The 1964 Paris 1000km at Montlhéry, the legendary banked circuit south of Paris, has a special significance in Porsche history.
Late in the season for the international endurance race, a flat-six-powered Porsche lined up on a windy, wet October weekend with Herbert Linge and Gerhard Mitter as co-drivers.
To many, the car was just another 904, but under that distinctive sugar-scoop-style tail was a new Type 901 engine originally planned a year earlier for this sleek, glassfibre sensation.
In typically understated style, the motorsport lineage of six-cylinder Porsches began, a legacy that would stretch on through the 906, 910 and 907, not to mention the famous engine’s mighty dominance powering 911s.
The debut of the first 904/6 was disappointing. Although Linge turned in rapid laps, the car retired early with broken transaxle mountings, a common 904 weakness. That grim season finale is notable for the tragic death of five people, after Peter Lindner’s Jaguar E-type smashed into a stationary Abarth in the unprotected pitlane.
