The inspiration behind the creation of the CLS was, according to Mercedes, "to combine the emotional appeal and dynamic design of a coupe with the comfort and functionality of a sedan." And while on a price list the CLS-Class slots neatly between Mercedes' E- and S-Class sedans, its unique styling successfully sets the vehicle apart within both Mercedes' lineup and the entire luxury sedan landscape. In addition to the CLS500, there's a CLS55 AMG version featuring a supercharged 5.5-liter V8 good for 469 horsepower that, according to Mercedes, is strong enough to hurl the 4,000-pound sedan from 0 to 60 mph in just 4.5 seconds.
