While it might be very good retouching, it is incredibly obvious that it is retouched (CGI, HDR, heavily processed, great finishing, etc. if you prefer).
All you have to do is read the key/shadow lighting on the track relative to the key/shadow lighting on the car and corresponding reflections. The shadows are not natural, they are too light, thus were either fill or somehow touched. They aren't natural fill because the falloff is either not present is some, or it is too prominent in others, and the reflections don't match. The list goes on, but suffice to say these are heavily retouched .. very well, but retouched (nothing wrong with that). No way these are remotely close to sooc with only a light touch of PS.
A comment that there isn't much PS involved ... levels and a mask with brush painting on the mask(s) isn't much involved. However, you can do an enormous amount with it. The definition of not much PS involved is rather nebulous semantics. I think it is fine workmanship indeed, but one should be honest about the fact that great finishing is an integral part of the finished product rather than suggest the finishing wasn't that big of a deal to the end result.
Both capture and finishing are integral components (no foul there) ... so why the need to diminish the role of skillful finishing when it is so obvious? Does that make one more or less of a photographer ... maybe we should ask AA?
