First Look: Tesla Model 3 Drive Unit

- This short clip shows the entire rear subframe complete with drive unit and suspension pulled from a salvage Model 3.
The drive unit itself with inverter and full lubrication sump weighs just under 200lbs/90kg. I have more videos in this series showing more detail on the drive unit, inverter, and motor. Check here: / ingineerix
Let me know in the comments below what kind of videos you'd like to see on Tesla tech. Don't forget to subscribe, as there is a lot of cool stuff coming!
I just completed a road trip from CA to Mt. Rushmore in the Model 3. The motor (and car) performed flawlessly. The motor really is a thing of beauty. Never temperamental, always ready. You can pass multiple vehicles in a blink. I had it up to 120 mph in the Wyoming plains, there was plenty left.
I see where the Tesla design engineers got their idea for the drive system for their automobiles: Subway cars and the French TGV drive units! The Tesla drive units look very much identical to that on electrified propulsion trains! However, scaled down for automobiles--pure genius! Bravo!
Such a simple and elegant design that could produce such an amazing performance. There is no freaking way those super complicated and costly to build internal combustion engines and transmissions can compete with this.
They do compete if you're talking about manufacturing cost. It's a lot cheaper. Cost to run/fuel is another story.
ICE's are dead. I'm amazed how much progress has been made in the last 10 years.
@@zolikoff I think he's talking about the drive unit. The drive unit is far superior in most any way to ICE. The current drawback is obviously the heavy pricey battery, but that will change with time.
Range and charging availability. 300 miles isn't great range and if you live in an apartment a lot of people around the county simply don't have access to a charger and who wants to work all day just to get off and sit at a charging station waiting for your car to charge. On the other side of that, if your buying a $60-$100k tesla than you probably not living in an apartment complex 😂
Wait a minute... removing the whole rear drive assembly involves disconnecting only 3 electrical cables, 2 brake lines, 2 glycol lines, 2 shocks, and 4 bolts? That's amazing! That's fewer connections than my motherboard...
Have been thinking about having mine raised, whether through spacers or custom coilovers. Such a simple design should really keep the labour down!
The whole car looks build with an amazing level of simplicity. If you watch other teardown videos its really interesting how clean and tidy everything is, compared to any other car, be it EV or ICE. Somebody put a real effort into the whole concept.
Just curious, why do you want to raise it?
Winter and bad roads (I live in Iceland). My land is off a (short) bad road in the countryside. But even in town, ice and deep snow have done serious damage to my Insight quite a few times. Low cars aren't good here. I'd also love the possibility to do some "minor offroading" (hence my question about water depth in the other thread). A large chunk of our country is only accessible by these highland roads which are unpaved and generally little more than "some guy drove a bulldozer through here". The major ones are mostly just washboardy and potholed, but the minor ones cross lava fields and stuff like that (I will *not* be subjecting my Model 3 to lava fields! There's no chance the suspension could take that. But being able to do the major roads would be nice). Large rivers are bridged, but streams and standing water are not. So again... clearance.
Best option would be one that lets me change between summer mode (normal height) and winter/offroad mode (elevated). Was thinking that a simple way might be air suspension + larger tires, so you get both the benefit of air suspension raising it and the extra height from the tires. And said tires could be winter/offroad tires, kept on an extra set of rims, for easy swapping. The problem with that approach is that the front control arms stick out over the inner lip of the tires with only a finger's width of clearance. There would have to be some way to mount the rims slightly further out to avoid hitting it. But obviously I wouldn't want "summer mode" to be mounted further out; that'd clearly be an efficiency (aka range / charge rate) hit.
Without changing tire sizes, spacers could give some extra height, but they'd permanently lock lower suspension positions off from me. I've been told that given the slack in the lines, probably the most you could raise a Model 3 through spacers would be about 2". Which means that if you have air suspension too, probably no more than 1". In that case, the "low" setting would be like the "normal" setting, and "normal" would be like "high", with "high" putting you about an inch over that, and "Very high" a touch more. Assuming that Model 3's air suspension will have similar settings to Model S's.
Custom coilovers would at least let me adjust the height. But really, the best would be if I could adjust tire size, either instead of - or in addition to - spacers or coilovers. The more clearance in winter/offroad, the better. If I could go from 45 to 65 on the tire aspect ratio, that would add almost two inches, which - with air suspension as well - would bring it up to +3" at low speeds, a touch less at moderate speeds. Might even be able to get away with higher than 65 on the aspect ratio, so long as I never drop the air suspension to "low" with them on. With 1" spacers that could potentially even bring it up to a max of +4". Serious height! But the spacers would be an extra cost and - again - lock off "low" from me in summer mode.
