Simple3d - application for rendering 3d objects in real time. Simcar - car simulation with stunts and realistic physics starting with version 5.0.0. No 3d accelerator is required. Car models and some tracks are imported from TORCS and Speed Dreams (Free Art License).
simcar ( version 5.1.0 ) appeared really good to me. Almost as good as Skunks but the compilation is much easier since there is no ODE library to compile and "install".
