The 2012 Jeep® Grand Cherokee delivers with even more refinement and features that can be appreciated on the road and off. Since its introduction, the 2012 Jeep® Grand Cherokee has captured more than 30 awards from an array of opinion-leading organizations making it the most awarded SUV ever.
For the 2012 model year, Jeep Grand Cherokee receives enhancements that improve both on- and off-road performance. These changes, in combination with new option packaging, will keep Jeep Grand Cherokee at the head of the pack in terms of off-road ability, and on-road refinement.
Mechanical changes for the 2012 model year include a revised automatic transmission for V-8 models that allows for six speeds when shifted in manual mode, and an electro-hydraulic power steering system on V-6 models. Both new features allow for better performance and everyday drivability with improved efficiency.
Legendary 4x4 Capability
The combination of Grand Cherokee's Quadra-Lift® air suspension system and the Jeep Selec-Terrain® traction control system lets customers choose the 4x4 setting for the optimum experience on all terrains. Selec-Terrain 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).
The Jeep Selec-Terrain's control dial allows the driver to choose from five driving conditions in order to achieve the best 4x4 performance. Torque management to the drive wheels for maximum grip is achieved through the following settings:
The Jeep Grand Cherokee also offers the Quadra-Lift air suspension system, which features five height settings for optimum ride performance:
Front and rear independent suspension features isolated front and rear suspension cradles. Variable-rate rear springs deliver uncompromised on-road handling and comfort that complements the vehicle's off-road capability. The rear suspension allows the spare tire to be stored inside the vehicle.
Go Anywhere Jeep 4x4 Systems
The 2012 Jeep Grand Cherokee offers 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 over a variety of road conditions. This lightweight single-speed case is both proven and highly efficient for enhanced fuel economy.
Quadra-Trac II's two-speed transfer case actively manages torque and uses input from a variety of sensors in order to determine tire 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 maximizes traction before slippage occurs. When tire 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 with the ability to transfer up to 100% of available torque to one wheel.
Selec-Terrain is standard with Quadra-Trac II and Quadra-Drive II.
3.6-liter Pentastar V-6 Engine
The 2012 Jeep Grand Cherokee features the award-winning 3.6-liter Pentastar V-6 engine. This flexible-fuel 3.6-liter V-6 engine is standard and delivers 290 horsepower (216 kW) and 260 lb.-ft. (353 N-m) of torque at 4,800 rpm. Fuel economy has improved for both 4x2 and 4x4. 4x2 models have a rating of 17 miles per gallon city, 23 highway (up from 16/23) while 4x4 models achieve 16/23 (up from 16/22).
Jeep Grand Cherokee offers trailer-tow capability of up to 5,000 lbs. on models equipped with the Pentastar V-6 engine.
Legendary 5.7-liter V-8 Engine
The available legendary 5.7-liter MDS V-8 engine delivers 360 horsepower (268 kW) and 390 lb.-ft. (520 N-m) of torque at 4,250 rpm. The 5.7-liter V-8 also features VVT, which delivers performance and towing capability, and fuel efficiency with fuel-saving MDS. The MDS seamlessly alternates between smooth high-fuel-economy four-cylinder mode when less power is needed and V-8 mode when more power from the 5.7-liter MDS engine is requested. This optimizes fuel economy when V-8 power is not needed, without sacrificing vehicle performance. New for 2012, the 5.7-liter MDS V-8 engine is mated to the 65RFE automatic transmission that allows the driver to choose between six-speeds when shifted in manual mode.
All 4x4 models see improved fuel economy ratings of 13 miles per gallon city and 20 highway (up from 13/19). 4x2 models retain their 14/20 rating.
Trailer-tow capability of up to 7,400 lbs. is available with the 5.7-liter V-8 engine.
