G-Power has upgraded its power boost kit developed for the BMW M6 Coupe F13.
The G-Power Bi-Tronik III package is now in its second version and has lifted output of the twin-turbo V8 4.4-liter from stock 560 HP (412 kW) and 680 Nm (501 lb-ft) to 710 HP (522 kW) and 890 Nm (656 lb-ft). The first version came with a bump in output to 640 HP (471 kW) and 777 Nm (573 lb-ft).
To reach this impressive figure G-Power remapped the ECU and installed a new exhaust system with titanium link pipes which is 12 kg (26.4 lbs) lighter than the stock exhaust. The tuner is offering this exhaust system with four titanium or carbon 100mm tailpipes.
As a result of these upgrades, the car will do 0-124 mph (0-200 km/h) in just 10.8 seconds before reaching a top speed of more than 186 mph (300 km/h).
The modified M6 Coupe F13 rides on 21-inch HURRICANE forged wheels shod in Michelin 265/30 ZR1 front and 305/25 ZR21 rear tires. G-Power also installed a height-adjustable, coilover suspension with nine selectable settings. The aftermarket specialist is offering an uprated braking system with 420mm front discs, while optionally available are ceramic discs which reduce unsprung mass by 50 percent in comparison to steel brake discs.
The power boost is available for 17,985 EUR while for an extra 14,460 EUR you can get the ceramic braking system. The wheels + tires combo costs 8,325 EUR and the coilover suspension is an additional 2,179 EUR.
