ABOUT THE 2020 BMW 840I COUPE

The 2020 BMW 840i Coupe is the six-cylinder, rear-wheel-drive version of the revived 8 Series (G15), a two-door grand tourer. It is powered by a 3.0-litre turbocharged inline-six producing 335 hp and 368 lb-ft, with an eight-speed automatic.

New to the range for 2020

BMW brought back the 8 Series name for the 2019 model year, initially only as the V8-powered M850i xDrive. The 840i and 840i xDrive joined the line-up for 2020, giving the coupe a more efficient six-cylinder option. The same year also saw the range expand with the Gran Coupe and the arrival of the M8, making 2020 the year the 8 Series family reached its full breadth.

Grand touring character

The 840i is tuned for comfort and long-distance cruising rather than outright aggression. The inline-six is smooth and quiet, and the rear-drive chassis gives balanced handling. The cabin is plush, with Live Cockpit Professional digital instruments and high-quality materials, but the 2+2 layout means the rear seats are best for children or short journeys. The boot is a reasonable size for weekend luggage.

Buying one today

The B58 engine is generally regarded as one of BMW’s most reliable modern units, though coolant leaks are commonly reported. As with any modern luxury coupe, check that the electronics, driver-assistance sensors and adaptive features all work correctly, and look for even tyre wear.

Rivals

The 840i Coupe competed with the Mercedes-Benz S-Class Coupe, Lexus LC 500, Porsche 911 Carrera and Jaguar F-Type.
