Driving experience

Audi e-tron

Smooth, silent and effortlessly luxurious. The e-tron rides with genuine isolation, steers lightly and accurately, and accelerates strongly from its dual-motor quattro with none of the fuss of a combustion engine. It is heavy, which shows in corners and in real-world range, but the payoff is a hushed, relaxed calm that suits long journeys. Regenerative braking is strong enough for one-pedal driving in traffic. It was the first large electric SUV from Audi, and it drives more like a luxury saloon than a tall, heavy crossover.

BMW X4

More dynamic and refined than the F26. Steering is accurate and well-weighted, body control is good, and the car feels planted and secure with xDrive. It is engaging for a crossover but prioritises composure and refinement over pure sharpness. Adaptive suspension (where fitted) offers a useful range between firm and acceptable comfort. The B58 M40i is the standout: strong, refined, free-revving and characterful with excellent mid-range punch. B48 four-cylinder petrols are smooth and responsive. Diesels (especially the B57 sixes) deliver strong low-end torque and effortless cruising. Overall a stylish, capable crossover that balances road presence, dynamics and everyday usability better than its predecessor.
