Jean-Karl Vernay had a chance to wrap up the title with a round to spare, but with James Hinchcliffe finishing ahead of him, his 48-point championship lead meant that Vernay will only need to start the final race on October 2 to become champion. Adrián Campos Jr. equalled his best finish to place fourth, a car length behind Vernay while Gustavo Yacamán finished fifth after starting on the back row. Daniel Herrington returned to the series as a raceday replacement at Bryan Herta Autosport for Sebastián Saavedra who parted company with the team but only made it as far as lap two, when he was involved in a three-car crash with team-mate Stefan Wilson and Philip Major, which brought out the only caution of the race, before the race was halted for 15 minutes to sweep the circuit of debris. All three drivers were unhurt in the incident.
