While Gran Turismo 5 was in development, Polyphony Digital CEO Kazunori Yamauchi approached Red Bull Racing's chief technical officer Adrian Newey to design a new car for the game. To make it interesting, this new car wouldn't be constrained by the regulations and other limitations that typically govern race cars. The result was the X2010, a vehicle that could hypothetically go from 0 to 193 KPH (about 120 MPH) in 2.8 seconds. As Newey points out, to actually build the vehicle would cost millions of dollars, so we'll have to settle for the shell pictured above and the in-game car.

If you're curious about how Red Bull approached the project, check out the video below. In addition to details straight from Newey, there's also plenty of footage of the shell being constructed, for all you CNC fabrication enthusiasts out there.
