Time for some turbocharged fun!
It’s hard for G-Power to bid farewell to the BMW S85 V-10 models like the M5 and M6 that the German tuner had pushed to their limits with supercharger systems and even alternative fuel upgrades. Now they are welcoming the new S63 family of twin-turbocharged V-8s used in the new F10 BMW M5 and F12/13 M6 models with some new tuning programs, the latest of which is for the mighty M6. Although it may be a slight makeover in terms of upgrades, history shows that this is just the beginning to bigger and better things for the M6 from G-Power.
Starting things off is a fresh tune for the new S63B44TU twin-turbocharged 4.4-liter V-8 in the BMW M6 that’s been specially-designed and custom-tailored for each individual engine. The engineering team pulled from their vast experience with superchargers to create a software program that altered the fuel and ignition timing along with the boost pressure. But the G-Power team didn’t just leave it at that; to ensure maximum reliability, they altered the tune so that torque is limited between gearshifts in order to reduce stress on the transmission and other components. In addition to the tune, the engine becomes a bit more vocal thanks to a new in-house titanium exhaust system with new link pipes with resonators starting from the downpipe catalytic converters and four different 100 mm titanium or Carbon tailpipes. The exhaust is 26.5 lbs. (12 kg) lighter than its factory counterpart and provides a deep and enjoyable rumble at the push of the throttle.
Those two modifications make the stock 552 horsepower and 502 lb-ft. of torque seem a bit boring, as output rises all the way up to 640 horsepower and 573 lb-ft. of torque. The increase in power is good for an even more exciting 0-62 mph time of just 3.8 seconds compared to the factory 4.2 seconds and a top speed of 196 mph (315 km/h).
But that’s not the end of things. In order to control all of that power, G-Power upgraded a few other parts of the chassis, starting with the suspension. The factory setup was modified by a new GM6-RS coilover suspension with nine-way adjustable bound and rebound along with variable height to allow for the perfect configuration for a given track. The factory brakes were then upgraded at the front axle with a new set of six-piston, 420 mm ceramic brakes with metal-coated lines that reduce weight by 50-percent over steel units, dissipate heat more efficiently, and reduce fade.
The final touch is where the rubber meets the road. The BMW M6 was outfitted with a set of G-Power Silverstone RS forged wheels with a split-spoke design in a 21-inch diameter at the front and rear. New 265/30 ZR 21 front and 305/25 ZR 21 rear Michelin Pilot Sport tires were fitted to each wheel to achieve even greater amounts of grip.
The new G-Power BMW M6 upgrade program is currently available as a complete package or as individual modifications. The wheel and tire setup is priced at 8,325 Euros, the ceramic brakes at 14,460.50 Euros, and the titanium exhaust system for 5,985.71 Euros. The engine tune starts at 5,200 Euros and includes individual tuning for the customer’s car.
