Well, that’s not how efficiency is measured but I think I know what you mean. The Wh per mile is mostly a function of weight. Aero starts to weigh in around 55mph. On conversions a good estimate is weight divided by 10. My car weighs 3100 lbs with me in it and I got around 300wh/m. Tesla beat this by making the battery a larger percentage of total weight by using aluminum. No one else comes close. I think the Bolt is close to the rule of thumb.

I have heard over the years that the defacto EV efficiency is about 3 miles per kWh, measured at the battery, or 333 Wh per mile. So Tesla has done a great job. I wonder what the Bolt and some other longer range EVs can do.
