Remember, the Prius Prime has a 25 mile AER, so this effectively doubles the electric only range of a Prius Prime. The other big difference is this car is engineered to allow the solar electric to recharge the batteries while driving.


Will this help BEV owners - possibly. Who it will help are the PHEV owners where the limited EV range can cause them to dip into their gas tanks, especially in the winter when that 20% range hit all EVs take comes into play.
That would really be something if they can pull it off but I'm pretty skeptical about the 27 miles (or is it 35 miles the article isn't clear). I wonder if they are extrapolating peak power production, like if you were driving in the tropics at noon on one of the two days of the year when the sun is directly overhead. And requiring that you drive at 1,000 mph so that you could follow underneath the sun
