Porsche has collaborated with Pixar Animation Studios to develop a one-off Porsche 911 inspired by the Sally Carrera character from the animated flick Cars.

The 911 Sally Special is based on the 473-hp 911 Carrera GTS. The manual-drive car features a custom Sally Blue Metallic color.

The Turbo-inspired wheels are redesigned by Style Porsche designers, with their five-spoke design receiving a subtle modification to match the 20/21-inch diameter of current-generation wheels on the 911.

The vehicle will be auctioned by RM Sotheby’s on Aug. 20 during Monterey Car Week. Proceeds will support young girls through Girls Inc. and USA for UNHCR, the UN Refugee Agency.
