Straight Up : I work at Ford and the diagrams and information provided to me are subpar, these videos have been a valuable resource. Kudos for great educational delivery and for being an icon of diversity
Unbelievable. John, you are so easy to follow you make me wish I would have pursued a career in automotive work. Thank you for sharing your passion and knowledge.
Bro is a straight beast! In a wheelchair and handling this by himself and seems super calm. Great video! I'll never do this but it's great to watch and see exactly what's all there and involved.
As a Mach-E GT Performance Edition owner who had his HVBJB fail, this is the level of care and expertise that I hope the dealer technicians are using with my car. Thank you for sharing these videos.
Trying to get my 16 yr old to take a class such as this. If we got super lucky he would land in your class. These are the cars our kids will be working on when they have kids to support of their own. You truly are teaching the future. Thank you
Thank you professor for taking your time to create these excellent videos for free to the public. This is the level of excellent knowledge and instruction that trade schools everywhere should be taking hints from, especially as the automotive technician industry moves towards needing to incorporate more in depth training regarding EVs.
Wow, three lessons in less than a week. Thank you professor! This is the only place on Internet where common people like us can learn such things. This channel is invaluable. By the way. I've had a question for very long time. When you created this channel, was it mainly for teaching your students and maybe offering them review lessons or did you already had in mind that many other people like us would be interested? Why exactly did you create this channel? I'm asking just because I can see that filming and editing is a huge work, and to me it's just amazing that a true expert like you would give to the world such extremely detailed lessons which require hours of preparation and work.
Thank you very much! I started the channel as a place to store the videos I made for my students. I had no idea that anyone else would be interested in them. Today the videos still serve my students, but now I am also aware I have a large following from around the world.
Great stuff. i really appreciate the level of detail. I've been following your videos forever (well, for years). I don't know if I have ever mentioned the wonderful example you set by doing the hard work yourself. You don't cut corners. No whining, you just do it. The example you set is meaningful. It also makes me feel guilty for putting off looking at the leaking windshield washer fluid coming from my wife's Subaru. Sending you an email on a different subject you may find interesting.
Many thanks for your videos. I just purchased a Mach-E GT, and I learned so much about how these vehicles operate. Thanks again for all the technical commentary-love it!!
Your experience with this procedure almost mirrors mine when removing it for the first time. Getting the car positioned just right may as well be an act of Congress. VERY difficult, and can be made worse if you have an older lift with less arm flexibility. Some old lifts with two stage arms can't even lift these. The coolant clips are a pain, and I fear how difficult they will be to remove with some dirt and grime built up. The diagram you found from the supplier is very helpful looks like. I think the offset center of gravity is why the Ford lift table is HUGE. The lift surface is probably 4 feet by 5 feet, and the lift itself weighs something like 800 pounds. Very heavy duty, it was overbuilt to work for future larger packs in upcoming vehicles.
Nope - I don’t ever think your videos ate “long enough”! Great stuff. Those coolant hose connectors look very interesting. Assuming they’re handled properly, of course. Hopefully they make that satisfying ‘click’ when positively engaged/disengaged. Ahh…
Hello Professor from New Zealand. I'm not sure when we will get these cars or if at all!. We do have a Tesla dealer. Fascinating videos, may thanks for them. I do hope younger automotive mechanics follow some of this, because this is where we are heading. I have 3 Hybrid cars myself and various mechanical service people I take them to have no idea of the technology or dangers involved. Your videos are free (pretty much) and filled with priceless knowledge. Well done. Look forward to the next ones.
Welcome back professor 🙂,I really miss your classes and during my diploma in automobile engineering I watch your video on Ev and In India the automobile company Focus on EV and I hope this will help me. By the way, Thanks a lot professor 🙂
Very informative, looking forward to the rest of the series, do you know which contactors are sticking in the ford recall, as ford says to avoid repeated hard acceleration, and to avoid dc fast charging while waiting for the software fix. I was hoping to see a common contactor between the dc fasting charging and the battery voltage. Thanks for your time. I'm a retired fleet mechanic, and current owner of a Mach-e extended range gt
@@Nicholas-f5 Recalls have been part of the automotive trade for years, this one seams minor compared to some of the others. I'm sure that future production models will get better. John has shown that the replacement of the contactor module, is not that hard of a fix, and if need after warranty, I would not hesitate to do this repair my self. My wife's mach-e has been a good vehicle to this point 20 k so far, and I enjoy learning the new technology. Thanks for the reply Nicholas
HI John you were taking about how hard it was to position the car with the special adaptor I was thinking why don't you use 4 wheel jack dolly some are mechanical and others are hydraulic in my shop I have 2 of them but for your application you would need 4 of them I use them to lift the front end of car that are too low for me to get on my lift but for u it would be nice so you can move the car in all direction even if the car is in park plus it would lift the car a bit more so it would make it easier to put the adaptor on the body of the car plus it's nice to use those dolly if a car is broken or you want to push it against a wall to save space in the work shop or like if you have a car with a bad air suspension and the car is too low to get it on a lift especially a car.
