The Mercedes-Benz CLS was introduced for the 2005 model year and went on sale in the United States in January 2005. Based on the previous-generation E-Class, the four-door coupe started a whole niche in the automotive industry, soon to be followed by Audi and BMW. The first-generation model was offered with a bevy of V-6 and V-8 engines that delivered as much as 507 horsepower. The second-generation coupe arrived in 2010, but the U.S.-spec version didn’t arrive until the 2012 model year. Unlike its predecessor, the current model gained a 4.7-liter V-8 and a 2.1-liter, inline-four diesel to go with the already available 3.0-liter oil burner. The Shooting Brake body style was introduced in late 2012, but without being green lighted for the U.S. market. In 2015, the CLS is set for a facelift.
