I would like to see a Utility EV to commute and do errands with the option to add more battery power. I'm over 6' tall and prefer SUV's seating and cargo space. A base battery power of 50 miles then the ability to add more batteries or a hydrogen fuel cell. We could put solar cells on the roof to generate the hydrogen. The Chevy Volt is great ... can't wait for the next generation of utility EV's and hydrogen fuel cells.
