2022 Mercedes-Benz GLS

The new for 2020 GLS is a very functional three-row SUV that exudes luxury with its gorgeous interior. The standard 3.0-liter six-cylinder turbo provides plenty of smooth and effortless power. An even more powerful turbocharged V8 is available. The ride is very composed and handling is responsive for such a luxury coach. All of the seats are first-rate, and the interior can be configured for either six or seven passengers. Unlike most competitors, the third-row seat is relatively roomy. However, the infotainment system is overly distracting because many common tasks require a few steps. Using steering-wheel controls too easily ends up changing a display or audio selection. Standard safety features include forward collision warning and automatic emergency braking.

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.
