Welcome to Prototype Sprint Series Association (PSSA) presented by Hankook!

PSSA is designed to host prototype race cars in a sprint race format at some of the most iconic road courses in America. The series features five on-track sessions split between practice, qualifying and two feature races.

Sanctioned by Parella Motorsports Holdings, entrants in Category I will need a current SVRA super license or equivalent to participate, while those competing in Category II and Category III will require an SVRA Competition License or equivalent.

Nearly 20 chassis are eligible for competition, as PSSA hosts a variety of Radical, Revolution, Ligier, Wolf and Sebeco prototypes, with the mandated use of Hankook racing tires.

Increasing from 8 to 12 events, the 2024 season will mark the debut of the PSSA East and PSSA West championship titles, and will crown a National champion. Each of the PSSA East and PSSA West Champions will be awarded a $10,000 prize and the overall National Champion will be awarded a limited-edition Bell Racing gold helmet. A Constructor’s Championship will also be added in 2024 to recognize the manufacturer that accumulates the most points throughout the season.

Spectators attending PSSA events can expect an affordable event jam-packed with racing action and family fun. Joining a variety of other motorsport series at SpeedTour events, including groups like Trans Am, SVRA, International GT, Formula Regional Americas Championship and Formula 4 United States Championship—there is truly something for everyone. With an “open paddock” policy that allows all ticketholders into the paddock for no additional fee, fans at SpeedTour events are allowed a level of access to both cars and drivers that is not available in most other forms of motorsport.
