We already told you that 9ff has its sights set on the title of world’s fastest production car, now more details have emerged on how it plans to do that. The 9ff GT9-R will utilize the same 4.0-liter six-cylinder Boxer engine as the GT9 but now making 133 more horsepower for a total of 1,120.  The performance stats are nothing short of amazing with zero-to-62 mph taking 2.9 seconds, 186 mph requiring 15.8 seconds, and a new top speed of 257 mph. The current record, held by the SSC Ultimate Aero TT, is at 256 mph. The GT9-R has two things to worry about:

-         The new-for-2009 SSC Ultimate Aero makes even more power—up from 1,183 to 1,287 hp—and has been aerodynamically enhanced for a higher top speed

-         Don’t rule out the Keatings TKR, which has already produced test runs of 260 mph

9ff plans to build only 20 GT9-R cars. 9ff also guarantees that with the amount of customization available no two cars will be the same. More pictures of the 9ff GT9-R here.

9ff displayed a 900-hp Carrera GT at the Essen Motor Show in Germany over the Thanksgiving weekend. The 9ff GTT900 gains the extra 295 horsepower via a pair of turbochargers that were slapped onto the engine, a revised exhaust, and new camshafts. The show car was painted red with carbon-fiber accents,  had cut-out front wheel wells, and a fixed rear wing.

When 9ff decided to build the world’s fastest car, its crosshairs were on the Bugatti Veyron with its 253-mph top speed. Unfortunately for 9ff, the SSC Ultimate Aero came out of nowhere to take the reins of the title with an average top speed of 255 mph. Not one to just sit in second place, 9ff has decided to tinker with its 254-mph GT9 to hopefully blow the doors off the whole competition. Initial estimates have the 9ff GT9R producing 133 more horsepower and 64 more pounds per foot of torque for a total of  1120 hp and 774 lb-ft. The engine will be the same 4.0-liter twin-turbocharged F-6 engine used in the original car.  

Since only 20 GT9s were ever scheduled for delivery, expect the GT9R to be limited to very few units. Pricing will most likely be above the bargain-priced $785,677 MSRP for the GT9, which pales in comparison to the price paid for a new Veyron.
