Solar Car Challenge

The Solar Car Challenge is a year-long engineering program in which high-school teams design, fund, build, document, inspect, and drive roadworthy solar-electric cars. The 2026 Cross-Texas Adventure covered about 650 miles from Fort Worth to Fort Stockton over July 19–23 after three days of scrutineering at Texas Motor Speedway. Teams also submitted a scrapbook, video, and oral presentation. Official 2026 charges were a $2,750 registration fee for up to 15 race participants, a $1,250 racing fee per vehicle, and $200 for each additional credential.
