2023 BMW X4 M40d

The X4 M40d sits at the top of the standard X4 range, and this 2023 example makes a strong case for the diesel performance crossover. Finished in Frozen Marina Bay Blue Metallic — a distinctive matt-effect paint that suits the X4's angular bodywork — it has covered 32,452 miles from new with a single keeper, which is well below average for the age.

The 3.0-litre inline-six mild hybrid diesel produces 335bhp and a substantial 700lb-ft of torque, with xDrive all-wheel drive putting it to the road. The 4.9-second 0-62 time is only part of the story — the torque delivery is immediate and linear in a way that makes this genuinely fast in everyday driving. M Sport brakes with red calipers add visual and functional credibility, and the MHT system provides a useful efficiency buffer at lower speeds.

The options list is well chosen: the Technology Package covers Head-Up Display and wireless Apple CarPlay, Harman Kardon Surround Sound handles audio, and the interior is trimmed in Vernasca leather with grey contrast stitching. Shadowline high-gloss black roof rails and an electric towbar complete a spec that balances performance intent with real-world practicality.
