The car was edited with Rhino 5, and rendered with Ocean. No post-processing was done on the images except a slight sharpening. No 2D compositing was done, all the ground shadowing is based on physical environment models with envmap based ground albedo.
The model is an Audi R8 model in IGES format, freely available on GrabCAD. It was triangulated with Rhino 5, the resulting triangle count being approximately 8.6 million.
