What Makes The GLS Stand Out?
True three-row luxury. Unlike some “3-row” SUVs where the last row is an afterthought, the GLS’s third row is genuinely usable for adults on shorter trips, and every row gets a comfortable, well-insulated ride.
A real prestige SUV. The GLS is frequently chosen by executives and public figures who want SUV practicality without stepping down from S-Class-level presence.
A wide performance range. From the composed, efficient GLS 450 to the handcrafted, 603-hp AMG GLS 63, the lineup covers everything from family comfort to genuine performance.
Cutting-edge technology. Standard tech includes a 12.3-inch digital instrument cluster paired with a 12.3-inch touchscreen, a 13-speaker Burmester sound system (26-speaker system optional), and augmented-reality navigation. Rear-seat passengers can option the MBUX High-End Rear Seat Entertainment System with twin screens for streaming and video calls a similar concept to what we covered in our BMW Theatre Screen guide, if you’re comparing luxury rear-seat tech across brands.
A genuine status symbol. Between its size, presence, and the range-topping Maybach variant, the GLS remains one of the most recognizable luxury SUVs on the road.
GLS Trim Breakdown
- GLS 450 4MATIC The entry point, built around a 375-hp turbocharged inline-6 mild hybrid. Best for buyers who want GLS luxury without stepping into V8 territory.
- GLS 580 4MATIC Steps up to a 510-hp bi-turbo V8 mild hybrid, with added comfort features like multi contour massage seats and a five-zone climate system.
- AMG GLS 63 The performance flagship, with a handcrafted 603-hp V8 biturbo, AMG-specific suspension tuning, and sports-car-like acceleration in a seven-seat body.
Mercedes-Maybach GLS 600 The ultra-luxury variant, available with a 4-seat VIP lounge layout, exclusive design elements, and the most opulent finishes in the lineup.
How The GLS Compares To Rivals?
The GLS’s closest competitors are the BMW X7 and the Range Rover (long-wheelbase). The GLS beats the X7 on third-row cargo space (17.4 cu ft versus 12.8 cu ft), while the Range Rover LWB out-hauls both with 92.8 cu ft of maximum cargo space. If you’re cross-shopping, the decision usually comes down to whether you prioritize Mercedes’ tech-forward cabin, BMW’s driving dynamics, or Range Rover’s off-road pedigree and outright cargo capacity. Full specs and configurator options are available on Mercedes-Benz’s official GLS page.
