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, but were not suited to endurance racing.

The 908 originally was a closed coupe to provide low drag at fast tracks, but from 1969 on was mainly raced as the 908/2, a lighter open spyder. A more compact 908/3 was introduced in 1970 to complement the heavy Porsche 917

The Porsche 908 LH Long Tails were the fastest in qualifying and the early stages of the race, but it showed that Porsche had not taken advantage of the additional time to improve the 908. Troubles with the alternator caused delays and even disqualifications as the new Porsche team leaders had misinterpreted the repair rules. Once again, a V8-powered Ford won, and a 907 Long Tail came in second in front of the sole surviving standard 908. In addition, Ford won the 1968 International Championship for Makes.

1969

For 1969, the Group 6 prototype rules were changed, and Porsche lowered the weight of the Porsche 908/02 Spyder by 100 kg (220.5 lb), removing the roof and the long tails. Aluminium tube frames were used, with air pressure gauges to check them.