Professor Kelly Thank you! Did I miss how to drain the coolant loops? I thought I watched all the way to the end of part 2. And I'm only 25 minutes into part 3. I'd suspect coolant changes would be a maintenance item, that could be done at home with a Mitivac air vacuum filler system? As a engineer not in the automotive field, thanks for explaining the scientific detail of how and why your doing each step of the process.
Good catch. I forgot to video disconnecting the hoses at the front of the battery. Disconnecting the two battery coolant hoses at the front of the battery drains the battery coolant expansion tank. Disconnecting the two rear inverter coolant hoses at the front or rear of the battery housing drains the motor electronics coolant expansion tank. I use the Mityvac vacuum refilling system, it works well. I will demonstrate it in a future video after reinstalling the battery. Thanks for watching
@@WeberAuto Thanks! I'm either going to have a Ford Lightning or Mach E soon in the garage. Great to see Ford willing to collaborate with Universities to share technical knowledge. It seems like their more willing than others to share serviceability information. Helping potentially grow what might become the independent EV technician population of the future. Allowing customers to not always have to rely on limited dealership service for repairs.
Excellent video, very good explanation! Thank you very much for the information, you are excellent teaching step by step security methods, architecture, measurement, diagnosis, reprogramming. Excellent!!! Many thanks. Greetings from Uruguay.
My wife is probably watching Survivor or something and thinks I'm crazy for wanting to learn all I can before I get my Ford Lightning ! Being a mechanic for 30 plus years, I am absolutely loving watching your incredibly well done videos. never thought I would go electric but what I have learned from you I feel much more confident even though I'll have to keep my old suburban so I have something to fix. I sure hope some tech videos of the Ford Lightning will be coming ! Are the cels 4680's ? or a completely different type
Currently, only Tesla is using 4680 cells as far as I know. Tesla has their tabless dry electrode 4680, and Panasonic is making a 5-tab wet electrode version. These Ford cells are similar to the Nissan leaf, Chevy bolt etc. But the chemistry is different.
"4680" is a just a size of cylindrical cell (46 millimetres in diameter by 80 millimetres long). Most EV manufacturers do not use cylindrical cells at all - as in this vehicle, they use rectangular pouch cells that are stacked into rectangular boxes (modules).
Professor Kelly, I hope you don’t mind me asking you a question off topic from your video. I’m a full time wheelchair user and am looking at getting a new BraunAbility side entry XT power ramp van (I transfer from my wheelchair to the van seat). But, I need to be able to pull a small trailer (Scoota Trailer, 1,000 lbs GVWR). I’m wanting to get a 2021/2022 Toyota Sienna hybrid van. The BraunAbility website states that although they don’t sell them with a tow package you can have a Toyota dealership install one once you purchase the van. My local Toyota dealer has said they will install it for me if I get the Sienna and it’s possible. However, my local mobility dealer doesn’t recommend pulling a trailer with the BraunAbility converted Toyota Sienna, but isn’t giving me a reason other than BraunAbility doesn’t sell them with it being installed. If I don’t get the Sienna my next choice would be a Chrysler Pacifica as BraunAbility does sell them with the trailer hitch installed. However, their are many reason on why I think the Sienna would be a better vehicle for me. You know the eCVT Toyota uses very well and being a fellow wheelchair user I’m hoping you are familiar with the BraunAbility side entry minivan conversions. Do you think it would be ok to pull a small trailer with the BraunAbility converted Toyota Sienna or should I look at the Pacifica?
Hi Dan, I drive a 2020 Sienna van (Braunability side entry conversion). I like the Sienna because it has the tallest roof and widest opening. I also like the reliability of Toyota products. I do not know if a Toyota trailer hitch will bolt on to a converted van. You may need to get a custom hitch manufactured. Best wishes.
