Porsches under the Rising Sun – 908/02 K Spyder & Flunder

The 908 marked a defining break with Porsche’s established motorsport engineering philosophy. Until then, only a handful of engines, including the eight-cylinder units derived from the 804 Formula One program, were conceived purely for competition, while most of the company’s racing department had to make do with standard, or, in the best cases, enlarged, derivatives of its street-focused powerplants.

Although admirable in principle and economically sound, Porsche’s road-to-race approach began to show shortfalls by the late 1960s. As rival manufacturers unleashed increasingly sophisticated purpose-built racing machines, it became clear that production-derived engines alone could no longer keep Porsche at the forefront of competition. To challenge the best and pursue outright victory at venues such as Le Mans or Monza, Stuttgart had to rethink its approach.
