Just to add a bit that I haven't seen anybody else mention directly: the lighting on the car (whether CG or real) is from the top, left, slightly in front of the car (i.e., closer to us than the car itself).
Note, for example, that the hood of the car shows a highlight on the left side, the front-bumper is highlighted where it's nearly horizontal, and the near fender is brighter where it faces closer to forward (which would be in the darkest shadow if its light was from the sunset behind the car).
I'd agree that it looks like the car is probably computer generated though -- the curves on the top of the hood (for a particularly blatant example) have what looks to me distinctly like Gouraud shading (complete with slight color banding from the looks of things). Making something look like real paint on real metal is fairly difficult. Like lots of computer shading, this looks more like some sort of rubber or plastic. Note, for example, the complete lack of anything resembling a specular highlight anywhere on the car.
