Regarding alternative suspension - raise the vehicle for easier ingress and exit for older people! I'm 75+ - and getting in and out of the Tesla 3 - or most modern small vehicles - is my biggest problem... Martin Bronsdon, Gothenburg, Sweden
Exactly my thought when he said that. My grandmother is 92 and her issue is cars being too low that she has to fall into and has trouble getting out of.
I dont' get it. Tesla already DID make it higher when going from Model 3 (Sedan shape) to Model Y (SUV shape). Sandy Munro showed that with the 13 cm seat risers. In addition, there are 28 mm (1.1 inches) more ground clearance when comparing Model 3 and Model Y, which brings the difference of seat height over ground to about 15,8 cm. I thought, that was the whole point in making/buying SUV instead of sedans: Raising the seats for people getting in and out easier. @Martin, Curtis: Isn't that enough? @Sandy Munro: I never heard of kneeling necessary or beneficial for a compact SUV. But instead either for less aerodynamic drag, which results in more range. Or raising the vehicle to suit different kinds of rough road. Or for auto-leveling the car with heavy payload.
Actually from what I've observed with my mother, a lot of elderly people benefit from a higher seat (not too high) for easier exits, especially. Bottom line: an adjustable air suspension that you could preset as you would the mirror adjustment and the steering wheel height, would be a great option. Then if you have the "need for speed" as all we Tesla owners do, you could lower the suspension when you set out for the nearest freeway entrance. Win - win.
Just wanted to say a big thank-you for the series. I am learning a truckload (pun intended) about electric cars and production. This is really interesting stuff! Thank you very much for doing this.
It's amazing that something the size of a paint can can produce so much power. I have a rear wheel drive Model 3 so it only has the one motor. It is a quick car too!
The superiority of electric motors was never ever in doubt. Size, weight, power, reliability, versatility, economics... Heck, back in the late XIX century they would have never developed and adopted ICE for cars if they would have had any remotely good storage mean to power electric motors.
@@rogerstarkey5390 But a difference is that any size IC car engine can output all it's power when connected to a tiny bottle of gas. It doesn't need a 1,000+ lbs battery.

Love the comparison videos. I'd also love if Sandy were able to just speak on design concepts like adding lightness, as the Lotus guys would say, and interesting or clever ways manufacturers have accomplished that in the past, why it's unique for electrics, etc.
Me too! I've learned so much about what it takes to make a vehicle, it really is so complicated due to all the systems, makes you wonder how anyone can startup a car company.
@@MrCarGuy yes, I understood that, otherwise he wouldn't be explaining some of the terminology that engineers, at least automotive engineers, would be very familiar with.
All these “red dot” differences you note between the model 3 and Y beg the question ... does the Y really share 75% of its parts with the 3 ... or have these changes been incorporated into the 3 since your tear down of that model?
Great question. I am wondering the same. It's impossible to tell what is going into a Model 3 today compared to a Model 3 a year ago. How would any of us know? Maybe the folks at the Tesla dealership will do a teardown before we buy. : )
Great content, exposing the nuts and bolts of the historical evolution of transportation. Would love to see a comparison between all parts used in an ICE engine and transmission compare to Model Y's motor and drivetrain. Displayed side-by-side starting small, with all bolts, nuts and screws to final large pieces, trany cases, etc. And ask the questions: Margin?, Dependability?, Performance? Sustainability?
I love these videos! It's a unique opportunity to get a deeper look not only at a product which nobody else would delve into to such an extent, but also at the automotive industry itself and its giants such as Munro. Fantastic! On another matter: Since they officially say that the Y shares 75% of components with the 3, I'd love to know which, if any, of these many differences between the Y and the early 3 have been already integrated in the newer 3s... How to find out though?
Sandy internet is full of rumors regarding air suspensions. A month ago on Electrek the 12V scheme of MY leaked, calling a TAS (Tesla Air Suspension). Love to see your videos.
@@DavidHRyall air suspensions are good idea but for oofroading not really , because it gets used quickly and considering the weight of the cybertruck....
Model 3 and Y both have schematics for air suspension. The bodies and components are capable of going to air setup, always have been. If you know where to look you can find a place for air tank and compressor, firmware too if your really good. Cost is preventing offering the option. Don't know everything involved, above my pay grade.
Hi, thank for the video. Would like to see a more detailed video about stator cooling of the Tesla (Oil cooling flow or Glycol ?) and also a review of the complete Audi E-tron electric motor, especially on the rotor and stator cooling side. (Rotor cooling rotating sealing method ?).
The S and X use Bilstein hydropneumatic struts similar to those in Benz, Audis, Bentley etc. They are prone to premature wear, interestingly not in care hire vehicles running 24/7, but rather in ones that are used infrequently suggesting that the system, which remains pressurised even when the car is parked, prefers movement. I have a Y on order. I don't want the Bilsteins. They cost $6,000 to replace.
Yes, so I hope Tesla will make "basic" lo maintenance pneumatic shock absorbers that simply raise /lower / adjust height also depending on total weight.
For that price point, it would be pretty nice to have electronic controlled shock absorbers if not the full fledged air suspensions... At least as an option, i mean, every other "premium car" Tesla always compares their sales to has that optional extra.
@luca Mino, well if those other cars had the smoothness, the near zero maintenance, the lifetime longevity of the power train if the Tesla.. but they don't. So I think you are already getting a better car for the same money. That said I AM waiting for the air suspension option to get my model Y. I'll pay for it as an option. 😃
@@JohnFields the suspension feature is independent from the propulsion system, as is stuff like double layered glass windows. Is something to be expected at a certain price range. Especially cause the electronic adjustable dampers are very easy to put in (just swap the regular ones out and a couple of wires) and are pretty cheap compared to a full fledged air suspension, but still offer customizable ride and a much better experience than standard coils. That said, I'm the first one to recon the advantages of electric cars.
