2015 Mercedes-Benz C-Class: What's New, Specs & Features
Last updated August 4, 2026
The biggest change for 2015 is the debut of the fully redesigned W205 C-Class sedan, with a roomier cabin, richer interior, new turbocharged engines and more technology. The coupe remains on the older W204 platform for one final model year.
About the 2015 Mercedes-Benz C-Class
Split-generation year: W205 sedan, first year in the U.S.; W204 coupe and coupe-based AMG models, final U.S. year.
The 2015 C-Class is Mercedes-Benz's compact luxury car, aimed at shoppers who want a smaller car without giving up the brand's comfort, design, and technology feel. In sedan form, Mercedes positions it as a more attainable version of the big-car experience, with a rich cabin and advanced safety features. The coupe side leans more toward sleek style and sporty driving, while AMG models turn the same basic formula into serious rear-drive performance cars.
The C 300 is the core luxury-sport sedan, while the C 400 4MATIC adds a 329-hp twin-turbo V6, all-wheel drive, premium audio and LED headlights. At the top, the new C 63 S sedan uses a 503-hp twin-turbo V8, while the two-door lineup still includes the older V6 coupes and the 507-hp C 63 AMG Edition 507.
What changed, by category
Structural
The sedan moves to the new W205 platform, bringing a larger, roomier cabin. The coupe continues on the older W204 platform.
Styling
The redesigned sedan receives a new body and a substantially more upscale cabin design. The coupe’s older-generation design carries over.
Powertrain
The new C 300 sedan gets a 241-hp 2.0-liter turbo four-cylinder, and the new C 400 4MATIC gets a 329-hp twin-turbo V6 with all-wheel drive. The redesigned AMG sedans switch to a twin-turbo 4.0-liter V8, including a 503-hp version in the new C 63 S.
Tech
The redesigned sedan adds touchpad-based controls, a standard 7-inch center display and five selectable drive modes. Heated front seats, premium audio and satellite radio become standard on the C 250 coupe, while remote start becomes standard on the C 350 coupes and AMG models.
Safety
The redesigned sedan brings a major expansion in safety and driver-assistance technology compared with the previous-generation sedan.

2015 Mercedes-Benz C-Class
(920 reviews)
“Fuel Mileage is the worst of the last four Mercedes I've owned, including an E320 and E350, and the noisiest interior of any Mercedes I've had. The engine sounds like a sewing machine, and the transmission occasionally jerks on slowing. Certainly not like all my previous [Name].”
“Radio system is not user friendly. Much preferred previous model that had preset buttons. This system is too hard to navigate while driving”
