Mercedes-Benz has unveiled the updated GLS, marking the second refresh for the flagship SUV in its current generation. The focus lies on the interior, technology, and powertrain refinements.

Interior with a focus on passenger comfort

The most significant changes are inside. The GLS features an interior inspired by the latest S-Class, complete with the signature Superscreen and an augmented reality head-up display.

Special attention is given to rear passengers. They get two separate 11.2-inch screens for watching videos or joining video calls. Controlling features feels smartphone-like, allowing adjustment of seats, lighting, and media.

In the seven-seat version, practicality is improved—the second row can now be slid forward to increase space in the third row.

Design and technical updates

Externally, the GLS features new headlights, a radiator grille, and a revised rear light signature. New body colors and wheels up to 23 inches are available.

Under the hood, the engine lineup is modernized. The GLS 450 gets an updated inline-six with 375 horsepower, while the top-tier GLS 580 is equipped with a V8 producing 530 horsepower, accelerating from 0 to 100 km/h in 4.7 seconds.

All versions come with all-wheel drive and an automatic transmission.

Positioning without hybrids

Unlike the smaller GLE, the GLS has not yet received a plug-in hybrid. However, more powerful AMG versions are expected later, strengthening the model's position in the segment.

Overall, the updated GLS highlights a shift in premium segment logic: luxury is no longer just about materials and power, but the quality of experience for second-row passengers. In practice, Mercedes is turning the GLS into an alternative to executive sedans for those who don't want to sacrifice space and versatility. This reflects a global trend, with models like the Bentley Bentayga, Range Rover, and even Chinese premium brands increasingly betting on the "second row." Against this backdrop, the GLS is no longer just a large SUV—it becomes a mobile lounge space where the driver isn't always the most important person in the car.
