Radical Cup North America closed out its 2026 season this weekend at the Circuit of the Americas (COTA), where a 33-car, four-class field shared the stage with the FIA World Endurance Championship for a fitting final act to the year. Over three days of competition on the 3.426-mile Austin, Texas circuit, drivers turned in a full slate of qualifying and three 40-minute feature races, and by the time the checkered flags fell on Sunday, three of the series' four class championships had been decided – with one delivering the biggest twist of the season.
After five rounds and a summer's worth of racing from Sebring to Sonoma, Road America to Road Atlanta and Lime Rock Park, the 2026 Radical Cup North America season comes down to one final weekend.
Broadcast coverage of Radical Cup North America has been enhanced this season thanks to GPX Stream's plug-and-play onboard streaming system.
