2011 JEEP Grand Cherokee in UK The new 2011 JEEP Grand Cherokee offers lower CO2 emissions and an improved fuel economy of just 39 mpg with the new 3 L turbo-charged V6 CRD engine. Mike Manley, President and Chief Executive Officer, :
"With the all-new 2011 Grand Cherokee, Jeep has created the benchmark, premium SUV Advanced features such as our new Quadra-Lift air suspension and Selec-Terrain traction control systems take the new Grand Cherokee to the next level of 4x4 capability. The new generation of the iconic Jeep Grand Cherokee delivers the perfect blend of on-road refinement, superb craftsmanship, world-class design, improved fuel economy, innovative features and legendary, real-world capability." Two models will be available in United Kingdom, Limited and Overland, both models powered by the same 3 L V6 turbo-diesel engine generation 237 horse power.

With all the seats in place, the new 2011 JEEP Grand Cherokee offers up to 782 L of space, with 11% mode than the previous model, being with 7 CM wider and 7 CM longer. Inside the 2011 JEEP Grand Cherokee, premium materials were used, materials like real wood, leather, chrome accents and LED lighting. Soft-touch materials are used at "touch points", including doors, consoles and armrests. A Alpine Premium Sound System is available, creating a full, realistic sound experience using 12-channel, 506 W amplifier, 9-speakers and 1 subwoofer. Besides the sound system, 2011 JEEP Grand Cherokee is equipped with a AM/FM radio, CD/DVD player, satellite navigation system controlled using a 6.4" touch-screen. Those who own a iPod-compatible device can connect it directly to the sound system.

The all-new 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 2011 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.

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 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 numerous, and include:

- 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.

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.

Engine

Jeep first showed the Euro 5-compliant V6 3.0-litre turbodiesel engine, available in the Grand Cherokee for the UK and Europe, at the 2011 Geneva Motor Show. The new CRD engine is more powerful, more fuel efficient and produces lower emissions than its predecessor.

Built by VM Motori and developed together with Fiat Powertrain Technologies, this new engine produces maximum horsepower of 177 kW (237bhp) at 4,000 rpm and torque of 550 Nm (406 lb-ft) at 1,800-2,800 rpm. This translates to 10 per cent more power and eight per cent more torque than the engine it replaces.

Even with its improved performance, fuel economy for the new 3.0-litre turbo diesel engine is 34.0 mpg (8.3 L/100km) on the combined cycle, an improvement of 19 per cent over the previous diesel engine. CO2 emissions (combined cycle) are also reduced by 20 per cent, now at 218 g/km.

From a retail perspective the improvement in CO2 emissions represents a saving of GBP1,220 in current VED taxation over a five year period compared with the outgoing model.

The V6 turbodiesel engine is fitted with new-generation, 1,800-bar injectors along with new MultiJet II technology, developed and patented by Fiat Powertrain, which made its debut in 2009 on the 1.3-litre diesel engine in the Fiat Punto Evo.

Engine Block Structure

The new engine features a compressed graphite iron, 60-degree block with aluminium cylinder heads and a two-piece structural aluminium oil pan. Bore is 83 mm (3.27 in) and stroke is 92 mm (3.62 in) for a total displacement of 2987 cc (182 in3). Bore spacing is 96 mm (3.78 in).

The engine is compact and lightweight, with overall dimensions of 695 mm (27.36 in) in length, 729 mm (28.7 in) in width and 697.5 mm (27.46 in) in height. Weight of the new engine, including ancillaries, is 230 kg (507 lbs).

The engine block features a notably stiffened crankcase construction, including a bedplate that provides a rigid and stiff carrier for the crankshaft. This in turn helps reduce overall noise from the lower reciprocating assembly and contributes to significant improvements in lowering overall noise, vibration and harshness.

Adding to the structural rigidity of the block, the two-piece aluminium oil pan has been designed to provide strength and contribute to the quietness of the engine. The lower pan has been reinforced for off-road use. Crankcase capacity is 7.7 litres.

Cylinder heads are constructed of aluminium and feature a chain-driven, dual overhead-camshaft design with four valves per cylinder. Intake valves measure 28 mm (1.1 in), and exhaust valves are 24.5 mm (0.96 in) in diameter. Combustion-chamber volume is 24.68 cm3 (1.51 in3).

A forged-steel crankshaft is supported by four main bearing journals fitted with four-bolt main bearing caps incorporated into the bedplate. Externally balanced, the crankshaft measures 442.2 mm (17.41 in), reducing the overall packaging requirements of the engine. Connecting rods, with an overall length of 162.9 mm (6.41 in), are constructed in cast iron.

Lightweight, cast-aluminium pistons are designed to provide minimal friction. The compression ratio of the new diesel engine is now 16.5:1, reduced from 18.1:1 on the previous model, contributing to cleaner combustion and providing more power.

All main bearings are a lead-free design for reduced environmental impact during construction and later recycling of the engine.

Engine Performance Features

The induction system includes swirl control to optimise combustion. Fitted between the intake system and the combustion chamber, swirl control effectively provides an ideal air/fuel mixture at all engine speeds.

Precise fuel delivery is through a 1,800-bar common-rail fuel injection system. Thanks to the new MultiJet II technology, which makes use of a special balanced solenoid valve, the new injector is capable of making up to eight injections per cycle with the possibility of managing the two main injections in a single modular profile (IRS – Injection Rate Shaping). This guarantees a reduction in consumption and polluting emissions of approximately 2% compared to a traditional injector and ensures a drastic reduction in noise levels.

The new 3.0-litre diesel engine utilises a single Garrett VGT 2056 turbocharger with variable turbine geometry. Compact and lightweight, the turbocharger provides near-instant response and includes an air-to-air intercooler.

Fuel Economy and Emissions

Fuel economy for the Jeep Grand Cherokee with the 3.0-litre turbodiesel engine is rated at 27.4 mpg on the urban cycle and 39.2 mpg on the extra-urban cycle. For the combined cycle, the fuel economy is rated at 34.0 mpg. At motorway cruising speeds, 700 miles can easily be achieved on a single tank of fuel. The engine is designed to run on EN590 ultra-low-sulphur diesel fuel.

For this power unit, cast-iron exhaust manifolds are utilised. Additional emissions controls include a close-coupled diesel oxidation catalyst and standard diesel particulate filter. Euro 5 emissions are met through an exhaust-gas recirculation (EGR) system that includes an EGR valve with DC motor and a high-performance EGR cooler with bypass valve.

Combined cycle CO2 emissions are now 218 g/km. Not only is the engine more frugal and environmentally-friendly, but it also delivers outstanding performance, providing the new Jeep Grand Cherokee with a 0-62mph time of 8.2 seconds and a top speed of 126mph.
