Cadillac Converj Concept
Equipped with solar panels on the glass roof, the hybrid-electric Converj showcases GMâ€™s new Voltec electric propulsion technology. The concept car also features emissions-free electric driving. While it doesnâ€™t have the signature Cadillac grill, it does incorporate the iconic shield. The four-passenger vehicle is slated to go into production by the end of 2010.
