Which Chicago company produced the early Dual Power hybrid car?

The Woods Motor Vehicle Company of Chicago produced the early Dual Power hybrid car.

Woods was an American manufacturer of electric automobiles headquartered in Chicago, Illinois. The company had built battery-powered vehicles since the late 1890s, but changing customer expectations and competition from gasoline cars encouraged it to combine electric and internal-combustion power.

In 1915, Woods introduced the Dual Power. It used the company’s electric drive system together with a four-cylinder gasoline engine, making it an early hybrid vehicle. Production continued into 1918, although the car arrived during a period when gasoline automobiles were becoming more practical and widely available.

The Dual Power is sometimes confused with products from other early electric-car makers such as Baker, Detroit Electric, or Columbia. Those companies were important participants in the early electric-vehicle market, but the Chicago-built Dual Power was specifically a Woods Motor Vehicle Company product.