Professor Kelly, does the cooling system for the drive unit and inverter have a thermostat or does the coolant pump cycle on and off to maintain proper operating temperature for these components? Thanks for sharing your knowledge.
Amother famtastic video professor! What is the book time on removing the battery? Would you consider this process easier than pulling the cab on a ford truck?
I have had three of these cars. When I had issues (on first two cars) we visited five different Ford dealerships that (all) told me that they had NO IDEA how to work on my mach-E.
I'm suprzed to see no lock-tight thread type sealant on the threads of the Batt bolts... you see in the automotive industry, on Subaru brake caliper setup they use a lot of the time.
This looks very similar in design concept to the Chevy Bolt battery pack, just a little larger. I assume the Toyota BZ4X and Tesla battery packs are about the same, except Tesla use cylindrical instead of rectangular cells.
It looked fine to me. The bottom appears to be thin aluminum. There is an inspection procedure to check for damage that might damage the battery modules. Stay on pavement.
Really interesting tear down. I’ve read that there is a weakness in the battery that prevents more than 5 seconds at full power. Is this something you have identified during the tear down? I’d be interested to hear your view on this issue.
The Mach-E GT has a nominal rating for the fuses of 630A (Rear Motor) and 350A (Front Motor). They are pushing the limits with a current draw of 1050 amps during full acceleration. I suspect the fuse sizes, contactor sizes, and maximum allowed current needed to be better calibrated to avoid overheating the contactors (A possible reason for the five-second power limit). I will be surprised if the junction block with contactors and fuses gets replaced due to the recall for the contactor issue.
Professor . So if the 12V battery is disconnected...The HV system is out of order. Same with the interlock. Some remarks from a former diagnostic technician with 35yrs of experience with MB cars . That green plug disconnector .....use a padlock instead of a simple carabiner. Second , if disconnecting the minus pole of the battery ...put a plastic cap on the minus pole cause that thick cable has a "memory" and can bent back to its former position . Regards from Belgium .
Don't know if anybody else has asked this question. Would it be possible to put an extended range battery in a 22 select all wheel drive? I see there now available in the 2024 model as an option. If this would be possible what would it entail and what would it cost? Do you think you could use a salvage battery if the battery is not damaged. I've seen a lot of totaled Mach Es available online. Total isn't what you might think some of them have what looks like very minor damage. Nowadays are totaling cars out if the airbags are deployed.
@35:23 the energy capacity rating is in kilowatt-hours, not kilowatts. Prof. Kelly knows this - it's just a slip; my comment is only to correct any confusion by viewers.
Most torque to yield bolts in most applications can be used up to 5 times. Now this is never recommended to to but I bet if you read the fine print in the ford service manual it will allow more than a one time use.
Professor, I’m curious what the reasoning is for buying the particular trim of the vehicles you purchase. With the model S you have, I believe it is the highest trim (Performance dual motor). The Mach-E is the GT model. I’m just curious why the college purchase these more expensive models, vs something like the Mach-E4x or the Model S long range. I can understand wanting to get the big battery, dual motor versions, but why the performance models? Thanks for another great video!
Good question. I learned from purchasing our 2017 Bolt EV without all the options (DC Fast Charge) that limited myself from showing my students all of the latest and essential to understand technology. I will always try to purchase the fully loaded versions of these vehicle for educational purposes.
Professor, I have a question. Are these batteries officially serviceable for repairs? Let's say a cell goes bad and the car tells me to contact a Ford dealership for repair. Would they change just the bad cell, the entire module or even the whole battery? And what about the contractors or the battery management module? I'm asking because I frequently hear that battery problems in electric vehicles often requires (officially) a full battery swap. But the inside of a battery is so modular that it seems fairly easy to swap just the faulty component.
Yep, there's a battery balancing procedure that may need to be performed. Unlike the Tesla packs, which are a lot less repairable. The structural battery in the new Tesla model y isn't repairable at all.
@@WeberAuto So then its possible to change any individule cells that may be bad by removing the module & testing each cell. Thats the key to keeping a EV affordable.
