At this stage in the project I thought it would be worthwhile exploring whether or not there is even a remote possibility a XJ13 copy could qualify for FIA HTP papers - the possibility of continuing on where Jaguar left off and competing against the GT40s in events such as The Le Mans Classic is very appealing!
For those who may not be familiar with HTP registration, there are two kinds of FIA registration - HC (Heritage Certificate) and HTP (Historic Technical Passport). In simple terms, a HC is concerned with the authenticity of the car - it states that in the opinion of the FIA this is the original car. However, a 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.
So ...... pen in hand, I made tentative enquiries to the individuals responsible for allocating HTPs. My thought was that, at this stage, it would be possible to build a XJ13 copy with HTP in mind. However, if I have some inkling at this stage that a HTP is completely out of the question, I can be much more flexible with the specification of the finished car. I assumed that the biggest hurdle I would have to overcome would be the fact that it would be entirely impracticable for me to replicate the quad-cam of the original and I would have to use a later SOHC V12.
After some very friendly and helpful comments from the FIA officials, I learnt the following ...
- "FIA Appendix K rules insist any car copy has to be a completely correct technically‘, so effectively you would be looking at a ‘toolroom’ copy. It has been done, but it is not easy, more than a few have not been accepted. Therefore, I have to advise you that as the FIA rules require that any ‘copy’ car is a true copy, a substitute V12 of different configuration would not be acceptable for this process."
- "There would also be another hurdle to overcome, in that the XJ13 never participated in a race meeting, and thus a true copy or even the original car would not automatically qualify for an HTP anyway!"
