Is it also true the new Prius runs on solar power as well?

You got the story a little twisted; it is true the new Toyota Prius will offer an optional glass moonroof packaged with solar panels, but these solar panels are used to power a ventilation system that prevents the vehicle temperature from rising while in park. That way when you get in your car you don't have to crank the air conditioning to maximum, effectively killing any efficiencies gained using a hybrid powertrain. And before you bow down to the Prius, keep in mind the Mazda 929 was doing this back in 1992.
