That's the big drawback to range and ease of conversion, they are working on an easily made axle/wheel setup that can be dropped into just about any car, with either 4-2-1 motors.
When you take out the standard drive chain/axle setup you save a couple of hundred kilos, which makes a massive difference to range and amount of batteries you can carry. Once they work that all out, conversions for urban vehicles should come in at around $5000-$10000. Rural long range they are looking at less than $20000, for a range of over 500klms and 4x4.
Using 4 motors, you don't need axles or diffs, each motor operates like a LSD, which sounds great, but if the electronics carks it, you may just go round in circles, or not be able to turn. So fail safe systems have to be developed and those are the hold ups for conversions at the moment.
Ahh makes sense, most available conversions are just connected to the gearbox , which I find very uneconomical when I looked into it. I see there are companies still trying to get in wheel motors working, lots of engineering needed to stop inertia though.
Please if they get a web site set up id be very interested to have a look...
You know the worse thing is the old 161 motor is almost 70 years old and still gets 10 litres for 100km, just shows how little they bothered to improve modern motors in efficiency...
So what's the exact problem with in wheel motors?
