After proving in May that its GT9 supercar could run with the world's fastest supercars by topping out at 409 km/h at the Papenburg oval, 9ff is offering a limited production run of twenty cars. Loosely based on a Porsche 911 GT3, each GT9 comes with a heavily modified twin-turbo 3.6-liter flat-six producing 973 horsepower and 711 lb-ft of torque. Other unique items include a chopped roof line, integrated tubular roll cage, six-speed sequential transmission, an adjustable suspension system, and special Continental Vmax tires good for 410 km/h. The price? The GT9 starts at €498,000. What's interesting is that the press release issued by 9ff declares the GT9 as the world's fastest road car, saying it "breaks the new Vmax world record for road-going vehicles", completely ignoring the SSC's two-way top speed run that averaged 255.83 mph, or 411.72 km/h. Yes, fast enough to beat the Veyron, but not quite enough to take the top spot.

[Souce: 9ff]


Graduate engineer Jan Fatthauer, creator and also test pilot of the 9ff proprietary development GT9, accelerates and speeds up from the full banked corner on the Papenburg oval course. Accompanied by a sound spectacle of automobile top class, the 964 Newton metres torque push down on the asphalt and vehemently thrust the car forward. At the end of the four kilometre long straight, the display of the satellite-supported time measurement shows an incredible 409 km/h. With such a result, the 9ff GT9 does not only becomes a member in the elitist 400km/h-Club, no, it even takes the first place and also breaks the new Vmax world record for road-going vehicles.

The source of power
Even as impressive as the maximum speed are the acceleration values of the rear-wheel driven car. It accelerates to 100 km/h in only 3.4 seconds, to 200km/h in only 8.2 seconds and the digital display of the instrument panel shows the 300 km/h in unbelievable 16.4 seconds. The source of power for this overwhelming power is a modified motor from the Porsche 996 Turbo. The water-cooled 6-cylinder horizontally opposed engine with 4 litres cubic capacity and dry sump is equipped with two exhaust twin turbo chargers, titanium connecting rods, forged pistons and a 24 carat hard gold plated induction plate. Thereby, the high-tech aggregate achieves sensational 987 PS / 726 kW at 7,850 r.p.m. The maximum torque of 964 Nm is reached at 5,970 r.p.m.

Custom-made drive technology
9ff offers an alternative to the stationary rear 6-speed transmission, a sequential race transmission. For both models, the transmissions are assembled according to the customer preference.

Guarantee for driving pleasure, comfort and safety
Of course, when developing the 9ff GT9, we put the highest emphasis on driving dynamics and safety. The chassis was equipped with state of the art technology components from motor sports. Electronically adjustable aluminium shock absorbers in connection with double springs at the McPherson front axle and horizontal push-rods at the 5-steering rear axle guarantee an ideal road grip. 9ff uses tyres by its technology partner Continental which ensure a perfect grip and traction. Selected Continental Vmax tyres in connection with ultra-light three-part forged wheels are approved up to a speed of 410 km/h and are therefore perfect for the requirements of such a high-speed car. 9ff uses the wheel-tyre combination with the dimensions 8.5 x 19 with 235/ZR 19 at the front and 11.5 x 19 with 325/30 ZR 19 at the back.

An opulently dimensioned sport brake system provides excellent deceleration values. Ceramic brake discs measuring 380 mm (front) and 350 mm (back) are sandwiched by the front 6- and rear 4-piston system. Special brake pads and an individually engineered race-ABS complete the system.

A breathtaking styling is the result of design and function
A perfect surface quality and a custom-made finish are the hallmarks of the lift-reducing GT9 car design. No dazzler, but a conclusive concept full of technical finesse and dressed in a breathtaking silhouette. For maximum crash safety, 9ff combines the Porsche GT3 front vehicle with a tubular steel-grid and developed a chassis made of very strong carbon- and Kevlar fibre. The compact under-body casing with its integrated rear diffuser generates additional output and renders stability at high speeds. The main feature of the 9ff GT9 is its low height of only 1,180 mm which underlines the striking racy impression. Moreover, its small frontal area is an important criterion for reaching speeds over 400 km/h.

Engineered design without limits
What ever makes your heart beats faster, we have it. Embroidered car mats, full-leather interior, everything produced with skilled craftsmanship. Whether you like it noble or sportive - 9ff offers has everything for any taste.

The 9ff Fahrzeugtechnik GmbH produces a limited edition of 20 GT9 cars at the company location in Dortmund. The super race car by this specialist manufacturer for tuned Porsche cars is offered from 498,000 euros.

      W T F happened to the rear wheel???
      • 7 Years Ago
      It becomes painfully obvious sometimes here that it's simply too much effort for you to translate euros and kilometers into dollars and miles.
      • 7 Years Ago
      The 9ff GT9 is f...... amazing! And since the guys from SCC never got their record confirmed - the 9ff is ACTUALLY the fastest - sorry guys... Do yourself a favor and read the article about the GT9 in AutoBild - Sportscars.

      Here's a pat on the back for second place, 9ff.

        the 9ff did the run with two people in the car... and it drove the 200km way to the Papenburg test track on own wheels and back and did the 254mph run several times at the same day with car journalists on the codriver seat to give them a impression of toping 250mph ...

        The 9ff GT9 is the fastest car in the world tested with two people on board :p

      Whoa, looks much cooler than most Porsche's, very awesome.
      • 7 Years Ago
      They need to put these cars on the salt where real records are broken. Bonneville and Black Rock both have plenty of street cars on them and these should be there too!

      If only I were rich.

      How is it possible for a 3.6L flat-six to make 973HP?!?
        • 7 Years Ago
        Well, that's just slightly more feasible than the Audi MTM Bimoto wringing 510 hp out of a pair of turbo'd 1.8 liter 4-bangers. EACH. Remember that thing? :)


        John Doe, I think Autoblog said 3.6 liters because 9ff started with the blown 3.6 liter from a 996 911 Turbo, but they've obviously bored it out a bit. I'm quite certain that 4 liters is the correct spec for this car.
        • 7 Years Ago
        Oh. I see the press release says it's a 4L, but autoblog says it's a 3.6L. Typo?
        • 7 Years Ago
        It's a four litre...
        Still impressive of course.
      • 7 Years Ago
      Amazing car, faster than a Veyron and more brutal, and for the price of 1 Veyron, you can buy two of these
      • 7 Years Ago
      Looks better than anything Porsche makes now!
