The German tuning house has also unleashed a slew of cosmetic and performance parts for the G80.
German tuning firm G-Power has built a reputation around making the BMW M3 go faster than the manufacturer ever intended it.
The brand's genesis was a V10-powered E46 M3 CSL, and now it's back to tune up the latest M3. This time, G-Power's fettling has led to an M3 Competition with an astounding 720 horsepower and 627 lb-ft of torque.
That's more than even the next-generation M5 will have, and as with most modern cars, surprisingly few parts are needed to obtain the 217-hp bump in power. G-Power also offers parts for the standard G80 M3, which, thanks to different states of tune, offers between 620 hp and 670 hp.
G-Power calls its new creations the G3M BiTurbo, owing to the M3's twin-turbo inline-six engine. In addition to the various ECU tunes for different levels of the M3 lineup, G-Power has announced a host of new performance and aesthetic upgrades to help your G80 look like the 700-hp killing machine it is.
These include two sets of wheels with various finishes. G-Power's Hurricane RR wheels are massive, wearing 285/30R20 rubber at the front and 295/25R21 tires at the rear. The wheels themselves measure 20×9 at the front and 21×10.5 out back.
In addition to the new metal, G-Power has developed a carbon fiber package for some extra visual sauce and weight-saving.
The new carbon fiber bits include a wing mounted to the trunk lid, not the chassis. A carbon fiber splitter and side skirts are also available, in addition to new carbon trim for the front air curtains. Two flavors of carbon fiber are available for the G-Power parts. You can have any of the above in either traditional woven or forged carbon.
The tuning firm will also add some carbon to your M3's new exhaust, with a complete cat-back system and carbon tips available. Finally, two new hoods have been designed to really show off the M3's face. These are available in a wide range of finishes, from naked carbon (again woven or forged) to painted with carbon fiber air vent accents.
