Volgens het Engelse Autocar heeft Porsche de intentie om de straatlegale versie van de 918 alleen als Spyder te produceren. De baas van ontwikkeling bij Porsche zei dat de 918 RSR verder ontwikkeld zal worden naast de 918 Spyder. Wolfgang Dürheimer vertelde dat de hard-top versie van de 918 alleen gericht gaat worden op de autosport.

“The road application of this car is the 918 Spyder. There is no decision taken that the coupé type will be available on the Spyder. We learned from the Carrera GT that the driving pleasure of the car is enhanced when you have the possibility to drive open or closed. We have always told people interested in the 918 Spyder that it will have a roof concept similar to the Carrera GT’s, with a lightweight carbonfibre panel. A closed car is better for motorsport, though.” Aldus Wolfgang Dürheimer.
