2009 Mercedes-Benz CLS: What's New, Specs & Features

About the 2009 Mercedes-Benz CLS
1st generation CLS (C219, 2006-2011 U.S.), late-cycle refresh year
Mercedes-Benz positions the CLS as the original four-door coupe: a car with the drama of a low, sleek coupe but the everyday usefulness of four doors and a usable trunk. In 2009, its identity is still built around style first, backed by V8 power, upscale materials, and Mercedes safety engineering. Compared with a more conventional luxury sedan, the CLS trades some rear-seat ease for a more emotional design and a more distinctive road presence.
The CLS 550 is the comfort-focused version, pairing a 382-hp V8 with air suspension, leather upholstery, four-zone climate control, and premium audio. The CLS 63 AMG is the sharper performance model, with a hand-built 507-hp V8, sport-tuned air suspension, stronger brakes, and AMG sport seats.
