" I have a friend who spoke with EV engineers at several top companies and they all think – after having done teardowns – that the Tesla motor design is junk, completely incapable of long life under the rapid acceleration that Musk likes to promote so heavily." -- Whitney Tilson, Business Insider

Any top EV engineers out there care to speak for themselves?
Here's your chance!
Now lets scrutinize that bold statement a bit
EV engineer - what sort of engineer is that? Is that electrical engineer working in EV industry? Or is it mechatronic engineer? Or mechanical engineer? I could go on and on, but this is the first time I heard a term EV engineer.
What exact engineering discipline is the said EV engineering referring to and how does one qualify to become EV engineer?
My thinking is that only someone not familiar with the existing engineering disciplines would use a term EV engineer as it is not precise, correct or meaningful.
Hey, not even mighty google has an answer to what an EV engineer is. There is not a single google return to a search on ev engineer. Not a single definition. The reason there is no definition of the term is because the term was coined by someone who has no understanding of what they talk about.
Of course, I can be wrong and will gladly accept correction if it comes my way. Anyone wishes to clarify what exactly is EV engineer?
Next step in the statement: EV engineers at several top companies - I am so curious which top companies employ these unclarified mysterious EV engineers.
Lets move further into so far ignorant and meaningless statement.
The teardown of Tesla motor reveals that the motor design is junk?
Gimmeabreak
The proof is in the pudding. How many motor failures were there in Tesla cars so far? I have not heard of a single motor failure in Tesla cars. If someone offers the evidence to the contrary, I will stand corrected and mightily surprised.
AC motors are vulnerable to overheating and ball bearing failures. Tesla manages the heating issues extremely well with a liquid cooling system and controlling monitors. Motors should last the life of the car.
Conflating motor reliability with drive unit reliability (or noise, to be precise) just shows speakers lack of understanding of what they talk about.
