2022 BMW X3 M40d

The 2022 BMW X3 M40d is the performance anchor of the X3 diesel range, built around a 3.0-litre straight-six mild hybrid diesel producing 335 bhp and a muscular 700 lb-ft of torque. Channelled through an eight-speed automatic and BMW's xDrive all-wheel-drive system, it covers 0-62 mph in 4.9 seconds — numbers that would embarrass many dedicated sports cars, in a body that swallows five people and their luggage. At 38,361 miles from a single owner, this is an early-life example that hasn't been worked particularly hard.

The specification is thorough. The Technology Package brings a Head-Up Display, and Harman Kardon surround sound elevates the cabin acoustics beyond the standard fit. A Panoramic Glass Sunroof, Parking Assistant Plus, and the Comfort Pack — covering keyless entry and a heated steering wheel — round out a well-considered options list. Inside, Vernasca Leather in Oyster with Grey Stitching gives the interior a premium character; outside, the Grey finish is understated but clean. A factory towbar adds practical flexibility.

The mild hybrid system doesn't transform the M40d's character, but it smooths torque delivery at low revs and aids real-world economy on motorway runs. The M40d occupies a specific niche: M Performance pace without the running costs of a petrol M car, wrapped in an SUV that can function as a genuine daily driver.
