G-Power has just released its upgrade packages for the BMW M8 and M8 Competition models. As expected, they’re wild. As standard, the range-topping M8 Competition’s 4.4-liter twin-turbocharged V8 engine is good for 617 hp, more than enough for most but nothing compared to what G-Power has cooked up in the past. Three different power levels are offered up by G-Power.

The first package includes nothing more than software tweaks and results in 720 hp and 850 Nm of torque. One step up in the range takes customers to the ‘stage 2’ kit that combines software tuning with downpipes and sports catalytic converters, good for 770 hp and 930 Nm of torque.


Those after the most performance possible then have the option of the flagship upgrade that’s rated at a cool 820 hp and 1,000 Nm of torque. This package includes larger turbocharger compressor wheels, software tweaks, and the option of aftermarket downpipes, sports catalytic converters, and a titanium exhaust system with carbon fiber tips.

Unlike many other aftermarket manufacturers that pair their engine modifications with dramatic exterior changes, M8 owners who deal with G-Power can keep their cars looking completely stock. With that being said, some minor tweaks are available, including G-Power branding as well as a set of special 21-inch Hurricane RR forged wheels with a black diamond-cut finish. It shouldn’t be too long before the first videos of G-Power BMW M8s start to hit the web. We’re expecting to see supercar-levels of performance.
