- In this Rare Cars documentary, we go in depth into the history of the one and only Jaguar XJ13, the experimental prototype car from Jaguar that was designed to compete and win at the 24 hours of Le Mans.
Few people even know that this car ever existed! And while information on this car is not super easy to come across, we were able to at least put together this quite documentary video on the XJ13, so enjoy this crash course into one of the rarest racecars of all time!
Note, we are NOT historians. If we got a fact wrong in our video please let us know!

Should've included the sound of it being driven
Incredible that the soundtrack wasn't regarded relevant
It would’ve been better than listening to him endlessly repeating XJ13 and pronouncing Jaguar the American way. It’s a British car, so pronounce it the British way.
This gave me the “fizz” mixed with the melancholia of what might have been. th-cam.com/video/e6xT6Mkwe4Y/w-d-xo.html
No sound = BS car review. See the pretty pictures.
He likes listening to himself talking.
It's pronounced jag you are. It's English, not Mexican.
that is quite literally an e-type supercar... absolutely stunning, they should've built the 50 just on that alone. such an elegantly gorgeous automobile.
Breathtakingly stunning isn't it
@@zopEnglandzip Has been described as reptilian like a crocodile and as much as I like it, that comment does strike a chord, can't you image it hiding in a nearby bush ready to attack a passing Ferrari and perform the death roll!
Not very practical, 38 inches tall at the top of the windsceen, four inches ground clearance, coolant pipes running along the passenger side of the cockpit, fuel crossover lines running through the cockpit (protected), Marsden flexible fuel bladders in the sills (mostly blocked off now, I think), offset steering wheel, had to be modified when being restored, Lofty England wanted to fit in it and that was that.
But YES, the ultimate example of Malcolm Sayer's artwork. Apparently there were no bodyline drawings sent to fabrication, a set of co-ordinates and specifications for mathematically determined curves was sent instead (sounds plausible), Sayer was fond of ellipses.
FFS it's jagUar not jagWar!
Why is it that Americans can't pronounce Jaguar properly?
Not 1 second of the amazing noise this beautiful machine makes?
Brits can't pronounce it right either. It's pronounced hahg-whar.
@@deruberschwarze3943
😅😅 Good point,
@@deruberschwarze3943 No it’s not. Brits created that car and also the language so it ‘jag u are.
They cant pronounce a lot of car brands properly.
@@paulfitzgerald7513Brit here and you are talking nonsense. “Jaguar” is not an English word, it is native South American. Spanish/Portuguese speakers are likely closer than either the British or American pronunciation.
One of the most beautiful cars ever made, and my all time favourite. 👍
True, a very slippery car, but if they had tried to race it at 180-200 mph, they would have found horrendous lift, as Ford learned in 1964. Hence the droop snouts and rear deck spoilers of GT40s.
The engine of the XJ13 is not based on two XJ6 engines on a common crank case. It's an entirely new engine. The valves are on a much narrower included angle, and the inlet ports pass between the two cams. A small number of prototype 4-cam engines were made for testing, but only two are known to exist. One is in the car. Another one appeared on German E-bay a few years ago, and is now in a replica XJ13 car built by Neville Swales.
i thought someone in America had the block that was used for the 60 degree V8 study, but whole engines, two out of five, it could have been worse.
Possibly the most beautiful car ever. Thankyou!
You got to learn how to pronounce Jag-U-are..that how its pronounced.. It is not a Jag-wharr
A couple of corrections; the work actually began in 1962, engine testing began in 64. Jaguar first looked at a V12 unit way back in the very early Fifties, and a while later there was a wooden block with a couple of XK heads on top at one point. This, along with the company working on the Meteor tank engine, possibly helped fuel the rumours of Jaguar developing a V12 for many years before the XJ13 programme. But anyway, the actual 'proper' V12 was a clean sheet and not a couple of XK units. Finally, the engines were originally developed using Lucas fuel injection, the use of carbs came a little later during development.
