Mercedes-Benz S-Class Real Gas Mileage: Pros
YearBody/PowertrainComment
2007 4dr Sedan, ext. 382-horsepower 5.5L V8
7-speed shiftable automatic RWD		 Since my driving is about 50-50 city and highway, I average about 20-21 mpg, using premium fuel. All highway is 29-30mpg and all city is 14-15mpg. see full Mercedes-Benz S-Class review
2007 0 While on long trips at 70-80mph I average 32mpg around town it never goes better than 24mpg. Easy on the pedal sure shows results but fully loaded the thing shifts like a two door sports. see full Mercedes-Benz S-Class review
