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 GLA

The Mercedes GLA is a compact luxury crossover that brings Mercedes-Benz's refined design and premium cabin materials into a practical, city-friendly package. It combines comfortable ride quality and intuitive tech with poised handling, making it a confident choice for everyday driving and longer journeys.

You have to compare like with like — the GLA should be compared to the Q3, not the Q2 as in your study!
