Taking 40 US tons from 0-60 in 20 secs is going to require motors with a BF armature. Any ME's here that want to take shot at estimating the diameter using common materials of those shafts? I've seen modders twist apart drive shafts and dynos pushed over their limits until they break and it's not pretty. The same can go for regen with a fully loaded truck. Can the motors survive a full lock up if the driver stands on the brakes?
