History
On October 1, 2013, after a feasibility test in September, it was announced that an IndyCar race for 2014 would be held on the GP Circuit, either as a "doubleheader" event in May prior to the Indy 500, or as a stand-alone race in the fall. Up until the announcement IndyCar hadn't raced on the F1 GP Circuit, though Indy Lights had four times.
