Three litres, many forms
The 908 is a prototype family, not one fixed body: short- and long-tail coupés, the open 908/02 and the 545-kilogram 908/03 all carry the number. Collectors buy a specific chassis, race record and reconstruction history.

Estimate band for good road cars. 2 documented sales since 2019 plotted below.
Band and axis shown in USD. Sale positions use indicative fixed-rate conversion to USD; sale readouts retain recorded currencies. Indicative only. A works result, original frame continuity, installed period engine and an accepted expert report can each move a chassis outside the range.
Instrument calibration for this file is in progress — the terminal above reads the documented record directly.
The sole ledger amount is the auction house's published USD result. No-sale estimates are not entered as sales.
Overview
Porsche designed the 908 for the three-litre prototype formula introduced for 1968. Early flat-eight engines suffered severe vibration; revised firing order and crankshaft work made the package durable enough for endurance racing.
Open 908/02s helped Porsche secure the 1969 World Sportscar manufacturers' championship. For 1970, Weissach shortened and lightened the concept again into the 908/03 for the Targa Florio and Nürburgring while the 917 covered the fast tracks.
Works priorities moved on, but private teams continued developing and racing 908 chassis into the early 1980s. Period repairs and later reconstructions are therefore normal parts of the provenance file, not footnotes.
