High Quality Content by WIKIPEDIA articles! Sir Tow Mater or better known as Mater is the deuteragonist in the 2006 animated Pixar film Cars and the main protagonist in its sequel. He is voiced by Larry the Cable Guy, and was inspired by a 1951 International Harvester tow truck but bears more of a resemblance to a 1955–57 Chevrolet or GMC; the actual inspiration may be the 1955–56 version since the hood which Mater recovers at the end of the film after a twenty-year absence lacks the "gunsights" of the 1957 model. Originally portrayed as a sidekick and friend to the film`s main protagonist, Lightning McQueen, the popularity of the character eventually made him the central character in Cars spin-off media like the Cars Toons series, the Mater and the Ghostlight short and the Cars Mater-National video game, and one of the two central characters in the film Cars 2. He also appears as the main deuteragonist in other media related to Cars. His name comes from "tomater", a slang term for Tomato.
