Mazda will be displaying five new vehicles for the Tokyo Auto Show, three of which will be hybrids. One of them will be the Senku hybrid car, which is based on Mazda's RX-8. It will feature "flying wing" doors and, more interestingly, it will include solar cells that are embedded in the roof, according to AutoWeek. Apparently, the solar cells will be used to help keep the hybrid batteries charged. The name means "pioneer" in Japanese.
