The model is a mixture of both polygons and subD surfaces.
There are two files to download, both of which are ZIP files containing the source material. Atom 2.zip contains the .mb file (approx. 21mb), whereas images.zip contains all the textures for the model (dashboard, ridges on lights, etc).
Please be aware that the car is NOT rigged, it is NOT designed for destructibility and does NOT have an engine attached. The engine type in these cars is the Honda Civic Type R engine (K20a) if you are looking for accuracy.
Please also take a look at the animation showing the complexity and layers of the model.
