Introducing Toni Breidinger, SI Swimsuit’s Newest Athlete

Toni Breidinger trades her signature black-and-white sporty racing suit for stunning swimwear at The Boca Raton, as she poses for photographer Ben Horton as the 2025 Sports Illustrated Swimsuit issue’s newest athlete.

If you’re unfamiliar with the award-winning race car driver and model, you’re in for a treat. Breidinger has quickly risen to become one of NASCAR’s most prominent figures as a history-making competitor, a trailblazer for women in the male-dominated sport that is pro racing, and a burgeoning influence in the fashion and modeling industries.

“We are thrilled to launch our shoot season for the 2025 issue with an extraordinary lineup of powerful female athletes,” MJ Day, SI Swimsuit editor in chief, shared. “This remarkable group, featuring Olympic medalists, world champions, and record holders, embodies the next generation of all-stars poised to transform the world of sports. They defy stereotypes and champion equality, inspiring young girls to envision themselves as both athletes and leaders. At SI Swimsuit, we’ve always celebrated the future of women, and there’s no better way to honor these remarkable achievements than by featuring them on the pages of our issue.”

Breidinger’s athletic achievements

The 25-year-old first fell in love with the sport at the age of nine, racing at the Sonoma Raceway in her hometown in California. After six years of go-kart racing, she switched to open-wheel racing at 15, where her skills shone in the U.S. Auto Club Series. With 19 victories, she caught the attention of the racing community and switched to stock car racing at 19. Since her NASCAR debut in 2021, Breidinger has made history as the first Arab-American woman to compete in the sport and has become the female driver with the most Top 10 finishes, with 23 under her belt.

Racing for Toyota Racing Development, she has continued to build an impressive record, amassing one podium finish at the ARCA Menards Series in 2023, five top-5 finishes, and 27 top-10 finishes. Her most recent accomplishments include a historic 2023 showing as the first female driver to compete in two NASCAR races in a single day, and a stellar fourth place in the 2024 ARCA Series championship. With an eye on moving up through the ranks of NASCAR, Breidinger shows no signs of slowing down.
