Following the unveiling of the new Mercedes-Benz C-Class, we all knew it wouldn't be long before AMG would have their turn at the new baby Benz. Sure enough, spy photos have begun hitting the internet, showing the next C63 AMG undergoing testing at the fabled Nurburgring.

Set to face off against the likes of BMW's upcoming (albeit manual and two-door) M3 and Audi's all-wheel-drive RS4, the C63 is anticipated to shoehorn in AMG's prolific 6.3-liter V8, though detuned to somewhere in the neighborhood of a magical 420 horsepower.

Major aftermarket tuners like Brabus, Kicherer and Lorinser have already revealed their modifications for the new C-Class, but only AMG will be able to provide the dealer-direct, factory-backed final product that you're likely to see ripping up your local streets. Expect the C63 AMG to make its debut at the Frankfurt show in September.
