I saw this in the Subaru booth, it’s a ride simulator running Gran Turismo 3. I asked the attendant what was running it and she told me:

It’s powered by three Playstation 2’s and a computer.

It uses three LCD’s for your “windshield” and there is a 42″ plasma to the left of the simulator that shows the current race in replay mode! It also rocks back & forth, front & back a few degrees depending on how you steer.
