Jeep Grand Cherokee UK Version, 2011
The new Jeep Grand Cherokee has been designed on a new platform to deliver premium on-road performance while maintaining the Jeep brand's legendary four-wheel drive, torque-on-demand two-speed transfer case for extraordinary off-road capability and durability.
The new vehicle offers significantly lowered emissions and improved fuel economy (up to 39 mpg) with its new turbocharged 3-litre V6 CRD engine, together with a world-class interior providing luxury, comfort and enhanced safety. Despite its rugged, trail-tested off-road capabilities, the new Jeep Grand Cherokee is a sophisticated, luxury SUV that can easily be driven on an everyday basis by anyone.
In the UK, new Jeep Grand Cherokee is available in two versions, Limited and Overland, both of which are powered by an all-new 237bhp 3-litre V6 turbodiesel.
The Exterior Design and Dimensions
The all-new Grand Cherokee features a muscular and athletic new look with a high waist line and a steeply raked windscreen. A low drag coefficient illustrates the efficient aerodynamic shape of the vehicle.
The contemporary design language is nevertheless unmistakably Jeep, and is instantly recognisable thanks to the classic trapezoidal wheel arches together with the familiar Jeep seven-slot grille.
In terms of dimensions, although the car is approximately 7cm wider and 7cm longer than the model it replaces, the wheelbase has been stretched by over 13cm to give extra boot space, and more specifically, extra rear leg-room.
With regard to the cargo area, new Jeep Grand Cherokee offers up to 782 litres of space with all the seats in place - 11% more than the previous model; and the tailgate is power operated on the Overland version. Notwithstanding the amount of luggage space available, a full size spare wheel is carried.
The new Jeep also features short front and rear overhangs for much improved approach, departure and breakover angles and consequent superior off-road capability. The front spoiler is removable for when the terrain gets really tough, giving an extra four degrees of approach angle.
The Interior Design
A world-class interior has been achieved thanks to fine materials and elegant appointments, while maintaining a focused attention to detail with high quality interior fit and finish throughout.
Premium materials such as real wood, leather, chrome accents, LED lighting, and premium seating deliver a strong impression of refinement and luxury - expressive design, quality of materials; the precise fit of all panels… these elements also contribute to enhanced noise isolation.
New, soft-touch materials are used at key 'touch points' throughout; including doors, consoles and armrests.
The quality of the seat upholstery is another important feature of the world-class interior. Both front seats are heated and ventilated with eight-way power assistance and four-way lumbar adjustment, with a memory system on the driver's side. In fact, the front seats feature an all-new structure with enhanced bolster contours for improved comfort. The moulded shape of the upper seat shoulder area adds to the look and feel of the seating, while the 12-degrees reclining rear seats, (60/40 split folding), together with the longer platform, enhance comfort for rear passengers who have over 100mm of additional rear legroom.
The Interior Equipment
Alpine Premium Sound System
The standard equipment Alpine Premium Audio System creates a full, realistic sound experience using a high-powered 12-channel, 506-watt amplifier powering nine speakers and a subwoofer. Optimally placed throughout Jeep Grand Cherokee's cabin, this surround-sound speaker system delivers an unparalleled aural experience. This premium audio system allows everyone onboard to hear music precisely as the artist intended it.
Media Centre
The Media Centre features an AM/FM radio, CD/DVD player, satellite navigation system (standard on Overland) that's controlled via a 6.5-inch touch-screen, and a 30GB hard drive. Owners can store up to 6700 tracks on the hard drive and upload music and photos through the USB port or from a CD/DVD. The system includes a single-disc CD player, and can also play DVDs when the vehicle is stationary and the transmission is in Park. Uconnect Bluetooth® with voice commands means that the sound system, sat nav and mobile phones can be operated hands-free.
iPod Interface
With the iPod Control, most iPod-compatible devices can be connected directly to the vehicle's audio system using the iPod control cable. The iPod can then be operated through the Media Centre sound system or via the steering wheel-mounted controls. While connected, the system even charges the iPod.
Keyless Enter-N-Go
As long as the vehicle's ignition keys are somewhere on the driver's person (maybe in a pocket or a bag) the vehicle picks up signals from the transponder and unlocks it, when the driver touches the door handle. It also activates the push-button starter: the driver just presses the brake pedal and pushes the button to start.
The vehicle's equipment can also be activated without starting the engine. Without a foot on the brake, the driver pushes the button once; pushes twice to turn on the heating/air conditioning and instrumentation; or three times to turn it off again.
CommandView panoramic sunroof (standard on Overland)
The front roof panel opens rearward, providing additional light and fresh air to front seat passengers. This front glass panel features an express one-touch open and close operation. The rear glass panel, which is fixed, provides extra light and visibility for rear seat passengers. A standard one-touch power sun-shade may be extended to cover the tinted glass panels when closed.
Platform
The all-new Jeep Grand Cherokee is the very first vehicle in the market to be built on this brand new platform. The structure was co-developed with Mercedes-Benz and will be used in next generation Mercedes vehicles. With an increase of 146% in overall torsional stiffness, it is now much stronger and more durable than before. As a result, noise, vibration and harshness levels have been drastically improved, giving much better on-road and off-road ride quality. The new platform engineering brings improvements in the following key areas:
- Manoeuvrability
- Overall agility
- Cornering ability
- Steering precision
The all-new Jeep Grand Cherokee tips the scale at 2,272kg, which is 38kg less than the outgoing model and represents a considerable achievement when the increase in dimensions is taken into account.
