G-Power has just unveiled its modified BMW M850i and while it’s no M8, it does have the specs fitting of a car with the M badge. Normally, the BMW M850i pumps out 523 hp and 750 Nm of torque from its 4.4-liter twin-turbocharged V8 engine. For most people, that’s more than enough grunt. For G-Power, it’s comes short.

The famous German tuning company has outfitted the BMW with new performance engine software and fitted a set of stainless steel downpipes with 200-cell sport catalytic converters. The car now pumps out 661 hp and 890 Nm of torque and can, therefore, accelerate to 100 km/h in a rapid 3.1 seconds and reach an approximate top speed of 320 km/h. The horsepower, torque, and acceleration numbers of G-Power’s M850i will put the car one step ahead of both the upcoming BMW M8 and M8 Competition.


The M850i doesn’t enjoy any mechanical upgrades other than those previously mentioned. That means its chassis, suspension, and braking components are all identical to standard M850i models. We’ll have to wait and see what chassis changes will be applied to the impending M models.

G-Power has priced the new engine software at US$ 2831 while the new downpipes and catalytic converters cost US$ 4742. Customers wanting to unlock the vehicle’s full top speed potential need to hand over an additional US$ 500 to have the limiter removed. The only visual alteration offered by G-Power for the M850i are a set of unique 21-inch wheels. Measuring 9 inches wide at the front and 10.5 inches at the rear, they are priced at US$ 8,577.
