Jeep Grand Cherokee Gas Mileage

The 2008 Jeep Grand Cherokee offers a diverse range of engines, with two choices that stand out for owners seeking the best possible gas mileage from their luxury SUV. The 2008 Grand Cherokee can be fitted with a torque-filled and highly-efficient common rail (CRD) turbo diesel Mercedes-Benz V-6 engine that’s well-suited to towing, along with a special Multi Displacement version of Chrysler’s legendary HEMI V-8 that’s been optimized for better gas mileage when cruising on the highway. The Multi Displacement Hemi is designed to deactivate 4 of 8 cylinders when the engine is not under load, providing a 20% boost in fuel economy.

For those with unapologetic lead feet (and little concern with mundane things like gas mileage), there’s the thrill-filled, chart-topping, HEMI-powered Grand Cherokee SRT8 (pictured above).

Here’s the complete rundown on the 2008 Jeep Grand Cherokee’s range of engine choices:

• 3.0 liter CRD turbo diesel V-6 producing 215 horsepower (HP) and 376 foot pounds of torque
• 3.7 liter V-6, producing 210 HP and 235 foot pounds of torque
• 4.7 liter V-8, producing 305 HP and 334 foot pounds of torque
• 5.7 liter Multi Displacement HEMI V-8 producing 330 HP and 375 foot pounds of torque
• 6.1 liter SRT HEMI V-8, producing 420 HP and 420 foot pounds of torque

The Mercedes-Benz turbo-diesel engine is an option in the Grand Cherokee Limited and Overland models. It is not available in CA, CT, MA, ME, NY, PA, RI, and VT.

Jeep Grand Cherokee Gas Mileage – 1993-2010

Note: the EPA tweaked their testing procedure, starting with the 2008 model year, with the end result being that the 2008 MPG estimates are now lower than previous years. As always, YMMV.
