Following a preview late last year, G-Power has officially unveiled their new tuning program for the BMW M5 (F10).

First and foremost, the model benefits from a Bi-Tronik III package which enables the twin-turbo 4.4-liter V8 engine to produce 640 PS (471 kW / 631 hp) and 777 Nm (573 lb-ft) of torque - an increase of 80 PS (59 kW / 79 hp) and 97 Nm (72 lb-ft). This allows the car to rocket from 0-100 km/h in 3.9 seconds, 0-200 km/h in 11.9 seconds and on to a top speed in excess of 310 km/h (193 mph).

The car can also be equipped with an adjustable coil-over suspension, a sports exhaust system and 21-inch alloy wheels with Michelin Pilot Super Sport tires. Lastly, there's a ceramic braking system with larger pads, metal-coated lines and discs that measure up to 396mm in diameter.
