Established in 2009 by Napleton Porsche of Westmont, Illinois, the Cayman Interseries is North America’s only auto racing championship featuring the exclusive use of the 320-horsepower Porsche Cayman S. Sanctioned by Historic Sportscar Racing (HSR), the Cayman Interseries is conducting its first official season in 2010 and will crown a pair of champion drivers in both the sprint and endurance racing formats. Races will be run on legendary circuits such as Daytona, Sebring, Road America, Watkins Glen, Road Atlanta and other premier venues. Every competing Porsche Cayman S is exclusively supplied and prepared by Napleton Porsche and each car competes with an assigned and specific heritage livery themed after a famous Porsche race car from the past.
