For one example I read Tesla is installing MYLR rear brakes on MYP rears.
2022Q4 call
Andrew Baglino -- Senior Vice President, Powertrain and Energy Engineering
“
I was going to say, we're also -- our fleet is starting to mature, the 3, Y fleet. And we're gathering a lot of data out of that fleet to understand how we can sort of bring some margin that we didn't know we had out of the product. So over the course of 2023, on the powertrain side, we're actually going to go after sort of some materials where we're paying for more performance than we need or we have more content than we need without impacting reliability at all. And that will actually add up to a pretty significant cost reduction on the powertrain side over the course of 2023.
So we're not just sort of relying on supply.”
For brakes, reducing the material cost will apply to production as well as replacement repairs and insurance cost.
