The Mercedes-Benz G-Class stands out with Burmester audio — features our data doesn't list for the Audi Q8. The Audi Q8 counters with panoramic roof, heated front seats, ventilated seats, power tailgate and Bang & Olufsen audio. 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 Audi Q8 responds with a Diesel MHEV making 210kW and 600Nm, paired to a automatic driving all four wheels. It gets to 100km/h in 6.1 seconds.

The Mercedes-Benz G-Class has the clear power advantage at 270kW vs 210kW. In the 0-100 sprint (manufacturer-claimed), 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, 181mm shorter than the Audi Q8 at 5,006mm (2,995mm wheelbase). The longer wheelbase on the Audi Q8 generally means more rear legroom.

For towing, the Audi Q8 leads with a 3,500kg braked capacity vs 3,500kg. That 0kg difference matters if you regularly hitch up.
