Grant Park 165
The Grant Park 165 is a NASCAR Cup Series race held on a street circuit in Chicago, Illinois that began in 2023. This race is the first ever street race contested in the NASCAR Cup Series. The NASCAR Xfinity Series race is also held on the street course on the same weekend the day before the Cup Series race and was also the first street race contested for that series. History

Background
On March 24, 2021, NASCAR announced that an imaginary street course in the Chicago Loop in Downtown Chicago would be the track for the fifth (and what turned out to be the final) race of the 2021 eNASCAR iRacing Pro Invitational Series. The iRacing event was broadcast live on NASCAR on Fox on Wednesday, June 2. Rick Ware Racing Cup Series driver James Davison would win the virtual Chicago street race. Ever since the announcement of the track's virtual creation for this iRacing event, there had been rumors and speculation that NASCAR would like to make this track a reality and have a street race in Chicago on the Cup Series schedule in the future. On July 7, 2022, Jordan Bianchi from The Athletic reported that an official announcement of a Chicago street race being added to the Cup Series schedule would come on July 19. On June 17, Adam Stern from Sports Business Journal suggested that the Chicago Street Course could replace Road America on the 2023 Cup Series schedule as any street course race would likely replace one of the road course races and Road America did not have a contract to have a Cup Series race in 2023. On July 19, the official announcement of the addition of the Chicago street race to the Cup Series schedule took place. After the announcement, NASCAR executive Ben Kennedy confirmed Stern's report of the Chicago street race replacing the race at Road America on the Cup Series schedule in a question and answer session with the media. On March 7, 2023, NASCAR announced that the race would not have a title sponsor and would instead be named after Grant Park, which the street course will pass by. Similarly, the Xfinity Series Chicago street race was named The Loop 121 after the Chicago Loop, the area of the city in which the street course is located. It was also announced on that day that the Cup Series race would be 220 miles and 100 laps in length. NASCAR Hall of Fame member and championship-winning crew chief Ray Evernham stated in an interview on June 25, 2023 that cars should reach between 150 and 160 mph on the fastest part of the  circuit (between ② and ④ on the map). The 2023 running of the event was held in the middle of violent storms lashing Illinois. The start of the race was delayed, and eventually ran for only 78 of the scheduled laps. New Zealand racing driver Shane van Gisbergen and triple Australian Supercars champion won the event. in his first-ever NASCAR race running for Trackhouse Racing's PROJECT91 program after qualifying in third. He also became the first driver to win in his Cup Series debut since Johnny Rutherford in 1963. Following the race win, van Gisbergen left Supercars in 2024 and came to the United States to race full-time in NASCAR. On October 20, 2023, NASCAR announced that the 2024 Cup Series Chicago Street Race would be shortened from 220 miles (354.056 km) and 100 laps to 165 miles (265.542) and 75 laps. This is about the same length of the rain and darkness-shortened 2023 race, which was 171.6 miles and 78 laps long. Past winners

Notes
2023: Race shortened to 75 laps due to darkness following a rain delay, but extended due to NASCAR overtime. References
