Both of those are hard. A big powerful sedan is the best case for electric. You get the big power for free, and you don't end up that heavier or more expensive than a powerful gasoline drivetrain. Small low power cars and trucks that need to be able to tow are the worst case. Giving up the big power doesn't really save you any mass or cost, and trucks need a bigger gas "tank". But perhaps if the tabless and structural battery thing works out, it will get us to both of those cases.
