Historic Technical Passports and FIA Heritage Certificates Questions and Answers

In February 2004, the FIA published on its website a Question and Answer paper dealing with some of the more common enquiries it had received relating to the new system of Historic Technical Passports and FIA Heritage Certificates. The web page was well received and has led to some further queries, which are addressed here.

Have there been any developments since the first Q and A was issued on 18 February? Yes, it has become clear that we need two databases, one for chassis numbers, the other for car specifications.

Why do you need a database of car specifications? We need this in order to make sure that an HTP is only issued to a car which has the specification of the car it purports to be. The HTP is a sporting document. In order to ensure fairness in competitions, it is essential that an HTP is not given to a car which has, for example, a wholly inappropriate braking system or suspension geometry. Either of them might give it a significant and unfair advantage over a car with the correct period specification. This is just as true for an original car as for a replica.

But surely this is what an HC is for? No, the HC deals with the authenticity of the car - it states that in the opinion of the FIA this is the original car. But you could have an original car to which, eg, a modern braking system has been fitted. This would give it an entirely unfair advantage when racing or rallying against cars of the same type (or even the same period) which had not been modified in this way.

So what are the essential differences between an HTP and an HC? The HTP is essentially a sporting document. It is intended to ensure that a car complies with the specification of the car it purports to be. Whether that car is wholly original, partly original, assembled wholly or partly out of period components or a copy or replica built recently does not matter. The essential thing is that it is not, say, a 1968 Formula One car (genuine or replica) fitted with a modern braking system. The HC, on the other hand, is primarily an historical document, concerned solely with the authenticity of the car. It certifies that, in the opinion of the FIA, the car is the real thing, having existed as a complete car with an original chassis/VIN number since it was built in the period to which it belongs. In practice it is unlikely that a car with an HC would have been modified so as to make it ineligible for an HTP, but there will be many cars which are to specification ¡V so eligible to hold an HTP ¡V but not authentic and original and thus entitled to an HC. The HTP allows all these cars to compete, provided the organiser wants them, but ensures they do so on a fair and equitable basis, irrespective of their origins.

Appendix K for pre-1966 GTS cars allows them to be rebodied as replicas of Period cars e.g. low-drag E types.Will these cars whilst original and genuine get HCs? Cars which are genuine and original will be eligible for HCs but there will be a rider on any HC issued identifying the change in bodywork from new .

You have already said that the chassis number database will be confidential. Will this also apply to the specification database? No, it is intended to include this database on the FIA website and allow anyone to look at it. There will be technical details and photographs to assist competitors, ASNs and scrutineers. Further, it is intended that there will be detailed DVDs available of all the popular cars.

How will the specification database be assembled? It will be relatively easy to deal with cars which have been homologated, because we can start with the original homologation papers. Other cars such as racing cars which were never homologated but were simply built to conform to the relevant technical regulations, will be more difficult, particularly those which were already being modified during their original competition period. In these cases we will have to rely on the help of the experts.

Why not just leave all this to scrutineers or organisers as at present? We are trying to set up a system to preserve the heritage of motor sport. At present there are many experts with first-hand knowledge of the 1950s and 1960s, some even of the 1930s. It is essential that we get a proper database set up while these people are still around and before historic motor sport is swamped by the sheer number of historic cars.

How will you settle disputes when experts disagree about the period specification? By looking at all the available evidence. Again, the sooner this is done the better. It will be of great help to ASNs to have a database of specifications on line to back up their expert inspectors. It will also help to eliminate the inevitable differences between the levels of expertise available to our various ASNs.
