The base E250 BlueTEC comes with a turbodiesel, four-cylinder engine that auto writers say provides plenty of power from a stop, as well as capable acceleration for highway passing. If you want more power, reviewers say that the V6-poweRed E350 offers impressive acceleration, while the high-performance E63 AMG delivers blistering acceleration and outstanding traction, thanks to its twin-turbocharged V8 engine and standard all-wheel drive. The EPA reports that the base E250 BlueTEC gets 28/45 mpg city/highway, which is outstanding for the class. The E-Class sedan earns praise for its spacious front and rear seats, and some reviewers note that there's plenty of headroom for taller drivers. Additionally, the Mercedes E-Class offers more trunk space than most cars in the class. Some reviewers say that the E-Class' standard COMAND infotainment system can be difficult to use, especially when compared with systems found in Audi and BMW vehicles.
