These miniature racing vehicles, originally crafted from wooden soapboxes or apple crates, have evolved into more advanced versions made from materials like aluminum, fiberglass, and even carbon fiber.

The roots of soapbox racing trace back to Frankfurt, Germany, in the early 1900s, where gravity-powered races with these cars first took place. As time passed, their popularity surged, with over 50 U.S. cities participating in these competitions by the 1930s. The pinnacle of these races was the championships held in Akron, Ohio.

Soapbox derby race rules vary regionally but typically include the following conditions:

1. The vehicle must be non-motorized.

2. Four wheels are mandatory.

3. A braking mechanism is required.

4. An initial push at the race's outset is allowed.

5. All drivers must wear helmets.

The soapbox derby races in the United States have witnessed their share of controversies. One competitor incorporated electromagnets into their car's nose, secretly activated at the starting line to gain an initial speed advantage—this trick was exposed through an x-ray examination of the vehicle.

 Another racer faced disqualification for applying chemicals to the rubber wheels, reducing resistance during the downhill run.
