of 44.1:1 to aid in climbing over - or through - tough obstacles when equipped with a two-speed transfer case. This is a 46 percent improvement over the previous model's crawl ratio.
Robust enough to accommodate the Grand Cherokee Eco Diesel's prodigious torque, the new-for-2014 gearbox delivers not only the promise of durability, but its precise shift schedule enhances ride quality to luxury-car levels.
Fully electronic, the eight-speed automatic features on-the-fly shift map changing, with manual shifting capability and Electronic Range Select using steering-wheel paddle controls. More than 40 individual shift maps for specific conditions optimize shift quality and shift points for fuel economy, performance and drivability. The intelligent software takes into account variables including engine torque gradients, kick-down events, longitudinal and lateral acceleration, grade changes, friction detection and downshift detection to determine the appropriate shift map. Additional parameters integrated into the control strategy include vehicle speed control, electronic stability control interaction and temperature. The result is automatic shifting ideally attuned to the performance requirements of almost any driving demand.
The transmission efficiency and wide ratio spread provide the best possible fuel economy by operating at a lower engine rpm in both city and highway environments. The addition of more gear ratios also helps reduce the gaps normally associated with upshifting and downshifting.
Gear changes are nearly imperceptible due to the evenly spaced gear steps between each gear ratio. Internally, the transmission has four gear sets and five shift elements (multi-disc clutches and brakes). Only two shift elements are open at any time. With fewer open shift elements, drag losses due to multiple parts rotating relative to one another are reduced, improving fuel efficiency.
Award-winning 3.6-liter Pentastar V-6 engine
Twice named one of Ward's 10 Best Engines, Grand Cherokee's standard 3.6-liter Pentastar V-6 engine boasts 25 mpg on the highway for 2014 - a 9 percent jump from the prior model year.
The standard flex-fuel 3.6-liter Pentastar V-6 engine generates 290 horsepower and 260 lb.-ft. of torque. Combined with the new eight-speed transmission, Pentastar-equipped Grand Cherokees are now able to tow 6,200 pounds, a 24 percent increase over the previous year. The transmission also helps the V-6 models to achieve 17 mpg city and 25 mpg highway on 4x2 and 4x4 models. This allows the Grand Cherokee to have best-in-class driving range of more than 600 miles for gasoline-powered SUVs.
Grand Cherokee's 3.6-liter V-6 engine features a double-overhead cam (DOHC) and high-flow intake and exhaust ports, which in combination with variable valve timing (VVT) via dual independent cam phasing, allow optimum volumetric and combustion efficiency over the full speed and load range. This results in an exceptional, flat torque curve along with high specific power. The engine's torque exceeds 90 percent of its peak value from 1,600 to 6,400 rpm, which provides customers outstanding drivability and responsiveness.
Structural, intake and exhaust areas of the 3.6-liter V-6 engine are designed to deliver low levels of overall noise and achieve specific sound quality goals that meet discerning customer requirements.
An environmentally friendly oil filter system with optional integrated oil cooler is used to help protect the environment via incineration of the filter element. The use of long-life spark plugs and a high-energy coil-on-plug ignition system also helps reduce cost of ownership.
Celebrated 5.7-liter V-8 engine
Fuel economy improvements are not exclusive to Jeep Grand Cherokee's V-6 powertrains. The 5.7-liter V-8 engine produces 360 horsepower and 390 lb.- ft. of torque, and boasts best-in-class towing capacity of 7,400 pounds. Now mated to the new eight-speed transmission, and owing in part to VVT and Chrysler Group's seamless Fuel Saver cylinder-deactivation technology, the V-8 models now offer improved fuel economy of 15 mpg city and 21 mpg while 4x4-equipped models get a bump to 14 mpg city and 21 mpg highway.
The 5.7-liter engine's VVT improves fuel economy in two ways. First, it reduces the engine's pumping work by closing the intake valve later. Second, it increases the expansion process of the combustion event. This allows more work to be transferred to the crankshaft instead of being rejected out of the exhaust port as heat. VVT improves engine breathing, which further improves engine efficiency and power.
