The Model 20 was introduced by Hupmobile in 1909. It was an immediate success due to its affordable price and reliability, competing with other low-cost cars of the time such as the Ford Model T. With a two speed manual transmission and power sent to the rear wheels, the Model 20 initially had a 2.2L inline four engine, but in 1911 displacement changed to 2.3L, increasing power from 16hp up to 20hp. The Hupmobile Model 20 was produced until 1912 when it was replaced by the Model 32.
