The 9ff GT9 is a sports car based loosely on the Porsche 911, built by German tuning company 9ff, founded by Jan Fatthauer. Based on the Porsche 911 (997) GT3; the cars are extensively rebuilt and fitted with a heavily modified 3.6-4.0 litre flat 6 engine that produces 738 to 1,120 bhp (550 to 835 kW; 748 to 1,136 PS), depending on the configuration. One of the major differences from a normal 911 is the positioning of the engine; whilst every 911 throughout Porsche's history (excluding the Porsche 911 GT1 race car) has been rear-engined, the GT9 is mid-engined for better weight distribution.
It takes the 9ff 3.8 seconds (from a rolling start) or 4.2 seconds (from a standing start) to reach 60 mph (97 km/h), and 17.6 seconds to reach 190 mph (310 km/h). The top speed of the original GT9 is 409 km/h (254 mph). This was faster than the original Bugatti Veyron, but slower than both the SSC Ultimate Aero TT and the Bugatti Veyron Super Sport.
The interior of the car has been stripped out for lightness and thus was very basic compared to a standard 911 GT3. All GT9s had blue leather, square-patterned interior trim, with a roll cage for safety. A carbon fibre and Kevlar construction helps further in weight savings.
9ff stated that only 150 GT9s would be produced, and only 20 of those would have the most powerful engine. Prices ranged between £150,000 and £540,000 depending on engine and options, with all of them already sold by the time the car was launched in the market.
9ff GT9-R
The GT9-R was a high performance variant of the GT9, offering up to 1,120 bhp (840 kW; 1,140 PS) from a 4.0L twin-turbocharged flat-6 engine. It was designed to take the speed record for a street legal car from the Bugatti Veyron, with a claimed speed of 420 km/h (260 mph), although this was never tested.
It accelerates from 0–100 km/h (62 mph) in 2.9s and 0–300 km/h (190 mph) in under 16s. Only 20 examples of the GT9-R were produced.
9ff GT9-CS
At the 2011 Essen Motor Show, 9ff brought out the third version of the car, the GT9-CS, built as a one-off. This car used the Stage 1 3.6L twin-turbocharged flat-6 engine, thus producing 738 bhp (550 kW; 748 PS), and was designed specifically as a track-day car. A further 86 kg (190 lb) of weight was removed from the car, and several changes were made - a new rear wing, front splitter, and revised air intakes.
9ff GT9 Vmax
At the 2012 Essen Motor Show, 9ff revealed their new Vmax variant of the GT9 which produced 1,381 hp (1,030 kW; 1,400 PS) and 855 lb-ft (1,160 Nm) of torque from a 4.2-liter twin-turbocharged flat-six. This variant of the GT9 weighed 1,340 kg (2,950 lb) and was said to reach a top speed of 437 km/h (272 mph). At the time of release, this variant cost €895,000.
