gravity racer
Unpowered hill vehicle
A gravity racer is an unpowered vehicle designed to coast downhill, relying solely on gravity and the rider's weight for propulsion.
These range from simple homemade soapbox cars to sophisticated racing machines with aerodynamic bodywork and precision steering.
Gravity racing competitions, from neighborhood soapbox derbies to professional events, challenge builders to optimize speed through weight distribution and reduced drag rather than engine power.
The kids spent weeks building their gravity racer for the annual derby.
