2023 Mercedes-Benz C-Class: What's New, Specs & Features
Last updated August 4, 2026
The main change for the 2023 Mercedes-Benz C-Class is the arrival of the AMG C 43 sedan. The regular C 300 and C 300 4MATIC receive no major equipment, styling, or mechanical updates.
About the 2023 Mercedes-Benz C-Class
Split-generation year: the sedan is the fifth-generation C-Class in its second year, while the coupe and cabriolet are the previous-generation two-door models in their final U.S. year before the CLE replacement.
Mercedes-Benz positions the C-Class as a smaller luxury car with much of the brand's larger-car feel: upscale cabin design, strong turbo power, and everyday comfort wrapped in a more manageable size. In 2023, it also gives buyers three personalities under one name: a modern tech-heavy sedan, a sleeker coupe, and an open-air cabriolet. Its core appeal is getting Mercedes style, comfort, and prestige without stepping up to a bigger E-Class or S-Class.
The 2023 C-Class spans two designs: the recently redesigned sedan and the older coupe and cabriolet, which are in their final U.S. model year. Regular C 300 models pair a turbocharged four-cylinder engine with a nine-speed automatic, while the C 300 4MATIC adds all-wheel drive. Heated power front seats with memory settings, Apple CarPlay, and Android Auto are notable comfort and convenience features.