The 5.7-liter engine's Fuel Saver Technology with cylinder-deactivation seamlessly alternates between smooth, high-fuel-economy four-cylinder mode when less power is needed and V-8 mode when more power is in demand. This optimizes fuel economy when V-8 power is not required, without sacrificing vehicle performance or capability.
Eco Mode further improves fuel efficiency
The 2014 Jeep Grand Cherokee features a new Eco Mode that contributes to its improved fuel economy. Eco Mode optimizes the Grand Cherokee transmission's shift schedule and - in V-8 models - Fuel Saver Technology with cylinder deactivation as well as throttle sensitivity to maximize fuel economy. The Eco Mode also manages interactive deceleration fuel shut-off (IDFSO), which cuts fuel delivery when the vehicle is coasting to reduce fuel consumption.
In addition, the Eco Mode activates the vehicle's air suspension system (if so equipped), lowering the Jeep Grand Cherokee to "Aero Ride Height" earlier to improve fuel economy.
Eco Mode is automatically engaged upon vehicle startup. A button on the center stack allows driver's to disengage Eco Mode if more spirited performance is desired.
The Engineering
Since its complete redesign for the 2011 model year, Jeep® Grand Cherokee has received numerous accolades for its premium on-road driving dynamics, given its exceptionally stiff body structure and front and rear independent suspension. Combining that luxurious on-road performance with Jeep's seemingly unending level of capability results in a driving experience that is unquestionably unmatched, on any road or trail.
Air suspension
The 2014 Jeep Grand Cherokee rises above the road and rocks with the rugged Quadra-Lift air suspension system. The Quadra-Lift system features five height settings for optimum ride performance:
- Normal Ride Height (NRH): 8.7 inches of clearance offers improved fuel economy as well as improved aerodynamics during on-road driving
- Off-road 1: Lifts the vehicle an additional 1.3 inches from NRH for added height in clearing obstacles (10.0 inches)
- Off-road 2: Delivers legendary Jeep off-road capability and provides an additional 2.6 inches from NRH for 11.3 inches of ground clearance
- Park Mode: Lowers the vehicle 1.6 inches from NRH for easy ingress/egress. NRH and Park Mode are driver selectable allowing the driver full control over vehicle ride height
- Aero Mode: Lowers the vehicle 0.6 inches from NRH. Aero Mode is controlled by vehicle speed and adjusts for optimal performance and fuel economy. The vehicle will also lower to Aero Mode when in Sport Mode.
When the vehicle is operating in Eco Mode, it lowers itself to Aero Mode when vehicle speeds are between 52 mph and 56 mph for 20 seconds, or exceeds 56 mph, further enhancing Jeep Grand Cherokees aerodynamics for optimum efficiency.
Quadra-Lift adds up to 4.2-inches of lift span supported by four-corner air springs that provide a cushioned, premium ride. Quadra-Lift operates automatically, or may be controlled manually with console controls.
With the front air dam removed and the available Quadra-Lift air suspension, the 2014 Jeep Grand Cherokee features a 35.8-degree approach angle, a 29.6-degree departure angle and 23.5-degree breakover angle.
The 2014 Jeep Grand Cherokee is also available with load-leveling shocks. When payload is added to the vehicle, the shock's gas pressure increases until the vehicle reaches NRH.
Advantages to load-leveling shocks include improved load handling and trailer-tow performance. Load-leveling shocks are available with trailer-tow packages that do not already have the Quadra-Lift air suspension.
Selec-Terrain
In addition to the Quadra-Lift air suspension, the Grand Cherokee's Selec-Terrain traction control system allows customers to choose the on- and off-road setting for optimum performance. This feature electronically coordinates up to 12 different powertrain, braking and suspension systems, including throttle control, transmission shift, transfer case, Hill-descent Control and Selec-Speed Control.
The Selec-Terrain system has been refined for 2014 and offers five different driving conditions to achieve the best driving experience on all terrains:
- Sand: Traction control and Quadra-Lift operate with sensitive response to wheel spin, and torque tuned for optimal performance in sand
- Mud: Traction control and Quadra-Lift operate with sensitive response to wheel spin, and torque tuned for optimal performance in mud
- Auto: Automatically adapts to any on- or off-road situation
- Snow: Vehicle traction adjust for ultimate performance over snow-covered roads
- Rock: Quadra-Lift suspension raises to maximum height of 11.3 inches, while the transfer case, differentials, and throttle coordinate to provide low-speed control
Sport Mode, previously found on the Selec-Terrain controller, is now engaged with the shift lever. Sport Mode provides enhanced on-road "fun-to-drive" capability.
