German tuner adds its own G-POWER SK II "Sporty Drive" supercharger kit and an all-titanium exhaust system for an extra 185 PS / 136 kW and 190 Nm of torque.

German tuner G-Power has finally unveiled details on its version of the BMW M3 GTS.

G-Power has fitted its own specially developed supercharger system to the 4.4 liter V8 that adds more than a third more power to the M3 GTS. The G-POWER SK II "Sporty Drive" supercharger kit uses ASA superchargers that help bring total output to 635 PS (467 kW / 626 bhp) and 630 Nm (465 lb-ft) of torque - up from the series 450 PS (331 kW / 444 bhp) and 440 Nm (325 lb-ft).

The performance also gets a boost from the in-house all-titanium exhaust system and a new ECU software setup that makes for the impressive numbers which follow.

The 0 to 100 km/h sprint takes just 4.2 seconds while the car makes it to 200 km/h (124 mph) in 11.9 seconds. Top speed is 323 km/h (200.7 mph).

G-Power leaves the suspension and body kit from the standard M3 GTS intact, believing it was just a lack horsepower that was holding the racer back.

The G-POWER SK II "Sporty Drive" supercharger system costs €23,500, not including taxes or installation.