@@luca7069 all true, but not equivalent.. double layer glass adds cost. Non market standard suspension parts add cost. Fine Corinthian leather, adds cost. My point was "in the price range" competitors don't have EV advantages at ANY cost, so be careful of treating them as equivalent dollar for dollar.
@@JohnFields i get what you're saying, but i mean, electronic dampers are offered by other brands as an optional extra sometimes for even less than a grand. Plus, i wouldn't mind if Tesla added them but as an optional extra. Active suspension pack for improved ride? Even 2000 dollars would be a not to unreasonable price. Not much production line change for that matter, they're identical to standard ones pretty much.
You know, because those motor laminates have 6-sided star cutouts, they could be made into clock faces with the addition of an off-the-shelf clock movement and a custom-cut backer board material. I bet Tesla motor laminate clocks would be a popular merch item for y'all to sell.
@@nycandre True, that - though their low-volume high end cars are interesting, too. All four models are evolving, and not just marketer-driven shell changes to mark new model years like the competition.
@@markplott4820 Can't use 'Model S' for Semi, the name is taken. Probably can't use Model A, Ford owns that one. I think now that S3XY is completed, Tesla is moving to different naming conventions. Semi is Semi, Cybertruck is Cybertruck, Roadster is Roadster. They don't have a budget model yet to bother with naming it.
@@KimCJorgensen but the end plate has that little tooth(not sure of the correct term) that slides in to slot made in the thread, this would prevent it from rotating.
Hi o/, Why not use a permanent magnet motor at front as well? Because of cost? Or maybe energy regeneration? What would be the advantage of induction motor?
Yes, induction is much simpler and cheaper: the windings induce all the fields instead of permanent magnets (rare earth!) being always 'on' and producing a field. So during acceleration the induction motor can get you there at a lot lower build cost and only slightly higher energy needed. But for example, at deceleration the perm mag motor rules as it makes all the regen for free. With induction motor your have to actively power the fields, is:energize the coils, to have a field that the rotor can pass through to create regen. Interesting fact: you can use more power energizing an induction motor than you recover from realized regen. It will still give you a braking force though, sooo.. it is a set of calculated design tradeoffs between cost/availability vs. peak efficiencies. Make Sense?
This might help with the technical differences, but not really the cost difference: chargedevs.com/features/regenerative-braking-a-closer-look-at-the-methods-and-limits-of-regen/
Both 3 and Y have capability for air suspension (wiring, firmware, mounting points, etc). Just no plan as of yet to offer the option. Production processes like the sticker and the need to differentiate within MOS have been in place for a awhile.
Sandy, have you ever seen rubber insulators or bushings between the upper strut mount and the car's body? is that a thing? reason for asking is the harshness of the Model 3 (and I assume also Model Y) on broken roads where sharp but short impacts transfer to the body with little dissipation. Or is it supposed to be absorbed by a bushing between the strut and the mount?
Lighter is better is not always true, namely when it comes to crash safety. The passengers on heavier vehicles have much better chance getting less injured because they decelerate slower in a collision. It's better for handling, for fuel consumption and for brake distances but for collisions you really want to be in the heaviest vehicle possible. Love your show! subbed.
@@Stefan_Dahn haha, not really, I drive an Audi A8 4.2 TDI from 2006 ( "only" 1850kg ) but I am drooling for an electric from Tesla. They are on another league when it comes to electric cars and the hardware/ software side of things.
Talking as a complete amateur I understand that one of the motors would be a switched reluctance motor (SRM) and the other an induction motor. There is not a permanent magnet motor being used at all, the SRM design has a reputation for high efficiency but cogging at low revs has been cured by the tesla design team. A permanent magnet motor is quite different in design and needs a large number of usually expensive Neodymium magnets, whereas the SRM motor uses some magnets to help smooth the cogging. I accept that I may have misunderstood and bow to your superior knowledge on the subject
A question for Sandy - Normally a motor that drives out of both ends has one solid shaft. Could one stator drive two shorter rotors with a support bearing between them? I’m thinking a split shaft putting power out of both ends won’t need a differential. It would need two reduction boxes but if these were epicyclic the costs would come down and durability goes up. (Straight cut gears load shared across two pinions not three).
Planertary gears are "quite" complex and naturally coaxial. I guess the two stage spur gears also move the center of the end shaft closer to the bottom of the car. So the drive shafts can be shorter and the "angle of attack" is smaller.
Great question! That black bolt-on component that you see on the rear caliper is an electric motor that controls the electronic park brake (EPB). This execution is called "MGU on caliper", as the electric motor is mounted such that it uses the piston in the caliper to apply the park brake vs. an old-school drum-in-hat brake with a cable-pull mechanism. Many newer cars are moving toward this execution. Thanks for tuning in!
So, on the cast frame, how much force is exerted on the location boss for the spring mounts, it looks like the amount of material is insufficient to take a beating.
There is a thin web vertically above the boss and a fairly thin 1/4 inch flange, but I would have thought that the stress applied to this area would create a point of stress failure, constant flexing will lead to failure
looks like the whole rear end assembly can drop down removing a few bolts. That's got to make servicing easier than on a conventional car (once you have the right equipment to catch it of course).
I don't see your point. And it's definitely NOT just a few bolts, but in addition: 1) at least two coolant lines, with a need to collect the leaking fluid and refill and vent the cooling system afterwards 2) two brake pipes, with a need to collect the leaking fluid and refilling and bleeding the hydraulic braking system afterwards 3) at least two strong high voltage DC wires from the battery to the rear drive unit, with a need to deactivate the high voltage system beforehand (plus all safety measures) and reactivate afterwards 4) unplugging a few electrical connectors to the control unit of the rear drive unit and rear wheel speed sensors 5) with a pneumatic rear suspension coming: two more air pipes or electric wires for electromagnetic suspension Munro only makes it seem so easy to take everything apart. They simply do not show the messy and tedious tasks. But instead, I guess, Sandy comes to work and mechanics have already prepared the stuff for his analyses. Like a surgeon getting most patients prepared by assistant doctors. And most "conventional cars" have front wheel drive, so the rear axle is way simpler. The exhaust and fuel tank might interfere however, depending on the construction.