Hate to make this a male female thing, but I have noticed women in Iceland (Europe) consistently answer very technical stuff that I'd hate to say I rarely hear in the US. Probably because education is not only free, its great too. If I am wrong, I'll be happy about it.
ok, so basically a Tesla Subaru. That would be a cool thing...
It's amazing how a tiny motor like that has the level of performance that can push a 4,000 car 0-60 in 5.1 (I think drag times had it as low as 4.6)
Yeah, DragTimes got 4.5-second 0-60. But Tesla seems to have throttled it back to 5.1 secs in a software update.
AWD version can do 3,3ec with optimized tires!
If only I had the money to get the dual motor performance. My finances only allow for the single motor.
well thats already a very nice and fast car! I would love to have any of them.
That's the beauty of electric motors; small, simple and full torque immediately!
This is the most advanced electric motor in the world and Tesla's ace in the hole!
Actually nearly everything about Teslas is very advanced.
Because you would know if it's advanced or not.
what is in there that isnt at least 100 years in use? come back when it runs on fairydust...
+majstealth The permanent magnet activated reluctance motor is possibly the first time in mass production, and it's a major advance since it's highly efficient. Silicon Carbide power transistors have probably never been used in EVs before, etc. Also more efficient. Those are two major examples, among others.
Loanword Eggcorn
Batteries and electronics YES. I don't know about the drive unit. Manufacturing methods and structural design of the cars are not even up to minimal industry standards in terms of build efficiency, weight minimization, etc. (I'm using Munro for as my primary source of information here)
I think I need this for my Honda
Great video man. I cant believe how much smaller the motor is compared to a Model S or X. It almost looks like the one Tesla had in the electric Smart cars for a few years.
Didnt expect it to be so simple. Amazing
I'm impressed that little plate stack can cool the motor. I knew the motors are fairly high efficiency and don't have a ton of thermal loss, but wow that's still something.
These plate-stack type heat exchangers have a LOT of surface area, so with fast moving oil/coolant it can handle a lot of heat transfer.
@@Ingineerix I guess I'm used to our data center style plate stack Heat exchangers. We don't usually have very fast-moving fluid so maybe that's the difference.
Amazing to think that all this is held on by just four bolts! The forces those fouur bolts have to withstand at full acceleration must be insane.
Well if you think it an old muscle car drive train is only held in by 4 bolts also. 2 front motor mount bolts and 2 transmission crossmember bolts.
They are BIG bolts!
Like @Watch said. Not to mention electrical motors deliver strong but very smooth power. Unlike high power ICE cars you need to do the dump the clutch at high rpm thing to deliver the power violently or the car just would not go.
BlackTalon53 Probably should refrain from any Dukes of Hazard stunts with those cars.
The whole Space Shuttle stack was held up by eight bolts - four in each SRB.
engineering marvel
Is it? How so?
such a great compact design.
Excellent bit of kit for an Ariel atom style car,weld chassis around it and place batteries for weight distribution
Wow I’ll be replacing that today on a salvaged Tesla hopefully it’s straight forward
Now let's build one of these to bolt up to an F150....
one? make it 2 and there you go: 4sec 0-60mph. That will be a nice F150
Four, one at each wheel. The it's true 4WD without all the mechanical torque shifting/locking differential complexities.
Pretty sure the Tesla pickup will have basically the same drivetrain from the new roadster. 2 M3 rear motors and 1 M3 front motor. All of them will of course be geared lower. This will give incredible control over traction, and also dynamic stability while towing. Should be pretty amazing...
haha i am damn sure those will NOT be on the pickup. The pickup will have the same as the Truck. The ones from the roadster will be way too expensive for such a car
You do know that the Roadster and Semi both use M3 motors, right? I would expect the Tesla Pickup will be very expensive too btw. 65k+
Absolutely fabulous piece of engineering. I recently had a new E class as a hire car the big manufactures have so far to catch up in design. I know their quality is better most of the time :) the gap is closing though. I always said my next car will be petrol then electric, it will be electric now.
This looks like it is really simple to work on
I would LOVE one day to fit this into the back side of my VW
I think it would be great.
Teslas are definitely game changers!
This thing is so hot! Simple, powerful, beautiful..
Apparently simple , for simple minds. The complexity is shifted in the control hardware and software management unit.
