A slightly inflated price relative to the equipment included in this car.

Comfortable, but feels a bit firmer (over small bumps) than the Q5. You can tell the car has some heft!! The electric power — 388 PS / 285 kW BEV — is incredible. The battery drops pretty quickly if you push the beast a little. The advertised 600 km range is generous on paper; expect more like 500, or even 450 in winter. The onboard technology is surprising and pushed to the extreme. After trying it, it's hard to go back to a non-electric model.

Mercedes GLS

The GLS — usually just called the GLS — is Mercedes' flagship SUV, wrapping limousine-like comfort and commanding road presence into a smart, family-ready package. It pampers occupants with a hushed cabin, premium materials and intuitive tech, while still managing to feel confident and a little indulgent on the daily commute.
