Consider the C-class as all that Mercedes knows about full-size luxury, distilled into a smaller package. As a coupe, it offers a 201-hp turbo four-cylinder or a 302-hp V-6 and rear-wheel drive; as a sedan, it can be had with a 241-hp turbo four or a 329-hp twin-turbo V-6. All feature a seven-speed automatic. Both sedans have all-wheel drive; a rear-wheel-drive sedan with the 241-hp engine is available. In the fall of 2015 a C450 AMG with a 362-hp V-6 will go on sale, as will a plug-in hybrid.
