The Griffins’ car on “Family Guy” is red. It is the family’s familiar red station wagon, most often driven by Peter Griffin around Quahog.
The vehicle resembles a vintage Ford station wagon, with references variously identifying its design as similar to a Ford Country Sedan, Country Squire, or Ford LTD wagon. The series has never established a precise real-world make and model as firmly as its distinctive red color.
The car is part of the show’s visual identity, much like the Griffins’ house at 31 Spooner Street or the Drunken Clam. It is often damaged, crashed, modified, or used in absurd cutaway gags, but it repeatedly returns as the family’s primary vehicle.
A common mix-up is Brian’s car: Brian has been associated with a silver Toyota Prius, but that is separate from the Griffins’ red family wagon. The question refers to the main family car, not every vehicle used by a Griffin.
