The BMW M Performance model that will be available from launch provides a particularly impressive demonstration of the new BMW 8-Series Coupe's sporting essence. Under the bonnet of the BMW M850i xDrive Coupe lies a 390 kW/530 hp V8 engine that has undergone extensive refinement and produces formidable power. It serves up a particularly intense form of the unmistakable power delivery and acoustics of eight-cylinder units and is every bit as captivating and emotionally thrilling as the car it powers. The second engine available at market launch clearly demonstrates the long-distance prowess of the new BMW 8-Series Coupe. The 235 kW/320 hp six-cylinder in-line diesel engine in the BMW 840d xDrive Coupe combines instantaneous pulling power with exemplary efficiency that greatly reduces the number of refuelling stops necessary when touring. Both engines transfer their power to a latest-generation eight-speed Steptronic transmission that boasts a wider gear ratio spread and even sportier gear shifts and can be operated by means of shift paddles on the steering wheel. Completing the all-round package for supreme driving dynamics is the BMW xDrive intelligent all-wheel-drive system, which is also fitted in a newly improved version that has been tuned for this specific model. The rear-wheel bias of the xDrive system and the rear differential lock fitted as standard on the BMW M850i xDrive Coupe ensure maximum agility and precision when the car's sporting capabilities are being put to the test.
