So, in the magnet-less design, are they saying that you are more efficient because your motor won't pull away energy/speed when not powered? As opposed to a permanent-magnet design, where you have to constantly add energy to maintain speed? That's one quick explanation for how a magnet-less design would be more efficient... After driving an EV for a while now, coasting is the number one thing that drives me crazy when driving an ICE car. It just isn't something that my mind thinks about anymore, so when it happens, it's a bit jarring at first. My wife's profile in my car is set to "coast" mode because she is the opposite. Her primary car is an ICE, so when she is driving my EV, it is jarring for her too! I guess, for me, this would really have an impact on highway driving. And with non-highway driving (changing speeds frequently), I'd rather have the better one-pedal control. But what I didn't see what how much of an impact this would really have for energy efficiency. Maybe the end game here is a magnet-less design that has a longer highway range. So you'll have two different range numbers: city vs highway ranges. Which would be very similar to the city vs highway MPG ratings we currently have for ICE cars. But those are the numbers I'd really like to see.
