Polyphony Digital just released a concept video of the Toyota 86 commercial model (that will be sold in the US under the Scion brand with the FR-S denomination) in Gran Turismo 5.
According to Kazunori Yamauchi, not only the polyphony team created the videos, but they also composed the music track in-house.
You can check out the video past the cut:
