Colonel Edward H. R. “Ned” Green, his wife Mabel and their dog are pictured on Green’s Star Island estate in Biscayne Bay, off Miami Beach, with his custom 1929 Stearns-Knight M 6-80 cabriolet. The car was specially converted into a gearless gasoline-electric hybrid, allowing Green to drive without shifting gears.
Green, the son of financier Hetty Green, commissioned a small series of custom Stearns-Knight based hybrid cars so he could drive without shifting gears. Long before hybrid vehicles became common, these unusual machines paired a gasoline engine with an electric drive system, creating a fascinating early chapter in alternative automotive engineering.
