Compare the BMW X7 vs Mercedes-Benz GLS
AI generated from our expert reviews
Both of these massive luxury SUVs are proper seven-seaters that can accommodate adults in their rearmost rows without fuss. However, the BMW X7 proves roomier when you have seven people on board. If cargo capacity is your priority, the Mercedes-Benz GLS offers a larger boot in five-seat mode, giving you 890 litres compared to the 750 litres found in the X7. Out on twisty roads, the X7 is enjoyable to drive for a car of its size and weight and handles a bit better than the GLS, though the Mercedes does not embarrass itself. Step inside, and you will struggle to find scratchy plastics in the X7, whereas the GLS disappoints with some scratchy plastics lower down in its cabin and some switches that feel flimsy.
