While it starts from the same four-door shape as the conventional C-Class, the C63 AMG looks the bahn-burning part, thanks to wheel flares and a bubbled-up hood-an "aggressive-looking body," as AutoWeek reports, as well as new front and rear bumpers, new badges, air intakes, and LED taillamps. Automobile says it's a "gung-ho street fighter," while the Detroit News compares it to a "fashion model snaking into a pair of tight jeans." The somewhat busy exterior shape could stand less visual jazz, but the roofline's tapering arc grows more appealing over time. BusinessWeek asserts, "it's clear that something wicked has overtaken the C-Class [and] muted its sometimes awkward look," and MyRide comments in comparison to the BMW M3, the C63 AMG is "downright subtle." It's certainly more dramatic and edgier than the former C-Class, and the C63 in particular looks more expressive and imposing when it's on the road-"sheer, extroverted extravagance," in the words of ConsumerGuide.
The C63 AMG's interior was refined last year and has a simpler, cleaner design with large and clear AMG gauges, metallic trim on the shift paddles and dash, and an audio system hobnailed with identical black buttons. A pop-up navigation screen rises from the middle of the dash when in use. Edmunds describes the 2010 Mercedes-Benz C63 AMG's interior as "well-crafted" but "a bit austere," while Automobile calls it "a functional and well put together driver's environment." MyRide mentions the "newly developed AMG leather sport seats, a three-spoke AMG sport steering wheel with aluminum shifter paddles and an AMG gauge cluster," pointing out that although "none of that makes it any faster ... it does carry the sporting motif inside."