Sandy does the build indicate a possible retrofit suspension as being offered by Tesla? As a current Y owner the rigid suspension is one of my primary complaints (LR model) it’s more stiff than a previous Audi S5, as a crossover I was hoping for a more forgiving setup. I hope Tesla offers some type of suspension upgrade down the road for those of us who prefer a a less kidney jarring experience.
Can you confirm the way the EDM is made of. We can see it is a Permanent Magnet Synchronous machine with some step skew in the middle. We can read a lot of fake info about this motor being revolutionary and hybrid PM synchro reluctant motor. One of my colleague read somewhere it may have magnets on the outside parts and be different in the middle part, possibly without magnets as a variable reluctance machine. Could you confirm or deny this from the M3 or MY motor teardown ?
Maybe some of the differences can be explained because this is model Y Performance, I don't think the model 3 they analyzed was performance...or was it?
Musk hasn't been afraid to try non-standard tech. I've been waiting for someone to bring back Citroen's hydraulic suspension using the electronic and hydraulic controls available today. The advantage over air suspensions is the incompressible fluid allows a more immediate response to valve settings while potentially delivering a buttery smooth ride. Ride height varies, of course, just like an air suspension.
All standard suspension systems are hydraulic in one way or another. Citroen had a hydropneumatic suspension using nitrogen gas. The system was and is superior. Citroen also used electronic controls for an active suspension in the 90's.
@@mcplutt Exactly. That's why I think it is time to revisit. Modern electronic controls are miles ahead of where they were in the '60s. Citroen used an engine driven hydraulic pump to adjust fluid levels but separate electrically driven pumps for front and rear makes a lot of sense. That and modern hose construction would drastically reduce leakage problems as well. Wouldn't be cheap, probably more suited to a high end S or X.
@@mcplutt well ya I agree that is the basis but in an electric motor, it is one in the same. The more efficiently you convert electrical energy into mechanical energy the more power AND efficiency you get. So, still seems odd for them to be so different. I was also wondering if one was much heavier than the other, weight distribution going on maybe.
Suspension and wheels would be the easy parts. The hard parts would be: protecting the battery from being punctured, the glass roof, welding a roll cage around high voltage electronics, it being so damn heavy, and recharging between rally stages. Plus, if you bang up the corners or rocker panels on a normal rally car it isn’t a huge deal. Damage a rocker panel on a Model Y and see how much that costs.
I guess this would result in to big stress on the suspension arm. But what you could get maybe alternativly to the - possible - airride are distance plates for some additional ground clearance like Mountain Pass Performance from Canada is offering for the Model 3 nowadays.
Yeah, I tried to leave a tip on the counter for my casheir. He wouldnt take it, had no tip cup. He said he couldnt take it, so.. I lathered up in some hand sanitizer, took my money back. I proceeded to stick out my hand to see if he would shake it, and take the money in my hand. Hey, that worked! Not so great experience thought, I did probaly cost him his job shaking hands, living maine. Gosh im lucky I wasnt shot when i stuck my hand out. If your gonna tip, your gonna have to be creative.
I just became a Patron, and that gives me access to "secret" information, according to my friend the weed dealer. I have it on good authority that it is expected that in total, derived by using core math skills and statistical analysis of variable constants, there will be all of them.
That's definitely not out of the range of possibility. We've torn down vehicles from the APAC, LATAM, and EMEA markets before, so if the demand is there and it makes business sense for us, we'd absolutely consider it. Thanks for tuning in!
things I didn't know about Tesla cars, would fill a lot of books. But happy to add to that today, I didn't know 'they' had separate coils and struts. I like the idea of magnetic suspension, OK got to add that too. It's absolutely fascinating to see this much detail from an EV, dare say it would be as interesting to see a ice stripped, but ev's, are maybe more relevant. Thanks Munro Live excellent work
Sandy, I am getting s little older and perhaps more importantly fatter, I would probably want to raise the height for ingress and egress rather than lower it. Just an observation.
Might we see an ability to customize the parked height based on individual's preferences? Might be a phone app one could use to set up the car for the driver who is approaching. Height, seats, temperature, radio station, etc. I'm on the older side and not tall. I'd probably set up so that the car seat was about as far off the ground as my favorite chair at home. I neither have to climb into it, as I do with my high clearance pickup, or lower myself down into it as I would with the two seater sports cars I no longer drive.
Sandy, thanks again for sharing your expertise. Could someone comment on how air suspension compares with conventional coil suspension, or McPherson struts, when it comes to maintenance costs?
I wonder why Elon keeps denying air suspension is coming to the 3 or Y if they’re going to do it eventually. I don’t care about air springs on either Model 3 or Y. I just want adaptive dampers to improve ride quality over rough roads when cruising, while allowing firm damping for high speed sporty driving. I only think air suspension is really worthy of use in vehicles like the Land Rover Discovery/Range Rover/Range Rover Sport, etc. My Land Rover needs the air suspension when going off road to allow extra ground clearance, while it’s also able to lower itself a couple of inches to make ingress/egress easier. It also lowers itself an inch or so at highway speeds for better efficiency. On the Model 3 and Y you aren’t going to be taking these vehicles off road. They’re not designed for it. They’re also low enough already that getting in and out wouldn’t be helped by lowering the vehicle further. Adaptive dampers would solve the biggest problem with Model 3 - ride quality - while being much less problematic to fix, lighter weight and more people would likely option that since it would likely cost substantially less money than an air suspension option.
