The 1914 Grand Prix season consisted of Grand Prix races across Europe and the United States until abbreviated by the outbreak of World War I. The Vanderbilt Cup and the American Grand Prize were held again after a year’s abeyance, this time raced at Santa Monica, California. European cars arrived in force to contest the Indianapolis 500. French cars dominated the race taking the top four places with victory going to René Thomas in a Delage. The unofficial AAA national championship would be awarded to Ralph DePalma. It proved to be the last major race before war overtook Europe in August 1914.
