As the U.S. becomes more dependent on foreign oil, Detroit continues to satisfy the public’s demand for gas-guzzling SUVs, even though manufacturers can produce more fuel-efficient cars. News correspondentLesley Stahl reports this and more on CBS' “60 Minutes” this weekend.

Environmental Defense's John DeCicco, a leading auto expert in the environmental community, will appear in the segment and discuss the opportunities to re-engineer vehicles for higher efficiency, a practical, affordable step that could be taken now to reduce both oil dependence and greenhouse gases.
