The LEGO Duplo Cars theme is a branch of the LEGO Duplo line that focuses on characters and scenes from the Disney-Pixar "Cars" movies. These sets feature larger, easy-to-handle pieces tailored for younger children, and they depict recognizable characters like Lightning McQueen, Mater, and others, as well as related settings and scenes from the films. The theme provides young builders a way to interact with the "Cars" universe in a tactile manner, encouraging imaginative play through recognizable story elements.
The LEGO DUPLO theme is designed for children ages 1 to 5. It features DUPLO figures which are much larger than minifigures and DUPLO blocks which are about twice the length, width, and height of a standard System brick.