Seems like the much of this vehicle is coming from outside of the box. Pretty obvious Tesla is moving at speeds we've never seen in the automotive industry. Truly amazing, and thanks Sandy, for the recognition of our heroic and underpaid front line workers, risking their lives so we can pick up food and drink.
They're putting their health on the line (being exposed to a lot of people at work) for the benefit of the public. And not being much recognized for it.
So would Sandy not recommend they Model Y for the moment? If air or magnetic suspension is better than maybe we should wait. I bet the Cybertruck and the Roadster will have air or magnetic suspension.
Interesting to see whats inside the Tesla. For this price range the suspension components must be aluminum not cheep stamped sheet metal. Air suspension comes with its benefits and penalties...air compressor for example and another electric motor to turn it, air acumulators , valves and regulators= another 50 punds and additional power consumption for support systems. I dont see it as a huge benefit at this type of a vehicle. As far as the electric motor, again nothing special there, just great engineering. Very sucsessful commercial format, Ilon will be happy with you...
@@cadman10000 Mmmmm....nnnnn...well model Y has a bit more ambition than Honda Civic for instance...and for all the benefits and more of the aluminum alloy suspension components a simple google search would provide plenty of info...or ask Ilon
@@MrSvetlin09it's not "sheet metal." It's high strength steel. The parts that need to be cast aluminum are, the ones that don't aren't. Your assesment of air suspension is laughable. You're not as smart as you think you are.
@@MrSvetlin09 not bitter at all. I've Been working in auto industry for years and I know that you know nothing about the subject matter at hand. Its obvious to anyone with any automotive experience. Otherwise, expound upon your claims. Show us what an expert you are.
Magnetic suspension in cases in copper tube the inadiniam magnets how it slows way down as it goes through copper tube what happens if you have a ball of magnetic and other one that is different pallerity then it would be a suspension that is smooth like riding on air you could a just from waight so add coil on top to adjust so more exspensive but could use for space x crush legs so wouldn't have to replace the legs with aluman can style like moon lander ajusts and bounces back when no weight on it and smooth landing on asfault or even the moon with this design
What I've been trying to find out for a year is a straight answer about equipment on the disparate trom levels. You, for example, are dissecting a Performance Y and Tesla keeps absolutely mum about the differences between say, the Performance model's motors and the Standard or LR models. I1 Tesla took off the cover under his Performance and noted the parts # on his motor was different than on a LR model, but they looked exactly the same. Web searches find info all over the place. The invertor on the Performance model is larger but eyeballs say the motors are indentical. Some suspect the hardware is exactly the same in the motors and that it is just software and invertor you pay so much more for in the Performance. Tesla offers a Stealth Performance Model off menu. Same car programming without Track Mode, 18" wheels and no upgraded brakes. We want to know because the Performance costs so much more than the other models and does 0-60 mph over 1 second faster.
An old response to this question circa 2 years ago was that both motors are exactly the same, but Performance motors are the ones that bench test better than average ones and are pulled aside for the P models. I prompted this question to a Tesla mobile tech ("Tesla Ranger" ) and he said Performance models get larger wires and bigger invertor. Who knows the truth of the Tesla Performance secret?
Magnetic suspension could recuperate the travel energy back to the battery (doesn't Audi offer this?), detect bumps (and have the software map them so the car can avoid/adjust suspension when travellling over the same road again for a smoother ride)
I'm betting on magnetic suspension. Elon is big on magnets. They may be a bit more pricey, but they save in service/maintenance because there are no touching parts. People are willing to pay $$$ if they are guaranteed never to have to come in for repairs (I know I would, and it's one of the reasons I bought a Model 3 - because I was so tired of endless trips to the garage for service maintenance and repairs)...when we think about the robotaxi scheme it makes even more sense. They certainly want their own fleet of cars to be as maintenance free as possible.
The front motor has better regeneration capability, the back motor has better efficiency. Its good because when braking its better to brake with the front wheels, and acceleration is better with the rear wheels.
Tesla seems to move to an electromagnetic suspension like the Bose Suspension ua-cam.com/video/kJ0ljaqeZ1g/v-deo.html or Audi Active Suspension ua-cam.com/video/P7QQLxthHyQ/v-deo.html

I am not an engineer, but I find these videos fascinating.
Me too! I've learned so much about what it takes to make a vehicle, it really is so complicated due to all the systems, makes you wonder how anyone can startup a car company.
He made them specifically for non-engineers.
@@MrCarGuy yes, I understood that, otherwise he wouldn't be explaining some of the terminology that engineers, at least automotive engineers, would be very familiar with.
Glad I went back for the double take! Wondering if there's still hope for air suspension in 3 and Y!
These videos are so much fun to watch! Keep it up!
All these “red dot” differences you note between the model 3 and Y beg the question ... does the Y really share 75% of its parts with the 3 ... or have these changes been incorporated into the 3 since your tear down of that model?
If you count each cell as a part....
Great question. I am wondering the same. It's impossible to tell what is going into a Model 3 today compared to a Model 3 a year ago. How would any of us know? Maybe the folks at the Tesla dealership will do a teardown before we buy. : )
@@davidhunternyc1 why would they tear down one of their own products when people like Sandy will buy them and tear them down?
@@JamesLarson47 It was a joke. So we can see if the car we are buying has the new updated parts or last years specs.
@@davidhunternyc1 Ah, my mistake. I wasn't able to identify it as a joke.
Love the way sandy says " A couple of cute little things "
Thanks for the very informative and fun videos, a great contribution in this strange times! Please keep up with it, great job!
Gave five bucks to the grocery checker... on your suggestion.
He appreciated it.
Thanks for the idea!
Hope you washed the $5 bill. :)
MUNRO ON DEMAND...HOW MUCH FUN ! on a sleepless night.
I’m watching those ads end to end hope it helps lol
Thanks for the support, Nicholas!
Thank you Munro team! Can't wait to hear your final thoughts on MY vs M3. Cheers.
