In 2015, Porsche's executive board ordered Weissach engineers to design and build the lightest sports car possible based on the 981. It was to be more minimalistic than the 981 Spyder. Some of the inspiration came from the 1968 Porsche 909 Bergspyder. This is one sexy one-seater and roofless extreme machine. It received the 3.8-liter Cayman GT4 engine, which was tuned to produce 387hp (up 7hp). Expected Nürburgring time of around 7:30 minutes.
