2021 Mercedes-Benz C-Class: What's New, Specs & Features
Last updated August 4, 2026

About the 2021 Mercedes-Benz C-Class
4th-generation C-Class (W205 family). For 2021, the sedan is in its last US model year before the 2022 redesign, while the coupe and cabriolet stay on the same W205 generation beyond 2021.
Mercedes-Benz positions the C-Class as the compact luxury car that blends style, comfort, technology, and driver appeal without moving into full AMG territory. In 2021 it still spans three body styles—sedan, coupe, and cabriolet—so its main draw is choice within a single upscale formula. The core promise is a polished cabin, strong safety technology, turbocharged performance, and a more emotional design than many traditional small luxury rivals.
The C 300 remains the core luxury model, offered as a sedan, coupe, or convertible with a 255-hp turbocharged four-cylinder engine and a nine-speed automatic transmission. It has a 10.25-inch center display with Apple CarPlay and Android Auto, while the C 300 4MATIC adds all-wheel drive for better traction in poor weather.

“The trunk is non-existent and the interior is completely cramped. You can't even fit groceries in the trunk.”
“Superior build quality, excellent fit and finish, decent gas mileage, well styled. Only sits two however as the rear seats are very tight.”