Selec-Terrain, coupled with the Quadra-Lift air suspension, offers drivers an adjustable suspension span that delivers Trail Rated performance.
Go Anywhere 4x4 Systems
The 2014 Jeep Grand Cherokee features three 4x4 systems - Quadra-Trac I, Quadra-Trac II and Quadra-Drive II.
Quadra-Trac I delivers full-time four-wheel drive without any switches or levers to pull. The system provides smooth operation of the vehicle over a variety of road conditions. This lightweight single-speed transfer case is both proven and efficient for enhanced fuel economy.
Quadra-Trac II's two-speed transfer case uses input from a variety of sensors to determine tire slip at the earliest possible moment and takes corrective action. The system also uses Throttle Anticipate to sense quick movement in the throttle from a stop and maximizes traction before tire slippage occurs. When wheel slippage is detected, as much as 100 percent of available torque is instantly routed to the axle with the most traction.
Quadra-Drive II, with a rear Electronic Limited-slip Differential (ELSD), delivers industry-leading tractive capability. The system instantly detects tire slip and smoothly distributes engine torque to tires with traction. In some cases, the vehicle will anticipate low traction and adjust in order to proactively limit or eliminate slip.
Selec-Terrain is standard with Quadra-Trac II and Quadra-Drive II.
Trail Rated
All 2014 Jeep Grand Cherokees equipped with the Off-road groups are Trail Rated. The Jeep Trail Rated badge on the 2014 Jeep Grand Cherokee indicates that the vehicle is designed to perform in a variety of challenging off-road conditions identified by five key consumer-oriented performance categories: traction, ground clearance, maneuverability, articulation and water fording.
The 2014 Jeep Grand Cherokee is an increased crawl ratio of 44.1:1 compared to 30.2:1 (3.6-liter V-6) of the previous generation, a 46 percent improvement.
Jeep Trail Rated is a unique methodology used by Jeep Engineering to measure and predict off-road performance for all Jeep vehicles. Through a combination of natural and controlled field tests, Jeep Trail Rated provides a consistent measurement of off-road performance for all Jeep vehicles. Only Jeep vehicles are Trail Rated.
Selec-Speed Control
Jeep Grand Cherokee offers a new, important capability feature for 2014. Selec-Speed Control features both Hill-descent Control - and brand new Hill-ascent Control. This allows the Grand Cherokee to climb and descend steep grades with minimal driver input.
On-road refinement
Jeep Grand Cherokee is widely known for its outstanding on-road driving dynamics, thanks in part to its front and rear independent suspension. Variable-rate rear springs deliver improved on-road handling and comfort that complements the vehicle's off-road capability. Premium on-road manners are enhanced with more than 5,400 welds in the body alone.
The independent front and rear suspension features isolated front and rear suspension cradles along with variable-rate rear springs to deliver improved on-road handling and comfort while complementing the vehicle's legendary off-road capability. The rear suspension also allows the spare tire to be stored inside the vehicle as opposed to underneath.
Grand Cherokee's steering has also been carefully calibrated for the right amount of assistance whether cruising the parking lot or a twisty two-lane mountain road. Electrohydraulic assistance is used on EcoDiesel and Pentastar V-6 models.
Design
When the current-generation Jeep® Grand Cherokee made its debut, it impressed consumers with its cohesive, upscale design that was still able to convey the rugged capability expected in a Jeep vehicle. For 2014, Grand Cherokee takes its successful recipe to a new level of opulence and strength in both exterior and interior design.
All trim levels of the 2014 Jeep Grand Cherokee have been given a more premium look, and are more readily identifiable at a quick glance. On all Grand Cherokee models, the upper grille is shorter in height and the headlamps are slimmer. The lower front fascia has been slightly elevated and the fog lights have been raised and are more pronounced within the fascia design. Together, these changes give the front of the Grand Cherokee a more substantial appearance while still preserving the vehicle's ground clearance at its lower edge.
