The Golden Submarine was an early twentieth century streamlined race car designed and built in 1917 by Fred Offenhauser and Harry A. Miller for Barney Oldfield.

[1] Oldfield worked with Miller, who developed and built carburetors in Los Angeles, to create a racing machine that would not only be fast and durable, but that would also protect the driver in the event of an accident.

Bob Burman, one of Oldfield's top rivals and closest friends, was killed in a wreck during a race in Corona, California.

[1] The car featured a four-cylinder aluminum alloy engine with 289 cubic inches (4.74 L), 3-5/8" (92.075mm) bore × 7" (177.800mm) stroke, 136 hp (101 kW) @ 2950 revolutions per minute (RPM), a single overhead cam, desmodromic valves, dual intake ports for each cylinder, dual spark plugs and magnetos.

[4] The engine problems were ironed out the following week and on 25 June he defeated arch-rival Ralph DePalma three times on the Milwaukee dirt track.
