ODE v0.035 has what they call a Universal Joint. It looks exactly like what you see in real-world driveshafts. I think you will need that baby :)

Applying torque to the driveshaft can of course be done by setting the torque manually, or by using a hinge or angular motor joint and setting that to apply the torque you need. I think using joints is prefered to setting torque manually.

I don't know how to transfer that torque to the wheels, except by simulating some sort of differential. See next question.

This might be an interestsing new joint design for ODE. But to be honest, I wouldn't know how to do it.

Addicted as well, eh? :D
