In the case of the 2009 Jeep Commander, its sure-footed nature is further enhanced with engine options that are each capable in their own mrights. Just as the name Jeep echoes capability through the canyons and valleys of the world, HEMI has become nothing short of a synonym for performance on the boulevards, highways and well-traveled avenues. Today, the 5.7L HEMI V8 with MDS has evolved into the most modern of efficient performers, and Commander serves as its showcase. Today you can craft an economical performance(1) from one of the mightiest engines available worldwide. Traveling on the highway, the HEMI engine’s 357 hp
and 389 lb-ft of torque jet you into passing and merging mode with ease. Maintain your cruising speed and the engine’s Multi-Displacement System (MDS) kicks in, deactivating four of the engine’s eight cylinders, boosting fuel efficiency. But when
you bury the pedal, the HEMI seamlessly springs back, running on all eight hemispherical combustion chambers in less than 40 milliseconds.
Variable Valve Timing (VVT) technology helps the HEMI achieve optimal efficiency at all times. With Commander, the additional available engines are stars in their own right. The available 4.7L V8 engine is a flexible-fuel workhorse that can run on gas or ecologically friendly E85, a fuel that’s an 85 percent concentration of ethanol. Fill your tank with either gas or E85 and you’ll still command 305 hp and 334 lb-ft of torque. The available 3.7L V6 engine is an efficient,(2) durable and strong performer that operates smoothly and quietly, an economical choice that’s proven to serve well. Commander leads off with a selection of impressive available powertrains and wraps up with one of the smoothest on-road rides available in any SUV. A supporting cast includes power-assisted variable-ratio rack-and-pinion steering that’s teamed with a world-class independent front and rear suspension system….. POWERTRAIN

VVT offers increased engine breathing throughout the rpm range by varying the degree that the valves open and close in conjunction with piston position. Results are tangible: better performance, more efficient operation and increased torque for towing and hauling. Multi-Displacement System (MDS) Deactivates 4 cylinders (1, 4, 6, and 7) during steady speeds between 40-60
mph, low acceleration and shallow-grade climbing conditions. Fuel economy is improved up to 6 percent, depending on driving habits(1) (5.7L HEMI V8) Transmission 5-speed automatic with Electronic Range Select, Tow/Haul feature, adaptive electronic control, Brake-Park Interlock and electronically modulated torque converter (3.7L)
