Radical Cup North America

Radical Cup North America is the continent’s premier Radical championship, and offers multi-class Le Mans style racing for a fraction of the price.

The 2018 season will take pace during some of North America’s largest spectator sportscar events at iconic circuits across the USA and Canada, including current and former Formula 1™ venues.

Ample practice, qualifying and three 40 minute races as well as trackside hospitality and social events ensures each three day Radical Cup event will be action packed, both on and off the track.

Following last year’s success, the series has been elevated to an official support series of Pirelli World Challenge in 2018 and is now sanctioned by ACCUS/FIA affiliated United States Auto Club (USAC).

Whether you’re a karter looking to make an impact infront of professional teams, or a gentleman driver looking to take their club racing to the next level, the Radical Cup North America is for you.