Great content, exposing the nuts and bolts of the historical evolution of transportation. Would love to see a comparison between all parts used in an ICE engine and transmission compare to Model Y's motor and drivetrain. Displayed side-by-side starting small, with all bolts, nuts and screws to final large pieces, trany cases, etc. And ask the questions: Margin?, Dependability?, Performance? Sustainability?
There is Weber Auto youtube channel where they tear down a Chevy Bolt and a lot of ICE cars. There is about 6 hours of detailed info on the Bolt EV.
I love these videos!
It's a unique opportunity to get a deeper look not only at a product which nobody else would delve into to such an extent, but also at the automotive industry itself and its giants such as Munro. Fantastic!
On another matter: Since they officially say that the Y shares 75% of components with the 3, I'd love to know which, if any, of these many differences between the Y and the early 3 have been already integrated in the newer 3s... How to find out though?
Sandy internet is full of rumors regarding air suspensions. A month ago on Electrek the 12V scheme of MY leaked, calling a TAS (Tesla Air Suspension). Love to see your videos.
Vito Di Lascio I think they are just creating components that will be used in the Cybertruck, getting ahead of the curve now so the ramp is quicker
@@DavidHRyall air suspensions are good idea but for oofroading not really , because it gets used quickly and considering the weight of the cybertruck....
Model 3 and Y both have schematics for air suspension. The bodies and components are capable of going to air setup, always have been. If you know where to look you can find a place for air tank and compressor, firmware too if your really good. Cost is preventing offering the option. Don't know everything involved, above my pay grade.
Your theme music is banging. Takes me back to when I binge watched GoT.
Sandy, what is the purpose of the bearing lock nut? Is it to hold compression on the laminates?
Considering the internal stresses and the large gauge of the threading.. I would bet yes even though they are glued in place at end of assembly?
Any ETA on heat pump analysis?
Yea, I'm wondering about what refrigerant the utilises.
Hi, thank for the video. Would like to see a more detailed video about stator cooling of the Tesla (Oil cooling flow or Glycol ?) and also a review of the complete Audi E-tron electric motor, especially on the rotor and stator cooling side. (Rotor cooling rotating sealing method ?).
The S and X use Bilstein hydropneumatic struts similar to those in Benz, Audis, Bentley etc. They are prone to premature wear, interestingly not in care hire vehicles running 24/7, but rather in ones that are used infrequently suggesting that the system, which remains pressurised even when the car is parked, prefers movement. I have a Y on order. I don't want the Bilsteins. They cost $6,000 to replace.
Yes, so I hope Tesla will make "basic" lo maintenance pneumatic shock absorbers that simply raise /lower / adjust height also depending on total weight.
The level of content and expertise that we are getting for free is crazy... please support the Patreon
I have been wondering about the Red Dots! Thanks!
For that price point, it would be pretty nice to have electronic controlled shock absorbers if not the full fledged air suspensions...
At least as an option, i mean, every other "premium car" Tesla always compares their sales to has that optional extra.
I think every other "premium car" in it's segment should have a long range electric option...
@luca Mino, well if those other cars had the smoothness, the near zero maintenance, the lifetime longevity of the power train if the Tesla.. but they don't. So I think you are already getting a better car for the same money. That said I AM waiting for the air suspension option to get my model Y. I'll pay for it as an option. 😃
@@JohnFields the suspension feature is independent from the propulsion system, as is stuff like double layered glass windows. Is something to be expected at a certain price range. Especially cause the electronic adjustable dampers are very easy to put in (just swap the regular ones out and a couple of wires) and are pretty cheap compared to a full fledged air suspension, but still offer customizable ride and a much better experience than standard coils.
That said, I'm the first one to recon the advantages of electric cars.
@@luca7069 all true, but not equivalent.. double layer glass adds cost. Non market standard suspension parts add cost. Fine Corinthian leather, adds cost. My point was "in the price range" competitors don't have EV advantages at ANY cost, so be careful of treating them as equivalent dollar for dollar.
@@JohnFields i get what you're saying, but i mean, electronic dampers are offered by other brands as an optional extra sometimes for even less than a grand.
Plus, i wouldn't mind if Tesla added them but as an optional extra. Active suspension pack for improved ride? Even 2000 dollars would be a not to unreasonable price. Not much production line change for that matter, they're identical to standard ones pretty much.
You know, because those motor laminates have 6-sided star cutouts, they could be made into clock faces with the addition of an off-the-shelf clock movement and a custom-cut backer board material. I bet Tesla motor laminate clocks would be a popular merch item for y'all to sell.
those individual laminates would make for a nice ornament , maybe concider selling a few of those
Could you please measure the inductance in both inductors? The front one has the same diameter, but seems shorter. Thanks.
In, YOU have a great day, Sandy!
Look at their 4th mass market vehicle, Tesla is still evolving in car design. Amazing
Really SECOND mass market car - Model 3 was the first truly mass market car from Tesla
@@nycandre True, that - though their low-volume high end cars are interesting, too. All four models are evolving, and not just marketer-driven shell changes to mark new model years like the competition.

@@markplott4820 Can't use 'Model S' for Semi, the name is taken. Probably can't use Model A, Ford owns that one.
I think now that S3XY is completed, Tesla is moving to different naming conventions. Semi is Semi, Cybertruck is Cybertruck, Roadster is Roadster. They don't have a budget model yet to bother with naming it.
@@Urgelt - Andrej Kaparthy AI Expert recently Updated the SEXY CARS extinsons.
How is the end plate pressed against the rotor laminates if there is no bearing lock nut?
Looks like the end plate is threaded, i.e. the end plate IS the nut.
@@KimCJorgensen but the end plate has that little tooth(not sure of the correct term) that slides in to slot made in the thread, this would prevent it from rotating.
