Originally introduced in 2004, the CLS was one of the first four-door luxury coupes to hit the market. The third generation made its debut in 2019 and is still going strong. Customers can turn to the base CLS 450 4Matic, which uses a turbocharged 3.0-litre six-cylinder engine, or the sportier and more upscale AMG 53 4MATIC+, which increases output from 362 horsepower to 429 horsepower. As the names imply, all-wheel drive is standard in both cases.
