2023 BMW 3 Series M340d

The M340d occupies an interesting position in BMW's line-up — an M Performance model rather than a full M car, but considerably more capable than the badge hierarchy might suggest. The 3.0-litre inline-six diesel, paired with BMW's 48V mild hybrid system, delivers 335bhp and a substantial 700 ft-lb of torque through an eight-speed automatic and xDrive all-wheel drive. That combination dispatches 0-62mph in 4.6 seconds with a 155mph ceiling, while the mild hybrid architecture keeps the drivetrain's efficiency credentials intact for a car of this performance level.

This 2023 car shows 36,621 miles and is finished in grey with a Vernasca leather interior in black with blue stitching — the contrast stitching adding a visual nod to the M Performance identity without being overwrought. The specification includes BMW Live Cockpit Plus, Parking Assistant with front and rear sensors and reversing camera, adaptive LED headlights, and heated front seats. Euro 6 compliant throughout its life.
