Jeep Grand Cherokee
New for the 2009 model year, Jeep Grand Cherokee features a new 5.7-liter HEMI®, which provides better fuel economy, improved idle quality and overall refinement.
With 357 horsepower (266 kW) and 389 lb.-ft. (527 N•m) of torque, this new HEMI engine also delivers an 8.2 percent increase in horsepower and a 3.7 percent increase in torque compared with the previous generation engine.
2009 Jeep Grand Cherokee customers also will benefit from the HEMI engine’s fuel-saving Multi-displacement System (MDS), which seamlessly shifts to smooth, high-fuel-economy four-cylinder mode when less power is needed, and back to V-8 mode when more power is in demand. The MDS system optimizes fuel economy when V-8 power is not required, without sacrificing vehicle performance or capability.
The 3.0-liter common rail turbodiesel (CRD) engine produces 215 horsepower (160 kW) @ 3,800 rpm and 376 lb.-ft. of torque (508 N•m) @ 1,600 rpm. The engine offers up to 30 percent improvement in fuel economy compared with traditional gasoline engines, and reduces CO2 emissions by an average of 30 percent. Jeep Grand Cherokee vehicles equipped with the available 3.0-liter CRD will be built until the end of the 2008 calendar year.
The 3.7-liter V-6 engine provides the 2009 Jeep Grand Cherokee with a powerful standard engine that delivers efficiency, durability and smooth operation. It produces 210 horsepower (157 kW) @ 5,200 rpm and 235 lb.-ft. (319 N•m) of torque @ 4,000 rpm. The Jeep Grand Cherokee’s available Flexible-fuel Vehicle (FFV) 4.7-liter V-8 engine offers better fuel economy, power and torque than the previous generation 4.7-liter high-output engine. The result is 305 horsepower (227 kW) @ 5,650 rpm, a 30 percent increase, and 334 lb.-ft. (453 N•m) of torque @ 3,950 rpm.
