Also from your source: > As for Audi, I think that they are intentionally giving up their efficiency in order to protect the battery pack and get a higher char

  That statement makes no sense. Efficiency is a measure of energy required to move the vehicle a certain distance, as in Wh/mi. Range is battery capacity divided by efficiency. You can give up range to protect the battery, by limiting the charging capacity or the discharge depth, but you cannot give up efficiency. There are likely a multitude of factors from motors, to drivetrain, to drag, to gross weight which contribute to Audi’s lower efficiency e-Tron. They have a fairly large battery, although smaller capacity than Tesla’s largest, but only get ~200mi of range out of it. Their efficiency and range is lower than the 2012 Model S. This is one area where Tesla has an indisputable technical lead. You could argue, for example, that Audi sacrifices efficiency to have lower interior noise levels, or that they had a body design with higher drag they weren’t willing to compromise. But drag and weight alone don’t fully account for the large efficiency difference.
