The Dodge 30 was an automobile built by the Dodge Brothers in Detroit. It was an evolution of the first model, the 30-35. It was introduced in July 1916.
Like its predecessor, the car had a side-valve four-cylinder engine with a capcity of 3479cc. The engine gave an output of 35bhp (25.7 kW). This displacement corresponding to 30 taxable horsepower, which explains the name Dodge 30.
Power was driven through a multi-plate dry clutch (instead of a cone clutch like its predecessor) and a three-speed transmission (with floor shift) to derliver power to the rear wheels. The rear wheels were mechanically braked. The wheelbase of the chassis was lengthened from 2794 mm to 2896 mm. For four-door and two-door touring roadster, there was "Rex" versions, with plug-in windows of the Rex Manufacturing Co. There was also a two-door sedan and a two-door coupe.
In 1918, the model was built without major changes, the already standard electric lighting was fitted along with an electric starter and a tachometer as standard equipment. In 1919 more bodies were added, such as a four-door sedan and a taxi with six seats.
1920 accounted for the "Rex" versions and the windshield was slightly tilted backwards. The limousines either had wire wheels or the usual "artillery" wheels. In 1921, a heater could be fitted to the car. In June 1922 there was a second model introduced which had an increased condenser (parallel to built from this time successor).
The Dodge 30 was replaced with the Series 116. A total of 632,673 cars were built in six years.