@@mikemiller659 Tesla are aiming to make 20 million/yr by 2030. No way to do that with traditional manufacturing and repair perceptions. Drivers in this crisis are lower cost by design and ease of manufacturing. This runs through all modern manufacturing technologies. Tesla have found modules to be redundant given the low rate of pack failures. In the third row interviews musk talked about the Roadster needing modules because of nascent battery technology and from then on it went unchallenged until the Model Y.
you are my favorite EV specialist I would like to know what is your opinion on battery pack serviceability of Tesla vs Ford, VW ,Audi,Porsche, Hundai, KIA etc... especially the new 4680 cell form factor I would like you if you can make a video on this topic I think it really important when the cars are going to be older and any replacement of any component could be done even used parts like contactor BMS modules etc. but if the battery is made like Tesla you can't even repurposed batteries for solar or any other EV other than using the complete battery pack are you going to get a VW ID4 ? . the way the top cover is removed compared to the top cover of the new Tesla pack see Munro live it's one of the last video it totally a disaster I don't like it.
This couldn't be more different from a Tesla battery pack, especially the structural 4680 pack that Munro is dissecting, where everything is glued together with polyurethane. Also the new Model S/X battery, which has none of the open space seen in the Ford's pack.
This is true. Tesla packs are notoriously difficult or even impossible to service. That makes them effectivly disposable. Unfortunate. Ford by design intent made their pack easy to service. In the event of a single failed cell a pack can be replaced without replacing the whole battery. GM has gone one step further, making the pack BMS reprogrammable so that cells could be replaced with some unknown future chemistry to prolong the life of the vehicle. Tesla's disposable batteries should be cause for investors and owners to complain. It is little different from Apple's new phones where battery replacement is prohibited by the phone's software.
@@Miata822 amen! On the Tesla battery, if a single 4680 cell goes bad, the entire multi-thousand dollar battery has to be scrapped and replaced. Absolutely no serviceability. Almost every other manufacturer splits the battery into smaller, serviceable modules so that just the failed module can be replaced for a far less expensive and wasteful repair. Tesla forces you to replace the entire thing.
Yet so many electric vehicle backers think they are going to have quick change battery shops instead of having to charge the batteries. There is nothing quick change about it.
Excellent video. Imagine the problems in service work at the dealer with Mech./Techs. that can't find their ass with both hands on a sunny day! These systems are more complex than they need to be. Long live ICE!!
Change a camshaft in an ICE Mustang then come back and tell me about "complex". Done? Now go change out a bunch of synchros a teenage speed-shifter burned out. Have you ever even changed a clutch? Let me know whenever you are ready to talk about the clutches in 10-speed automatics...
@@Miata822 Billy.. some reason you got your panties all knotted up, maybe you are a dealer oil tech? Was turning wrenches while you were shitting yellow KID! Now go back to watching Speed Racer videos with your dog. lol
From what I've seen I your videos I really got to appreciate how tesla kept thing simple to mantain and produce, this ford really is a mess in comparison
hello we have problem about battery and we couldn’t handle the problem. How can we contact you is there any phone number or something else that we can contact you??
Not a single change for 2023. Perhaps 2024 will bring significant revisions just as new battery tech and more range. Tesla still has the edge because they find ways to keep the weight down, less parts and the latest battery technology.
Straight Up : I work at Ford and the diagrams and information provided to me are subpar, these videos have been a valuable resource.

Hi Dan, I drive a 2020 Sienna van (Braunability side entry conversion). I like the Sienna because it has the tallest roof and widest opening. I also like the reliability of Toyota products. I do not know if a Toyota trailer hitch will bolt on to a converted van. You may need to get a custom hitch manufactured. Best wishes.
Professor Kelly, does the cooling system for the drive unit and inverter have a thermostat or does the coolant pump cycle on and off to maintain proper operating temperature for these components? Thanks for sharing your knowledge.
No thermostat. The coolant pump is variable speed. Thanks for watching
Great video, thank you
Thank you
Amazing professor... thanks so much for sharing this amazing info 👋😎👋😎
Thank you so much
Amother famtastic video professor! What is the book time on removing the battery? Would you consider this process easier than pulling the cab on a ford truck?
Thank you! I do not know the book time, but it is certainly easier than pulling the cab on a Ford truck.
Here I am, can’t even change tiers on my GT. But this wizard removes the battery like it’s nothing 😅
Lol. Thanks for watching!
I have had three of these cars. When I had issues (on first two cars) we visited five different Ford dealerships that (all) told me that they had NO IDEA how to work on my mach-E.
