What is the name of the demolition derby event shown in Pixar’s Cars 3?

The demolition derby event shown in Pixar’s Cars 3 is the Thunder Hollow Crazy Eight.

Lightning McQueen enters the event while trying to regain confidence after struggling against the younger, technologically advanced racer Jackson Storm. The race takes place at Thunder Hollow, a rough dirt track, and uses a figure-eight course where collisions and vehicle damage are part of the spectacle.

The event is a major comic sequence because Lightning is accustomed to professional stock-car racing, while the Crazy Eight demands survival in an uncontrolled demolition-derby environment. Cruz Ramirez also becomes involved, and the chaotic race contributes to their changing partnership.

The name is easy to confuse with the Piston Cup, which is the professional racing championship central to the trilogy. Thunder Hollow Crazy Eight is a specific local event, not the championship Lightning has traditionally pursued. Cars 3 uses it to move the characters away from standard oval-track competition and into a different racing culture.
