The Superspeedway configuration at Auto Club Speedway in Fontana, California represents the facility's 2-mile D-shaped oval designed for high-speed stock car racing, distinguished by progressive banking ranging from 3 degrees in turns to 14 degrees creating multi-groove racing opportunities. The Superspeedway serves as Auto Club's primary configuration hosting NASCAR Cup Series and other major oval racing events. This layout emphasizes sustained high-speed running where cars exceed 200 mph through banked turns.

What distinguishes Auto Club's Superspeedway from typical intermediate ovals is the progressive banking that creates multiple racing grooves allowing drivers to run various lines through turns. Southern California's climate creates year-round racing potential though desert heat pushes track temperatures above 60C during summer. The Superspeedway configuration established Auto Club as Southern California's premier oval racing venue, serving NASCAR's West Coast presence with championship-level infrastructure near Los Angeles metropolitan area.