Hi o/,
Why not use a permanent magnet motor at front as well? Because of cost? Or maybe energy regeneration? What would be the advantage of induction motor?
Yes, induction is much simpler and cheaper: the windings induce all the fields instead of permanent magnets (rare earth!) being always 'on' and producing a field.
So during acceleration the induction motor can get you there at a lot lower build cost and only slightly higher energy needed. But for example, at deceleration the perm mag motor rules as it makes all the regen for free. With induction motor your have to actively power the fields, is:energize the coils, to have a field that the rotor can pass through to create regen. Interesting fact: you can use more power energizing an induction motor than you recover from realized regen. It will still give you a braking force though, sooo.. it is a set of calculated design tradeoffs between cost/availability vs. peak efficiencies. Make Sense?
This might help with the technical differences, but not really the cost difference: chargedevs.com/features/regenerative-braking-a-closer-look-at-the-methods-and-limits-of-regen/
@@JohnFields awesome
Could it be that the same sticker is used for s & x? Therefore it means there won’t be other suspension options for the Y?
Adam A or maybe this is the unit that will also be used in the Cybertruck, which will have air suspension
They are saving cost by using the same sticker for all vehicles!😁
Sticker has QR code that must be scanned, so, no.
Both 3 and Y have capability for air suspension (wiring, firmware, mounting points, etc). Just no plan as of yet to offer the option. Production processes like the sticker and the need to differentiate within MOS have been in place for a awhile.
Sandy, have you ever seen rubber insulators or bushings between the upper strut mount and the car's body? is that a thing? reason for asking is the harshness of the Model 3 (and I assume also Model Y) on broken roads where sharp but short impacts transfer to the body with little dissipation. Or is it supposed to be absorbed by a bushing between the strut and the mount?
Lighter is better is not always true, namely when it comes to crash safety. The passengers on heavier vehicles have much better chance getting less injured because they decelerate slower in a collision. It's better for handling, for fuel consumption and for brake distances but for collisions you really want to be in the heaviest vehicle possible. Love your show! subbed.
Are you a heavy load oversize truck driver then? 😉
@@Stefan_Dahn haha, not really, I drive an Audi A8 4.2 TDI from 2006 ( "only" 1850kg ) but I am drooling for an electric from Tesla. They are on another league when it comes to electric cars and the hardware/ software side of things.
Thank you Sandy again for your work on to show what Tesla can or have to do better.
Dankeschön für das Video.
👍👍👍🇺🇸🚐🇺🇸😷😷😷
#stayathome #staysafe
this is great!!! keep it up!!!
Talking as a complete amateur I understand that one of the motors would be a switched reluctance motor (SRM) and the other an induction motor. There is not a permanent magnet motor being used at all, the SRM design has a reputation for high efficiency but cogging at low revs has been cured by the tesla design team. A permanent magnet motor is quite different in design and needs a large number of usually expensive Neodymium magnets, whereas the SRM motor uses some magnets to help smooth the cogging. I accept that I may have misunderstood and bow to your superior knowledge on the subject
So the laminates are plain steel/iron? Or something exotic? (permalloy, metglass, ?)
A question for Sandy -
Normally a motor that drives out of both ends has one solid shaft. Could one stator drive two shorter rotors with a support bearing between them? I’m thinking a split shaft putting power out of both ends won’t need a differential. It would need two reduction boxes but if these were epicyclic the costs would come down and durability goes up. (Straight cut gears load shared across two pinions not three).
Planertary gears are "quite" complex and naturally coaxial. I guess the two stage spur gears also move the center of the end shaft closer to the bottom of the car. So the drive shafts can be shorter and the "angle of attack" is smaller.
It looks like a work of art and engineering.
What is that other box that’s on the break calipers?
Great question! That black bolt-on component that you see on the rear caliper is an electric motor that controls the electronic park brake (EPB). This execution is called "MGU on caliper", as the electric motor is mounted such that it uses the piston in the caliper to apply the park brake vs. an old-school drum-in-hat brake with a cable-pull mechanism. Many newer cars are moving toward this execution. Thanks for tuning in!
Another great video.
What about the stator temperature sensor? Did you notice that is not there anymore?
Love it. Thank you.
@Sandy " leaving the nut away " ( 8:00 ) = not only less weight but also a lot less production and controle costs .
Sandy, What year M3 are you comparing with MY? I wonder if the parts that are different in your comparison are same in the latest M3.
It doesn't really matter because either way we are seeing the progress Tesla is making
Probably a lot are as he reviewed one of the early M3s
2018
LATE Produced Model 3
@@markplott4820 EARLY
@ 8;00 How do they hold the bearing in place without a locknut?
It does not appear to me it would hold the bearing, but rather clamp the stator core. The bearing is press fit on the shaft.
maybe the 2020 model 3 uses most of these model Y parts as well since the model 3 evolves
Boys and girls ,
Would like to have classes like this at college !
Not ICE engines ...
Check out Weber Auto for a number of classes on the Bolt EV.
So, on the cast frame, how much force is exerted on the location boss for the spring mounts, it looks like the amount of material is insufficient to take a beating.
There is a thin web vertically above the boss and a fairly thin 1/4 inch flange, but I would have thought that the stress applied to this area would create a point of stress failure, constant flexing will lead to failure
looks like the whole rear end assembly can drop down removing a few bolts. That's got to make servicing easier than on a conventional car (once you have the right equipment to catch it of course).
I don't see your point. And it's definitely NOT just a few bolts, but in addition:
1) at least two coolant lines, with a need to collect the leaking fluid and refill and vent the cooling system afterwards
2) two brake pipes, with a need to collect the leaking fluid and refilling and bleeding the hydraulic braking system afterwards
3) at least two strong high voltage DC wires from the battery to the rear drive unit, with a need to deactivate the high voltage system beforehand (plus all safety measures) and reactivate afterwards
4) unplugging a few electrical connectors to the control unit of the rear drive unit and rear wheel speed sensors
5) with a pneumatic rear suspension coming: two more air pipes or electric wires for electromagnetic suspension
Munro only makes it seem so easy to take everything apart. They simply do not show the messy and tedious tasks. But instead, I guess, Sandy comes to work and mechanics have already prepared the stuff for his analyses. Like a surgeon getting most patients prepared by assistant doctors.
