Look , first the demo you have shown me is extremely optimized.The model of the car has probably very few polygons(how many your car has?) Also the scene is empty from any geometry except of the ground plain. Start adding more geometry and more simulations and you will see your FPS start lagging .I recall a few month ago one guy posted here his car racer demo which used his own physic.It looked awesome and the app was very lightweight,Of course it demands from you learning some (not so complex) physics to set such a thing up .
Regards PS: do you use Away or AwayLite? The second could make your life easier ...
