Model Y Performance Rear Motor

[Urbancowboy]

Can anyone with a Y performance take a picture of their rear motor and post it here? Stick your phone up behind the drivers side rear wheel and you should be able to get a clean shot of the motor and more importantly the plate that has info on model number.

Given the power output of the Y vs 3, some of us 3 owners would love to know this information.

Thanks in advance!

What number are you looking for?
This?

Yes, 980 specifically. Thank you!

What is in the latest Performance Model 3 rear drive unit?

So....what does that mean?

Brooks with Dragtimes showed PY makes more power that P3. I think he’s looking for hope of further P3 unlocked power if the motors are the same.

Are they the same or what???

Yes 980 is what’s used on all Model 3 performance and on model 3 AWD through early 2019 build dates. After that the rear motor on the AWD switched to a 990. My guess is the AWD Y is a 990.

AWD Y sports the 980 motor as well.

Same. 23xx VIN

What's the difference between the 980 and 990?

 

[BobbyD1]

Also confirming 980 motor on LR AWD. Vin 7XX

 

[ergela]

All AWD and P models are built the same right now (just like early 3 production). Hence the performance VIN (8th digit F) for all cars.

What's the difference between the 980 and 990?

Well that's a great question

There's a huge thread in the 3 forums about it.

Objectively? We don't definitively know.

But in context we can speculate a fair bit.

The 990 only exists in LR AWD (non-P) model 3s, and only since early-mid 2019 (they were all 980s before that- and 980 is what continues to come in everything else 3 (and apparently Y too))


So... why does the 990 exist?

There's 2 axis of consideration here- cost and performance.

We know the 990 isn't higher performance (if it were it'd be in the P, not the AWD).

We know the 990 isn't higher cost (if it were- why would it exist at all?)

Looking at combos of these 2 factors-

We know it's not same cost and same OR lower performance (because again- why would it even exist?)

We know it's not lower cost and SAME performance- because if it were they'd stop using the 980.


The only option left is- Lower cost and lower performance.

Which fits all known facts and data. I've yet to see any other theory that does.

How about efficiency as a differentiating factor between the two motors?

 

[P3dStealth]

So the model 3 could potentially be faster but if they unlocked it we would be getting close to model S performance territory.

I doubt they want that.

Nope.

2020 LR AWD and 2020 LR P (with 18s) are identical efficiency ratings

 

[Jeffgtx]

It could just exist to track a difference between multiple suppliers of a similar component.

 

[P3dStealth]

What's the weight of the model Y?

We could potentially calculate the acceleration increase if the model 3 motor were unlocked to the model y spec.

Nope.

Covered in other thread in some detail- but if they were functionally interchangeable they wouldn't have one of them appear exclusively on a single trim, and they'd both be under a master PN in the catalog for repair/replacement purposes....among the other reasons.


For example PC makers often have 2 or 3 brands of drive that are considered equivalent- there's a master PN that tells manufacturing "Put one of MP123 in this box" and you can drill down under PN MP123 and see 3 different lower-level PNs any one of which counts as MP123-- and whatever brand the factory happens to have a bunch of that week based on supply chain, that's what goes in... so the laptops you get this week might have a Samsung drive, and next week a Toshiba drive, both under the same master PN. If a drive fails under warranty they'll replace it with whatever brand is on hand when they do the repair under the master PN.


Yet 100% of non-LR-AWD 3s get a 980, and (since mid-2019 anyway) 100% of AWD LR 3s get a 990...and nothing in the catalog suggests one can be replaced with the other for a repair.
