A four-seater, the coupe will compete with BMW in another entry-level luxury segment; there's also a possibility of a future convertible model, as well. At 180.7 inches, it is within 1.5 inches of the sedan's length and about an inch shorter than a BMW 3 Series coupe.
Two new direct-injection engines are used in the Mercedes coupe—a 229-hp, 1.8-liter turbocharged four cylinder for the C250 and a 302-hp, 3.5-liter V6 in the C350. Each engine is paired with a seven-speed automatic transmission.
Mercedes estimates that the C250 will get 24 mpg combined, with a 30 mpg on the highway. Zero-to-60 mph is a claimed 7.1 seconds with the four-cylinder engine.
The C350 will return an estimated 22 mpg overall. A fair bit quicker, the V6 version will reportedly hit 60 mph in under six seconds.
