A little more research turns up the actual cost. "There is additional value added in design and equipment improvements such as the now-standard integrated solar roof panel, which would have been a $5000 option"
It 'theoretically' can add 4 to 5 miles per week in range, but in actuality, the power generated is mostly used to cool the inside of the car when it's parked out in the sun, so there is little actual battery power gain over a car which doesn't have a solar roof, but is kept out of the sun
Certainly a good looking option (what could look neater on a battery powered car than a roof made up completely of solar panels?) and no doubt functional (after a lunch stop it would be nice to come back to a car which isn't so hot inside) but for $5,000 one has to wonder if the cost is anywhere near worth the benefit? Even if Mitsu could somehow manage to pull off a solar roof for half the $5K cost, I think the extra $2500 would detract from car sales . . . . especially once people saw how little return they were getting for all that money - It would have to be an option, for sure
