There was a mid-engined V12 Le Mans racer developed by Jaguar in the 1960's -- the Jaguar XJ13. However, XJ13 used construction techniques similar to the Jaguar D-Type before it: a bonded and riveted aluminium monocoque rather than a tubular spaceframe chassis.

At a guess I would suggest that the chassis you have was constructed by a car enthusiast rather than being anything produced by Jaguar themselves.

yes Definately. The only mid-engined cars built by Jaguar have been race cars. As mentioned above the XJ13 was first and then in the 80's the various XJR-s were built. All of these used monocoque construction, none were spaceframe.

The only possible conection it could have with Jaguar was if it had something to do with the 'Saturday Club' which was a group of Jaguar engineers who formed the 'Special Vehicle Operations (SVO)' department. They would come in during their own time to work on unofficial projects. I'd still be surprised though if this had anythign to do with them.

My guess is someone started making an XJ13 replica but ran out of time/money/patience.

Tend to agree with groomi, probably some kind of replica?

What bodywork do you have? Perhaps if you can post some pics of the panels we might be able to point you in the right direction?

I sent the reference to America, Switzerland and to the UK to respected Jaguar specialists, people who have been involved in Jaguars and racing Jaguars since 30 years back at least. All confirm that, as I thought, this is nothing to do with Jaguar but a special. I have no idea where it came from but then Jaguar engines were often used in specials, as was the IRS. It certainly looks amateur enough. Sorry and all that. Incidentally, one even replied from the pits at Laguna Seca where he is racing his (real) D type this weekend!

as expected and as low drag confirmed, this car has nothing to do with jaguar.
This unfortunatly means its not the financial gold mine one would hope for.

A quick look at the space frame, it looks quite unsophisitcated (too heavy and unengineered) so it would have had a rather limited race life, a more likely story is that its a hillclimb special, built from a written off jag possibly e-type series 3 v12.

On to the second part of your question (what to do with it) definately restore it, if means a lot to you via family connections and is financially viable. With the growing hill climb scene race it!! with the right engine i'm sure it'd be a sucess and a least a great laugh to drive.

V12 engines are plentiful if needed, tuners too, and i would hope the car shares a number of parts with its donor car, ie suspension steering....etc, most will be excessible off the shelf from jag specialists. After shot blasting the chassis and repainting, followed by re-assembly, comes the expensive part an aluminium body built over the frame. this is very labour intensive, and skilled, but there are a few companies out there that can do the work for you. The only change i would make is the to steel wheels, replace with cast alloy jag like (like d type).

What ever you don't scrap it.

PS do you have any pics while it was running?

Ummmm.... interesting, I remember a similar chassis in Lost & Found in Classic & Sports Car a few years ago, except.... this one was in India!
This one used a Jag straight 6 old E type/XJ style DOHC & had the 4 speed all synchro box bolted to it, then a Jag IRS on that, with 2 x UJ's to couple it all up. 2 seater in front of this lot so quite long!

Very interesting & could be interested, (get behind me SATAN), PM if serious.

I agree.



Also it is not a XJ13.

Inboard brakes were used in the 60s on the E-Type and Mk X. However, to my (highly untrained) eye it looks like a transaxle which I don't think either car used.







Prepares to be corrected...

No Jag had a Transaxle, XJ13 would have but from memory that was ZF. It is unlikely to be a race transaxle either as it has synchro & helically cut gears. Only guess would be Citroen DS which would be in period & had from memory inboard discs (CX deffo had).
