AMG working on new 4.0L V8
Drivers won't see a cut in power with the move, however. The report says the forced-induction 4.0-liter will deliver 450 horsepower – just under the 451 hp served up by the current C63 AMG. What's more, the engine will likely be capable of generating up to 600 horsepower. That means it could go on to supplant even the 5.5-liter V8 in the SLK55 AMG. While AMG hasn't outright confirmed the 4.0-liter powerplant, Mercedes-Benz AMG CEO Ola Kallenius has made it clear his organization will continue to focus on downsizing engine options in the future.
