Charter Mixed Vapor Car

The Charter Mixed Vapor car was supposed to run on a half-and-half mixture of gasoline and water, which was injected into the combustion chamber in atomized form. The gasoline exploded in the normal way and the water was converted into superheated steam, which was said to result in a longer and softer explosion. A four-passenger rear-entrance tonneau body was fitted to the car.[1]
