2027 Mercedes-Benz GLS

The three-row GLS serves as the SUV equivalent to Mercedes-Benz's top-tier S-Class sedan, and its 2027 update comes with enough creature comforts and high-tech features to justify its flagship status. Flashy updates include a standard trio of 12.3-inch screens that span the dashboard, a massive 10.8-square-foot panoramic glass sunroof, air suspension that uses cloud data to automatically adjust to compensate for bumps ahead, and enough three-pointed Mercedes star logos on the GLS's exterior to form a galaxy. Two powertrains carry over from the outgoing GLS, both of which incorporate a 48-volt mild-hybrid system and have been updated to be smoother, more responsive, and quieter: a 375-hp turbocharged six-cylinder engine in the GLS 450 and a 530-hp turbocharged V8 in the GLS 580.

Brand context

About Mercedes-Benz

<p>Most Mercedes-Benzes give their owners industry-leading comfort and technology. The cost of that experience is typically a lofty base price with expensive options and below-average reliability. The brand produces a wide variety of vehicles for the U.S., including coupes, sedans, convertibles, and even two-seat sports cars. Some 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.</p>
