2020 Mercedes-Benz CLS: What's New, Specs & Features

About the 2020 Mercedes-Benz CLS
3rd generation (C257), second U.S. model year after the 2019 redesign
Mercedes-Benz positions the CLS as the original modern four-door coupe: a style-led luxury car that puts sleek design, craftsmanship, and a graceful driving feel ahead of maximum practicality. It sits between the more conventional E-Class and the larger, more formal S-Class in spirit, offering a dramatic roofline, rich cabin materials, and smooth six-cylinder power for buyers who want their daily driver to feel more special and more design-focused than a typical midsize luxury sedan.
Mercedes positioned the CLS 450 as an elegant, style-focused four-door coupe with a sweeping roofline and a smooth turbocharged inline-6 supported by mild-hybrid assist. Both versions have leather upholstery, heated front seats, navigation, a 12.3-inch center display, Apple CarPlay, Android Auto, and several driver-assistance features. The CLS 450 has rear-wheel drive, while the CLS 450 4MATIC adds all-wheel drive for better traction on slippery roads.

2020 Mercedes-Benz CLS Reviews
What owners are saying about the 2020 Mercedes-Benz CLS.
“The safety features are irreplaceable. The vehicle has the necessary safety features. The vehicle is extremely comfortable and has a smooth ride and driving capability.”
“It is a fun car to own and drive. If you are tall like me (6'5"), it should not be considered as your primary car. I bought the car for my wife who is 5'2" and fits her perfectly. So, if you are a normally proportioned person, it is an excellent car provided you have the finances to acquire and maintain.”
