The Dodge Brothers began supplying parts and assemblies to automobile manufacturers. In 1914 they produced their first automobile, a Model 30 with a four-cylinder engine rated at 35 horsepower. The Model 30 had an innovative, all-steel body when most of the industry was still using steel panels and wooden frames.Twelve-volt charging systems were an improvement over standard six-volt charging systems, another improvement put forth by Dodge. In May of 1916, General Patten led a charge against Mexican revolutionary general Pancho Villa using Dodges, and in doing so vanquished three Villista lieutenants.
