The Studebaker Big Six was a series of luxury cars introduced in 1918. The Big Six was Studebaker's top model during its production, being placed above the Light Six and Special Six. It featured a 5.8L inline six engine that produced 60hp until 1926, when improvements saw power increase to 75hp. For the first two years of production, the only body style available was a five passenger tourer, but from 1921 onwards, market demand saw the addition of more body styles, including phaeton and limousine. Production of the Big Six lasted until 1926, when the model was replaced by the Studebaker President.
