Driving experience

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.
