What Is the 2025 Mercedes-Benz GLS?

The Mercedes-Benz GLS is a full-size SUV that can seat up to seven people in three rows. It’s powered by a 375-horsepower, turbocharged inline-six-cylinder engine (450) or 510-hp, twin-turbo V-8 (580). The ultraluxury Maybach GLS600 and high-performance AMG GLS63 get a twin-turbo V-8 with 550 and 603 hp, respectively. All GLS models come standard with all-wheel drive. There’s enough room for adults in all three rows, which isn’t always the case even in extra-large SUVs. GLS competitors include the BMW X7, Audi Q7, Cadillac Escalade, Jeep Grand Wagoneer and Porsche Cayenne.

What’s New on the 2025 Mercedes-Benz GLS?

After a 2024 refresh, the GLS mostly stands pat for 2025. All trims now come with a biometric fingerprint sensor, and several special-order Manufaktur paint colors and trim choices are newly available. 

What Features in the 2025 Mercedes-Benz GLS Are Most Important?

Standard features include: 

  • Synthetic leather upholstery
  • 12.3-inch digital instrument panel
  • 12.3-inch infotainment screen
  • Apple CarPlay and Android Auto 
  • Navigation
  • Satellite radio
  • 13-speaker Burmester stereo system
  • Panoramic moonroof
  • Wireless device charging
  • Blind spot warning
  • 360-degree camera system 

Available features include: 

  • 26-speaker Burmester stereo system
  • Head-up instrument display
  • Front and rear cross-traffic alert
  • Adaptive cruise control
  • Five-zone climate control
  • Massaging front seats
  • Heated armrests
  • Heated and cooled cupholders

Should I Buy the 2025 Mercedes-Benz GLS?

The Mercedes-Benz GLS is a very luxurious way to transport lots of people and all of their luggage from Point A to Point B. With powerful engines and a commanding view of the road, the GLS has tons of road presence; it feels worth its admittedly high asking price. A digital instrument panel sits flush with the infotainment screen, creating an attractive display that takes a lot of practice to learn. Other than some quirky voice commands and its fuel-guzzling nature, there are few things to nitpick in Mercedes’ largest SUV.

  • I’ve had many Mercedes-Benz models over the years,

    I’ve had many Mercedes-Benz models over the years, including AMG’s and the GLS 450 a wheel drive with 23 inch wheels makes this car track like a race car. Out of all the Mercedes-Benz models this is the best one you’ve ever had. The second row seats reclining just like the front row seats privacy shades and the third row comes in handy when needed plenty of cargo space for all those trips to the airport to pick up family and friends. It gets great gas mileage then other SUVs and it doesn’t look like a box like it’s competition. I had the dealer put the Mercedes-Benz standup medallion on the hood even though it has a huge Mercedes-Benz insignia on the front. I just like to see the stand up Star medallion from the driver seat guide me down the road..