@@MrShimizoo beats having to disconnect a zillion cables and lines to work on the car
A manufacturer should make or sell something for conversions or Self builds. That would be the ultimate environmentally friendly car, one you can rebuild and upgrade forever.
Great info and tremendous work you put in... Could you do some camera training to reduce our dizziness. ie don't constantly rove and wobble the camera from one part to the next. ta :)
hi, i'm having problem with tesla car, now the screen shows errors like :rear motor disabled,unable drive,park assist disabled, do you know where the problem is, help me.!
I am assuming "Front" is the end with the orange power cables?
Can you show us what captures the coil springs on the top?
And could you put a shock in place so we can see its mounting point and orientation?
It is interesting to note the use of welded fabricated steel sections for the sub frame vs the aluminium on the Model S.
Thank you for posting this!
Love these videos. What are you going to do with this line of work? Become an independent service company on Teslas?
What's wrong with the "CZcamsr" line of work?
How can four bolts hold this huge powerful motor?
It's a pretty small motor (200lbs), and the bolts are definitely up the task of the dynamic forces.
Airliner jet engines are held on at 3 attachment points connected with one pin each. Good engineering design is the key.
The front 2 bolts has 128nm and the back ones has 168nm I use to torque these bad boys till I got laid off😒
I want to see how tuners of the future will modify EVs. Everything looks very clean and simple on this car!
Two of these under and early wrx, oh man
Model 3 rear track is 62.2”, GD WRX rear is 50.3”. So 2.9” narrower total, or 1.5” per side. (GC is narrower still.) You’ll need fender flares or different wheels. Subaru used 5x100 wheels for Imprezas but gradually went to 5x114.3. Same as the Model 3. However, Model 3 uses 14mm studs instead of 12mm studs, and “medium offset” of 35mm or 40mm instead of Subaru’s “high offset” of 45mm to 55mm. Then there’s the hub bore: 56.1mm for Subaru, 64.1mm for Tesla Model 3.
The bigger deal would be mounting it. Luckily, we already know the spare tire well in the trunk can be cut out. Subaru also used a saddlebag gas tank that can be removed. Stock rear trailing links could be ditched too. The. You either need to weld parts of the Subaru rear subframe to the Tesla subframe, make adapter brackets, or modify the Subaru chassis to accept the Tesla subframe. Another handy plus are the two access panels Subaru used for access to the top of the gas tank.
Using the Tesla rear springs would be a puzzle, but some air suspension “bag over” kits don’t use them. Instead, the damper attachment points do all the work. Luckily, the GD has some very high rear strut mounts that are very sturdy.
I’d like to know if I could have permission to use a short clip from your video where you show the wheels, drivetrain, and motor for one of my videos. I’ll be talking about how there are less drivetrain losses in Tesla vehicles and I can think of no better way to show this to the audience than what you captured here. Very good video! They are really fun to watch and learn about the car.
Sure, just give credit with a link to my video in your description.
Awesome, thanks so much!
I don’t think Tesla gets enough credit for how workable and interchangeable the parts on the model 3 really is. By modern standards, thing is like working on a 3 cylinder geo metro
Way less moving parts! Engineering is not even in the same world!
Question: Tesla motors are, supposedly, capable of getting up to 18,000 RPM. But this assumes work being distributed to both tires. What if the motor had to spin only one tire? How fast, in terms of RPM, could it get up to then?
Wow so much instead of such a small package very impressive!
En los carros de Metro los motores están dentro de la rueda
Hello, can I put the ludicrous Tesla motor drive unit in a Hummer H1 ?
Can you please create video ( animated can be useful ) how this whole things works ? With explanations for each of the terms like inverter, sub-train, drive-train, coolers etc Thanks in advance :)
found this channel through Electrek
The suspension seems like odd geometry to me. Is that common practice? I guess it's to have the spring off center for the drive axle but I think I would prefer a symmetric design and maybe use two coilovers if necessary. Also I don't care for the concept of a sway bar, particularly not with a low CoG like M3
Could you put a measuring tape on and see what the approximate sizes are?
Love the videos, but the nearly constant panning is almost giving me motion sickness. A few fixed camera positions and a laser pointer would be a lot better camera technique.
I can agree to this!!
Where do I buy my Tesla crate motor?
Exactly what I'm thinking watching this.
Aaron Thorpe get the small block v8. Much more powerful.
@@jmatt98 I don't think anyone's cross-shopping Tesla motors and V8s. If you want an electric motor, no old-fashioned dinosaur juice burner will suffice.
What happened to both tires?
Needs a Corvair attached to it.
thank you for sharing!!
