The 9ff GT9 is a super sports car from the German tuning company 9ff based on the Porsche 997 . The GT9 differs from the normal Porsche 911 in the position of the engine. The 911 has a rear engine , the GT9 a mid-engine to distribute the weight more evenly.
The aim of the development of the vehicle was to beat the speed record of 412 km / h of the SSC Ultimate Aero TT for street-legal vehicles from 2007. On April 10, 2008, two independently working GPS devices measured the top speed of the GT9 at 409 km / h. In later top-speed drives, the 824 kW (1120 PS) 9ff GT9-R with 414 km / h achieved the highest speed ever measured in a street-legal vehicle. In order to achieve this speed, the entire vehicle was heavily modified. For example, the roof has been lowered and the wheelbase has been extended. In 2012 the 1029 kW (1400 PS) 9ff GT9 Vmax reached 437 km / h.
