Comment on No rare earth metals in the Model SComments−zafka12yIt would be possible to build a more compact motor using NFeB magnets, but the cost outweighs the slight weight/performance gain. It is also my understanding that induction motor that Tesla uses is more efficient at regenerative braking.
