The GX has a 4.7l V8, but gets similar mileage to our old V6 powered Ridgeline, about 18 mpg. Very good for a V8. see full Lexus GX review

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

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
