The Model S was the first four-seat passenger car produced by Oldsmobile in 1906, offered as a larger alternative to the Model R Curved Dash runabout that appeared in 1901.{{cite book |last=Georgano |first= G.N. |authorlink= G.N. Georgano|title=Beaulieu Encyclopedia of the Automobile |year=2000 |publisher=HMSO |location=London |isbn=1-57958-293-1}}{{page needed|date=January 2024}} The advertised price was $2,250 (${{formatnum:{{Inflation|US|2250|1906}}}} in {{Inflation-year|US}} dollars {{inflation-fn|US}}). It was Oldsmobile's first four cylinder car and took the top level marketing position above the Model L and the entry-level Model R. It was one of the last independently developed products before they joined General Motors in 1908, and competed against Buick, Ford and other automakers at the time. It was built at the Oldsmobile factory in Detroit and developed by Frederick and Angus Smith, whose father Samuel L. Smith was the primary investor, and R. E. Olds had left the company due to an argument with Oldsmobile Board of Directors.
