Mission E could be a real monster with the lessons porsche learns in Formula E. One of the biggest ways you can tell tesla isn't a car guy car company is they don't have a Model S race series to beat their cars into the ground. Racing will find your poorly designed parts awfully quick.
Fast 0-60 launches a couple times is impressive, but consistent hot laps on a track is much, much harder. Model S can do a couple hot laps before giving up. I fully expect the Mission E to have a lot less quit in it.
