Woods Motor Vehicle Company was an American manufacturer of electric automobiles in Chicago, Illinois, between 1899[2] and 1916.
In 1915 they produced the Dual Power (U.S. Patent # 1244045) with both electric and internal combustion engines which continued until 1918.
The company was started by Clinton Edgar Woods who literally "wrote the first book on electric vehicles.
Twin electric motors, situated at the rear of the car, produced 2.5 hp (1.9 kW) each.
The Woods Dual Power had a drive-train based on Roland Fend's U.S. patent number 1,303,870, using a clutch between the gas engine and the electric motor, allowing the engine to also drive the car through the armature shaft of the motor, which itself was connected to the driveshaft.
