2013 Nissan GT-R Nismo GT3 racecar prototype undergoing testing

Nissan introduced its privateer Nissan GT-R Nismo GT3 racecar last year. Unlike GT-Rs competing in other series like GT1 and Japan's Super GT, the GT3 version utilizes the same 3.8-liter twin turbo V6 from the street car, the engine retuned to produce 523 horsepower. Nissan and Nismo engineers are already hard at work on next year's entrant, throwing the development car over the curbs at what looks like Fuji Speedway.

If you want to buy one, it'll cost you just about 300,000 euros ($380K US). If you just want to watch and hear one, you can watch the video below for free.
