2012 Mercedes-Benz C-Class coupe
The C-Class adds a two-door model for the first time since Mercedes dropped the hatchback from the US lineup in 2006. The C-Class coupe is almost identical in size to its German rivals, the BMW 3-Series and Audi A5. Three engines are offered: a 1.8l turbocharged four-cylinder, a 3.5l V6, and a 6.2l V8. A seven-speed automatic is standard on C250 and C350 models, whereas the C63 AMG is equipped with a 7-speed sequential manual.
2012 Mercedes-Benz CLS-Class
The second generation CLS-Class debuted for the 2012 model year. The new CLS retains the overall sleek profile, but wears harder styling lines and a more upright grille. In terms of size, the new model is slightly longer (.9 inches) and wider (.4 inches). Under the hood, the CLS offers two new engines. The CLS550 is powered by a 4.7-liter V8 engine rated at 402-bhp, whereas the CLS63 AMG utilizes a 5.5-liter V8 rated at 518-bhp.

Mercedes offers the US model with either a 1.8l four-cylinder engine (SLK250) or a 3.5l V6 (SLK350). A six-speed manual is standard on the SLK250, with a seven-speed automatic optional.
