After two months of work, G-Power has officially unveiled their Stage 1 package for the BMW M5 (F10).
The German tuner offers a ceramic braking system with 400 mm rotors for the front axle, an adjustable coil-over suspension, a sports exhaust system and a set of 21-inch forged three-piece Silverstone RS wheels.
Most importantly, the twin-turbo 4.4-liter V8 gets an upgrade to 640 hp and 777 Nm of torque - an increase of 80 hp and 97 Nm. This allows the car to accelerate from 0-100 km/h in 3.9 seconds, 0-200 km/h in 11.9 seconds and hit a top speed of more than 310 km/h.
