Camaro Outruns Mustang

Ford Motor Co.'s Mustang is falling farther behind the Chevrolet Camaro as the top-selling U.S. sports car, jeopardizing a Michigan factory as designers work to win back the hearts of pony car fans. Ford narrowly lost the crown in 2010 after a 24-year run, and the gap widened this year, with General Motors Co.'s revived Camaro outselling Mustang by 33 percent through May.
