Hello! I looked at serveral physic's engines (newton, ode, ...) and they all seem to handle also the graphic output. What I am looking for is an engine which can handle car physics and works like this: - Input current position, acceleration, steering, etc. - Output car orientation (e.g. angle around the up-axis) and position. Does such an engine exist (freeware for noncommercial project. Perhaps also with an car physics example.)? Currently I am using code from MarcoMonster's DowntownDriving, but it makes many problems. Thank you,

AFAIK you can use ODE with your own rendering code.
I have never used ODE but I guess after your time step is done
you should call dBodyGetPosition and dBodyGetQuaternion.

Hope this helps.
