Review and specifications

2020 Mercedes-Benz SL

This generation brought a significantly revised car, one that is wider, longer and fitted with a host of high-tech safety features. While we appreciate the outstanding fit, finish and creature comforts, the look of this version of the SL leaves us somewhat cold. The previous design looks much better. With that said, exceptionally powerful turbocharged V8 and V12 engines are offered, along with an adjustable-opacity feature for the folding hardtop. Practically every known electronic driver's assistance safety feature is also available. Ride quality and handling are unsurpassed, with the SL performing like a much smaller and lighter sports car when called upon to do so, while providing outstanding smoothness and ride comfort when it is required.

Brand context

About Mercedes-Benz

Most Mercedes-Benzes give their owners industry-leading comfort and technology. The cost of that experience is an expensive base price with expensive options and below-average reliability. The brand produces a wide variety of vehicles for the U.S., including coupes, station wagons, sedans, convertibles, and even two-seat sports cars. Its two- and three-row SUVs that we’ve tested have powerful engines and interiors that are roomy and quiet. Generally, Mercedes-Benz fit and finish, inside and out, is exceptional and helps justify prices. Mercedes-Benz’s EVs range from compact to large three-row SUVs. Across the lineup, controls for the complex climate and infotainment systems aren’t as intuitive as we find in other luxury vehicles. Like most European luxury brands, used Mercedes-Benzes can have expensive out-of-warranty repairs, although Consumer Reports has found used models with above-average reliability.
