=== Expansion and additions ===
With early success following the opening of the track, the speedway began to expand reserved grandstand seating along the front stretch with an additional 15,777 seats. In May 1999, an additional 28 skyboxes were added to the top of the main grandstand. In 2001 the Auto Club Dragway, a {{cvt|0.250|mi|km|abbr=on}} dragstrip, was built outside of the backstretch of the main speedway. That same year, the infield of the speedway was reconfigured to hold a multipurpose road course. On April 24, 2003, The San Bernardino County Planning Commission approved the changing of the speedway's conditional use permit to allow the installation of lights around the track. Later that year NASCAR announced a second annual NASCAR Cup Series race at the track for the 2004 season, with the second race being run "under the lights".<ref>{{cite web|author=Jensen, Tom |date=August 7, 2010 |url=http://www.racingconnection.com/NascarEventPackages/california_speedwayseating.htm |title=California Speedway |publisher=Racingconnection.com |access-date=September 14, 2010}}</ref> NASCAR ran two weekends of racing annually until the [[2011 in NASCAR|2011 season]], when the track returned to a single annual race weekend.<ref>{{cite web |url=http://nascar.speedtv.com/article/cup-auto-club-loses-chase-date/ |title=NASCAR&nbsp;— CUP: Auto Club Loses Chase Date&nbsp;— SPEED.com |publisher=Nascar.speedtv.com |date=August 7, 2010 |access-date=September 14, 2010 |archive-url=https://web.archive.org/web/20100818074629/http://nascar.speedtv.com/article/cup-auto-club-loses-chase-date/ |archive-date=August 18, 2010 |url-status=dead |df=mdy-all }}</ref>

In 2006, the speedway's midway, located behind the main grandstand, was overhauled. The new midway, called the "Discover IE FanZone", included the addition of Apex (a [[Wolfgang Puck]] restaurant), additional shade and lounge areas, a retail store and an entertainment stage.<ref>{{cite web|title=2006 Racing Season Concludes, 2007 Just Around the Corner |url=http://www.autoclubspeedway.com/Articles/2006/10/2006-Racing-Season-Concludes-2007-Just-Around-The-Corner.aspx|publisher=Autoclubspeedway.com|date=October 5, 2006|access-date=September 13, 2010}}</ref>

In March 2014, the Las Vegas-based company Exotics Racing expanded to California by opening a new 1.2 mile road course at the Auto Club Speedway.
