CHARLOTTE (July 2, 2026) – Exactly 10 years ago today, Formula 4 United States Championship (F4 U.S.) made its debut in North America. Contesting a triple-header weekend at the 2.258-mile Mid-Ohio Sports Car Course, the series kicked off a successful championship, which has since crowned 10 champions and celebrated 54 different race winners on the podium.
The 30-minute race on July 2, 2016 saw Konrad Czaczyk beat now-INDYCAR driver Kyle Kirkwood. Cameron Das went on to win the championship that season before climbing the FIA ladder up to FIA F3 in Europe. In fact, the drivers who competed that afternoon at Mid-Ohio have gone on to race in INDYCAR, FIA F3, the NASCAR O’Reilly Auto Parts Series and IMSA Endurance.
In the championship’s 10-year history, Kyle Kirkwood has proven to be the winningest F4 U.S. driver with 10 victories recorded over his two seasons in the series. Meanwhile, Cooper Shipman holds to the record for the most consecutive F4 U.S. victories after tallying nine in a row on the way to his 2025 title.
Champions of the series include not only six-time INDYCAR winner Kyle Kirkwood (2017), current FIA FORMULA 2 driver Noel León (2021), and INDY NXT racer Lochie Hughes (2022), but also former FIA F3 drivers Cameron Das (2016) and Hunter Yeany (2020).
A proven training ground for drivers starting their professional racing career, INDYCAR winner Christian Rasmussen started in the F4 U.S., as did current INDYCAR racer Nolan Siegel. Before becoming the FIA F2 reserve driver for Van Amersfoort Racing, Ricco Shlaimoun also began his open-wheel career in F4 U.S., as did F1 ACADEMY drivers Chloe Chambers and Ava Dobson. Proving that the skills learned in the championship can translate to any type of racing, both Baltazar Leguizamon and Andrew Castro used the race craft they learned in F4 U.S. to reach the NASCAR O’Reilly Auto Parts Series.
Hundreds of drivers have traveled from around the globe to compete in F4 U.S. over the last decade, making it one of the most sought-out junior open-wheel categories in the world. Prospective drivers looking to learn more about F4 U.S. should visit the championship’s website, F4USChampionship.com.
