2008 Jeep Grand Cherokee Real Gas Mileage: Pros

2008 4dr SUV turbocharged 215hp 3.0L V6 Diesel
5-speed shiftable automatic AWD w/low range		 amazing on the highway. 9.5 l/100 km see full Jeep Grand Cherokee review
2007 4dr SUV 235-horsepower 4.7L V8
5-speed shiftable automatic AWD w/low range		 I am fortunate in that I work from home, and do not need my vehicle to commute to work. However, for a six month period I made a 40-mile round trip five days a week, and averaged 15MPG in mixed urban surface/Interstate driving. This is considerably better than the 2007 Jeep Grand Cherokee 4wd/4.7L V8 the truck replaced (13MPG), and I attribute the better performance to the MDS cylinder deactivation. I have observed 22MPG over a 400 mile trip of combined Interstate and rural 2-lane highway travel with speeds ranging from 60-75 MPH. The truck was unloaded at the time and acceleration runs were gentle to maximize fuel economy. The return trip resulted in19MPG performance over the same route. see full Jeep Grand Cherokee review

5-speed shiftable automatic AWD w/low range		 20mpg at 70 mph is adequate but not great. 14mpg average suburban city driving. see full Jeep Grand Cherokee review
2007 4dr SUV 235-horsepower 4.7L V8
5-speed shiftable automatic AWD w/low range		 Fuel economy is abysmal. The 4.7L V-8 engine, only moderately powerful, is far thirstier than the much more powerful 5.7L Hemi option owing to the Hemi's cylinder deactivation. Real-world fuel economy in city driving is 11-13MPG. On longer trips it can occasionally see 20MPG if speeds are kept below 70MPH. The 4.7L drivetrain is a compromise between the V-6 and the Hemi versions in terms of cost, with the added capability of being able to operate on E-85 fuel when properly equipped. You will undoubtedly want to go with the Hemi version instead of the 4.7L if you can afford it, the benefits are more than just the extra power. If you are familiar with the performance of the 4.7L in the older WJ models, prepare to be disappointed by the performance in the 2005-2010 WK models: they weigh 600 pounds more, and you can definitely feel the difference. Do not buy ANY Jeep Grand Cherokee if you are a budget-conscious big city commuter; you have to accept the fuel economy as the trade off for uncompromised traction in poor weather conditions. This machine has a "real" 4 wheel drive system: it's always on, it's always ready to step in when the going gets slippery, and provided the tires are good enough it will plow snow with its front bumper. A V-6 version only gets marginally better fuel economy but with a significant decrease in power. In truth, if you're worried about fuel economy, you should be looking at the car-based Jeep Compass or Patriot models, not the Grand Cherokee. see full Jeep Grand Cherokee review
