Mercedes Benz CLK-Class

New to the CLK-Class this year is an AMG-inspired CLK63 AMG Black Series Coupe with more than 500 horsepower. The CLK63 joins the CLK63 AMG Cabriolet (475 hp, 465 lb.-ft.), CLK550 (382 hp, 391 lb.-ft.) and CLK350 (268 hp, 258 lb.-ft.). In addition, the CLK350 receives standard sport suspension and twin six-spoke 18-inch wheels.

The Black Series model is powered by the first engine designed totally by AMG. One of the most powerful naturally aspirated production V8s ever, the new engine boasts a wealth of features derived from AMG's highly successful racing heritage. Built almost completely from a high-strength silicon-aluminum alloy, the 6.3-liter V8 features four valves per cylinder, variable valve timing, bucket followers (rather than rocker arms) and a variable intake manifold.
