Red
Red is a shy and timid fire truck and a supporting character in the Cars franchise. He was voiced by the late Pixar story artist Joe Ranft (who died in a wreck before the film's release) and currently Joe's brother Jerome in most other appearances. He is a supporting character in Cars and Cars 3, and a minor character in Cars 2.
Red gets upset easily and he's been known to retreat to his fire station when things get on top of him, which seems to be most of the time. Red might be shy, but he also has a lot of friends around town who feel very protective toward him.
Red's hose is always very useful. Not only does he water all the town's flowers but he has also given Lightning McQueen a good soak from time to time.
Red doesn't speak much (aside from sobbing, gasping, crying and grunting).
