ABOUT THE 2020 BMW 840I XDRIVE COUPE
The 2020 BMW 840i xDrive Coupe is the six-cylinder version of the G15 8 Series, a two-door 2+2 grand tourer built in Dingolfing, Germany. It uses the B58 3.0-litre turbocharged inline-six rated at 335 hp and 368 lb-ft (500 Nm), with an eight-speed automatic and xDrive all-wheel drive.
New to the range for 2020
The 8 Series returned for the 2019 model year with the V8-powered M850i xDrive. For 2020 the six-cylinder 840i joined the range in rear-drive and xDrive forms, giving buyers a lighter, more economical way into BMW’s flagship coupe. The same year saw the arrival of the four-door 8 Series Gran Coupe and the M8.
Character
The 840i is tuned as a comfortable long-distance car rather than a sports car, although the inline-six provides ample performance and the lighter engine makes the front end feel more agile than the V8 model. The cabin is driver-focused and richly trimmed, with the latest iDrive and digital instruments. The rear seats are small and best suited to children or extra luggage, but the boot is useful for weekend trips.
Buying one today
The B58 engine is well regarded; coolant leaks and oil filter housing gasket seepage are the most commonly reported issues. Check that infotainment and driver-assistance software is current, inspect large-diameter wheels for kerb damage, and budget for performance tyres.
Rivals
The 840i xDrive competed with the Lexus LC 500, the Mercedes-Benz S-Class Coupe and the Porsche 911 Carrera 4.
