We achieved an average of 20.1 mpg during mixed city and freeway driving [C350]
With both the Mercedes-Benz C Class, as well as another sport-sedan benchmark, the BMW 3-Series, going to base four-cylinder engines over the past year, fuel efficiency is now quite good for these premium sedans and coupes. At the far opposite end of the spectrum, the V-8-powered C 63 AMG earns ratings that are shockingly low for a compact coupe.
The C250 sedan scores 21 mpg city and 31 mpg highway for 25 mpg combined, according to the EPA. The C250 coupe matches the sedan's figures.
We can't yet give you official numbers for the 2013 C 300 4Matic, which got a new engine this year and hasn't yet been rated, but the C350 sedan has fared quite well, at 20 mpg city and 29 mpg highway for 23 mpg combined. At 19/28 mpg, the C350 coupe scores slightly worse.
It's no surprise that the powerful C 63 AMG, with its huge V-8, is something of a boat anchor fuel fuel economy--even though it's a rocket ship in performance. It scores an estimated 13/19 mpg for 15 mpg combined according to the EPA.
Fuel-efficiency is decent with the four-cylinder or V-6 engines, but its no surprise that the C 63 AMG is a guzzler.
