9ff reveals even more bonkers GT9-R - is this the world's fastest production car?

Bonkers is a relative term, when you think about it. Case in point: the 9ff GT9. With 973 horsepower and a 409 km/h top speed – that's 254 mph, friends – this was already one bonkers supercar. And then 9ff comes along with the GT9-R, an even faster version with – wait for it – 1120 horsepower and a claimed 414 km/h (257 mph) top speed. That's enough to outgun the 412 km/h (256 mph) record set by the SSC Ultimate Aero TT to claim the top-speed crown. That's right: pending outside verification at least, this is the world's fastest car. On the way, it'll hit 100 km/h (62 mph) in 2.9 seconds, 200 km/h (124 mph) in 7.4 and 300 (186 mph) in 14.9. Right, bonkers.

Although – like 9ff's tuner cars – the GT9-R is loosely based on a Porsche 911, it only bears what could barely be described as a passing resemblance. Just about the entire thing is built from scratch, with a 4.0-liter boxer six all but completely rebuilt.

Only twenty examples of the range-topping GT9-R will be offered, although the *ahem* lesser versions with 750 or 987 horsepower are also available, each built to order to the customer's specifications. We're just afraid to ask how much many euros that entails, especially when the existing GT9 went for half a million. Details in the press release after the jump and photos in the gallery below.
