  • It has a luxurious cabin with adjustable seats.

  • Adequate cargo capacity is provided.
  • It has efficient engines.


  • It provides a steep, infotainment learning curve.


The 2021 Mercedes-Benz GLS-Class standard interior is attractively designed and intelligently engineered. The cabin of the 2021 Mercedes-Benz AMG GLS 63 S is virtually the same, although you get an AMG steering wheel, luxurious Nappa leather, and sports front seats with wider side bolster to hold you in place as you carve via turns.

Mercedes’ prominent three luxury SUVs are the 2021 Mercedes-Benz GLS 580, GLS 63, and GLS 600. Henceforth, the different engines are featured in each 2021 Mercedes-Benz GLS model. A 362-horsepower turbocharged inline six-cylinder comes with the base 450.

The 2021 Mercedes-Benz GLS 580 has a twin-turbo V8 with 483 horsepower.

The 2021 Mercedes-Benz AMG GLS 63 and Maybach GLS 600 have 603 and 550 horsepower, respectively. Also featuring twin-turbo V8s, all models come with an automatic nine-speed transmission.

Even the inline-six is lively, and the mild-hybrid EQ Boost system gives it a little extra jolt during acceleration. None of these engines sounds low. The V8-powered GLS models are more energetic, and the high-performance AMG model provides acceleration worthy of sports cars.

Two large 12.3-inch digital displays occupy most of the dashboard: one acts as a reconfigurable gauge monitor for the driver, while the other performs infotainment activities and runs the latest MBUX app from Mercedes-Benz, which features a virtual assistant like an iPhone. In-dash navigation, Apple CarPlay and Android Auto capability, and an onboard Wi-Fi hotspot are all standards.

A 13-speaker Burmester Surround Sound stereo arises with all 2021 Mercedes-Benz GLS models, but if that isn’t enough for you, there’s a Burmester 3D audio system with a fantastic 26-speaker arrangement available.
