Early on Monday, May 15th, Porsche released official photos and “preliminary” specs on the Porsche 918 prototype. While it’s possible this release was planned it may also be a direct response to all the recent spy photos that have started to surface this past week. Regardless, the 918 Prototype shows that Porsche is staying very true to the original 918 Spyder concept unveiled in Geneva more than two years ago. Porsche’s preliminary specs follow below the pictures.
