35 Years

PRISUM Solar Car Club has been a student organization at Iowa State University since 1989. Founded as a Tau Beta Pi project, PRISUM Solar Car is one of the longest running solar car teams in North America. We have been competing in the American Solar Challenge (formally Sunrayce) since 1990. Our determination to innovation and participation in the sport is unique to only one team in the world, and that is PRISUM.


The American Solar Challenge is a competition to design, build, and drive solar-powered cars in a cross-country time/distance rally event. Teams compete over a 1,500-2,000 mile course between multiple cities across the country. The event has had over two decades of organized events in North America.

The Formula Sun Grand Prix is a track event that is held on grand prix or road style closed courses. This unique style of competition truly test the limits of solar cars in handling curves, braking, and acceleration. Strategy applied during these three day events is different than what is applied on the cross-country event.
