I'm hoping the great Professor John D. Kelley of Weber State University (see his WeberAuto videos on YouTube) will get ahold of a MINI Cooper SE. Without someone like him, people like me (someone who has exchanged car engines, changed internal engine parts, etc.) are left pondering a big blob of inscrutable mechanisms (and losing motor-cover grommets due to removing the motor cover too often to look at what's underneath):
Thanks! I'd pay that in a second if Munroe did the same for the MINI Cooper SE. I may still pay that in a few minutes after wondering what it says about the i3's motor and drivetrain (sadly, by far the smallest of his PDF files). However, the best would be watching Professor Kelley spinning the actual parts as he assembles them on his bench while he spouts gear ratios, bearing sizes, support structures, design tricks, etc.
Thanks! I enjoyed reading about the electric-motor technologies BMW considered and found the diagrams and graphs very informative (OK, I didn't understand all the graphs, but they look cool).
