About the 2010 Mercedes-Benz CLS
1st gen (C219/W219), after the 2009 refresh; second-to-last US model year before the all-new 2012 CLS redesign.
Mercedes-Benz positioned the CLS as the original four-door coupe: a lower, sleeker, more emotional alternative to a traditional luxury sedan. Its appeal was not maximum rear-seat space or value. The draw was dramatic styling, strong V8 power, a tailored four-seat cabin, and Mercedes comfort and safety engineering. For most buyers, the CLS was the car you chose when you wanted coupe style and grand-touring character without giving up rear doors.
The CLS550 is the stylish core model, pairing a 382-hp V8 with an air suspension, hard-drive navigation, surround-sound audio, and four individual seats. The CLS63 AMG is the performance version, with a 507-hp AMG V8, quicker-shifting transmission, larger brakes, sportier suspension tuning, and a leather-and-Alcantara cabin.
