Blue Marble Cocktails Radical Cup North America

The Blue Marble Cocktails 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 at iconic circuits across the USA, including current and former Formula 1 and IndyCar venues.

Ample practice, qualifying and three 40-minute races as well as trackside hospitality and social events ensures each three-day Radical Cup event is action packed, both on and off the track. Following last year’s success supporting World Challenge, this year the series is sanctioned by SCCA PRO and will be showcased at a number of high profile events including Blancpain GT World Challenge at VIR, the NTT IndyCar Series at Road America and CREVENTIC's Hankook 24H Series at Circuit of the Americas.

The championship features three classes for the SR8/RXC Spyder, and 1500cc and 1340cc variants of the ever popular SR3.

Series Highlights

  • Drive solo or partner up. A mandatory pitstop in the final race of each weekend allows for a driver change.
  • Supported by all Official Radical Dealers and top independent teams from across North America.
  • Events supported by factory technical personnel.
  • Unique Italian designed Libé trophies.
  • Ethanol free Gulf Racing spec fuel for consistency and fuel cell preservation.
