The Porsche 917/20 takes a special place among the various 917 versions. It remains a unique one-off. Porsche engineers together with the French company SERA undertook the attempt to combine the advantages of the short and long tail 917. Its body was extremely wide and it had extremely rounded wheel cut-outs. Porsche designer Anatole Lapine decided in favour of the pink body colour and labelled each of the body parts according to the butcher-style cuts. Porsche caused a sensation at Le Mans 1971 with the Pink Pig.
