There are only a handful of cars that can strike fear into the Bugatti Veyron. The Koenigsegg CCX comes close with a top speed of 242.42 mph, and the SSC Aero Twin-Turbo is even faster, hitting a two-way average speed of 255.83 mph and officially taking the crown of world's fastest car back in September. These über-fast supercars will now be looking over their shoulders with the new kid on the block, the 9ff GT9. Based on the Porsche 911 GT3, 9ff stretches the chassis about a foot and chops the roofline for improved aerodynamics. A carbon-kevlar subframe houses a twin-turbo 4.2-liter flat-6 pushing out 987 bhp. Our German is a bit rough, but we can translate enough of Autobild's recent story on the 9ff GT9 to know they achieved ridiculous speeds in the super Porsche at the Papenburg high speed oval in Germany. 409 km/h to be exact, which roughly translates to 253 mph. We're not sure if there is more speed left in the GT9 to top the Bugatti or the SSC, but it's impressive nonetheless.
