Ford unveiled plans at the CES show in Law Vegas a solar concept car that offers the same performance as a plug-in hybrid. The C-MAX Solar Energi Concept vehicle still uses a gasoline engine, revealed on Friday, Jan. 10.

However, the car uses a gizmo that acts like a magnifying glass to concentrate the sun’s rays on the vehicle’s roof-mounted solar panels. The automaker says the vehicle’s estimated combined city-highway mileage is 100 mpg.
