The new BMW M850i Coupe is quickly gaining popularity among tuners all around the world. More and more aftermarket companies target it with fresh options and accessories. Belgian tuner BR-Performance joins their ranks today with a power kit for the model.
The Stage 1 kit is already available for ordering and lends the stock 4.4-liter twin-turbo V8 engine an extra 150 hp / 110 kW along with 100 Nm / 74 lbft of torque. This results in an impressive grand total of 680 hp / 500 kW and 850 Nm / 627 lbft.
The firm did not quote any acceleration-related specs, but you may get a rather clear idea from the following comparison. G-Power’s closest BMW 8-Series upgrade is rated at 670 hp / 493 kW and 890 Nm / 656 lbft of torque. Once applied, the car sprints 0-100 km/h (0-62 mph) in 3.1 seconds and doesn’t hit its speed ceiling until 320 km/h (199 mph). The BMW M850i Coupe should show similar results.
Watch the video to see the tuner measuring the performance of the car on the dynamometer.
