A weekend of racing in the streets of Chicago roars into Sunday for the running of the NASCAR Cup Series Grant Park 165.

Through nearly 75 years of its history, NASCAR had raced all across the United States on all types of racetracks, from the smallest of dirt ovals to the biggest and fastest of superspeedways. But never before had NASCAR's top level raced on the streets of a major city -- until the city of Chicago changed all that.

The NASCAR Cup Series continues tonight, as racers compete in the Quaker State 400 this evening. Fans can watch this NASCAR race for free online.
