What it gives in performance, the 2010 C63 AMG takes away in rear-seat room.
Front-seat passengers have plenty of room in "coddling" AMG sport seats that BusinessWeek says "nestle up about perfectly." The driving position in the 2010 C-Class is quite good, between the telescoping steering wheel, the power driver seat, and the car's tall, glassy cabin.
Edmunds reports this C63 "has grown up only ever so slightly from the last generation" of C-Class, and it's noticeable in the backseat, where taller adults will have to lean over to fit. ConsumerGuide says, "the C63 has the same tight cabin as any other C-Class model...Rear-seaters are frankly cramped with six-footers up front, so for all practical purposes this nominal four-passenger sedan is a two-adults-plus-two-kids proposition." All rear passengers will find legroom at a premium, even when the front passengers inch forward. The C63 AMG's black upholstery adds to the sense of confinement. Edmunds concludes the interior is "austere and not very spacious."
The trunk space is big enough for a family's long weekend of luggage, though, at 12.4 cubic feet. The trunk can be expanded by folding down the rear seats, according to BusinessWeek.
The C-Class's fit and finish benefit from fewer pieces, fewer cutlines, and simpler styling, and are much improved over the prior generation, though some interior finishes and functions are deemed less than perfect by writers from major auto Web sites. The Detroit News reports the C63 AMG "lacks daytime lighting for the instruments," adding that "the sun visors do not slide on their support rods to block the sun from the side." ConsumerGuide expresses some disappointment in the "amount of hard, industrial-looking plastic," though they observe sound levels are "good by performance-car standards."
