Overview
The Studebaker Big Six was an automobile produced by the Studebaker Corporation of South Bend, Indiana between 1918 and 1926, being designated the Model EG (1918–21), the EK (1922–24) and the EP (1925–26); its name was due to the 127" wheelbase in comparison to the Studebaker Special Six at 120". In 1927, it was renamed the President (ES) pending introduction of a smaller and smoother straight-eight engine for new top-of-the-range models after January 1928.
Early models
All Studebaker models for 1918 represented an important milestone for the automaker because they represented a clean break from the legacy of E-M-F Studebaker had been producing.
Between 1918 and 1920, the Big Six was offered only as a four-door touring car, the most popular body style for automobiles at the time. As the price of enclosed cars came down and consumers discovered the benefits of closed and semi-closed passenger compartments, a wider variety of body styles was made available beginning with the 1921 model year. By 1926, the Big Six was available in a variety of body styles, including a dual-cowl Phaeton and a Berline (sedan).
