The Porsche 908 was a racing car from Porsche, introduced in 1968 to continue the Porsche 906/Porsche 910/Porsche 907 series of models designed under Ferdinand Piech. As the FIA had announced rule changes for Group 6 Prototype-Sports Cars limiting engine displacement to 3000 cc, as in Formula One, Porsche designed the 908 as the first Porsche sports car to have an engine with the maximum size allowed.
