Justin Haley, who started last in the series’ inaugural street race last July, moved into the lead with 30 laps remaining and with the race length cut short due to impending darkness, he was good on fuel to the finish.
As it turned out, van Gisbergen, the three-time Supercars champion making his first Cup start, passed Haley for the lead on a late-race restart and held him off again in overtime to claim the win on the 2.2-mile, 12-turn course through the Grant Park area of downtown Chicago.
