In Pixar's Cars, the Porsche 911 who becomes Lightning McQueen's friend is Sally Carrera.
Sally is a 2002 Porsche 911 Carrera, specifically from the 996 generation. She works as the town attorney in Radiator Springs and owns the Cozy Cone Motel. Her character helps McQueen understand that Radiator Springs is more than an inconvenient stop on his way to the Piston Cup race.
Sally is voiced by Bonnie Hunt in Cars. She is also one of the film's main emotional links to the town's history: she chose to leave a busy city life and settle in Radiator Springs after discovering the charm of the old Route 66 community.
A common mix-up is confusing Sally with Flo, the owner of Flo's V8 Café, or with Holley Shiftwell, the spy character introduced in Cars 2. Sally is the blue Porsche and McQueen's principal romantic interest in the first film.
