You're missing the forest for the trees. Dropping 10 lbs per motor is HUGE. Dropping 30 is amazing. Whatever is dropped, it's significant. Pretend that it isn't all you want, but anyone doing production work knows how important this is.
I'm happy to compare apples to apples when we can do that, and if you want me to say I was wrong about the Tesla motor size I'm happy to say that I was just going by what was available on the internet and skipped the details. But I did so in service of a point which you still haven't actually engaged with beyond "Nu uh!".
> Dropping 10 lbs per motor is HUGE.
Auto makers could drop 10lbs, 100lbs or even more from every EV right now by choosing more expensive materials, more expensive manufacturing processes, or simply cutting back on amenities.
10lbs is not significant in the grand scheme of things. The real question is how much it costs, what are the tradeoffs, and how practical is it.

That’s not a fair take on what I’ve been posting at all. I said every little bit helps, but pointed out that motor sizes are already small.l
10 lbs per motor in an aircraft is huge. And the fact that they can do it WITHOUT having to use more expensive materials or manufacturing or amenities is the thing that is huge about it.
It's a fair take on your responses because talking about a SINGLE motor is missing the point. You're not engaging with the actual point that OP made, you're trying to dispute OP by engaging in your own point about what difference this would make in single-motor cars, instead of what difference it will make in general.
> 10 lbs per motor in an aircraft is huge.
That's cool but the conversation was about cars. It's a welcome but tiny improvement for cars. Even after you multiply by 2 or 4, especially because the more motors a car has the smaller they are.

The Boeing 737-800 is the best selling jet liner in history with over 15,000 manufactured.
The 737-800 has a maximum takeoff weight: 174,200 pounds (79,010 kilograms).
What’s 10lbs got to do with anything?
