Are C63 engines reliable?
The C63 is a good car worth buying, if it hasn’t been thrashed and had a good record of regular servicing. With that sort of mileage on it you should be able to enjoy many years of reliable and fun motoring in the future. In 1998, Mercedes revealed the CLK GTR FIA GT1 racing car, powered by a 6. M120 V12.Mercedes-AMG C63. Powerful plug-in-hybrid powertrain, poised handling, all the interior luxuries of a C-class with a sportier character. Lacks the previous model’s throaty V-8 roar, hardly any electric-only driving capability, powertrain complexity adds weight.
How much horsepower does the AMG C63 performance have?
The 2025 Mercedes-AMG C63 S E Performance replaces the thundering V-8 with a brainy plug-in hybrid system that combines one four-cylinder engine, two transmissions, and three motors to shock all four tires with a spectacular 671 horsepower and 752 lb-ft of torque. The four-cylinder, plug-in-hybrid Mercedes-AMG C63 was never a big hit. In our review, we called it a technical masterpiece with no soul. Now it appears Mercedes agrees: The four-banger C63 is reportedly headed for the chopping block.
