Thanks. I have a bit more modeling to do there. It will have pistons inside to control the shape of the tire. It will be able to squat ther tread when offroading as well as lift the axles with hydrolics for more clearence. It also has a force articulation and angle adjustment. In other words, if it is on an offcamber hill the axles will move into possition to keap the body flat and the axles down hill a little for stability. I will see how much of this I will hit. The engine is an electro air motor. it charges the air and ionizes it then acelerates it through a turbine. It is the air pressure that turns the turbine to move the car. It uses a hydrogen cell for power. I am a dork, I know.
