What Changed

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. Even though both engines are smaller in displacement, they are more powerful and fuel efficient. The CLS550 has a 7-speed automatic and the CLS63 includes a dual-clutch 7-speed automatic.
