New for 2009, the CL550 benefits from Mercedes-Benz's 4Matic all-wheel-drive system, as opposed to the standard rear-wheel drive of last year's CL. This is indeed one elegant car. The CL is a machine of elegance and everything, from the fantastic multi-function LCD instrument panel to the climate control buttons, has an aura of quality and sophistication about it.Weighing in at 4,639 lbs, the CL550 uses its modest-for-the-size 382 hp to manage a startlingly quick sprint to 60 mph in just 5.3 seconds. The 4-Matic system moves power between all four wheels as needed, helping to keep the big CL in proper shape, especially on slippery, low-grip surfaces.
