My Grandad built/designed this car - Jim Keeble. Great job ! You should take it to the Gordon Keeble Owners event in June (Gunwharf Quays, Portsmouth) !
Started making them in Slough. Went bust, rest were bought and finished in Brackley Northamptonshire. The owners club meets in Brackley Market place. Remember seeing them all as a schoolboy in the 80's. Loved them ever since.
My first time seeing one these cars a very elegant GT. I particularly liked the panning shot as it gently whooshed by. Perfect for grand touring. Keep up the grand work.
Ahhh, The Gordon Keeble is beautiful. Haven't seen one of those in years. The rear lights still remind me of an Austin 1100/1300. Keep them coming Rich love it.
Yes I agree about the rear lights, my first thought was that they looked like the rear lights from my Auntie’s Morris Oxford saloon from the 60s, so I don’t think you are far wrong on that score…👍
That's the perfect car for an ev conversion having already been modified for rallying. Beautiful piece of engineering too that steering wheel centre. Top job.
As a teenager in the late sixties I enjoyed watching Wiscombe hill climb in East Devon where a Gordon Keeble would regularly compete along with two Gilberns and a couple of Ferrari 246 Dinos. Now in my 70s a Gilbern remains on my wish list. Keep on keeping these beauties alive.
Another great video, thank you Richard. I live just 8 miles from Chris' place there at Criggion. Dad was in the Royal Signals and as a kid I remember him telling me all about how he used to have to drive to the top of Criggion hill there working with the ship to shore masts.
My uncle worked at the Criggion radio station - interesting place. Made this small bit of Wales a target for anihilation in the cold war . . . Great conversion and lovely car!
This TH-cam show is miles better than the TV show, but I wish it was an hour long, there is so much involved with building these CEVs surely that would be possible
@@spudproductions7606 simple really, it's a mechanical or engineering show, and it's British not the US who have the attention span of a fish, people who will watch this kind of thing would normally want to know more rather than less, easy enough to test though, just do less cutting out and see.
When in the shop you asked what the rear lights where from. I guessed wrong, happy that you revealed the right answer. Saves me some headache. Awesome build man, very nicely done.
Bring together classic cars with a reliiable and enviromentally-friendly electric engine is something I could only dream about years ago. Great to see it becoming true.
Must admit I was a little sceptical when you announced in a previous video that you were going to convert one of only 100 GKs ever made. However, the fact that it had already been modded means it wasn't an original spec vehicle. You've done a lovely job and been sensitive to the spirit and style of the car. Please polish the rest of the steering wheel to match that beautiful centre boss.
Lovely job! I recall a few cars from the 50s & 60s that had a chromed tambour door that you could slide down to hide the radio. Have you ever thought of using a similar design to hide the touch screen (you could even have it open/close automatically when the vehicle is turned on & off)? Keep up the grand work!
I love this !!!! Im dreaming of doing my 06 old audi quatro b7 cabriolet ..Im hoping it becomes a classic..love to see how it would go electric..then it could live forever
I used to see one driving near Cupar in Fife, towing a small trailer. That must have been about 40 years ago and it regularly travelled the same road. It certainly looked special, even with its trailer, as well as being extremely rare.
Just loved watching the steering wheel emblem fit like a glove and look so good! However, I SO wish we could’ve been shown how the Tesla motor integrated with that DeDion rear end. Maybe in a future show ECC?
Where is the horn button located if it's not behind the centre cap on the steering wheel? Also I would have preferred to see that enameled to match the front badge, just my OCD.
I remember when the Gordon Keeble first made its debut in the 1960s. One of the claims made for it was that it could do the motorway speed limit (70 mph) in first gear. Now that this one has been converted, I suppose it still can..........😉
A wonderful job converting a true classic - highly desirable! Also, an excellent video - ECC would be my first choice for a conversion. Re: the steering wheel cap - I hope the car's owner isn't too OCD, because the CNC design missed the toes off the front legs! In such an otherwise fantastic vehicle, that would drive me nuts!
You and Astrophysicist Brian Cox are the only people I am aware of who pronounce tor-toise the way you do. Cracks me up. Another great conversion. I assume you get about 420km range in that so that's awesome. I was watching Stance Works in the US who is cutting up (literally) a Ferrari 308 to make a time attack car with a 1000HP Honda motor and everyone loves it. Juxtapose that with doing an EV conversion on a Ferrari and everyone looses their minds. So funny.
Remember seeing a red one at Sarisbury Green, near where they were made at Eastleigh(Southampton) Airport in the late sixties. Saw a Blue one on the M3 about 8 years ago. Number one on my wish list.
looks amazing! someone should create some molds of that body ;) it's funny watching boat building videos and car videos - in one people are removing steel and metal because it's heavy and not stiff enough and replacing it with fibreglass and carbon fibre, and in the others they're putting steel in to stiffen it all up!
It’s a nice job but slightly sacrilege on such a rare old car. The interior is nice but I don’t like the integration of the modern Bluetooth infotainment/reversing cam system. It would look nicer concealed behind a period looking speaker grille or cubby hole that could be slid or flipped out of the way when the owner wanted to use the system. I think there are at least 2 more of those WW2 radio transmitter buildings in the Breiddens/Criggion area where your machinist is located?
The Gordon Keeble is very special, nice job. Can't help but think the forward batteries are a bit hgih up but I may be wrong. The center piece almost blends into the steering wheel too much, assume that is what the original piece would've looked like? Anodized in black would be nice as well.
I was wondering about adding regenerative electric to the rear subframe of a Honda Jazz and keeping everything else the same for simplicity and long range and also to drive the aircon and the power steering & brakes. I think you would want something small and cheap that just regenerates the energy from city stop/starting rather than Tesla performance. I thought that the new electric Citroen Ami motor might do for that, but maybe 8hp & 5.5KWh is not enough? Looking at the rear suspensions of Honda Jazzes, the earlier Mk1 (2005-2008) would be easier to do than the Mk2 from 2009, because the Mk2 had the coil springs moved rearwards along the suspension arm to be aligned with the hub, which would interfere with driveshafts. Don't know about later versions.
what a beaut! You must have doubled the power of this thing? I would have guessed that this was a Bristol. I used to pour over classic car mags when I was a kid so I've seen these before. Jenson, Bristol, AC, Rover were all in the same mould of having a yank lump in a GT body. All would make great electric conversions. Actually an Interceptor would be amazing, have you done one yet?
The detail of the tortoise is a genius great car amazing story history and an brilliant future. know all we need to do is stop the fools from the toxic fossil industry from killing our Earth? try and slow anthropogenic extinction down so our children can enjoy this amazing car. Great job Electric Classic Cars. The rear lights look like a Rover P6 with a reflector. Cool car
Hello from the USA! I am interested in converting my 1960 Rolls Royce Silver Cloud to electric and wondered if you had any advice or could point me in the right direction with it. I have owned the car for over 20 yrs and I'm trying to decide if I should replace the failing engine or go electric. The engine has been removed and it's just sitting now waiting for the next step. I love what you guys do and hope I can find someone here in the U.S. that could help me. Thanks, Heath
i want so much for this conversion classics to electric to really take off. Obviously first in queue would be straight body no engine or fouled engine, but to get the beautiful shapes out there again, with more reliable and green electrics is a match made in car heaven. 60's gentleman's GT couple' is exactly the spec I would choose, too. Beauty
Awesome conversion again ! I have different conversion on my mind, I want to install Tesla 3 front seats to my 2003 VW New Beetle Cabriolet :O) Do you have any experinces putting Tesla seats to other cars? Wiring could be difficult...
In the 1970's the Scimitar was a quick car, the Middlebridge models used the more powerful 2.9 injected engine. I agree though they would make an interesting EV, but economically it would need to be a labour of love.

