http://arstechnica.com/cars/2016/05/battery-bump-for-bmw-i3-existing-owners-will-be-offered-upgrade-too/ I like the idea of being able to retrofit a car to add more battery capacity. The BMW i3 looks like a nice city car but I am glad to have a FFH. I'd rather drive a FFH for the ride, comfort, and looks. It's an exciting time to live and see how electric vehicles are evolving. I can only imagine the range and prices of EV's in 5 years or so!
