Mercedes-AMG will send a clear message that it is adapting to modern demands with the upcoming third-generation C63 by forgoing its long-standing V8 power in favor of an advanced four-cylinder hybrid drivetrain that develops more than 500 HP.
The new C63 will be the first in a number of new AMG models earmarked to receive an electrified version of Mercedes’ new turbocharged 2.0-liter M139 engine when it goes on sale in early 2022.
The four-wheel-drive rival to the Audi RS4 and BMW M3 is already undergoing intensive development at AMG’s Affalterbach engineering headquarters.
Potency
The potent four-cylinder engine kicks out a maximum of 422 HP and 369lb ft of torque in non-electrified form in the new A45 and its related siblings. The unit has already been engineered for longitudinal mounting as well as mild-hybrid electric boosting. It’s destined to be used in not only the next C63 but also, in a less heavily tuned form, in a follow-up to today’s turbocharged 3.0-liter V6-powered C43.
The new C63 will be offered in sedan, coupé and convertible bodystyles, with the next C43 likely to be sold in those three guises as well as an wagon version.
Other AMG models set to run the new electrified driveline include successor models to today’s GLC 43 and GLC 63 SUVs, the GLC 43 Coupé and the GLC 63 Coupé.
48V
Autocar has been told the M139 engine will adopt a 48V integrated starter motor similar to that already used by the turbocharged 3.0-liter in-line six-cylinder M256 unit, which powers the CLS 53 4Matic+ and other recent new AMG models.
