Rally legend Walter Rohrl presents the Porsche 918 Spyder on the most demanding race track in the world - the Nurburgring Nordschleife. Herr Rohrl says about the Porsche 918 Spyder that it's much easier to exploit at the limit, in comparison the Carrera GT, which was a benchmark in its time. In case you're not familiar with the 918 Spyder, we'll have to tell you it's a 700+ hp supercar that offers 94 mpg.
