If you want the most technology in your performance car, look no further than the 2025 Mercedes-AMG C63 S E Performance, a plug-in hybrid super sedan that’s as complex as its name is long. Plug-in hybrids like the C63 are how Mercedes’ legendary AMG performance division aims to achieve modern performance while it continues to develop the tech for true high-performance EVs. While it still burns some gasoline, the 2025 C63 is a big improvement over its predecessor in terms of efficiency, swapping a thirsty V8 engine for one with half the cylinders that’s assisted by electric power.
Car enthusiasts will be feeling a sense of déjà vu because this is the same powertrain used in the GLC63 S E Performance crossover SUV, which is also new for 2025. Mercedes actually announced the C63 first, but the nature of media event scheduling means we drove the GLC63 earlier — and found it to be impressive, but puzzling. But, as a sedan, the C63 has the advantages of a lower center of gravity and less weight, giving the plug-in hybrid powertrain and its attendant driver aids a better chance to win our hearts.
Design and interior The C63 bulks up the styling of the current-generation Mercedes-Benz C-Class, which arrived for the 2022 model year, but hasn’t been offered with a plug-in option until now. Ribs in the hood recall past Mercedes sports cars. The fenders are pushed out, and larger front air intakes hint at the hardcore hardware beneath the skin.
In the best AMG tradition, it.
