What makes a vehicle move?

I'm not sure about other vehicles, but I can tell you how a car moves. In the engine, there are four steps that need to occur. They are intake, compression, combustion, and exhaust. Fuel and air is put into the chamber, the piston compresses the mixture causing it to combust, and then releases it as exhaust. The power from the combustion stage is what causes the engine to move the vehicle. Hope this helps :)
