Guido is a small Italian forklift, who works at Luigi's tire shop as his assistant.
Like his boss Luigi, Guido is an avid Ferrari racing fan who dreams of performing a real pit stop on a real race car. To better prepare himself, he practices tire changes at night on wooden practice frames he built in his garage. One of these days, he hopes to set a new world record for the fastest pit stop of all time. But until that happens, he continues his quest to further enlighten himself. Currently, Guido is reading Tire Changes for the Soul, and Four Tires, One Goal.
Guido, the little Italian forklift, is the backbone of Casa Della Tires. He's Luigi's assistant and best friend, and together they are the biggest Ferrari racing fans in Carburetor County. A car of few English words other than "pit stop," Guido is a force to be reckoned with when he's changing tires in the pits during a race. Joining Team Lightning McQueen for the World Grand Prix, Guido will get to show off his turbo-charged, pedal-to-the-metal pit stops on the global stage...and maybe, just maybe, he'll see some Ferraris!
In Cars, Guido ultimately realizes his dream when he works on Lightning McQueen's pit crew under the command of Doc Hudson. Guido deals with the derisive attitude of Chick Hicks' pit crew by single-handedly changing McQueen's tires in record time, something not even four experienced pit crewmen could do.
In Mater and the Ghostlight, Guido is first seen listening to Sheriff's story of the Ghostlight, and later helps the others to prank Mater into thinking that the Ghostlight is after him by placing a lamp on his tow hook.
Cars: Mater-National Championship
In Cars: Mater-National Championship, Luigi and Guido are showing off their new paint jobs when Lightning and Mater drive up, asking them why they are painted like that. They get excited when Giovanni drives up, and challenges them to a race, although Guido does not compete.
He is later seen trying to straighten the tires that keep leaning due to the rumble of Monster McQueen.
In Tokyo Mater, Guido helps modify Mater at the end of the short, shouting "Modify!"
In Cars 2, Guido and Luigi tag along with McQueen as his pit crew. He is seen serving drinks at the beginning of the film. He also watches as Mater talks on the Mel DoradoShow. Later in Tokyo, he doesn't believe that Holley Shiftwell is Mater's girlfriend until the end of the film when she says it herself in a jaw-dropping moment. Uncle Topolino reveals that Guido and Luigi used to always fight, and they are seen fighting over a girl car until another girl car comes, and they are both satisfied. He also helps fight the lemons later in the film. He tries to take off the bomb that was attached to Mater, but his drill won't do it and he gets frustrated and leaves.
Cars 2: The Video Game
In Cars 2: The Video Game, Guido is an unlockable playable character, available the "Frequent Flyer" crest is obtained. Another version of him, titled Team Lightning Guido, can be unlocked by earning the "Bulldozer in a China Shop" crest. Both are light weights, and feature heavy speed and little power.
In Disney Infinity, Guido appears as a cast member in the Cars Play Set. He can be unlocked as a toy box townsperson in the Toy Box when one of the twelve character chests is opened.
In Cars Land, Guido and Luigi have their own ride at Luigi's Casa Della Tires called Luigi's Flying Tires. In the ride, the guests will get into their own fettucini tires. When Guido turns on the air compressor, air will come out of the holes, and the tires will float in the air. There are also some beach balls with the colors of the Italian flag in the ride, and Italian music will play.
In the English version of Cars, Guido speaks Italian. But in the Italian version, he speaks dialect.
Guido is named for the Italian verb “guidare” which means “to drive.”
Pixar supervising technical director Guido Quaroni, who is a native of Monza, Italy, suggested this name to John Lasseter, and was then asked to provide the temporary voice. The director liked his voice so much it made it into the finished film. Guido even got a chance to work on the character he named and voices: in Cars, Guido Quaroni performed shading work on Guido the car!
In the Cars Toons episode Tokyo Mater, Guido says "modify" in English, which is one of the rare times he says an English word, and the only one in a Cars Toons episode.
Guido also says "OK" in Cars. In Cars: The Video Game, Guido says "boss" in English.
He also says "pit stop" in English, but pronounces it as "peet stop".
In the Italian version of the first film, he is voiced by Alex Zanardi.
His paintbrush is seen in WALL•E when WALL•E builds an EVE sculpture, which he used the paintbrush as the left arm.
