Three gasoline engines

In the top-of-the-range model, the E500 Coupe, the muscular V8 engine with 388 horsepower and 391 pound-feet of torque offers the performance characteristics of a sports car.

The E250 CGI BlueEfficiency Coupe features a newly developed four-cylinder direct-injection unit that outputs 204 horsepower while averaging 33.6 mpg. A five-speed automatic transmission is coupled with this engine as standard. Stepping up to the V-6 E 350 CGI BlueEfficiency Coupe nets you 292 horsepower and just 27.7 calculated miles per gallon. Both engines feature spray-guided gasoline direct-injection.
