The Toyota All-Star Showdown was a nonpoints, all-star race that brought together the top drivers in NASCAR's lower-level series.
It was inaugurated in 2003, and all six events so far have been held at Toyota Speedway at Irwindale in suburban Los Angeles. Historically held in October or November, NASCAR moved the 2008 season event to January 23–24, 2009, after all of NASCAR's regional series had finished their 2008 seasons. The Showdown was cancelled in 2011. It was replaced starting in 2013 by the UNOH Battle At The Beach.
In 2006, the Showdown was a two-race card, as it had been throughout its brief history. One was for drivers in the AutoZone Elite Division, comprising the Northwest, Southeast, Southwest, and Midwest divisions. The other was for drivers in the Grand National Division, which was made up of the Busch East and AutoZone West Divisions.
The top 15 drivers in points in each of the two Grand National series comprised the field for that division's race for a total of 30, while the top 10 drivers in points in each of the four Elite series set the field for that division's race, or 40 in total.
On Friday night, the fields were split in half and the drivers competed in qualifying races (akin to the Gatorade Duel) to determine the starting lineup for the following night's main event. The drivers with the worst position in their respective division's standings started at the front of the field, and the lineups were filled by alternating the series. (For example, a Northwest driver followed by a Southeast driver followed by a Southwest driver followed by a Midwest driver.)
