When G-Power released the first M6 Bi-Tronic III kit , we were rather impressed by the stunning 640 horsepower and 573 pound-feet of torque the tuner was able so milk from the 4.4-liter V-8 engine. Well, color us astounded, as G-Force went right back into the garage and churned on the Bi-Tronic-III V2 kit for the F13 M6 that makes this one of the fastest and most powerful M6 models on Earth.
G-Power added in a new ECU tune and a high-flow exhaust system to extract 710 horsepower between 6,000 and 7,000 rpm, and 656 pound-feet of torque at 4,800 rpm from the fire-breathing BMW V-8. That’s an unthinkable 150-horsepower and 156 pound-feet gain over the already awesome base M6. With this mammoth amount of power in tow, the M6 Bi-Tronic III sprints to 200 km/h (124 mph) in just 10.8 seconds and hits a top speed of 186 mph — a 31 mph gain. Unfortunately, G-Power did not make light of its 0-to-60 mph time, but we’re sure it is far better than the stock 4.1 seconds — likely, it is around 3.5 seconds (0.3 seconds faster than the original Bi-Tronic III M6).
G-Power went to great lengths to also enhance the handling, braking and look of the M6 with additional components. Keeping the M6 glued to the road are 21-inch G-Power Hurricane forged wheels with 265/30 Z-Rated Michelin tires up front and super-wide 305/25 Z-rated Michelin rubber out back. Making sure the body roll is minimal and that maximum rubber touches the road is the GM6-RS G-Power coil-over suspension
G-Power also added in a ceramic braking package that reduces unsprung weight and brake fade for optimal stopping power without negatively affecting the car’s handling.
