"A new magnet technology invented at the U.S. Department of Energy’s (DOE) Argonne National Laboratory could help drive the nation’s transition from gas-powered vehicles to electric and hybrid power more rapidly, at lower cost and in a more environmentally friendly way."

"the gain in the magnet’s usable flux density ranges from 10 to 30 percent, depending on the application and working temperatures, said HyMag’s inventors, Argonne’s Kaizhong Gao and Yuepeng Zhang."

This HyMag tech can be used to either get more power from the same battery or less loss (allowing a smaller battery).

This is great basic science R&D here. Wish we as a country were supporting more of it.

That will drive down the cost of wind power even more with it already the cheapest at less than 4 cents a Kwh. (or any generation for that matter).

I could use a list of which cars use permanent magnet or electromagnet for the motor . Tesla being one.

and

http://www.thedrive.com/tech/17505/...ir-motors-its-not-all-about-the-battery-folks

lists Other manufacturers of electric vehicles that use permanent magnets include BMW BMWG, Nissan and Geely
Tesla has traditionally used induction motors up to the Model 3. The Model 3 has a reluctance motor in the rear with some added PMs on the stator for better NVH. Dual motor TM3s have an induction motor up front. Pretty much everyone else uses PM motors.
