Some of the renders shown have blender 2.68 cycles internal materials and shaders used so these won't be included on other formats but, some textures were used those will be included such as,brake disc holes and tyre treads bump maps are included. These are all packed in model folder together so, no need to download separately as it's not such a big file.
Model is subsurf usable ready,subsurf level 1 sufficient but does not have subsurf turned on by default. Emission objects are included in all formats but only blender will have emissions active as this is also an internal material of blender. Note: unnamed file format is x3d
If you have problems with the non-blender formats then please know that they can be gained through turbosquids free & professional file conversion service.
