Algodoo

It would be cool, if you could make a faster and mayebe crushable version of this

yes i v2.0 version is making and will by 8 cylinders) it will be fast)

Cool, but I'd put the spring in the cylinder, and make the accelerometer dependent of the engine. And you can use a stretched hinge for the connection between the engine and the rear wheel. (Use only one wheel, a 4wd car goes slower).
In the spring, use legacyMode 0 or 3. If you're using legacyMode 3, put constant 150 or more, and dampening -1.
And in the piston, put inertiaMultiplier 5 or 10, to avoid turning it. Move the rod closer to the center, not much, and if you can, make the spring turn like toni's engines. (That will need two springs turning opposite on Algodoo. See my Mercedes C250 CDI's engine.)

Oh, and never use polygons on the block or the piston! The polygons have worse collision than a box or a circle. Use boxes.

Anyways, I'm waiting for the v8 .
