Rocket engine. RC candy (sugar and potassium nitrate). Burn a string that holds back a rubber band or spring. "Glucose reaction" pick up the bot and throw it... Small gas motor...

idk about that, but I'll delete my other reply for what it's worth. Personally, I think that's cheating.

Steel plate on the back of the bot. 6 ounces black power on ground behind bot. Drop lit match onto black power. Take cover. NO, wait. Better take cover first and figure out how to light the powder from a save area. Or you could just use a Jetex rocket motor.

Well make a simple mini boiler...fire burning is a chemical reaction. The small fire heats a tiny pot of water and then the steam is put thru a turbine attach to the wheel as it boils it moves the car.
