For 2019, the Mercedes-Benz CLS got a full-on re-design. The body lines and contours of the 3rd generation CLS are clean and dramatic, with a laid back windshield and roofline, amplifying its speedy look. And speedy it is, powered by a 362-horse inline-6 with an integrated starter/generator and 48-volt onboard electrical system for improved efficiency and short-term power boosting.
