In Pixar's Cars, Porsche made the model used for Sally Carrera.
Sally is specifically designed as a 2002 Porsche 911 Carrera. The sports car's rounded body, rear-engine layout, and characteristic silhouette distinguish her from the American stock cars and trucks that dominate Radiator Springs.
The character's full name combines the Porsche model line with a personal name. She is not merely described as a generic Porsche: her model is a 911 Carrera, a version of Porsche's long-running 911 sports-car family.
Sally's identity can be confused with other Cars characters based on real manufacturers. Luigi is a Fiat 500, Guido is a forklift, and Lightning McQueen is a fictional stock car rather than a production model from one manufacturer.