And most "conventional cars" have front wheel drive, so the rear axle is way simpler. The exhaust and fuel tank might interfere however, depending on the construction.
@@koeniglicher Good points... it just looked so nice and neat assembled on the floor!
Most all vehicles use subframe assemblies. Nothing novel in that regard.
Sandy does the build indicate a possible retrofit suspension as being offered by Tesla? As a current Y owner the rigid suspension is one of my primary complaints (LR model) it’s more stiff than a previous Audi S5, as a crossover I was hoping for a more forgiving setup.
I hope Tesla offers some type of suspension upgrade down the road for those of us who prefer a a less kidney jarring experience.
what engines did you compared exactly 980 or 990? (m3 vs my)
Waiting for the day they speak only about the mega cast , have literally waited a year for it !!!

7:01 From the movie Alien?
How about create the magnetic 🧲 suspension
Can you confirm the way the EDM is made of. We can see it is a Permanent Magnet Synchronous machine with some step skew in the middle. We can read a lot of fake info about this motor being revolutionary and hybrid PM synchro reluctant motor. One of my colleague read somewhere it may have magnets on the outside parts and be different in the middle part, possibly without magnets as a variable reluctance machine. Could you confirm or deny this from the M3 or MY motor teardown ?
Maybe some of the differences can be explained because this is model Y Performance, I don't think the model 3 they analyzed was performance...or was it?
Musk hasn't been afraid to try non-standard tech. I've been waiting for someone to bring back Citroen's hydraulic suspension using the electronic and hydraulic controls available today. The advantage over air suspensions is the incompressible fluid allows a more immediate response to valve settings while potentially delivering a buttery smooth ride. Ride height varies, of course, just like an air suspension.
All standard suspension systems are hydraulic in one way or another. Citroen had a hydropneumatic suspension using nitrogen gas. The system was and is superior.
Citroen also used electronic controls for an active suspension in the 90's.
@@mcplutt Exactly. That's why I think it is time to revisit. Modern electronic controls are miles ahead of where they were in the '60s. Citroen used an engine driven hydraulic pump to adjust fluid levels but separate electrically driven pumps for front and rear makes a lot of sense. That and modern hose construction would drastically reduce leakage problems as well. Wouldn't be cheap, probably more suited to a high end S or X.
@@Miata822 Citroen had the system on their cheaper models too. The GS in the 70's and the BX in the 80's and 90's.
Why the difference in motors between front and rear?
One is for power, one is for efficiency.
@@mcplutt well ya I agree that is the basis but in an electric motor, it is one in the same. The more efficiently you convert electrical energy into mechanical energy the more power AND efficiency you get. So, still seems odd for them to be so different. I was also wondering if one was much heavier than the other, weight distribution going on maybe.
@@zmass They work best at different speeds too. One for lower speeds and the other for higher speeds.
Do you think the Model Y could be modified to be a rally car? Would need a long travel suspension and bigger wheels.
Suspension and wheels would be the easy parts. The hard parts would be: protecting the battery from being punctured, the glass roof, welding a roll cage around high voltage electronics, it being so damn heavy, and recharging between rally stages. Plus, if you bang up the corners or rocker panels on a normal rally car it isn’t a huge deal. Damage a rocker panel on a Model Y and see how much that costs.
Is there a possible for a company to add portal hubs to increase ride height? Would they work at all?
I guess this would result in to big stress on the suspension arm. But what you could get maybe alternativly to the - possible - airride are distance plates for some additional ground clearance like Mountain Pass Performance from Canada is offering for the Model 3 nowadays.
@ Seth Marksberry
Would be extremely dificult w Tesla and no doubt void the warranty
However Bolinger EV truck has portals check that out
Mr Munro, put them together and tell if model Y can survive 1M mile?
Yeah, I tried to leave a tip on the counter for my casheir. He wouldnt take it, had no tip cup. He said he couldnt take it, so.. I lathered up in some hand sanitizer, took my money back. I proceeded to stick out my hand to see if he would shake it, and take the money in my hand. Hey, that worked! Not so great experience thought, I did probaly cost him his job shaking hands, living maine. Gosh im lucky I wasnt shot when i stuck my hand out. If your gonna tip, your gonna have to be creative.
Quick question: how many of these episodes do you expect to be there in total?
I just became a Patron, and that gives me access to "secret" information, according to my friend the weed dealer. I have it on good authority that it is expected that in total, derived by using core math skills and statistical analysis of variable constants, there will be all of them.

things I didn't know about Tesla cars, would fill a lot of books. But happy to add to that today, I didn't know 'they' had separate coils and struts. I like the idea of magnetic suspension, OK got to add that too.
It's absolutely fascinating to see this much detail from an EV, dare say it would be as interesting to see a ice stripped, but ev's, are maybe more relevant. Thanks Munro Live excellent work
alot of cars on roads already have the best suspensions, from the rolls royce to mercedes maybach to porsche, bugatti.....
Sandy, I am getting s little older and perhaps more importantly fatter, I would probably want to raise the height for ingress and egress rather than lower it. Just an observation.
Might we see an ability to customize the parked height based on individual's preferences? Might be a phone app one could use to set up the car for the driver who is approaching. Height, seats, temperature, radio station, etc.
I'm on the older side and not tall. I'd probably set up so that the car seat was about as far off the ground as my favorite chair at home. I neither have to climb into it, as I do with my high clearance pickup, or lower myself down into it as I would with the two seater sports cars I no longer drive.
