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%.
