With the 4.4-liter, twin-turbo V8 producing 523 HP and 750 Nm of torque, the standard BMW M850i xDrive can mix it with some pretty serious machinery straight out of the factory.


However, Dahler has unlocked even more potential, upping the engine’s output to 627 HP and 850 Nm of torque. This places it right above the new M8 Competition, which enjoys 616 HP and 750 Nm of torque, and does the 0-100 km/h in 3.2 seconds, half a second faster than the stock M850i.

An even more neck-snapping upgrade is in the works at Dahler, who can also inject other versions of the modern-day 8-Series with more power. For the 840i, the output increases from 335 hp and 500 Nm of torque, to 402 hp and 610 Nm of torque. The diesel-powered 840d can churn out 375 hp and 800 Nm, up 59 hp and 120 Nm.


You could also spend more money on other parts that will slightly boost the visual appeal of your German grand tourer. The Swiss tuner offers a front lip spoiler, lowering spring set, stainless steel exhaust system with silencer and 21-inch CDC1 Counter wheels wrapped in Michelin tires. Coming soon are the coilover kit and DDC Plug&Play that will make the car even more agile.