I was fortunate enough to have seen this car in the U.S. at an Historic Festival at Lime Rock Park some 8 or ten years back. It was displayed only, never on the track. When I first saw it, I immediately thought it must be a replica but checked it out anyway. To my astonishment, I found out it was the original prototype and checked it out thoroughly. Ferrari and some others have definitely made some exquisite looking cars, but this machine is at the top of the list for the most beautiful looking racing machine ever built. Also, no picture of it has the same impact on you as seeing it in real life does, and that is for damn sure! Simply magnificent!
I agree with all you said and can add some... it first appeared after many years at the Historics at LS in 92 or 3. I took many pictures of it as it was so beautiful and they ran it and the engine note was fantabulous. I have the AutoArt 1/24 model and lust at it daily.
It currently resides at the British museum in Gaydon, UK. Went a couple of months ago and was lucky to see it as was one of my favourite cars in gran turismo. Took loads of photos and run my hand over the car. Made my week
Take a deep breath - and say Jag - u- ar. I don't know what a Jaaaaggwaaar is!
They never got 550hp out of it, I think it went to a bit over 500 but 550 was considered quite doable.
Norman Dewis was ordered to keep the car at a reasonably low speed as the engineers were wary of the condition of the wheels and tires. It had laid dormant for some years. However, Norman wanted to break the unofficial MIRA record set by David Hobbs (a Jaguar apprentice) some years earlier in the car and thus the disaster unfolded.
The engine was okay but was following a dead end in head design with the inlet ports entering between the camshafts, if memory serves early Lamborgini engines also used this design. Initially, the ports were too straight and the engine had insufficient swirl and tumble.
They built 5 engines for the car - they were all different, at least one utilized an open deck design. The car became a test bed. Some of the engines were also run in Mk10 Jaguar road cars with carbies to test their suitability for road use.
I will cut it short.
if you want to hear the car, here is a link to a video a few seconds before the XJ13 is featured, but I recommend you watch this hour long video from the start. It is the Jaguar episode from the "Victory By Design" series with Alain de Cadenet, a Le Mans racer who did 15 seasons. After a while, you will wonder how they managed to get hold of all those impossibly rare cars (spoiler, he drives more than one Le Mans winning car, and I mean DRIVE! And then wonder even more how he was game to push these irreplaceable cars so hard. What becomes clear early on is how fantastic a highly tuned XK engine sounds and it just gets better when he hits the 12s, even the XJ220C sounds pretty good.

There are a few other episodes and highlights on youtube but get the series on video if you can , it will blow you away, and yes he does American rarities as well.
Your link took me to the start of the video, and I watched the whole thing. I'll attempt to link to the bit featuring the XJ13:
th-cam.com/video/DRoNxWRm-kQ/w-d-xo.html
A while ago, I heard whispers that E1a was being rebuilt. Is that true?
I interviewed Norman Dewis some years ago for a leaflet that I was writing for the Jaguar Daimler Heritage Trust. Norman told me that the filming was done at the MIRA test track in the English midlands for the launch of the Jaguar XJ12. He said they'd pretty much finished but the director of the film wanted just one last, fast, passing shot. It was while he was out on track for that shot that a wheel collapsed and Norman ended up in the infield, the car having rolled.
@@sky33liner The first Jaguar car to get their production V-12 was the Series 3 E-type. I always understood that the filming of the XJ-13 was for publicity for the release of that car, not the XJ-12.
Thank you. Yes, the "Victory by Design" series was fabulous and as you say, it's quite something how Alain de Cadenet pushes these impossibly rare and priceless cars around, in the manner for which they were intended! Fantastic stuff - I might have to watch one episode tonight! Cheers - David
Its a Jaguar, not a Jagwar! Why do Americans insist on miss pronunciation of the English language?
You mean mispronunciation, surely.
