|Headquarters||Springfield, Massachusetts, United States|
The Knox Automobile Company was established in 1900 and built 15 cars their first year.
The 1904 Knox was a runabout model. The angle iron-framed car weighed 1850 lb (839 kg) and used side springs. It could seat 2 passengers.
3 or 4 wheels
Back seat driver
In some models, passengers rode up front over the front axle while the driver and another passenger sat in the back over the engine.
The "Old Porcupine" engine
The flat-mounted single-cylinder engine was air-cooled. Rather than flanges to improve the efficiency of cooling, 1,750 threaded 3/16 inch (5mm) diameter rods were screwed into the cylinder casing as projecting studs, which led to the engine sometimes being referred to as "Old Porcupine". A 2-speed planetary transmission was fitted. This engine was situated at the center of the car and produced 8 hp (6 kW). It was also called a "hedgehog".
The "Knoxmobile" sold for US$1350. By contrast, the Ford Model F was US$2000, the FAL US$1750, the Cole 30 US$1500 and Colt Runabout each US$1500, the Oakland 40, US$1600, and the Enger 40 US$2000, while the high-volume Oldsmobile Runabout ran US$650, Western's Gale Model A US$500 and the Brush Runabout was US$485.
