Yeesh. I get 44 mpg in a much heavier Toyota hybrid. But it probably depends on what percentage of your driving is in the city, vs highway.

You really do have to do the math using your local costs. I'm in a place with slightly cheaper gas but much cheaper electricity than California. Combined with cheap night time electricity I'm paying under $0.03 per mile for a large EV. I would need 150 mpg vehicle (assuming $4.50 gas) to beat that. However I'm cheating a bit - I'm on a plan which raises my day time electric costs a small amount in exchange for half-price at night, so they're getting some of that back, and I should amortize charger and electrician work ($1600 for me).
