The Porsche 908 was a racing car from Porsche, introduced from 1967 in the Porsche 906/Porsche 907/Porsche 910 series of models designed under Ferdinand Piech.
As the FIA had announced in 1967 to change of the rules for the World Championship for Marques by limiting the displacement of prototypes to 3000 cc as in Formula One, the new 908 was the first Porsche sports car that had an engine with the maximum size allowed, as the Porsche 907 only had 2200 cc engines.
The new 3 litre Flat-8 engine produced initially 257 kW (350 hp) at 8400 rpm, as well as some teething problems. Also, being traditionally air-cooled and with only 2 valves per cylinder, it was still down on power compared to more modern F1 designs which delivered over 400 hp (300 kW), but were not suited to last in endurance races.
