The "Wingfield/Walter Hill" XJ13
Good to see this car has resurfaced after a rebuild by the owners of the (formerly) discredited company JD Classics.
The Jaguar V12 – Part Three - Evolution
In Part Two we looked at the development of the quad-cam V12 – we now look at how this evolved into the first single cam V12 engine.
The Jaguar V12 – Part Two - Development
In Part 1 we looked at the origins of the V12 – in Part 2 we look at the development of the V12 in a little more detail.
The Jaguar V12 - Part One - Origins
For 25 years, between 1971 and 1996, Jaguar’s smooth and refined V12 power unit powered the Series 3 E-Type as well as a range of luxury saloons.
The Experimental Jaguar Mk10s
(The following findings are very much a “work in progress” and work is continuing in trying to fill the gaps – all contributions gratefully received!)
Team Modena Racing & Building The Legend
Finally fulfilling a destiny? "2025 will see the 60th anniversary of the year the XJ13 should have first ventured out on the world stage." "2026 will see the 60th anniversary of the year the XJ13 should have lined up on the grid of the '66 Le Mans against cars such as the mighty Ford GT40 and beautiful Ferrari P3/4 amongst other iconic classics of that era."
How many "XJ13" quad-cam V12s were built and where are they now?
A question often asked of me is, "How many prototype V12 quad-cam engines were built by Jaguar and where are they now?" As I previously reported back in May 2010, the answer is SIX. Of this six, only three progressed beyond test-bed stage and were installed in cars. A seventh engine was assembled as a 60° V8 and run on Jaguar's test bed. The V12 block for this engine was converted into a V8 using a special crankshaft with throws for only eight of the twelve cylinders. There were plans to assemble an eighth engine but it never reached the test bed stage.
Looking back ...
Summer is approaching and Building The Legend's recreation of Jaguar’s legendary 1966 XJ13 Le Mans Prototype is well underway. In 2010, UK-based Jaguar enthusiast Neville Swales unearthed the ONLY surviving complete engine built to a similar specification to the original quad-cam V12 prototype engine as first installed in the car in 1966.
Sand-Casting Bellhousings
Spent a very enjoyable and informative morning watching the first of my bellhousings being sand cast. Having decided to produce a limited run of "customer cars" built using the same tools, techniques and the same meticulous level of detail as the first car, I needed to have a batch of bellhousings made.
XJ13 - Building the Chassis/Monocoque - Choice of Materials
As the build of my first XJ13 monocoque/chassis progressed, I wanted to consider the materials that should be used for construction of the component parts of my re-creations. Jaguar themselves went through a similar exercise in 1964 when the XJ13 had reached an advanced design stage.