Как же классно спроектирован, прям наслаждение для инженера внутри меня

Would this be water proof if not covered?just thinking of using it for a kit car
I get to make these for a living woohoo
How much does the whole thing weight?
How fast in the dual motor Tesla 3 ?
Those are gonna be great for EV conversions once they are hacked!
I agree. They will be every where soon.
It's already hacked! More to come soon!
Fantastic!
David Seiko how much?
except that they are super exensive still
If you ever played with hobby grade Radio control cars then your pretty much set. The only difference other then size is the ESC (Electronic Speed Control) on RC cars are far more advance in technology the motors come sensored or sensor-less and the ESC are user friendly and easy to tune. I'm surprised no one has attempted to replicate it for a full size EV. It would make life so much easier.
Sorry, I don't know of any hobby ESC's using SicFETs, and definitely none are near the total efficiency of Tesla's. Running a sensorless feedback system in a large traction application is very difficult, and has all kinds of issues.
How wide is it from wheel mounting surface to wheel mounting surface? disc to disc?
Semakin canggih tesla . Bisakah tesla ke indonesia.
How much does all of this weigh without the tires and will a transmission lift hold it?
Motor is 200lbs, so probably 350lbs for the whole thing.
How easy would this unit be to retro-fit into a vintage VW camper.Brilliantly simple.
Seems pretty simple compared to an engine.
I wonder for the battery pack and all other electronics.
I heard that all the electronics communicate and need correct id to function.
Pretty damn good video
Where can I buy this drive unite
Wow. Amazing.
how much
Does anyone know which power of PM SRM motor for this EV?
On a RWD Model 3, Rated max net power is 202kW/271HP and has a max torque of 416Nm/307ftLb.
How wide are these things hub to hub
What’s the price on something like this
Hi, what was the build date of this Model 3? Thanks!
Does anyone know the spacing between the outer subframe mounts please. I can't fine this info anywhere, not even on any of the few rear teardown videos.
I am from India, mountain ghat is very much in my country, I do not understand how much weight an electric car can climb on the ghat, tell me its information
What is the measurement from outside wheel hub to outside wheel hub? I want to use one of these in a EV swap!
Did you ever find the answer to this question? I'm looking for the same :)
is ths narrower than the Model S unit? I want to put some of these in a Cadillac or Caprice landyacht in the future. But I do not want that flush wheels...I want a deep rim-lip, so I need a narrower unit to begin with.
Yes, quite a bit narrower.
how much does an installation of this system cost to another car?
nice..
any idea about the shaft diameter?
some tesla model has 2 motor: synrm(rear) and pm(front)
I want to put one of these in my 1963 Nova SS . I am in. Anaheim California
What made you pull it out?
I'm pretty sure it came out of a totaled Model 3. You can see the ripped inside sidewall of the tire at 1:27. Also at the 1:00 minute mark you can see the inside rim of the wheel is slightly beat up which would never happen to a newly delivered vehicle.
are you planning to sell any of the suspension parts?
So why are they so expensive?
Looks to be realistic to swap into a Fiero/MR2 or any RWD car.
An AW11 MR2 with one of these would be awesome :)
I don't see how Tesla would lose money selling drives and other parts. GM does this with their crate engines. If Tesla waits too long, some other company (say, in China) will make "crate motor bolt-ins". There is a replacement for displacement.
@@RaglansElectricBaboon and deadly....if you could get the tires to even hook up lmao
SW20 rear track is about 5 inches narrower than the Model 3. Both use 5x114.3 wheels with similar offsets, but 14mm wheel studs to handle the Tesla’s torque instead of 12mm on the Toyota.
The good news is that the MR2’s rear suspension subframe is held on with about four bolts. The bad news is that those four bolts are in entirely different locations than the Tesla. Worse news is that the bottom of the firewall between the engine bay and the trunk might need major surgery. Good news is some of that’s been done before by a guy who put a rotary piston engine in an MR2 for 24 hours of Lemons.
Alternatively, you could just mount everything behind the car and create a very long wheelbase MR2. Think outside the box, lol! That would leave the entire engine bay and trunk for batteries.
The MR2 doesn’t require (conventional) power steering, so that’s easy. You’d still need to figure out vacuum for the brake booster..
A stock Mk2 MR2 weighs about a thousand pounds less than a RWD Model 3. Whatever the final weight would be, it would certainly be a cool conversion.
@@Edgar-Friendly Tesla is making more money selling Model 3s than they would selling retrofit kits. Every drivetrain they sell as a kit is a Model 3 they didn't sell. But if the chip shortage means that Tesla could build and sell these drivetrains while the rest of the Model 3 is bottlenecked, then that might be worth developing such kits. We're not there yet, though.
