You can spend a day setting fast laps and then drive this beast home.

G-Power from Germany wants to offer the ultimate M3 for road and track use, but rather than using the latest generation for its hardcore machine, the aftermarket firm starts the earlier E92-generation as the basis for this road-legal corner carver that it calls the M3 GT2 S Hurricane.

The company overhauls the M3’s already impressive standard V8 powertrain. The biggest change is that a long-stroke crankshaft boosts the displacement to 4.5 liters from the stock 4.0 liters. There are also forged components for the pistons and connecting rods. The stronger internals are necessary because G-Power also adds a supercharger that runs at 11.6 psi (0.8 bar). The result of all of this work is 709 horsepower (529 kilowatts) and 479 pound-feet (650 Nm). An limited-slip differential with a separate oil cooler helps make sure all of this grunt gets to the road.

According to G-Power, its higher displacement, supercharged M3 can hit 124 miles per hour (200 kilometers per hour) in 9.8 seconds and reach a top speed of 205 mph (330 kph).

For making the most of the huge output, G-Power installs coilovers with the firm’s own Nürburgring Setup that tunes the ride height and dampers for the Green Hell. Ceramic brake discs slow down this M3 when it’s time to get through the twisty sections of the track. 

G-Power’s M3 doesn’t try to hide its performance capability. A carbon-fiber widebody kit in eye-catching orange covers the 19-inch wheels. The company also replaces the doors and hood with carbon-fiber replacements. When on track, air jacks lift the car quickly for swapping tires quickly.

The company strips the cabin to the bare essentials, including tossing the rear seat. Alcantara covers everything that remains. Rather than the standard gauges, a simple multi-function display sits in the instrument panel. For safety, a roll cage protects occupants on the track, and if things go really poorly then there’s a fire suppression system, too.