Great information. 👍
Glad you think so! Thank you
I'm suprzed to see no lock-tight thread type sealant on the threads of the Batt bolts... you see in the automotive industry, on Subaru brake caliper setup they use a lot of the time.
The have a locking head design.
Really appreciate Thank you professor .👍
So nice of you
Hello professor, thank you for all your explanation, but I have a doubt, those brackets are sent to be made or can be purchased in the USA. Thanks
This looks very similar in design concept to the Chevy Bolt battery pack, just a little larger. I assume the Toyota BZ4X and Tesla battery packs are about the same, except Tesla use cylindrical instead of rectangular cells.
Thank you sir
Thank you!
Hello. Nice explication! ✌️ from Portugal!
Glad you liked it! Thank you.
@@WeberAuto of course, problem is, at same time...my english it is not perfect...but i try!
How's the quality of the battery tray? I watched one get ripped out at Munro and the welds were awful.
It looked fine to me. The bottom appears to be thin aluminum. There is an inspection procedure to check for damage that might damage the battery modules. Stay on pavement.
Great sir.
Thank you!
Really interesting tear down. I’ve read that there is a weakness in the battery that prevents more than 5 seconds at full power. Is this something you have identified during the tear down? I’d be interested to hear your view on this issue.
The Mach-E GT has a nominal rating for the fuses of 630A (Rear Motor) and 350A (Front Motor). They are pushing the limits with a current draw of 1050 amps during full acceleration. I suspect the fuse sizes, contactor sizes, and maximum allowed current needed to be better calibrated to avoid overheating the contactors (A possible reason for the five-second power limit). I will be surprised if the junction block with contactors and fuses gets replaced due to the recall for the contactor issue.
Professor . So if the 12V battery is disconnected...The HV system is out of order. Same with the interlock. Some remarks from a former diagnostic technician with 35yrs of experience with MB cars . That green plug disconnector .....use a padlock instead of a simple carabiner.
Second , if disconnecting the minus pole of the battery ...put a plastic cap on the minus pole cause that thick cable has a "memory" and can bent back to its former position . Regards from Belgium .
Hi, Maybe you covered this question in earlier video, but what are you tearing into the battery? Bad cells?
Just for fun! There are no problems
The BECM may be the biggest PITA module known to mankind to replace! Are you sure it is serviceable separately from the high voltage battery?
Hi Frank, yes, it is serviceable seperately.
Don't know if anybody else has asked this question. Would it be possible to put an extended range battery in a 22 select all wheel drive? I see there now available in the 2024 model as an option. If this would be possible what would it entail and what would it cost? Do you think you could use a salvage battery if the battery is not damaged. I've seen a lot of totaled Mach Es available online. Total isn't what you might think some of them have what looks like very minor damage. Nowadays are totaling cars out if the airbags are deployed.
@35:23 the energy capacity rating is in kilowatt-hours, not kilowatts. Prof. Kelly knows this - it's just a slip; my comment is only to correct any confusion by viewers.
Can you do the same for a ford E-Transit?
I would like that, but from what I have seen, it is just the RWD Mach-E powertrain with a Van body on it. Thanks for the suggestion
Most torque to yield bolts in most applications can be used up to 5 times. Now this is never recommended to to but I bet if you read the fine print in the ford service manual it will allow more than a one time use.
Thanks for your feedback!
How many people make it to the third episode?
I wonder how far people go.
It's very rare or never in movies to do a 4th.
Everyone does! lol
Professor, I’m curious what the reasoning is for buying the particular trim of the vehicles you purchase. With the model S you have, I believe it is the highest trim (Performance dual motor). The Mach-E is the GT model. I’m just curious why the college purchase these more expensive models, vs something like the Mach-E4x or the Model S long range. I can understand wanting to get the big battery, dual motor versions, but why the performance models?
Thanks for another great video!
Good question. I learned from purchasing our 2017 Bolt EV without all the options (DC Fast Charge) that limited myself from showing my students all of the latest and essential to understand technology. I will always try to purchase the fully loaded versions of these vehicle for educational purposes.
How do i know wich battery pack my Mach E has, SR or ER ?
Professor, I have a question.
Are these batteries officially serviceable for repairs?
Let's say a cell goes bad and the car tells me to contact a Ford dealership for repair.
Would they change just the bad cell, the entire module or even the whole battery? And what about the contractors or the battery management module?
