The BMW M3 is a masterpiece of German engineering, the best that BMW could turn out using a high-tech engine, transmission, and suspension for unbelievable performance. Yet there's always someone ready to improve on apparent perfection. In this case, it's German tuner G-Power, which supercharged the current M3 to make it the most powerful version currently available.
The modified M3, dubbed the G-Power M3 Tornado RS, hits 62 mph in 3.7 seconds, about a second faster than a standard M3, and boasts a top speed of 205 mph.
G-Power, which has previously fitted its supercharger technology to the BMW M5 and M6, modified the current M3 to produce 720 horsepower and 516 pound-feet of torque. That is more than 300 horsepower over the standard M3's output.
Starting with the M3's 4-liter V-8, G-Power replaced the pistons and crankshaft, then fitted the supercharger over the top. This supercharger forces air into the induction system, the high pressure leading to stronger explosions in the cylinders.
G-Power also offers a carbon-fiber version of the airbox for the supercharger, weighing 18 pounds less than its aluminum variant. G-Power modifies the engine control software for the supercharger, and has a package of carbon-fiber aerodynamic body components.
G-Power can modify a current-generation BMW M3 with its supercharger kit for $47,445 at current exchange rates, but you will have to get your car to Germany first.
