In Pixar's Cars, which animation studio co-produced the film with Pixar?

In Pixar's Cars, Walt Disney Pictures co-produced and distributed the film with Pixar.

Cars was made by Pixar Animation Studios and released through Walt Disney Pictures in 2006. At that time, Pixar and Disney had a long-standing feature-film partnership, with Disney handling distribution and associated studio functions while Pixar created the computer animation and production.

The film was the seventh feature-length production from Pixar. It followed The Incredibles and preceded Ratatouille in the studio's release history. Cars became a major franchise through sequels, short films, merchandise, and theme-park attractions.

Walt Disney Pictures is the relevant studio label for the film's original release, not a separate animation company that created the movie. Pixar became a wholly owned Disney subsidiary in 2006, the same year Cars reached theaters. That corporate timing can lead to confusion when people describe Cars as either a Pixar film or a Disney film; both descriptions identify different parts of its production and release history.