This looks great. my biggest worry about the big switch to electric is people not wanting to take their classics off the road. You guys are doing a great job converting these cars.
nothing better.. keep the classic car looks and style you can't improve that... but upgrade to electric...never understand anyone wanting to keep everything original.
I confess I was slightly offended when you compared the Gordon Keeble with a Shelby Cobra. The original Cobra was an obsolete AC chassis fitted with a rather nice Ford 260/289 V8. The later 427 Cobra had an improved chassis that was hamstrung by the weight of a 7 liter Ford 427 V8. Both Cobras were amazing but compromised cars to drive. The Gordon Keeble was a much more well balanced car with a chassis that was probably better designed than the later Cobra's chassis but fitted with a lighter 327 Chevy V8. I would argue that the Gordon Keeble was a superior car to Aston Martin's DB4/DB5/DB6. Pity Eon Productions didn't get a hold of one for Goldfinger.
When a farmer's trailer popped one the rear lights on my car (Chassis 61) I found that the rear cluster from a Morris 1100 was a perfect fit so it cost less that £5 for the repair.
Which chassis number is that? I don't recall one ever modified for rallying although one brave soul did race his a few times. I owned No 72 in the 80's and 90's - its sadly sitting around awaiting restoration ever since I sold it
That is a very pretty car. On the 4x4 conversions where a tesla drive unit is used to drive the original front and back axles, how does the additional gear reduction in the axles affect top speed? Thanks for all your great videos.
I just love when you endorse other people doing amazing stuff.

