9ff is an esteemed Porsche tuning unit from Germany founded by Jan Fatthauer of Zuffenhausen who set out to build the fastest car in the world. Of course.. we all do don't we?

After requiring an Automotive Engineering degree he worked for several tuners before starting out on his own. Back in January 2004, Jan reached 372km/h in his 9ff T6 at the Nardo track and returned back to the track in December that same year driving up to 388km/h in his 9ff V400.

Fast forward to 2012, the team at 9ff has created a potent auto vehicle - the GT9 Vmax - a 1,381bhp German monster with a top speed of 437km/h. the GT9 Vmax is based on 997-model Porsche 911 and weighs just 1339kg.

The carbon fibre clad GT9 Vmax is powered by a twin-turbo'd 4.2-litre flat-six, with a earlier reported high figure of 1,381bhp and 1,157Nm of torque mated to a six-speed gearbox. To save weight the windows are made from polycarbonate and aerodynamic efficiency in increased through faired rear wheels.

Light weight and intense amount of power propels the GT9 Vmax to 100km/h in 3.1 seconds and it takes just 6.8 seconds to hit roughly 200km/h and 300km/h in just 13 seconds.
