This is a list of vehicles of the Auburn marque produced by the Auburn Automobile Company between 1903 and 1936. Included are vehicles produced, beginning in 1900, by Frank and Morris Eckhart before they formally established Auburn in 1903. The company produced vehicles in Auburn and Connersville, Indiana.
Auburn began production with 8 automobiles in 1900. Production reached 4,044 in 1925 and peaked at 34,228 in 1931, but then declined drastically with only 1,263 vehicles produced in 1936. Sources list no vehicle production in Auburn's final year (1937).
(total): 179,918
The first Auburn vehicles were equipped with single-cylinder engines. Beginning in 1905, 2 cylinders were offered; then 4 cylinders in 1909; 6 cylinders in 1912; 8 cylinders in 1925; and finally 12 cylinders in 1932. Auburn also added a supercharged 8-cylinder engine during the last two years of production. Auburn sourced engines from various companies. During its first two decades, Auburn used Rutenber, Teetor, and Continental engines. In 1923, Auburn used Continental engines for the 6-43 and Weidely engines for the 6-63. In 1925 and later years, Auburn used engines by Lycoming.
Auburn model numbers started out with basic numbering and lettering schemes. A two-part numbering scheme was phased in beginning in 1912 (with the model 6-50). In this scheme, the first number referred to the number of cylinders and the second number (often imprecisely) referred to the engine's horsepower: the model 6-50 of 1912 had 6 cylinders and offered 50 horsepower, and the model 4-38 of 1917 had 4 cylinders and 38 horsepower. However, these designations were not strictly followed. For example, model 6-80 of 1929 had a 6-cylinder engine but only offered 65 horsepower, and the model 12-165 of 1933 had 12 cylinders and offered 160 horsepower, etc.
Model numbers sometimes vary between references and vehicle literature, such as "Model 120" vs. "8-120" for the same 1929 vehicle, or "Model 653" vs. "6-653" for the same 1935 vehicle. The list below follows the two-part numbering system for consistency after it was phased in (circa 1912), noting alternate designations if known.
Auburn occasionally used model names, such as the "Union" of 1916-17 and the "Beauty Six" of 1919âÂÂ22. From the year 1931, packages such as Standard, Custom, Salon, Custom Dual Ratio, Salon Dual Ratio, and Supercharged Dual Ratio were designated, in addition to model numbers and body styles.
This list is chronologically sorted year over year, but can be re-sorted to search for specific model numbers. See also the "model number cross-reference" below. The list includes wheelbase in inches, number of cylinders, horsepower, engine type and size in cubic inches (sometimes specifying carburetor barrels), body styles offered in that year (at that wheelbase), and other information if available.
