Automobile \Au`to*mo"bile\, n. [F.]
   An automobile vehicle or mechanism; esp., a self-propelled
   vehicle suitable for use on a street or roadway. Automobiles
   are usually propelled by internal combustion engines (using
   volatile inflammable liquids, as gasoline or petrol, alcohol,
   naphtha, etc.), steam engines, or electric motors. The power
   of the driving motor varies from about 4 to 50 H. P. for
   ordinary vehicles, ranging from the run-about to the touring
   car, up to as high as 200 H. P. for specially built racing
   cars. Automobiles are also commonly, and generally in British
   usage, called {motor cars}.
