Gravity racer

A gravity racer or soapbox is a motorless vehicle which is raced on a downhill road either against the clock or against another competitor. Although most are built for the purpose of recreation, some gravity racing teams take the sport more seriously and compete to win. They are propelled by gravity and can achieve speeds upwards of 112 km/h (70 miles per hour).
