Mercedes-Benz calls its CLS-Class a "four-door coupe" It's technically a sedan, but its stance and sporty appearance do create the look of a coupe. The CLS-Class is a high-performance luxury car that's available with one of two V-8 engines; the larger, with the optional Performance package, makes a top speed of 186 mph, according to the manufacturer. The 2011 model is mainly a carryover from the previous year, but some previously optional features have been added as standard.