Show me the hidden I in Aluminum. I'll wait. It's Aloominum. Not Aloominum lol
Y'all invited the language, but y'all are dah ones who can't speak it right.
Beautiful Car that never raced, so no, it's not a GT40 killer. Neither was the Cheetah. Too funny.
Shame on Jaguar for not making at least 50 of these beauties! They would have been the pinnacle of homologation heaven.
If you are going to make a video about a car brand, it helps if you can actually pronounce the brands name:
It is NOT "Jag-WAAAAAAAAAAAAH".
It's Jag-U-Ar
Not difficult is it? The clues in the name
WOW fucking beautiful
Please oh please, listen to some British channels so that you can learn how to actually pronounce the word "Jaguar". It is NOT JagWahh!
Whats up with all these cars that were built to chase down the GT 40 and the AC Cobra?? Its almost like Carrol Shelby was the best all around.
Always looked like a very happy little car! You need vehicle sounds. Pause the yapping once in a while and let us hear the cars.
bloody hell ; how many times are you going to say JAG-U-AR wrong !
It's an English car. The pronunciation is Jag-you-are.
Stunning car, now you just need to learn how to pronounce 'Jagwaaaar.'
So GT40 killer is not really an accurate description for this car.
Yeah, I think the GT40 would have beaten it but we will never know.
It is very beautiful
Any chance of hearing the sound of it
Search on here for “jaguar xj13 - victory by design”
It's currently on display at the British Car Museum near Banbury, UK. Well worth a visit if you are in the area.
No way that is awesome, next time I am in England I will definitely have to pay that place a visit! Thanks for that
For those who have followed the XJ13 vs GT40 debate, Norman Swales has extracted some information from the Heritage Trust paperwork on this very issue. In 1966, Jaguar managed to obtain a GT40, albeit a road version, From Ford Advance Vehicles to do some comparisons. An interesting situation, you would have thought that would have been the last thing Ford would have wanted to do. There are also Silverstone lap times for XJ13 and these are compared to the best contemporary GT40 times. It appears the car was more competitive than I thought and Jaguar was confident they could have significantly reduced the prototypé's weight to make it more competitive. I find this interesting as it is usually the other way around, with later cars getting heavier. Mind you the crash showed just how strong the chassis was, it was still straight to within a few millimeters, despite being rolled and flipped, so obviously overbuilt, to Colin Chapman, it would have been massively overbuilt. It must have been one of a few if not the only car using a full monocoque with stressed engine at the time, but i have not checked this, so I could be wrong.
Unfortunately, the V12 would have been limited to about 550hp (that bloody downdraft porting), and at the time the Jaguar racing department was very small, and Bill Lyons was trying to sell the company to the dark side, a very sad outcome. Downdraft porting was really a dead end, the game changed completely with Harry Westlake closely followed by Keith Duckworth. Four-valve heads were back in, and finally, with a rough idea of how important squish is, the modern combustion chamber came into existence.
Also, this blog clearly identified that the crash was caused by a plugged tire (apparently It had a slow leak) failing after Norman Dewis ignored instructions about keeping the speed down.

Keep hearing about all these Corvette's and euro cars that are GT 40, cobra , and mustang killers but I can't find any of them in the record books a European car with working head lights would be a marvel
I keep hearing Americans hating on Euro's but then I look at auction prices and see Americans paying tens of millions for the best , most famous racing cars of the past - which are of course European
I saw this running and yup maybe, it could have been and it wasn’t a fücking Jagwaaaaar!
The FISA Rules for racing categories were world wide and stringent for many forms such as Sportscar, it was called Homologation and the design had to include provision for one passenger and a spare wheel, following early forms of car racing from the early 1900s when the French controlled the sport.
Gorgeous. Would Love to have heard it.
I have a 1/18 XJ13 in my small car model collection. It is simply beautiful
One of the best looking cars ever!
