Hupp Motor Car Co. was founded in Detroit, Michigan by Robert and Louis Hupp in 1908.
The Hupmobile Model 20, a two-passenger runabout, was introduced at the 1908 Detroit Auto Show and had first-year sales of over 1,600.
The Hupmobile continued to do well into the 1920s and attracted good engineers, moving from a four-cylinder to a straight eight and producing a variety of models.
In 1926, the Hupmobile Six was added and Hupp's earnings increased.
In 1928, the stylish model helped the Hupp brothers afford to increase plant capacity by buying the Chandler-Cleveland Corp. of Cleveland, with 65,862 Hupmobiles produced by the end of that year.
In 1930, after the stock market crash, Hupp increased the power plant to a 70-horsepower Six and a 100-horsepower Eight, but sales dipped 23 percent and the Great Depression was looming.
Despite the challenging economic climate, Hupp introduced a 133-horsepower Eight in the early 1930s, which was not well-suited to an economy that couldn't afford additional gas consumption.
