Safety Rundown

ANCAP safety ratings have not been published for both models yet. We will update this section when crash test results are available.

Feature Showdown

The Mercedes-Benz G-Class features a 12.3-inch touchscreen paired with a 12.3-inch digital dash, while the Mercedes-Benz GLS-Class gets a 12.3-inch display and 12.3-inch instruments. Apple CarPlay and Android Auto are standard across both.

The Mercedes-Benz GLS-Class counters with panoramic roof and power tailgate that the Mercedes-Benz G-Class does not offer. Which feature set matters more depends on your daily routine and priorities.

Drivetrain

The Mercedes-Benz G-Class uses a Diesel producing 270kW and 750Nm of torque, sent through a automatic to a 4WD layout. It covers the 0-100km/h sprint in 5.8 seconds.

The Mercedes-Benz GLS-Class responds with a Petrol making 270kW and 750Nm, paired to a automatic driving all four wheels. It gets to 100km/h in 6.1 seconds.

Power output is identical on paper, so the difference comes down to tuning, weight distribution, and suspension. In the real-world sprint, the Mercedes-Benz G-Class is 0.3s quicker. For most buyers, the way each car feels day-to-day matters more than outright acceleration.

Space & Comfort

The Mercedes-Benz G-Class measures 4,825mm long on a 2,890mm wheelbase, 390mm shorter than the Mercedes-Benz GLS-Class at 5,215mm (3,135mm wheelbase). The longer wheelbase on the Mercedes-Benz GLS-Class generally means more rear legroom.

Boot space is 480L in the Mercedes-Benz G-Class and 355L in the Mercedes-Benz GLS-Class, giving the Mercedes-Benz G-Class a 125L advantage. The Mercedes-Benz GLS-Class seats 7 vs 5.
