The German tuner G-Power has increased the power output of the BMW M6 Gran
Coupe to respectable 730 hp and 720 lb-ft (975 Nm) of torque.
The impressive power hike was possible via a custom-made ECU and a reworked exhaust system, which provides a "deep, throaty sound that turns heads" and is 26 lb (12 kg) lighter, according to G-Power. The G-Power exhaust system is available with four titanium or carbon tailpipes with a diameter of 100 mm.
Thanks to these improvements, the M6 Gran Coupe can accelerate to 124 mph (200 km/h) in just 10.5 seconds, while the top speed is more than 186 mph (300 km/h).
Exterior design has been enhanced with 21-inch Hurricane RR wheels wrapped around Michelin 255/30 ZR21 front and 295/25 ZR21 rear tires. Handling is further improved by the height-adjustable G-Power GM6-RS coil-over suspension with nine selectable settings.
The standard breaking system may lose brake force when pushed to the limit, accompanied by a moving braking point, the so called fading effect. To resolve this, the Germans have installed 420mm discs with six-piston calipers at the front that enables a substantially higher brake force than the standard braking system. At and additional cost, a ceramic braking system - weighting 50 percent less - is also offered.
Apart from the modifications that increase power and performance, G-Power also completely reworked the interior of the M6. Accessories such as the ergonomically formed sports steering wheel, instruments in G-Power design, G-Power emblems, soft leather and Alcantara add a sense of exclusivity while a multimedia entertainment system leaves nothing to be desired with its powerful audio system, iPads and an Apple TV.
