9ff GT9-R – Click above for high-res image gallery

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.

best technology for the best performance
... consistent in every detail

The GT9-R is limited on 20 pieces worldwide. Each car which leaves our company after several tests will be unique, like their owners. The customer has the choice to create his GT9-R on his own preferences. The Exterieur Design is adjustable to the performance of the car. It is available as a
topspeed performance or a track performance model. We offer several aerodynamic solutions for matching the performance of the car best to the customer.

The engine is available in 3 stages. Each stage has its own advantage. So the driver can learn how to handle the GT9-R step by step without risk. The engine stages are upgradeable anytime.

Mid Engine Concept
4.0 - 6 cylinder Boxer engine
0-100 km/h in 2.9 seconds
0-300 km/h in 15,8 seconds
Topspeed 414 km/h
GT9-R 1120 HP

... in each aspect
In the world of the supersportcars the GT9-R is a class of its own.
His powerful exterieur has been designed for maximum performance on the
racetracks all over the world and also on the street. Diving emotions like in no other
car before.

... individual like the customer
The GT9-R starts with a 750 HP kit which is good for a maximum speed of 380 kmph and an acceleration time from 0-300 in 20 seconds and optimized for track performance. The se-cond stage of 987 HP has build for track performance and also a Highspeed racer which reaches 409 kmph and accelerates in 17 seconds from 0-300 kmph. The third stage is the
ultimate driving machine. With its 1120 HP it hits a Topspeed of 414 kmph and goes from standing to 300 in only 15.8 seconds.

... streetlegal
Best technology for the best performance. The GT9-R is a lightweight car which has only one target - best performance in every situation. A lightweight construction combined with an engine which contains the know how of 7 years in developing turbo engines gives the car the
ability to be the most exclusive streetlegal car in the world.

The gear can be ordered in 3 different types
• 6 speed manual
• 6 speed sequential
• 5 speed Tiptronic (only in combination with 750 HP)

      I have a problem with this car solely due to the pure oneupsmanship here. It's faster by ONE mile per hour. I know...faster is faster. But still...I'd like to see a little more.
        • 5 Years Ago
        Agreed. But at the same time, after a certain point, the difficulty of getting each extra MPH gets exponentially greater.
      • 5 Years Ago
      That's a cool car. Funny how articles like this bring the "Veyron Defenders" out of the woodwork. "Ohh the Veyron is heavy, so it's so much more impressive that it's almost the fastest car in the world - if it wasn't a Veyron, it'd be faster!!!". Fact 1: Weight doesn't really affect top speed. Fact 2: it doesn't matter, and you brought up the whole Veyron thing.

      I wonder if this would go quicker with the wheel covers it used to have.
      • 5 Years Ago
      I hardly consider this to be a production car...

        Thats a myth in the english speaking car press that the GT9 is based on a 911... the only chassie part taken from a 996 GT3 is the frontal crash structur to get around world wide crash tests. The GT9 has a completely 9ff developt tube frame chassie. with the frontal crash structur of the GT3 bolted to it.


        there is no Porsche chassie under the 9ff GT9...
        • 5 Years Ago
        Weight has little to do with a vehicle's top speed. It's all about aerodynamics and power.
        • 5 Years Ago
        Totally agreed.

        I love porsche, but this is not one. it is done by someone that is truly good at modifiying them to be monsters so i guess they know porsche and thus their hyper-car is loosely based off a porsche.

        its not a porsche.

        Though that much power out of a H6 is amazing.

        Though the numbers dont match up weight wise. how much does this weigh and how much does a veyron weigh? vs. top speed...
      • 5 Years Ago
      That much power coming from that small an engine cannot possibly bode well. Even if it is boosted beyond recognition (which it doesn't seem like given the 0-60 times) it seems like it's wired to blow if you drive over a toothpick.
        • 5 Years Ago
        not sure if it is THAT tightly wound. Porsche has a history of getting high power numbers out of their race cars.

        But it would be easier to achieve this end with different means... like more displacement, and less forced pressure.

        A lightly pressurized flat 12, perhaps?

        I've always wondered why Porsche hasn't done flat 8s again, after briefly working with them in race cars in the 70s/80s era... but weight distribution aft of the rear axle, and rear overhang and engine bay restriction are most likely the reasons they never put one into a road-going 911.

        I always kind of wondered why the Carrera GT went with a V-engine configuration and 10 cylinders... rather than flat, with 8 or 12 cylinders, with or without turbos. But then I also wondered why it wasn't a fixed-roof coupe, also...
      • 5 Years Ago
      It was the same story with the Veyron. They wanted to make it achieve a certain speed (400+ or something) and when they saw that with all that power it still wasn't close, they started playing with aerodynamics and got what they wanted from there instead. That's why it hunkers down and the spoiler retracts when it's in top speed mode or whatever that's called.
      • 5 Years Ago
      Ummm yes, AIR

      As much as I love the idea of a Porsche being the fastest production vehicle, it just makes makes me love the Bugatti that much more. this thing looks gutted, uncomfortable, and ridiculous, which is a combination I love, but only on occasion. this is not a daily driver, nor will it ever be. You'll put on your fire retardant suit, helmet, HANS device, and get in. If I ever had the money to buy this, id pass, simply because Id rather buy a Bugatti. id put on my shorts and t-shirt, and drive it a whole 4mph slower.

      With that being said, congratulations 9ff, on the fastest production car. You never fail when it comes to making my jaw break from colliding with the ground. but I fear you've gotten into a battle with a beast to big to handle. If Bugatti really cared, I think they can make alot more then just 1001hp from a w16 quad turbo'ed engine. Enjoy the title in all its glory...for now
        • 5 Years Ago
        The reason Bugatti uses a 8L W16 engine to make 1000+ hp is that it will last much longer than a 4L H6 making 1000+ hp.
        • 5 Years Ago
        The first thing I thought when I looked at the photos was "sure it can go faster, but this thing is hideous compared to the Veyron". The Veyron is essentially the perfect car: luxurious, gorgeous, unique, and fast. It seems like most of the competitors for the title of "worlds fastest production car" are only a couple of those are once, never all of them.
      • 5 Years Ago
      Technically bloody amazing.

      Stylistically, not so much... but that is not what this car is for. The car is completely technical, not aesthetic.

      However... there is a caveat.

      Those shortened 911 style rear quarter windows belong on the cayman. I have LONG thought that the Cayman deserved a bit more grace than the up-turned quarter window treatment it has, and some smaller, shorter in height and length versions of 996/997's rear quarter windows would flow the C-pillar area on the Cayman MUCH better than what it has.

      Cayman also needs a Carrera GT/Viper/RX7 or any coach-built-Zagato like double-bubble roof treatment, even just a subtle one.

      9ff is interesting, but I'd like to see some action closer to a level I might someday actually see. A Boxster Spyder, and a corresponding Cayman GT/CS/RS type coupe... sounds good to me.
      • 5 Years Ago
      if the look of the GT9 bother anyone... buy the 9ff TR1000... a normal looking 911 with 1000hp still able to get to 391.7km/h (243mph) with passenger... most likely the TR1000 would have been faster if the straight would have been longer...


      • 5 Years Ago
      drag increases at the square of speed. It takes more and more power to overcome exponentially increasing resistance.

      So yes, it does take a lot more power to add one more mile per hour to 256mph.

      Comparatively it takes barely any power at all to add one mile per hour to 25mph, or 2.5mph.

      At first glance it looks like one of the Scrubbing Bubbles from the commercial.
