My 2014 BMW i3 was built that way--CRFP body panels made the car weigh half that of similarly sized vehicles.? Unfortunately, its somewhat quirky appearance limited its US sales (but Europe is crawling with them).? Also, by the end of its run, its EPA range estimate had quadrupled with advances in battery tech.? Unfortunately, BMW didn't offer battery upgrades, (there is a guy in the Czech Republic who does) so while I intend to keep the car forever, its first gen batteries currently limit its use to strictly erranding.? Also, not a big deal, but a warning for all in-vehicle technology, BMW ceased support of its driver app because the cell phone companies abandoned 3G tech) so there are no more nav or software updates.? In ten years of ownership, its only maintenance items have been new tires (3x).? At ~150k miles, its batteries are 85% of new.
