About this car
A 2021 M340i xDrive in black, showing 23,459 miles from new. This is BMW's M Performance take on the G20 3 Series — a mild-hybrid 3.0-litre straight-six producing 369 bhp and 500 lb/ft, driving through xDrive all-wheel drive and an eight-speed automatic. The page lists a 155 mph top speed, and BMW's own claimed 0-62 of 4.4 seconds puts it firmly in the territory of cars wearing more serious badges.
Specified with the Visibility Pack (LED and Laser headlights) and the Comfort Pack, plus a heated steering wheel and extended storage. The interior is trimmed in Vernasca leather in black with grey stitching, and equipment extends to BMW's Live Cockpit Professional. A sensible real-world sports saloon with the B58 engine that has become one of BMW's most celebrated modern sixes.
