Why it stands out

The 2025 Mercedes-Benz GLS stands out as the roomiest vehicle in the Mercedes-Benz lineup, with three rows of seating for six or seven people and up to 2,400 litres of cargo space. It is positioned as a midsize SUV for families, combining the comfort and space of the S-Class luxury sedan with some off-road capability, while also offering a premium cabin and easy-to-use technology. For 2025, a fingerprint scanner was standard on all trims, and new exterior and interior colours were added as part of the Manufaktur Signature range of options.

It also brings a strong mix of standard equipment and convenience features. The GLS includes dual 12.3-inch displays with MBUX touchscreen functionality, navigation, a Burmester surround sound stereo, SiriusXM, nine USB-C ports, wireless charging, and three years of Mercedes Me Connect services. Heated front seats, MB-Tex upholstery, a sunroof, power-folding third-row seats, power-adjustable second-row seats, and 19-inch wheels were also standard. The GLS 450 used a 3.0-litre inline six with 362 horsepower and 369 pound-feet of torque, while the GLS 580 offered a 4.0-litre V8 Biturbo with 483 hp and 516 lb-ft of torque. A 48-volt mild hybrid system called EQ Boost was fitted to reduce fuel consumption, enable faster and smoother engine restarts, and provide electric torque from a standstill.

There are some trade-offs, though. Front headroom decreased in the second generation, and the GLS was noted for third-row seat access and touch-sensing controls among its drawbacks. Even so, its appeal lies in how thoroughly it blends space, comfort, technology, and luxury in a single three-row package.
