BMW Tuner G-Power's E92 M3 GT2 S Hurricane Packs 710 HP
This M3 allegedly has a top speed of 205 mph.
G-Power has continually done a fantastic job of completely rebuilding BMWs to maximize their performance potential and to transform these already amazing cars into true animals. For G-Power's most recent build, they took a BMW E92 M3, widened it, drastically changed the aerodynamics and completely built out the engine.
According to the short video, G-Power used carbon fiber to build a custom body kit and aerodynamics for improved handling. They then bored out the original 4.0-liter V-8 to 4.5 liters and slapped on a nice supercharger running at 11.6 psi to obtain around 710 horsepower and 479 lb-ft of torque. This allows the heavily modified BMW M3 to launch to 124 mph in just 9.8 seconds, and reportedly tops out at 25 miles per hour. The whole build overall looks extremely clean; that's likely in part thanks to G-Power's in-house CAD system and with testing facilities, which allow them to hash out all the kinks without shipping the car to another company.
The impressive build is called the G-Power M3 GT2 S Hurricane, and it is designed for ClubSport racing.
