Engineers at 9ff have finally accomplished their goal of beating the Bugatti Veyron’s 407km/h (252mph) top speed, with their highly modified GT9 supercar posting a new top speed of 409km/h (254mph) during official testing in Papenburg last month. The world record for the fastest production car, however, is still held by America’s SSC Ultimate Aero TT, which reached a top speed of 411km/h (255mph) last September.
The GT9 may be a production model but available examples are hard to come by as the car will be built in an extremely exclusive run of just 20 examples and each priced at €592,620 ($853,634). Although the GT9 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 4.2L flat-six engine. Peak output stands at 987hp and 964Nm of torque, reports AutoBild.
The 911 GT3 body, on which it’s based, has also been stretched by 300mm and has had the roof lowered by 120mm to maximize downforce at high speeds. Thanks to carbon-fiber and Kevlar construction, the entire vehicle will weigh in at just 1,326kg.

So what? You failed to mention the engine longevity. 9FF engines requires their engines rebuilt in very short mileage increments. Oh and it’s hideous.
It’s especially amazing when you consider that it did that with cardboard wheels.
Ok cardboard wheels suck but you can smoke Veyron
lol, considering veyron weighs atleast a ton more i consider this no particular achievement
Isn’t that exciting?
they say that they had Ditched the porsche engine … so
why the call it a porsche
it is not porsche
