Gravity racer

A gravity racer or soapbox car is a motorless vehicle which is raced on a downhill road either against the clock or against another competitor. The vehicles are powered entirely by gravity; therefore, they are constructed to be as aerodynamic as possible in order to reduce air drag and optimize mass and weight distribution for maximum speed.
