Confirmed - C63 AMG Black Series will receive tuned M156 6.2 liter V8 around 510 horsepower, $100k base
A Mercedes-Benz AMG inside source has confirmed the M156 V8 in a higher state of tune will be used in the C63 AMG Black Series. MotorAuthority
who reported they confirmed an M157 twin turbo V8 would be used were wrong. It would appear P31 or SLS forged engine internals will be standard. It will not be an M159 (SLS motor) but will likely share similarities such as the heads but not the SLS intake manifold or airboxes due to not being able to fit in the C engine bay. Base price is expected to be $100k.
