Quote from: LouisJ on Yesterday at 18:49:19I have difficulty with the increase efficiency of drive train of 30%. The current EVs drive trains have efficiency over 85%, closer to 90%. An increase of 30% would mean an efficiency over 100%.
I think they likely meant 30% decrease in inefficiency. So 85% would become 89.5%.

Chinese EV makers have been in a race to introduce the world's fastest electric motors, with BYD's Super e-Platform featuring a 30,000 rpm unit. After speed, the electric motor innovation has now moved to developing in-wheel placement, cutting dramatically on drivetrain components.
