The 9ff GT9 is a sports car based loosely on the Porsche 911,[1] 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 4.0 litre flat 6 that produces 738 to 1,120 bhp (550 to 835 kW; 748 to 1,136 PS), depending on the configuration.[2] 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 racer) 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 5.2 seconds (from a standing start) to reach 100 km/h (62 mph), and 34.9 seconds to reach 300 km/h (190 mph).[3] The top speed of the original GT9 is 409 km/h (254 mph).[2][4] This was faster than the original Bugatti Veyron, but slower than both the SSC Ultimate Aero TT and the Bugatti Veyron SuperSport.

The interior of the car has been stripped out for lightness, and thus were very basic compared to a standard 911 Turbo. All GT9s had blue leather, square patterned trim, with a roll cage for safety.

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,[4] with all of them already sold.

9ff GT9-R

The 9ff GT9 was replaced by the GT9-R, offering up to 1,120 bhp (840 kW; 1,140 PS). It was designed to take the speed record for a street legal car, with a claimed speed of 414 km/h (257 mph).[2]

It does 0–100 km/h (62 mph) in 2.9s and 0–300 km/h (190 mph) under 16s.[5] As with the original GT9, only a limited number of GT9-Rs were produced and only 20 with the largest engine.[2]

Before the GT9-R's top speed could be independently verified, the Bugatti Veyron Super Sport achieved a record top speed of 431.072 km/h (267.856 mph).

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.[6] This car used the Stage 1 engine, thus producing 738 bhp (550 kW; 748 PS),[7] 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 spoiler, front splitter, and revised air intakes.[8]
