Sanctioned by the United States Auto Club (USAC) in America with title sponsorship from Gordon's Speed Energy brand, the series utilizes identical off-road trucks that originally competed primarily in American football stadiums, but in 2014 began racing mostly on street circuits and road courses, often in conjunction with the IndyCar Series race schedules.
