Driving experience
BMW X1
Confident, refined and remarkably car-like for a compact crossover. Steering is quick and accurate, body control composed, and the X1 feels light and easy to place. The transverse UKL2 platform swaps the old E84’s rear-drive character for front-drive agility and more space; sDrive stays nimble, xDrive adds wet-weather traction. Comfort depends on spec: supple on standard springs and sensible wheels, firmer and choppier on M Sport and run-flats. The B48 20i is the pick, smooth and willing; the B47 diesels pull strongly and stay hushed. Overall a polished small SUV that drives like a raised hatch, not a soft-roader.
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.
