The Curved Dash Oldsmobile is credited as the first high-volume mass-produced automobile. The runabout could seat 2 passengers, and sold for $650.00, the lowest price point on the market. The flat-mounted water-cooled single-cylinder engine, situated at the center of the car, produced 4hp, relying on a brass gravity-feed carburetor. The transmission was a semi-automatic design with two forward speeds and one reverse. The low speed forward and reverse gear system are a planetary type (epicyclic). The car weighed 850 lb. and used Concord springs.
