The successor to the existing naturally aspirated 6.2-litre V8 powered Mercedes-Benz C63 AMG will be powered by an all-new turbocharged 4.0-litre V8 powerplant that comes from Mercedes-Benz’s AMG performance off-shoot. This is the same unit that will be used for the future Mercedes SLC sports car. Mercedes developed the unit using modular lines.
It is believed to have the same individual cylinder capacity, bore centre spacing and other specs with the turbocharged 2.0-litre four-cylinder intended for the Mercedes A45 AMG and Mercedes CLA45 AMG.
Sources said that the new unit, which is expected to offer more than 450bhp in the first state of tune but could generate as much as 600bhp, will later replace the naturally aspirated 5.5-litre V8 that’s exclusively used by the Mercedes SLK55 AMG, offering a step upward to AMG’s bigger turbocharged 5.5-litre V8. AMG boss Ola Kallenius only implied that the company will soon offer smaller engines.
He didn’t officially confirm the new engine to Autocar at the Los Angeles motor show at the later part of last year. But he said that downsizing to 5.5 as well as more advanced direct-injection technology is to be expected in the future.
The successor to the C63 AMG will feature a new engine as well as be the first of the company’s performance saloons to be available with either rear- or four-wheel drive in right-hand drive versions.
