The 2025 Mercedes-Benz GLS 580 4MATIC is a pinnacle of luxury SUVs, blending opulent comfort with robust performance. Powered by a twin-turbo 4.0-liter V8 with a 48-volt mild-hybrid system, it delivers 510 horsepower and 538 lb-ft of torque, achieving 0-60 mph in a brisk 4.7 seconds.
The nine-speed automatic transmission and all-wheel drive ensure smooth, confident handling, though its size limits agility on tight roads. The standard air suspension, with optional E-Active Body Control, provides a plush ride, absorbing road imperfections effortlessly, making it ideal for long-distance cruising.
Inside, the GLS 580 offers a first-class cabin with premium materials, though some plastics detract slightly from the ultra-luxury feel. Seating for up to seven (or six with captain’s chairs) is spacious, with a third row suitable for adults. The dual 12.3-inch displays running MBUX infotainment are intuitive, supporting Apple CarPlay, Android Auto, and a Burmester audio system. Advanced safety features like adaptive cruise control, lane-keeping assist, and evasive steering assist come standard.
Fuel economy is a drawback, with EPA estimates of 14 mpg city and 19 mpg highway, typical for a V8-powered SUV. Starting at around $115,950, the GLS 580’s price can climb with options like the Pinnacle trim or 23-inch AMG wheels, reaching $128,000 as tested. While not as bold as the BMW X7 or as rugged as the Jeep Grand Wagoneer, it strikes a balance of elegance and capability. Towing up to 7,700 pounds and optional off-road features add versatility. The GLS 580 excels as a luxurious family hauler but requires a premium budget.
We give it 4.5 Lambos.
