NASCAR Cup Series season continues with the Grant Park 165 at the Chicago street course on Sunday. See the starting lineup here.

The NASCAR Xfinity Series returns to the Windy City on Saturday for The Loop 110 and the only street race on the season calendar.

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.