When in the shop you asked what the rear lights where from. I guessed wrong, happy that you revealed the right answer. Saves me some headache. Awesome build man, very nicely done.
In red or black, or maybe even green, that would be a sexy looking car.
Sweet electric, did this appear in one of bond's films? Lovely sweet
No but it did appear in a movie called "The Green Helmet" and in an episode of New Tricks

Great work sir! Just thinking about other rare marques for your EV conversions:
Gilbern Genie/Invader
Isn't that gorgeous! Proper gentleman's car and suitably improved with your conversion. Those lights look very similar to Rover P6 rear lights too.
Spud, you are a supurbe presenter, the content is pretty good too.
From brute power to solar power. A nice build, now you can come up with something for the recesses under the bumper where the exhaust pipes were.
Fantastic that owners of Classic cars are going down the electric route to extend the future of these magnificent vehicles. As always, beautiful work
Awesome moggy ive nevr herd of this car either but looks mint

We'll try to get some gratuitous under car shots in future videos. 👍
But the front paw is missing the toes - ocd triggert!
I love what you do to these classics. You make them better than the original. You the man👍👍
thank you, I'm 68 yo Yank, never heard or saw this marque before, reminds me of the Triumph Stag
Love old cars, hate having no headrests.
Perfect, Just needs a Frunk to finish it off!
Your future is guarenteed. You create beautiful work and at a perfect time. Also, how many amps does the home charger draw during a charge.
Where is the horn button located if it's not behind the centre cap on the steering wheel? Also I would have preferred to see that enameled to match the front badge, just my OCD.
I’m guessing the horn is a push button on the end of one of the column stalks ?
It's on a stalk off the right of the steering wheel. 👍
You should do a Pontiac Fiero. People love those cars but they had horrible reliability. Great cheap car for upgrade if you can find one.
I remember when the Gordon Keeble first made its debut in the 1960s. One of the claims made for it was that it could do the motorway speed limit (70 mph) in first gear. Now that this one has been converted, I suppose it still can..........😉
Does anyone else think that the front looks like an early 60s Skyline Sport?
Looks like an Aston Martin with a Renault front end.

The funny thing is you can bolt a Tesla motor in it without cutting one up and it would still beat an ICE powered time attack version. 😆😁⚡💪
@@spudproductions7606 Oh I am subscribed and I am watching don't worry about that!!
triumph vitesse front lights too :-)
That logo looks like what Certina engraves in the back of its watches
Have you converted a Gilbern yet? … Wonderful Welsh GT x
Not yet. ❤️👍
That steering wheel centre would look great enamelled.
Look at the frontend on that car "WOW" great for batteries
There might well be more space but weight then becomes an issue. You don't want to overload it. 👍
You could polish the steering to shine like the centre piece.
Supper ....frm india
I hope one day you get to redo a Stingray.
Tortoise badge ? Thelast one i saw was back in the 70s a bit like a late Bristol
Hopefully this ultra rare beaut could be put back to it's '60s form, but the environment is a bit more important!

One can only imagine how much it would have cost to convert such a unique rally car over to electric. Outstanding job!
The price on the conversion including the donor car & the custom metal work means this isn't some average joe could afford ever..
To be fair, many of the more ordinary conversions are also unaffordable.

Clear bertone styling
He did not tell us were the electric motor was placed in the car ,he just mention the battery packs

Reliant Scimitars should make a great conversion as the original V6 Ford was very heavy and not that powerful unmodified.
In the 1970's the Scimitar was a quick car, the Middlebridge models used the more powerful 2.9 injected engine.
I agree though they would make an interesting EV, but economically it would need to be a labour of love.

Yeah ive known friends who had
early 3litre models... With overdrives on the gearboxes..
All these conversions are pretty much labours of Automotive creative art at the moment .. with varying degrees of practicality but as the tech improves and the costs reduce then it becomes more viable as well as desirable.
