Dismal, especially considering the interior capacity of the vehicle. see full Land Rover Discovery review

What IS there to like about 16 mpg using $3.30/gal premium fuel? see full Land Rover Discovery review
2000 4dr SUV 188-horsepower 4.0L V8
4-speed automatic AWD w/low range
Well its terrible, I get 11-13miles, maybe a little more on the highway with cruise control and minimal braking. Absolutely terrible. Worse than a hummer. Better at offroading than a hummer though! see full Land Rover Discovery review

Awful! Big V-8 gets approximately 14 mpg, if I'm lucky! see full Mercedes-Benz SL review

Not great. I averaged about 16mpg in around town driving, about 22 on the freeways. Best mileage observed was in Wyoming, 24.5, coming downhill eastbound from the Grand Tetons. that said, people shouldn't buy this car expecting a Miata, in any way other than Two Doors and a Convertible Top. see full Mercedes-Benz SL review
