American Harry Miller completed the Golden Submarine, a new kind of car with a metal roll cage inside the driver’s compartment, for renowned US racer Barney Oldfield. Aerodynamically advanced and wind-tunnel tested, the streamlined racer was years ahead of its time. The $35,000 car featured a 4.74-litre, single overhead cam, cross-flow, water-cooled, 136-horsepower, 4-cylinder engine, which would make it the forerunner of Miller’s highly successful Offenhauser racing engine of later years.
