It seems Hyundai has had enough of Toyota stealing the hybrid spotlight, so the South Korean carmaker is gearing up to do a little Prius hunting. The Blue-Will Concept sports a 1.6-liter engine and a 100-kilowatt electric motor, which is powered by a lithium-ion battery pack. Another neat trick is that the panoramic roof “integrates dye-sensitized solar cells which can generate power for the batteries from the sun without impeding visibility,” according to Hyundai.
