G-Power is well known for their ridiculously powerful E63/64 M6 and E60 M5 models, fitted with their own Superchargers, specifically developed for the S85, 5-liter V10 engine. However, that’s not all they do.
They are also on par with the latest technologies from BMW and took a jab at the S63Tu 4.4-liter V8 twin turbo engine that is currently powering the F10 M5 and F06/12/13 M6 models. What they came up with is certainly impressive.
Their Bi-Tronik II system will take the power output on a M6 Gran Coupe model up to 740 HP and 910 Nm (671 lb-ft) of torque from the standard 560 HP and 680 Nm (501 lb-ft) the car makes, giving it roughly 30 percent more power to play with.
Since the stock model does the 100 km/h (62 mph) sprint in 4.2 seconds, imagine what this car is capable of. They drastic increase in performance is due to a new ECU map, new downpipes and a completely fresh titanium exhaust with 100mm tailpipes. Apart from the bone crushing torque, you also get a new sound that is absolutely crazy, making the stock version completely obsolete. Check it out in the video below!