Alternativly, you can adjust your personal body weight distribution and save a lot of bucks. 😜
Remember that the Model Y is already taller than the Model 3.
I think people should consider more reliability AND reusability
I would guess that m3 also has these motors now, as that seems to be how Tesla rolls. Rolling updates.
Thank you for your tips
Wow! Very very nice!!
Another fantastic video! :)
Sandy, thanks again for sharing your expertise. Could someone comment on how air suspension compares with conventional coil suspension, or McPherson struts, when it comes to maintenance costs?
Also general info re pros/ cons. Recalling the first air suspensions were the Citroen DS, modeled after the French tanks ...
I wonder why Elon keeps denying air suspension is coming to the 3 or Y if they’re going to do it eventually. I don’t care about air springs on either Model 3 or Y. I just want adaptive dampers to improve ride quality over rough roads when cruising, while allowing firm damping for high speed sporty driving. I only think air suspension is really worthy of use in vehicles like the Land Rover Discovery/Range Rover/Range Rover Sport, etc.
My Land Rover needs the air suspension when going off road to allow extra ground clearance, while it’s also able to lower itself a couple of inches to make ingress/egress easier. It also lowers itself an inch or so at highway speeds for better efficiency. On the Model 3 and Y you aren’t going to be taking these vehicles off road. They’re not designed for it. They’re also low enough already that getting in and out wouldn’t be helped by lowering the vehicle further. Adaptive dampers would solve the biggest problem with Model 3 - ride quality - while being much less problematic to fix, lighter weight and more people would likely option that since it would likely cost substantially less money than an air suspension option.
To prevent Osborning.
Elon gets criticized if something is late so he is better off sandbagging or just quietly putting it into production.
@@archigoel Right on. I thought the same.
Seems like the much of this vehicle is coming from outside of the box. Pretty obvious Tesla is moving at speeds we've never seen in the automotive industry. Truly amazing, and thanks Sandy, for the recognition of our heroic and underpaid front line workers, risking their lives so we can pick up food and drink.
I like helping people as much as the next guy, but what is the deal with the cashiers?
They're putting their health on the line (being exposed to a lot of people at work) for the benefit of the public. And not being much recognized for it.
So would Sandy not recommend they Model Y for the moment? If air or magnetic suspension is better than maybe we should wait. I bet the Cybertruck and the Roadster will have air or magnetic suspension.
Interesting to see whats inside the Tesla. For this price range the suspension components must be aluminum not cheep stamped sheet metal. Air suspension comes with its benefits and penalties...air compressor for example and another electric motor to turn it, air acumulators , valves and regulators= another 50 punds and additional power consumption for support systems. I dont see it as a huge benefit at this type of a vehicle. As far as the electric motor, again nothing special there, just great engineering.
Very sucsessful commercial format, Ilon will be happy with you...
Why must the suspension components be aluminium?
@@cadman10000 Mmmmm....nnnnn...well model Y has a bit more ambition than Honda Civic for instance...and for all the benefits and more of the aluminum alloy suspension components a simple google search would provide plenty of info...or ask Ilon
@@MrSvetlin09it's not "sheet metal." It's high strength steel. The parts that need to be cast aluminum are, the ones that don't aren't. Your assesment of air suspension is laughable. You're not as smart as you think you are.

Magnetic suspension in cases in copper tube the inadiniam magnets how it slows way down as it goes through copper tube what happens if you have a ball of magnetic and other one that is different pallerity then it would be a suspension that is smooth like riding on air you could a just from waight so add coil on top to adjust so more exspensive but could use for space x crush legs so wouldn't have to replace the legs with aluman can style like moon lander ajusts and bounces back when no weight on it and smooth landing on asfault or even the moon with this design
Mexwell worked on some electronic shock absorbers, so maybe something has been developed here
What I've been trying to find out for a year is a straight answer about equipment on the disparate trom levels. You, for example, are dissecting a Performance Y and Tesla keeps absolutely mum about the differences between say, the Performance model's motors and the Standard or LR models.
I1 Tesla took off the cover under his Performance and noted the parts # on his motor was different than on a LR model, but they looked exactly the same. Web searches find info all over the place. The invertor on the Performance model is larger but eyeballs say the motors are indentical.
Some suspect the hardware is exactly the same in the motors and that it is just software and invertor you pay so much more for in the Performance. Tesla offers a Stealth Performance Model off menu. Same car programming without Track Mode, 18" wheels and no upgraded brakes.
We want to know because the Performance costs so much more than the other models and does 0-60 mph over 1 second faster.
An old response to this question circa 2 years ago was that both motors are exactly the same, but Performance motors are the ones that bench test better than average ones and are pulled aside for the P models.
I prompted this question to a Tesla mobile tech ("Tesla Ranger" ) and he said Performance models get larger wires and bigger invertor.
Who knows the truth of the Tesla Performance secret?
Magnetic suspension could recuperate the travel energy back to the battery (doesn't Audi offer this?), detect bumps (and have the software map them so the car can avoid/adjust suspension when travellling over the same road again for a smoother ride)
That would be AWESOME!
Yeah. They already have that. Magneride. Not perfected yet, but it's potential could be much much better than coil suspension in all aspects. 👍
I'm betting on magnetic suspension. Elon is big on magnets. They may be a bit more pricey, but they save in service/maintenance because there are no touching parts. People are willing to pay $$$ if they are guaranteed never to have to come in for repairs (I know I would, and it's one of the reasons I bought a Model 3 - because I was so tired of endless trips to the garage for service maintenance and repairs)...when we think about the robotaxi scheme it makes even more sense. They certainly want their own fleet of cars to be as maintenance free as possible.
Re the TWO different engines, can someone point out their differences, how they balance ea other in the propulsion of the car ?
The front motor has better regeneration capability, the back motor has better efficiency. Its good because when braking its better to brake with the front wheels, and acceleration is better with the rear wheels.