Outstanding touring attributes are another Jeep Grand Cherokee forte. The maximum towing capacity with a braked trailer is a class-topping 3,500kg, which includes an anti-sway damping system featuring a neutral position for flat towing.
Legendary 4x4 Capability
The all-new Jeep Grand Cherokee offers the new Quadra-Lift air suspension system, (standard equipment on Overland versions). Quadra-Lift air suspension system features five height settings for optimum ride performance:
- Normal Ride Height (NRH): 8.1 inches of clearance offers improved fuel economy and improved aerodynamics during on-road driving
- Off-road 1: Lifts the vehicle an additional 1.3 inches for added height in clearing obstacles (9.4 inches)
- Off-road 2: Delivers legendary Jeep off-road capability and provides an additional 2.6 inches of height for 10.7 inches of ground clearance
- Park Mode: Lowers the vehicle 1.5 inches from NRH for easy entry/exit and roof rack loading. NRH and Park mode are driver-selectable, giving the driver 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
Quadra-Lift adds up to 4.1 inches of lift span that is supported by four-corner air springs that provide a cushioned, premium ride. It operates automatically, or may be controlled manually via console controls. Quadra-Lift enhances the ride quality and takes the Jeep Grand Cherokee another leap forward. It's a first-class closed system with a stored air reservoir for a faster response and no lift-time deterioration.
Driver benefits are numerou:
- Ease of entry/exit for passengers
- Easier cargo loading and unloading
- Improved off-road capability by increasing ground clearance, approach, departure and breakover angles
- Improved on-road ride comfort
- Improved fuel economy at motorway speeds - automatically lowering vehicle height to reduce aerodynamic drag
In addition to the Quadra-Lift air suspension system, the all-new Selec-Terrain traction control system (standard equipment on both Limited and Overland), lets customers choose the appropriate off-road setting for the optimum experience on all terrains. This feature electronically coordinates up to 12 different powertrain, braking and suspension systems, including throttle control, transmission shift, transfer case, traction control and electronic stability control (ESC).
Selec-Terrain, coupled with the all-new Quadra-Lift air suspension system, offers drivers an adjustable suspension span that delivers world-class capability. The system's control dial allows the driver to choose from five driving conditions in order to achieve the best all-terrain driving experience.
- Sand/Mud: Traction control and Quadra-Lift operate with sensitive response to wheel spin, and torque is tuned for optimal performance
- Sport: Provides enhanced on-road fun-to-drive capability
- Auto: Automatically adapts to any on- or off-road situation
- Snow: Vehicle traction adjusts for ultimate performance over snow-covered roads
- Rock: Quadra-Lift air suspension system raises to maximum height (10.7 inches) and the transfer case, differentials, and throttle coordinate to provide low-speed control
With the front air dam removed, and the available Quadra-Lift air suspension system, the all-new Jeep Grand Cherokee features a 34.3-degree approach angle, (compared to 32.3 on previous model), a 29.3-degree departure angle (compared to 27.5 on previous model) and 23.1-degree breakover angle (compared to 20.4 on previous model).
The all-new front and rear independent suspension features isolated front and rear suspension cradles. Variable-rate rear springs deliver improved on-road handling and comfort that complement the vehicle's off-road capability. The new multilink rear suspension features lower control arms and camber/tension links that individually control cornering, bump and braking forces. This is regarded as the optimum set-up for ride comfort and handling stability. The compact design of the system also allows the spare tyre to be stored inside the vehicle as opposed to underneath. Anti-roll bars are features on both axles.
Go Anywhere 4x4 Systems
The 2011 Jeep Grand Cherokee employs a 4x4 system called Quadra-Trac II® which features a two-speed transfer box with low ratio gears and an electronically controlled clutch that allows variable torque distribution.
Quadra-Trac II's two-speed transfer case uses input from a variety of sensors in order to determine tyre slip at the earliest possible moment and take corrective action. The system uses Throttle Anticipate to sense quick movement in the throttle from a stop and maximises traction before slippage occurs. When tyre slippage is detected, as much as 100 percent of available torque is instantly routed to the axle with the most traction. Selec-Terrain is standard with Quadra-Trac II.
The drivetrain is further enhanced with sophisticated stability, hill assist and hill descent control systems featuring Brake Traction Control Systems on both axles (BTCS). BTCS uses the brakes to act on any wheel that is slipping, and allows additional torque transfer to those wheels with traction.
In addition, Hill Descent Control allows smooth and controlled descent on rough or slippery terrain without the driver having to touch the brake pedal. It applies the brakes to each wheel individually to slow the vehicle down and maintain driver control on steep slopes.
Meanwhile Hill Start Assist helps drivers make a hill start by keeping the brakes on for a short period of time after a driver's foot is removed from the brake pedal. If the throttle is applied when the driver's foot is removed from the brake pedal, the brakes are released.