Of course, Grand Cherokee retains Jeep's classic seven-slot grille and trapezoidal wheel arches.
The rear of the 2014 Jeep Grand Cherokee features new, larger tail lamps with signature LED lighting, a larger rear spoiler to aid in efficient aerodynamics and a re-sculpted tailgate that offers greater rear visibility, and a more pronounced Jeep badge, now found directly on the tailgate between the tail lamps. Lower rear fascias are now model-specific, and dual exhaust tips are standard on all Limited, Overland and Summit models.
New premium LED lighting
A key exterior feature of the 2014 Jeep Grand Cherokee is its signature front and rear LED lighting. These unique lights allow Grand Cherokee to be instantly recognizable, night or day, from a great distance. Standard on Overland and Summit, and available on Limited, are new bi-xenon high-intensity discharge (HID) headlamps (adaptive on Summit) that are outlined with signature LED running lamps. The LEDs start at the inner upper edge at the grille, and follow the outer edge of the light. A slight kink upward occurs at the bottom edge of the LED lights as it nears the inner edge. This also allows for the Summit model's hidden headlamp washers to be placed within the headlamp housing as opposed to a separate nozzle located on the bumper.
The signature headlamps also feature full LED turn indicators.
The LED lights in the rear tail lamps follow the same pattern as the headlamps. A red ring of LED lamps follows the outline of the stop lights and illuminates when the headlamps are on. The lower portion of the tail lamp assembly is outlined in chrome and houses the reverse lights. The rear LED lighting features a dispersed pattern for a seamless lighting effect, unlike other LED systems where individual filaments can be seen.
Grand Cherokee open-air options
The 2014 Jeep Grand Cherokee features the CommandView dual-pane sunroof that extends from the windshield to the rear of the vehicle, allowing for perfect views both on- and off-road. CommandView is comprised of two glass panels with the front panel opening rearward providing additional light and fresh air to first-row passengers. The rear panel, which is fixed, allows light and open viewing for second-row passengers. The system comes standard with a power sun shade for those who may not want direct sunlight. CommandView is standard on Overland and Summit models and available on Limited.
A traditional sunroof is available on Laredo and Limited models.
Unique exterior styling for each Grand Cherokee model
Jeep Grand Cherokee Laredo models are identified by its body-color grille and chrome headlight treatment. Body-color side mirrors and door handles are also Laredo exclusives. All lower rocker trim is dark gray. Standard wheels are five-spoke 17-inch aluminum wheels painted Tech Silver. Available aluminum 18-inch wheels with a twin five-spoke design are painted Satin Silver. The rear fascia features the new signature tail lamp design along with dark gray lower trim and a single chrome exhaust outlet.
Grand Cherokee Limited models keep the dark gray lower rocker trim and add a body-color grille with chrome grille slot frames and headlight treatment. Bi-xenon headlamps with Grand Cherokee's signature LED running lights are available. Chrome trim outlines the lower fascia opening and skid plate. The wheels on Limited are aluminum 18-inch with a twin five-spoke design and are finished in Satin Chrome. Polished 20-inch five-spoke aluminum wheels with Mineral Gray-painted pockets are optional. The Limited's rear fascia features a chrome trimmed bumper sill protector and dual chrome exhaust outlets.
All Limited (and Overland and Summit) models feature standard chrome side mirrors and door handles.
Grand Cherokee Overland models feature bi-xenon HID headlamps with signature LED daytime running lights, chrome tow hooks in the lower fascia and body-color lower fascia trim. The body-color trim carries over to the wheel arches and surround the polished 20-inch five-spoke polished aluminum wheels with Mineral Gray-painted pockets. The lower rocker panels and trim on the rear fascia also become body color.
The new luxurious Grand Cherokee Summit model tops the range and receives many unique styling cues. The bi-xenon HID signature headlamps are adaptive, and swivel in conjunction with the steering wheel. This improves visibility around bends and turns and is a brand new safety feature for Grand Cherokee. High-pressure headlamp washers are standard.
