EV motors are not that heavy. Ok it is 1/4 of a tesla motor but would that make much of a difference compared to the rest of the car since the weight of an EV motor is in single % of the entire weight. Sounds like it could be more important for drones?

Saving up even few % of weight while not compromising on comfort/safety is a holy grail for any decent car manufacturer.

Not sure why the negatives in this thread (maybe too many folks hold TSLA stock?), this is properly awesome (r)evolution.

Outperformance metric is basically power density. The model described is some 13 kg and delivers 750 kW peak, 350+ kW sustained. (That's 28 pounds, 1000 hp peak, 470+ hp sustained.) The 40% improvement is actually 36% and is versus the previous model of the same company.

> That's 28 pounds

or about the same as a small dog

Yet Another Sale Abroad. Not a criticism of the YASA team. It’s hard to scale a company in the UK and foreign investment is a good thing in general. But still frustrating that the UK was unable to offer the kind of investment that Mercedes could to keep a company British.

We're a country who even sold our water to the highest international bidder ...

What would make you think we wouldn't sell our tech crown jewels also? (throwing in our grandparents and children to sweeten the deal).

The new YASA axial flux motor weighs just 28 pounds, or about the same as a small dog. But how many footballs a small dog weighs?

Which kind of football: the British or the US-American one? :-)

Earlier quoted context omitted.

But EVs are already heavy because of the battery. I suppose percentage-wise the motors don't make much of a difference (?)

The issue with this type of motor is that it is part of the unsprung weight since it is inside the wheel. This is probably why savings here matter a lot more (or at least in a very different way) than the battery weight.

See also the Saab Emily GT project. Even with an older, heavier gen of these axial flux motors they found significant performance gains by controlling each wheel via its own motor.
