Spied here undergoing testing in its native Germany, this is the second time we're getting a glimpse at the upcoming new C63, but while it may be wearing just as much camouflage as last time, the lighter, drier conditions give us a bit of a better look. Seemingly understated for an AMG model, the new C63 will still sport large air openings in the front bumper and small vents flanking the rear through which protrude four squared-off exhaust tips. There's also a bit of an aerodynamic lip to the rear bumper, along with some serious-looking alloys wearing beefy, low-profile rubber.

Of course, what will really matter is what's under the hood. And that's expected to be a new 4.0-liter twin-turbo V8 producing between 450 and 500 horsepower, which even on the bottom end would make it more powerful than its chief rival, the latest BMW M3 with its 425-horsepower 3.0-liter turbo six. Whether Mercedes offers the new C63 with 4Matic all-wheel drive – as standard or optional – remains to be seen, but we're expecting the new model to be unveiled early next year, so we'll find out in due course.
