Spy Shots: Mercedes-Benz prepping C63 AMG Black Series?

This set of spy photos landed in our inbox showing what appears to be a modified version of the giant-slaying Mercedes-Benz C63 AMG prepping for testing. Our spies indicate that this could be a high-powered Black Series version of the M3-killing C-Class, rumored to have around 510 horsepower. You know, because the standard 451-hp C63 just isn't sweet enough.

We know that the next-generation C-Class is due to arrive within the next couple of years (before the facelifted version arrives in 2011), so perhaps this is a sort of last hurrah for the top-dog C63. We can clearly see the tacked-on wider fender flares and front wheels similar to those that debuted on the CLK Black Series a few years back, and our spies suggest that a larger front spoiler and new rear diffuser will be added, as well. Power will still come from the same 6.2-liter V8 currently found in the C63, mated to a seven-speed AMG Speedshift transmission.

We're still a bit skeptical as to whether or not this is actually a full-on Black Series treatment. All we know is, we certainly wouldn't kick a 510-hp C63 AMG out of bed.
