DETROIT — On Friday, June 2, Comerica Bank will once again support a tradition that began with the very first Detroit Grand Prix in 1982. Paddock access is not included with Free Prix Day seating and no tickets will be required to sit in either grandstand on Free Prix Day, courtesy of Comerica Bank. The return of Comerica Bank Free Prix Day extends the tradition that began with the very first Grand Prix event held on the Streets of Downtown Detroit. The on-track action on Comerica Bank Free Prix Day will feature all four series competing at the Grand Prix.
