The Pixar theme-park land based on Cars that opened at Disney California Adventure in 2012 is Cars Land.
Cars Land opened on June 15, 2012, as part of a major expansion of Disney California Adventure Park at the Disneyland Resort in Anaheim, California. Its design recreates Radiator Springs, the fictional desert town from the films, with detailed buildings, signs, rock formations, and familiar characters.
The land includes three major attractions: Radiator Springs Racers, Mater's Junkyard Jamboree, and Luigi's Rollickin' Roadsters. It also contains themed restaurants and shops, making the setting a full environment rather than a single ride.
Radiator Springs Racers is one attraction inside Cars Land, not the name of the whole area. Pixar Pier was a later park land with broader Pixar theming, while Route 66 Road Trip is associated with Disneyland Paris rather than the Anaheim land.
