For the BMW M3, G-Power has a new package that significantly boosts power over stock figures. Customers of G-Power can choose from three power kits to increase the output of the 3.0-liter inline-six engine to the required level of power.
In addition, G-Power unveils a new, more aggressive look that features a carbon-fiber package that includes a new bumper splitter, sportier side skirts, and G-Dynamic Power's fixed rear wing.
Currently, Hurricane RR forged rims and Hurricane RS wheels are the two-wheel options. Both sets have 285/30 R20 and 295/25 R21 tires and are available in the same front and rear sizes of 9x20 inches and 10.5 inches.
The S58 twin-turbocharged engine from the base vehicle is retained by G3M Bi-Turbo, but its OEM software is changed out for custom code. The 3.0 L6 now produces up to 720 horsepower and 850 Nm of torque in the top-of-the-line version thanks to a new exhaust system and other minor hardware upgrades. The same hardware is used by less potent 670-hp and 620-hp variations, which have a different ECU.
Recently, G-Power also unveiled a tuning package for the M340i if you're looking for a fast-modified BMW with a long roof. The fast estate can be tuned to produce up to 510 horsepower and 690 pound-feet of torque, matching the output of an M3 sedan or M4 coupe when equipped with the GP-510 package.