I'm asking because I frequently hear that battery problems in electric vehicles often requires (officially) a full battery swap. But the inside of a battery is so modular that it seems fairly easy to swap just the faulty component.
Any of the 12 battery modules can be changed, same with the junction block (with contactors) and the BMS. My next video will cover those topics.
Yep, there's a battery balancing procedure that may need to be performed. Unlike the Tesla packs, which are a lot less repairable. The structural battery in the new Tesla model y isn't repairable at all.
@@WeberAuto So then its possible to change any individule cells that may be bad by removing the module & testing each cell. Thats the key to keeping a EV affordable.
@@mikemiller659 Tesla are aiming to make 20 million/yr by 2030. No way to do that with traditional manufacturing and repair perceptions. Drivers in this crisis are lower cost by design and ease of manufacturing. This runs through all modern manufacturing technologies. Tesla have found modules to be redundant given the low rate of pack failures. In the third row interviews musk talked about the Roadster needing modules because of nascent battery technology and from then on it went unchallenged until the Model Y.
@@waynerussell6401 feed me daddy Elon
@30:15 Do those bolts really have 7 mm heads? That's tiny, and obscure.
you are my favorite EV specialist I would like to know what is your opinion on battery pack serviceability of Tesla vs Ford, VW ,Audi,Porsche, Hundai, KIA etc... especially the new 4680 cell form factor I would like you if you can make a video on this topic I think it really important when the cars are going to be older and any replacement of any component could be done even used parts like contactor BMS modules etc. but if the battery is made like Tesla you can't even repurposed batteries for solar or any other EV other than using the complete battery pack are you going to get a VW ID4 ? . the way the top cover is removed compared to the top cover of the new Tesla pack see Munro live it's one of the last video it totally a disaster I don't like it.
Thank you very much. I like the possibility of some type of service work on the battery. Tesla may have a good thing there or not; time will tell.
Sandy Munro and Team has nothing on you, Professor!
Thank you very much
👍👍👍👍
Thank you
Aspects of this surprised me in the level of difficulty. I suppose the only excuse is that we're almost never going to have to do this.
This couldn't be more different from a Tesla battery pack, especially the structural 4680 pack that Munro is dissecting, where everything is glued together with polyurethane. Also the new Model S/X battery, which has none of the open space seen in the Ford's pack.
This is true. Tesla packs are notoriously difficult or even impossible to service. That makes them effectivly disposable. Unfortunate.
Ford by design intent made their pack easy to service. In the event of a single failed cell a pack can be replaced without replacing the whole battery. GM has gone one step further, making the pack BMS reprogrammable so that cells could be replaced with some unknown future chemistry to prolong the life of the vehicle.
Tesla's disposable batteries should be cause for investors and owners to complain. It is little different from Apple's new phones where battery replacement is prohibited by the phone's software.
@@Miata822 amen! On the Tesla battery, if a single 4680 cell goes bad, the entire multi-thousand dollar battery has to be scrapped and replaced. Absolutely no serviceability. Almost every other manufacturer splits the battery into smaller, serviceable modules so that just the failed module can be replaced for a far less expensive and wasteful repair. Tesla forces you to replace the entire thing.
Thanks for your feedback
Yet so many electric vehicle backers think they are going to have quick change battery shops instead of having to charge the batteries. There is nothing quick change about it.

Excellent video. Imagine the problems in service work at the dealer with Mech./Techs. that can't find their ass with both hands on a sunny day!
These systems are more complex than they need to be.
Long live ICE!!
Thank you! There is a need for trained quality techs. That is part of my job to teach them.
Change a camshaft in an ICE Mustang then come back and tell me about "complex".
Done?
Now go change out a bunch of synchros a teenage speed-shifter burned out.
Have you ever even changed a clutch?
Let me know whenever you are ready to talk about the clutches in 10-speed automatics...

From what I've seen I your videos I really got to appreciate how tesla kept thing simple to mantain and produce, this ford really is a mess in comparison
Thanks for watching
"tesla kept thing simple to mantain and produce"
produce maybe, but maintain?
wow he's gone old :)
I may be old, but I make up for it by being SLOW!
hello we have problem about battery and we couldn’t handle the problem. How can we contact you is there any phone number or something else that we can contact you??
Not a single change for 2023. Perhaps 2024 will bring significant revisions just as new battery tech and more range. Tesla still has the edge because they find ways to keep the weight down, less parts and the latest battery technology.
Thanks for watching
