I was experimenting with using spherical harmonic lighting to do internal reflections on the track, which was kind of cool, and not an effect I can recall seeing used in a game, however, I can see why now. Although, it did look kind of cool, it just isn't worth it for how how much resources it uses up. I don't think the iPhone will cope.
Where still not sure what new effects will make it into JCS2, but a more realistic shadow is under consideration, but not confirmed yet. One thing that you can definitely expect is a much improved lighting model on the car.
