Mahle (Germany) has introduced an induction based EV motor that has no rare earth metals and no magnets. That reduces the cost considerably while maintaining high efficiency. They also introduced a lithium/carbon battery that is said to be able to take on a full charge in 90 seconds. It will be interesting to see what companies start employing this technology.

Mahle's cheap, highly efficient new EV motor uses no magnets
Magnets, typically using rare earth metals like neodymium, are found at the heart of most electric vehicle motors. It's nice to have a permanent source of powerful rare earth magnetism in your rotor, because using powered coils instead means you have to somehow transfer electricity from the battery…
