The iconic BMW M8 coupe is about to say goodbye, but before it's gone, German tuner G-Power is giving it a powerful power boost. The original Competition trim has 617 horsepower, but if that's not enough, the 900-horsepower G8M Hurricane RR is for you. For those who need a more practical vehicle, the same power boost can also be had in the four-door M8 Gran Coupe.
To achieve this kind of power from BMW's twin-turbocharged 4.4-liter V-8 engine, it's not a simple boost adjustment. G-Power modified the pistons and connecting rods using forged components. The turbochargers were not replaced but rebuilt with larger turbine wheels in modified housings. Additionally, they upgraded the intercoolers and created a new exhaust system, all done in-house. According to G-Power, the G8M can reach a speed of 205 mph after the computer reflash.
There is no mention of any changes to the M8's suspension or brake systems. In factory settings, the M8 has 15.7-inch front brakes with a carbon ceramic option, but G-Power fitted 21-inch wheels with 285/30-series tires up front and wider 295s in back. The M8's eight-speed automatic transmission and xDrive all-wheel-drive system are unchanged, and are said to be able to support 774 pound-feet of torque.
Visual upgrades are also included in the package. G-Power added a large rear wing, carbon-fiber grille, new hood, and other bodywork components available upon client request.
When asked how much it will cost, G-Power did not release a price. But since the M8 Gran Coupe starts at $140,000 in the US, the 900-hp version must be very expensive. Plus, getting this modded car outside of Europe can be a challenge.