Reminds me of the secret racer called Melange in an episode of speed Racer its shape the color the engine layout
The animators lifted story lines & car styles straight from the era the Mach 5 & Racer X cars both from earlier Ferrari's
My brother built a high end replica of this... sort of. It's a carbon fiber body, on an all-out Aluminum race tub. Fir example it sports 6 piston front brakes with provisions for a 2nd set of calipers. 12 piston brakes at each wheel seems... excessive, especially with a mild build of Jaguars 5.3l V-12 (say, 450-ish HP, but torque is 430 lb/feet on a 1700 pound w/fluids racer. Also that engine is bulletproof, and looks sick with12 throttle bodies and polished velocity stacks. He shows it occasionally in Richmond VA area. Love that he got Norman Dewis to sign a piece of metal when he met him in 2018, and has it on the car. Norman is the guy who flipped the original car in 1971 at the MIRA high-speed circuit while filming to promote the new V-12 E-type.
When you cant win on performance technoligy, CHANGE THE RULES 😡
how many times have we seen this before n raceing? to many to count. 🤠
Surely someone will make replicas hint hint hint lol
About the Ford GT40; the US made (LA-based Holman-Moody built all the 7.0L Mk2`s) Mk2 was equipped with Fords 427R 7.0L raceengine, oficcialy hp-numbers was 485hp at 6200rpm witch was true enough. But the true shiftpoints was at 7400rpms where it made "a bit more" even with a midrise intake as in the GT40
Cars of this age actually had signature looks to the brand
Your intro is completely bogus. "Jaguar not near the top of the most iconic sports cars of the 1960s"
Car people might be able to spot a Ferrari 250 GTO or a Miura.
But EVERYONE knows what a Jaguar E-Type is, and LITERALLY EVERYONE will be able to look at a DB5 and go "That is an Aston Martin."
Why do people always diminish the British car Industry in terms of having good things? Could it be that they are salty that it produced unmatched and unparallelled icons to the point where they are considered not to be icons by some irrelevant dude on the internet to be used as some narrative device to introduce an interesting car?
The Le Mans rule change took place in 1967, just after Ford had won for the second time with the 7 litre Mk 4 (GT40). The rules did allow for up to 5 litres to race there if 25 cars had been built. Hence two more GT40 mk 1 victories in 1968/9 and the two Porsche 917 victories in 1970/71, their first outright wins.
You are such an expert that at 0.06 while you talk about Jaguars you place a Blue Lamborghini 350 GT! OMG!
I dont get it, how is it reasonable, in a 'prototype' class, that the manufacturer must have 50 road going versions to qualify for racing? If there are 50 road going versions then it's NOT a prototype!
I remember when Rockstar games added the Swinger to Grand Theft Auto. I was trying to google this Jag only to have a hybrid strain of cannabis be the first result.
You know., Sherlock does not know everything, particularly in video editing.
But it leaked too much oil and they could never seem to find where it was coming from. (Although… totally cool looking)
Behave the e type is up there with the Lamborghini muira and. Ferrari 250 with iconic cars from the sixties maybe not as quick but just as stunning looking
Curse you,, No Glorious soundtrack?? Drats and triple Drats 🤬🤬🤬😄
The GT40 wasn't a Ford. It was a Lola MK6 with a truck engine.
Nice video although the history is missing a bit. Jaguar had already won Le Mans five times before building this car.
It is NOT pronounced "Jag-wire" - look it up. Great story.
yeop, I'm gonna be that guy..
it's pronounced "porshuh"!
Stew Jones Jaguar in Winsted, CT has a customer's tribute car in his shop.
It's a Jag-u-are, not Jagwaaar
Should have been called the XJ12 - then it wouldn't have been so unlucky!
Grill looks like a catfish mouth, and this particular thumbnail angle of the car made it look ugly unfortunately
Looks like they never heard of flush riveting, all those rivets detract from appearance and adds drag.
