The Jeep® Commander is the first Jeep vehicle with three rows of seats allowing for more passengers – seven total – to visit more places and enjoy its go-anywhere, do-anything capability.
The 3.7-liter engine provides the 2008 Jeep Commander with a powerful standard single-overhead-cam (SOHC) engine that is efficient, durable and smooth. It produces 210 hp (157 kW) @ 5,200 rpm and 235 lb.-ft. (319 N•m) @ 4,000 rpm. A sophisticated Electronic Throttle Control (ETC) system tailors throttle response to pedal movement based on operating conditions, and maintains a consistent vehicle speed on rolling grades when cruise control is active.
All-new for 2008, the 4.7-liter V-8 incorporates two spark plugs per cylinder (the only Chrysler LLC engine to do so, other than the 5.7-liter HEMI®), increased compression ratio, improved cylinder-head port flow and a new combustion system. The result is 305 horsepower (227 kW) @ 5,650 rpm, a 30 percent increase, and 334 lb-ft (435 N•m) of torque @ 3,950 rpm, a 10 percent increase and more than five percent increase in fuel economy compared with the previous 4.7-liter V-8 engine. And, like the engine it replaces, the new 4.7-liter V-8 engine is flex-fuel capable, which gives customers the ability to use up to an 85 percent concentration of ethanol (E85) to fuel their vehicles.
The 5.7-liter HEMI with the Multi-Displacement System (MDS) gives Commander best-in-class performance. MDS imperceptibly deactivates half the cylinders of the 5.7-liter HEMI during cruising and light acceleration to increase fuel economy up to 20 percent, depending on driving conditions. A sophisticated ETC system tailors throttle response to pedal movement based on operating conditions, and maintains a more consistent vehicle speed on rolling grades when cruise control is active, compared with the former mechanical throttle control system. The HEMI produces 330 hp (246 kW) @ 5,000 rpm and 375 lb.-ft. (508 N•m) @ 4,000 rpm.
