Porsche Boxster Bergspyder

In 2015, Porsche built a light and reduced sports car based on the generation 981 Boxster. It was to have an especially radical and uncompromising design in order to achieve an exceptional power-to-weight ratio and superior driving dynamics. Name and colour refer to the lightest racing car ever used by Porsche, weighing in at 384 kilogrammes: the 909 Bergspyder from 1968. The engineers built the Boxster as a single-seater sports car without a top, door handles or windscreen. Both rear and front lids were made of carbon fibre. A flat, transparent wind deflector extended around the driver and ended at the doors. The dashboard was fitted with elements from the Porsche 918 Spyder and the seat also came from the technology show car. A storage room behind the passenger door offered space for a helmet, the removable cover made of leatherette and more luggage. After this lightweight design treatment including weight-optimised components, the ready-to-drive Boxster Bergspyder weighed 1,130 kilogrammes – 185 kilogrammes less than the spartan Boxster Spyder from series production. Powered by the 289 kW (393 PS) boxer engine from the Cayman GT4, the Boxster Bergspyder had a power-to-weight ratio of almost 2.8 kilogrammes per hp. It sprinted from zero to 100 km/h in just over four seconds. Due to admission restrictions in potential markets the prototype remained a one-off.