Great video on a (potentially) great car. It is beautiful though with a boat tail from the era before the cam tail took over.
1st ive heard of this and im a car nut. Good job.
Now L88 aluminum 427 corvette or the 1 big block 65 chevelle or ...
I will say that for sure one of those is on our list!
Would love the history of the hemi/firedome, every time i check theres a smaller and smaller 1.
Or ZL-1 427 which was aluminum. L-88 just had alum heads.
Havd you ever thought of doing a video on the 1 of 1 Tickford Triumph Stag?
the real XJ13 was a 4 cam v8 = not the single overhead cam = like your showing ! = yo !
Correct, thank you.
Litty
Awesome documentary!
+ 1 New Subscriber!
Pretty sure there's an XJ13 kit car out there, so if you want one get googling
Would have been interesting to see that Jag at Lemans against Ford, Ferrari,and Porsche.
Right!?
Incredibly sexy looking machine 😅
My favorite car from the 60s. I read that the rims were obtained and made from castings for the development aircraft for the SST. There is a fiberglass kit car being made for this as well, called the RCR XJ13.
The big crash at MIRA, damaged the wheels (two I think), so when it came to restore it, they scoured specs and warehouses and found that they could machine new outer rims from existing wheels of the same alloy, Concorde wheels. The wheels were machined to the correct shape and welded to the remaining original section.
I will have to find a book I have, but I am sure there was a story about Lofty England driving X13 a bit too spirited at Silverstone and the engineers giving him a right royal dressing down to be so stupid to drive a car at that speed on welded rims.
Rod Tempero in New Zealand can build you a metal one with hand formed aluminium panels etc... that looks just like the original although the engine options may not include the original V12. I was amazed how good it looked in the flesh.
Looks like a second gen ( if they made one) XKSS
It’s spelt Jaguar, it’s also pronounced jaguar. Not “jagwaaar”.
The same hold true for dual. It’s not pronounced “dooool”.😒
It's a Spanish word - it's pronounced hagwaar. How do you pronounce Paris? Well, you're wrong.
I always thought this was the most beautiful Jaguar, with the D-type XKSS being a close second.
In another video one of the drivers describes the seating position and driving experience in the XJ13 as being simply awful even for small drivers. Basically just wedged in with little concern for even simple ergonomics. It seems any faithful reproduction would have the same problem.
Can you do an episode on the Roy Lonberger creation Chevrolet Astro 1 from 1966 ? It was a "secret" project by GM designers, who actually were not allowed to develop race cars but managed to hide away the 36 inch "high" car as a "study in aerodynamics" for the beancounters of the company. Intended for the 24 hours of Le Mans, it never made it to that race, but was one of the star attractions of a late 1960's automotive fair in New York, after Larry Shinoda equipped the secret race car with elevating seats. The car has been immortalized by Corgi Toys and was one of my absolute favorite ones as a kid. Little did I know then that I would be in e-mail contact with the original designer....
Certainly was a quiet engine. (sarc.) Was there some sort of embargo on playing the sound.? A wasted opportunity.

A clip from another "Victory by Design" episode, an American car, not really all that rare, but...
th-cam.com/video/tXnh2CRQCbc/w-d-xo.html
Thank you for describing the engine as being two straight-sixes 'mated to a common crankshaft.' So many idiots say 'welded together' thinking they're being clever or funny; or even just say it without thinking. It is the mark of quality to describe things sensibly.
If it had been 2 inline 6 XK engines of the time it would have sure;y been 7.6 or 8.4 litre as te production engines were generally 6 cylinder 3.8 or 4.2 litre!
Had Jaguar gone through with the racing program, the XJ13 would have made a gorgeous longtail coupe for Le Mans...
Never loved the "love it or hate it" E-type, but THIS here was a clean machine with gorgious looks.
I think this vid, whilst very good, mistakes sports cars with grand tourers. If think in a list of 60’s iconic cars the E type is up there with all the others.
