I would recommend anyone who is interested in mild hybrids read EddieB's linked article in its entirety. It's the best recent review I have read although it does include numerous unsupported claims as well. Mild hybrids—a multi-billion euro growth opportunity alongside e-mobility? | Automotive World

Having said that, absolutely nothing presented by the article or by EddieB puts any ADDITIONAL NdPr in any real-world 48V mild "hybrid" ICE vehicles. That's the problem ausheds had, too; he kept talking talking talking about them here whilst refusing to do the research that CJ and I did. You got to have math or logic to present an intelligent investment case.

And the one mild hybrid model ausheds offered here was a Daimler product, which (quite unforgettably) was found to have ZERO REEs in its launch-assist motor.

And the one motor EddieB chose to highlight here today? The Aeristech 20kW is a compressor for fuel cells not a drive motor for milds; would be useful in fuel cell vehicles though FCEV manufacturers will most likely use an integrated compressor and fuel cell. The company's history has been making and controlling bolt-on compressor motors for supercharging internal combustion engines; once the ICE is gone, I suspect Aeristech will quickly follow, though it would be nice if they survive helping FCEVs.

So EddieB has no mild motor to talk about. Doesn't matter how many Milds pundits predict will be produced if they don't add magmetal demand; yet another fact that ausheds nonsensically refused to accept.

Another MAJOR problem for Milds is logic, which strongly suggests that NO 48V mild hybrid will EVER use any NdFeB-enabled PMM as a drive motor. Why not? Unnecessary Cost. The cost of lightweighting far exceeds the value. Same could be said about the downsizing. AND ALSO the efficiency as there is no expensive battery to thrift. Everyone is trying to use less REEs but not mild fake hybrid ICE vehicle manufacturers who don't even have a reason to? Not logical? Not happening.

Ausheds used to love claiming over and over that successive generations of 48V Milds would slowly increase the electric motor and battery and decrease the ICE. While such a path would eventually counter this logic, every redesign is a billion-dollar years-long event. And don't forget that ausheds beloved 48V architecture can only support about 20 horsepower electric motor regardless REEs or not, so not really a long-term vehicle design life. If Mild makers wanted to increase the 48V it would add MUCH more.

Mild hybridization adds about $1000 to ICE vehicle cost and any fuel savings are largely a matter of guesswork and duty cycle. Who is served by mild hybridization then? The Big Auto companies who don't want to change.

Still, I'm super-glad someone finally had the respect and integrity to try defending mild hybrids. Kudos.
