A British magazine had access to a prototype of the Porsche 918 Spyder's production version. When the 918 Spyder was first shown to the public, Porsche was considering it just a concept. They had not plans of putting it into production. However, the public's reaction to the Porsche 918 Spyder was so overwhelming, that the German carmaker had to put it into production. Here's a preview of the car Porsche will put on sale hopefully next year.
