Sounds like the next C63 will lose the big displacement and will move to a smaller motor with a hybrid powertrain:
“If you apply proper intelligent hybridization or electrification to a car which is capable of having an always-on strategy regarding the battery and the whole system, then it’s amazing what you can get out of them”, said Moers. “Which means for sure the next-generation Mercedes-AMG C63 will be a hybrid – that’s now a given.”
