The Mercedes-Benz C-Class used to offer a selection of six- and eight-cylinder engines as part of an elegant lineup of sedans, coupes and convertibles. Today, the C-Class is available exclusively as a four-door sedan with a single four-cylinder engine. However, the story doesn’t end there. In addition to the base 300 4MATIC model producing 255 hp, there are explosive AMG models to choose from, one of which adds an electric motor and delivers up to 671 hp.
