an exciting new tradition of GRAVITY RACING has started in the Greater flint area!

The City of Flint’s historical automotive legacy is a tremendous backdrop while racing at Chevy Commons, and the first race served as an exciting celebration for the entire community!

Please see the official program below for a complete recap of the first race. You can also follow along here, here, and here.


Our Race

The Flint Soap Box Derby is more than just a race - it’s a dynamic learning opportunity, an athletic pursuit, and an exciting community event all in one!

Our race provides participating youth the chance to learn by doing, to build enduring friendships, and to cultivate a passion for STEM/STEAM career paths.

Today, the costs to participate in organized competitive events are increasing, and for many, are unaffordable. We believe in the power of community, and recognize the importance of hands-on learning for today’s youth.

Thanks to the generous support of our sponsors, the Flint Soap Box Derby is available for any youth wishing to participate.

After all, its not just racing - it’s GRAVITY RACING!


Our Mission

  • Reintroduce Soap Box Derby racing to the Great Flint Community for hands-on STEM/STEAM education and community partnership.

  • Create a community-wide event for local enjoyment that further generates statewide, regional, and national interest.

  • Partner interested racers with community groups, other community participants, and other local universities, to design, build, and race soap box cars.

  • Implement year-round Soap Box Derby-related educational programs and workshops for team participation.

  • Organize cleanup, restoration, and beautification efforts at Cronin Derby Downs for partnered teams.



Hands-on STEM/STEAM education

Given the relatively short car assembly times and hands-on engagement, this race can serve as a simple platform for development. STEM/STEAM careers are growing in demand, and the Soap Box Derby is one way to introduce technical concepts required in critical fields such as advanced and autonomous technologies.


Have Fun

Cronin Derby Downs

Flint, Michigan put the world on wheels, so it is no surprise that the Soap Box Derby has a cherished legacy in the area. Beginning in 1938, one of the early years of the race, the Soap Box Derby has been a celebrated community event across the City of Flint.

Initially held on Cadillac Street, Mayor Donald R. Cronin oversaw the establishment of a permanent location for local youth to learn about, assemble, and race Soap Box Cars. Cronin Derby Downs opened in 1969, and remains one of the only permanent Soap Box Derby tracks in Michigan.

Over the years, Cronin Derby Downs has played host to many competitive and educational racing pursuits and produced three Soap Box Derby World Champions.

Beginning in June 2019, Cronin Derby Downs will once again host Soap Box racing will be the first race in the Greater Flint area in more than a generation.