“GT-40 killer”. Lmao
I remember seeing in a car magazine, an engineer in Australia hand built one in 80s I think... worked out specs and completed car.
Black.
Car probably looked amazing in black
I think that’s the one I’ve seen at Philip island historic race
@@widewan7585 He ran the Targa Tassy at least once but kept slow, didn't want to damage all that work
This car was one of one, and this isn't it! The hazy footage is of the original, but the recent footage is of a replica
Yes, the footage is of both. Hard to find enough content on the car that’s good!
AND THE NAME IS PORSCHE, NOT PORSH!!!!!
GT40 killer is a bit rich.. it was unbelievably unstable at high speeds.
Do you have a source for that claim? Preferably a primary source or link.
The XJ13 design was extensively wind tunnel tested, one of the wooden scale models was found in storage at the wind tunnel. There is some suggestion that the entire car was also wind tunnel tested, but I do not have a primary source for that.
Malcolm Sayer did a number of design studies on mid engined V12 cars after XJ13. One of these was, if memory serves, for a road-going, mid-engined, V12, road car. This design study had the buttressed low-pressure zone behind the cockpit, apparently to improve high-speed stability (this was, in a different form, mashed into the XJS design), however this car was radically different in style and fitted more with the period, that is, it looked, ... well... not great.
Logically, this does not imply XJ13 was unstable, the above design study would have had a focus on a simpler build process, just like the road going V12 was designed for a very simple build process.
I saw a replica of one of these in Adelaide Australia formula 1gp in late 80s sounded great. But racing at our local hill climbs I can't help but remember another rare race car of this era the "Healey lemans" super cool
What a beautiful car! Yes, the sound would have been the icing on the cake.
describing an iconic race car without any sound from it is the most dissatisfying thing you can imagine when choosing a video
th-cam.com/video/B_Ra6Ip1AhU/w-d-xo.html
That car has the happiest 'face' I've ever seen.
It does have a smile haha
… you lost me at Jag-wire
This is serious car porn. 5 out of 5
I swear a car that looked like that was atvthe auction in Pebble Beach some years ago at the main convention center.
Fools should've mass produced it in a street version. Screw the racing! It was Malcolm Sayer's masterpiece: the superlative sculpture on wheels.
It was always part of the folk law that it was kept secret as if shown it would hurt E-Type sales as everyone would be waiting for a mid-engined V12 road car, something that was not going to happen. Malcolm Sayer did some design studies on such a road car, it did not look like X13 but had a long flat rear deck with two buttresses to generate a low pressure zone to stabilize it at speed. Of course, some clot nicked that part of the design and welded a much shorter and narrower version of it to the XJS. Interestingly, they found the wooden model he used to test the aerodynamics of XJ13 in storage at the wind tunnel he used.
When the "building the legend" replica was being built, they also found out that the original molds for the windscreen were still extant so had a new one made. When jaguar had the car restores, it was fitted with a plastic windscreen, I suppose no one thought the original molds would still be available.
Could Jaguar make a Jaguar look better than an E type? Heck yes
Right!
That was not a Gemballa Avalanche
One of Jaguar’s finest efforts, doff’s cap, well done indeed ✌️🇺🇸
Thanks. A car I've never heard of.
Glad you enjoyed!
There were no gt 40 killers.
Them some sweet curves on that car,kinda like an e type on steroids
Beautiful car..
Too bad
THAT JAGUAR COULD NEVER DEFEAT ANY GENERATION OF THE FORD GT CARS !!!!
So where is that portal into an alternate dimension where alternate histories can be tested?
If you don't mind 1:1 replicas, you can find British built decent quality firms manufacturing these.
I think those 1:1 replicas are super great, the more of these cars on the road the better. Those replicas are also lots of the time really good so they are a nice homage to the real one
Part of your footage is a replica. It’s a car owned by Aaron Lewis.
Cool video
Thank you!
