I'm not reading anyone's marketing material. If you want to dispute the shipping weight, feel free to correct this website whom I assume charges for shipping based on weight [0]. I'm sure they'd love to know they have it wrong.
According to purchasable equipment, the Model 3 engines weight ~175 lbs. If that's wrong, that's on them for claiming it. Subtract 28 lbs from that and you're at 147 lbs. That is very close to 150 lbs.

That’s a drive unit, which is more than the motor. Read the description:
> This kit includes the Tesla motor, inverter, gear box, power cables and drive shafts.
Drive shafts, gearbox, power cables, inverter. Also includes the mounts, which is likely not factored into the lab calculations for this marketing material.
You cannot drop 150lbs from the Model 3 motor because it doesn’t even weigh 150lbs.
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

Smaller motor can be one per wheel which means a shorter drive shaft, less rotating weight which means more torque to the road under acceleration and deceleration.
Tesla still doing a gearbox? Their marketing has been telling me they got rid of those. Typical.
