In order for the Porsche 917 to be homologated into Group 5, a batch of 25 completed cars were lined up for the FIA to inspect on April 21st 1969. Although (secretly) only a handful were fully functional, homologation was duly approved.

Porsche retained chassis 001 for promotional duty while 002 through 010 were raced during the rest of the season. The remaining 15 were disassembled to be properly rebuilt at a later date.
