2021 BMW 8 Series M850i xDrive

The M850i is the V8 flagship of BMW's 8 Series line, pairing a 4.4-litre twin-turbocharged petrol engine producing 523 bhp and 750 lb-ft with an eight-speed Steptronic automatic and xDrive all-wheel drive. It is a grand tourer first, but the numbers are serious: BMW quotes 0-62mph in 3.8 seconds, with top speed limited to 155mph.

This 2021 (71-plate) coupe has covered 35,657 miles and is finished in blue over BMW Individual full Merino leather in black, with an Alcantara Anthracite headlining. The optional extras include the M Carbon Exterior Package, a carbon roof, and 20-inch M Light Y-Spoke 728M alloys in Jet Black with performance tyres. The Technology Package brings adaptive cruise control and a 360-degree camera, while the Visibility Pack adds laser headlights. The Premium Package includes a heated steering wheel, and further touches include BMW Individual high-gloss Shadowline trim, CraftedClarity glass applications and sun protection glazing.

The carbon roof lowers the centre of gravity and saves weight, which suits the car's blend of long-distance comfort and strong V8 pace. It is a fast, well-equipped alternative to the M8 for buyers who want most of the performance with a calmer character.
