DrivetrainThe 2011 Jeep Grand Cherokee's standard engine is an all-new flexible fuel 3.6-liter V-6 engine. The 3.6-liter V-6 engine is an all-new design featuring double overhead camshafts (DOHC) and a high-pressure die-cast aluminum cylinder block in a 60-degree configuration. It features Variable-Valve Timing (VVT) and delivers 280 horsepower and 260 lb.-ft. of torque @ 4,800 rpm. This all-new V-6 engine increaes fuel economy up to 11 percent compared to the previous generation Grand Cherokee equipped with a V-6. It is coupled with the proven W5A580, a five-speed automatic transmission that delivers smooth shifts and

optimum fuel economy. The five-speed W5A580 transmission includes adaptive electronic control or Electronic Range Select (ERS) driver-interactive manual control and an electronically modulated torque converter clutch.The all-new 2011 Jeep Grand Cherokee's larger fuel tank, with a 24.6 gallon capacity, combined with the V-6 engine's improved fuel economy, delivers a range of approximately 500 miles on one tank of gas, which is pretty impressive for the size of this vehicle.
The available legendary 5.7-liter HEMI® V-8 engine delivers 360 horsepower and 390 lb.-ft. of torque @ 4,250 rpm. The HEMI is equipped with Variable Valve Timing (VVT), which delivers performance and towing capability, as well as fuel efficiency with the fuel-saving Multi-displacement System (MDS). The 5.7-liter HEMI V-8 engine is mated to the 545RFE multi-speed automatic transmission. The all-new Jeep Grand Cherokee offers unbeatable trailer tow capability of up to 7,400 lbs. on 4x2 models when outfitted with the HEMI V-8 engine.
Versatile 4X4 SystemsThe 2011 Jeep Grand Cherokee has three available 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 operate. The system provides smooth operation over many of road conditions. This light-weight single-speed case is both proven, durable and highly 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 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 directed to the axle with the most traction. Quadra Drive II, with a rear Electronic Limited-Slip Differential (ELSD), delivers industry-leading traction capability. The system instantly detects tire slip and smoothly distributes engine torque to tires with traction. In some instances, 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.