And honestly, I'd rather part a scrap car to retrofit than buy a kit.
Is the tire at 1:27 blown?
How many total moving parts are in this motor?
Jef b 1
Well 1 and 2 bearings I guess. Then a reduction gear, done.
From a marketwatch article re model a: “The company says its drivetrain has about 17 moving parts compared with about 200 in a conventional internal combustion drivetrain. “
@Kim Neeper Rasmussen; and a differential.
Jef b idk but model s's have 97 moving parts
Quando o ser humano parar de ser egoísta, daí em diante pode ser que teremos uma tecnologia dessa a disposição de todos, o fim do combustível focio na verdade já está atrasado, mas infelizmente rende muito pra poucos, e a maioria é quem paga.
good simple
Hey, I have been working on a maintenance manual project for my company. Can I have your permission to use some snapshots of this video? Thanks

How much ?
Width?
how many kw is the motor?
It was rated 204kW, but Tesla recently added some power with a software upgrade, and I don't know what the official rating is now up to.
@@Ingineerix thank you!!
To all you Tesla naysayers, just rent one for week and you will understand completely.
All the things you no longer need worry about mount up quickly. Once realized, there's no going back to ICE.
You're completely right. It takes just one test drive to convince, indeed.
@@0xbenedikt I'm a touch over two years into owning a 3LR and driving has never been so enjoyable. I gotta admit, I'm a bit guilty of feeling superior to other car owners. They just don't know.......
Don't have FSD and never will and just don't use AP. I find the constant reminder by AP an annoyance I can give without.
Surprise, I'm eighty and still enjoy driving my own car.
its looks so simple... modern ice drivetrains give me look overwhelmingly complicated to me.
Do you have any contact info? Had some questions. Thanks.
Send that to the body shop along with the batt packs and I’ll build you a custom hot rod all the other bells and whistles I can do without
And it drops out...? wow
how does it rotates the wheel ?
Magnets.
unit avant ou arriere????
Arriere.
Could you get it to work with just the battery and drive unit, without all the other stuff?
The minimum needed would be the shifter (SCCM), Pack, and Drive unit. You would have to generate some CAN signals with a separate controller.
Ingineerix thanks, I think I could get that to work. I think this would be great.
Contact me when you have a project rolling. I will probably have a CAN controller available by then. These Model 3 components are going into another secret project soon!
I will, it wont be quick, I like the concept of using the Tesla system, Model S, 3 or X but can't do this quickly. Have been looking at damaged cars via ridesafely.com. getting more in state so shipping isn't crazy. Have you ever heard of MAGNAX, they make axil Flux High speed motors.
How much is a good cost for this setup? Also the best spot to get it. Good video ty!
The best bet is to buy a whole wrecked Model 3, as you'll find you need harnesses and all kinds of extra little parts. I do have a controller that can allow full operation of the drive unit outside of the car. Can use the original Tesla pack or any other high-voltage (250-400v) power source. All it requires is the matching (from the same car) security controller (VCSec), Accelerator pedal assembly, and some custom wiring. Once you are up and running you can then sell off all the parts you didn't use and make most of the purchase back.
@@Ingineerix I did find a full setup for a battery for $5,000 of a Chevy Volt batteries setup. Tesla S motor for $11,500. The motor comes from EV West. If you want to see whats all included. Is this a good option? The car I was to use is a Subaru impreza 1998 2.5RS. That is so much for the help. I've never built a car but reading more about electric cars. Its becoming a passion of mine.
The EV West guys are great, and will take care of you, but on all the Tesla drive units they sell, they remove Tesla's inverter drive board (and thus all Tesla's software) and install a third-party board from Europe. This is throwing away a lot of Tesla's awesome engineering for efficiency, power, and longevity. If it blows up, then what? (And they do!) I offer an external controller that doesn't require any modification to Tesla's drive unit, it keeps it 100% Tesla and makes it work as engineered by Tesla. (All protection features are still active) If for some reason there are any problems it's all standard, so replacement is easy and quick. Also, be sure you can fit a Model S drive unit in your Subi, They are large! Personally, I would recommend a Model 3 drive unit, it's much smaller, lighter, and more efficient.
@@Ingineerix You personally sell Tesla 3's? What I'm basically looking for is something that's good performance but also a daily driver. Good performance I mean something that compares to a Golf R or other fast hatches.
No I don't, sorry.
PM or SyRM?
