The 2025 Radical Cup North America schedule has been released, which features at least two events with the NTT IndyCar Series. The series will again debut at Sebring International Raceway at the start of March, while next year sees Road Atlanta returning to the line-up along with, for the first time, Lime Rock Park.

Radical Cup looks to build upon another year of record grids — which in 2024 averaged over 30 cars per event, including a high of 39 starters in Toronto — and high-level competition in each class from gentleman drivers and veterans along with the next generation looking to make a mark.

The live-streamed series features premium hospitality along with more track time than most, with three 40-minute races along with qualifying and a minimum of 60 minutes practice. Three classes and an additional subclass are aimed at drivers at various stages in their careers.

Pro 1340, with the slightly less-powerful SR3, is proving to be the perfect first step in the series, attracting drivers from country clubs and novice drivers to the series. However, the competition is also strong, as was seen this year with sim-star and newcomer Suellio Almeida beating out former Le Mans starter Chris McMurry.

With downforce levels and lap times akin to USF2000, Pro 1500 is where the stars of tomorrow gravitate, and in which this year part time Indy NXT driver Jordan Missig proved his prowess over Nick d’Orlando and Evan Slater. The class for 1500cc Radical SR3s is also a good fit for older drivers and those over thirty can aim for the Gold 1500 title while attempting to take wins off the young guns, as Jack Yang did at Road America.

Platinum features the 425hp turbocharged SR10, which along with the minimum driver age of thirty attracts the likes of 2002 American Le Mans champion Jon Field along and former SCCA Runoffs P1 champion Chip Romer.

“Radical Cup continues to be an amazing breeding ground for talent young and old — just look at the alumni — but also a place where people come back year after year, so it’s important to offer new challenges,” said Radical Motorsport North American Director Tom Drewer. “This year we’re delighted to be back at Road Atlanta after a few years while debuting the series at iconic Lime Rock Park. Along with the big spectator IndyCar events at Barber and Road America it’s going to be another fantastic season, and we’ve still got one more major event to announce.”
