Rare Porsche Print (Limited 28/50 Pcs) - Porsche 908 - Pits Le Mans 1968 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 3,000 cc, as in Formula One, Porsche designed the 908 as the first Porsche sports car to have an engine with the maximum size allowed. The previous Porsche 907 only had a 2,200 cc Type 771/1 flat-eight engine developing 270 hp. The new 3-litre Type 908 flat-eight produced 257 kW (350 hp) at 8,400 rpm. Being traditionally air-cooled and with only two valves per cylinder, it still had less power compared to more modern F1 designs which delivered over 400 hp (300 kW), but were not suited to endurance racing.
