Prior to 2005, the race was held in late April or early May, and until 2010, the race was run at a length of 500 miles. When the NASCAR Realignment of 2005 was made, the race was moved to February and the week following the Daytona 500.[1] The race was moved from February to March in 2011. After being pleased with the results of the shortening of the track's former fall race date, the Pepsi Max 400, from 500 to 400 miles, this race was also shortened to 400 miles in 2011.[2]
The Automobile Club of Southern California, the title sponsor of the track, was the title sponsor of the race from 2003 to 2020. WillCo Intelligent Stored Energy (WISE) Power became the title sponsor of the race in 2022.[3] The Pala Casino Resort and Spa became the title sponsor of the race in 2023.[4]
