The third and final race weekend of NASCAR’s three-year deal with the city brought fans from throughout the country, with first-time race attendees and seasoned fans flooding through the gates.

This year, the increasing intensity of the battle for the NASCAR playoffs takes center stage in Second City, as only four open spots for non-winners now remain on the playoff grid. One such spot was filled last week, when local hero Chase Elliott won in Atlanta to stamp his place in the playoffs and clear the way for his run at a second Cup title.

Van Gisbergen has won the pole for Sunday's Grant Park 165. The 36-year-old New Zealander turned a lap at 88.338 mph on a tricky 2.2-mile course that was made more treacherous by temperatures in the 90s Fahrenheit on Saturday.
