About the 2021 Mercedes-Benz AMG C-Class
4th-generation C-Class (W205 sedan, C205 coupe, A205 cabriolet), third model year after the 2019 refresh; final year for this generation’s US AMG sedans, while the coupe and cabriolet designs extended into 2022.
Mercedes-AMG positions the C-Class as a compact luxury performance car shaped by its racing experience but usable beyond a racetrack. Sedan, coupe, and cabriolet forms combine a high-quality cabin with strong acceleration and adjustable suspension settings. The C 43 emphasizes all-weather traction and daily usability, while the C 63 models add handcrafted V8 power, rear-wheel drive, and more specialized handling hardware.
The C 43 was the everyday-friendly model, pairing a 385-hp twin-turbo V6 with rear-biased AWD, while the rear-wheel-drive C 63 and C 63 S used 469-hp and 503-hp twin-turbo V8s. All three came as sedans, coupes, and convertibles, with the C 63 S adding specialized performance hardware and Nappa leather.
