Here is a great video of Porsche Design Manager of Sports Cars, Anthony Hatter in which he details the design process and current status of Porsche’s upcoming hybrid supercar, the 918 Spyder. While the prototype Porsche 918 RSR is a conceptual study, Hatter discloses that many of its exterior design elements were taken from past Porsche race cars, while the new production 918 Spyder will do much of the same.
