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 CLA Coupe

The Mercedes CLA Coupe cuts a rakish silhouette that blends sporty coupe lines with everyday practicality, giving style-minded buyers a premium image without shouting. Inside it feels more luxurious than its size suggests, with a slick cabin, intuitive tech and a composed ride — the kind of car that parties in the city and still shows up polished on Sunday morning.
