The FIA Historic Motor Sport Department has been working on this for a couple of years now and it is available to the public for consultation.
First version as presented online is the first development with the main focus being on Homologation Forms and with 3255 of them having been published with more than half being of new quality (modern digitalized documents).
Second part is dedicated to regulations with 43 period FIA Technical Regulations available with a selection of 30 other period regulations (ex: 1930 European Hill Climb, 1975 Trophée de l’Avenir and 1988 IMSA Code to name a few) as well as the actual FIA Appendix K for Historic Motor Sport.
All these documents are available for consultation and at disposal of competitors as well as organisers and officials and people who are looking for period information. A tool that will certainly grow in the future, contributions being invited and which we hope will make the sport understood but above all, which will enable us to continue what historic motor sport was first meant to be, an active celebration of the history.
