I modelled and rendered the Formula BMW with Softimage XSI as a work for a friend. The car was supposed to have custom made liveries, so this one was just the basic one. Also the cockpit was highly detailed. It was supposed to be added in a new release of NetKar Pro, but unfortunately this mod never saw the light. I still have the specifications for the mod:

7000 triangles (wheels excluded)
1 x 1024 texture for the chassis
1 x 512 texture for the engine
1 x 512 texture for the cockpit
1 x 256 texture for the steering wheel
