Engineers at 9ff have the Bugatti Veyron clearly in their sights with their latest Porsche GT9-R set to enter the record books as the world’s fastest production car with a claimed top speed of around 411 km/h.
As far as production cars go, the GT9-R is about as exclusive as it gets, with only 20 examples expected to see the light and each priced upwards of US$1 million.
Although the car is loosely based on a Porsche 911, its mechanical package has been totally revised. Ditching the 911’s rear-engine layout, 9ff engineers created a custom mid-mounted engine design utilizing the tuner’s twin-turbo 4,0-litre flat-six engine.
The mighty powerplant features titanium con-rods and forged pistons, which were necessary to handle the 823 kW output. A tamer version is also be offered, which will output 725 kW.
Drive is sent to the rear wheels via a conventional 6-speed manual or sequential gearbox. A 5-speed Tiptonic gearbox is also being offered for the less powerful model.
The 911 GT3 body on which it’s based has also been stretched and has had the roof lowered to maximize downforce at high speeds. Thanks to carbon-fibre and Kevlar construction, the entire vehicle weighs in at just 1 325 kgs.
According to 9ff, the GT9-R with 823 kW on board will accelerate from zero to 100 km/h in just 2.9 seconds, pass 300 km/h in 15.8 seconds and top out at 411 km/h. America’s SSC Ultimate Aero TT is the current world land speed record holder with a top speed of 409 km/h, and British automaker Keating claims that its own TKR supercar is capable of reaching 416 km/h – only time will tell.
