2006 2dr Hardtop conv. supercharged 493hp 5.4L V8

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
YearBody/PowertrainComment
2002 2dr Hardtop conv. 302-horsepower 5.0L V8
5-speed automatic RWD
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
