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.
Renault Koleos
A relaxed family cruiser rather than a dynamic driver's car, with good visibility. Comfortable and composed for a mid-size SUV, with a soft ride that prioritises long-distance refinement. Steering is light and accurate enough for the size but lacks strong feedback. Body control is adequate, though some examples feel soft over larger bumps. Diesels provide strong low-end torque for motorway use and overtaking. X-Tronic CVT automatics are smooth once under way but can feel sluggish or noisy under hard acceleration. AWD versions add traction in poor conditions but increase weight.
