The 2023 Mercedes-Benz C-Class welcomes a new addition to the lineup this year: the high-performance AMG C 43, which adds a dash of excitement to the C 300's focus on comfort and luxury. The changes for the new C 43, like the C 300, only apply to the sedan. Mercedes will continue to sell the coupe and convertible versions of the C-Class for the 2023 model year, but the two-doors are still based on the fourth-generation C-Class rather than the fifth-generation sedan. The new AMG C 43 sedan drops two cylinders, giving it a turbocharged 2.0-liter four-cylinder instead of the V6 found in the previous model. It also gets a mild hybrid system like the C 300, but the emphasis here is on performance and not efficiency.
