There is a 1000 hp tesla with 3 motors that all together weights about 450 killograms, this seems to support your idea until you look at how much the batteries weigh...

The batteries are 550 kilograms to start, and are generally considered to not be big enough. So yeah, great they solved the issue that no EV had (EVs always had lighter motors, and very heavy batteries).

Edit: The 1000 hp telsa is 2200 Kg total, so yeah this would cut out 400 ish Kgs (assuming cooling and inverter and all that) from the total, not nothing but not really a game changer ether. Also 1000 Hp engine is stupid and not needed, maybe if it was a 200 Hp version but then also that would be diminishing returns as this motor would be what 4 kgs?

~20% weight reduction for a total vehicle weight isn't small change. Plus batteries will continue to improve as well. Do you just get off on being negative?

Yeah, I'm not sure how they concluded in their edit that 400kg is not a lot to shed.

The gains compound a bit too, 20 percent less weight equals proportionally less battery capacity required to shift the now-lighter vehicle from point A to point B.

So then you can cut the size of the battery while maintaining the same range, and that's where you start to get significant overall weight and cost savings.

Hell just replace the former motor weight with battery and you've almost doubled the range. If China ever mass produces solid state batteries, double it again.
