====Model 20====

Hupp Motors obtained $25,000 (equal to ${{Inflation|US|25000|1909|fmt=c}} today) in cash deposits at the 1909 automobile show (the lowest capitalization of Detroit's eight major car makers<ref>Wise, p. 990.</ref>) to begin manufacturing the Hupp 20.  The first cars were built in a small building at 345 (now 1161) Bellevue Avenue in Detroit, Michigan. The company immediately outgrew this space and began construction of a factory a few blocks away at E. Jefferson Avenue and Concord, next to the former Oldsmobile plant.<ref>{{Cite news|title=Horseless Age|date=May 21, 1909|page=691}}</ref><ref>{{Cite news|title=Horseless Age|date=July 21, 1909|page=73}}</ref>  The company produced 500 vehicles by the end of the 1909 model year (the fall of 1909). Production increased to more than 5,000 in the 1910 model year.

The Model 20's pricing was set at $900.<ref name="gaz">{{cite journal |last1=Zellers |first1=Carl |title=Happy Birthday to a 1911 Hupmobile Model 20 |journal=HCCA the Gazette |date=Sep 2021 |volume=83 |issue=5 |page=50}}</ref> The touring automobile was built on the same principles as the roadster.<ref name="gaz"/> The Touring was nearly identical to the runabout aside from a longer wheelbase, a stronger frame, a stronger rear axle, and other critical pieces.<ref name="gaz"/>

The four-cylinder engine had a bore of {{frac|3|1|4}} inches and a stroke of 3 3/8 inches and was rated at 16 to 20 horsepower.<ref name="gaz"/> The valves were on the motor's left side, with spark plugs over the inlets and relief cocks over the exhaust.<ref name="gaz"/> The flywheel also served as a fan, and cars delivered to hot areas were equipped with an extra belt-driven fan.<ref name="gaz"/> The engine was lubricated with a unique Hupp system oil good for a 250 to 300-mile trip.<ref name="gaz"/>
The car had a 110-inch wheelbase and was fitted with 30&nbsp;×&nbsp;{{frac|3|1|2}}-inch tires in front and 31&nbsp;×&nbsp;{{frac|3|1|2}}-inch tires in the rear.<ref name="gaz"/> This model never became popular partly because of the low power and only a two-speed transmission with very wide-spaced ratios.<ref name="gaz"/> The low-speed ratio was 2.7 to one, and the high speed was direct reverse had the same ratio as the low, which meant that the car moved quite fast when it went backward.<ref name="gaz"/>
It had a distinct selling value in that the car was guaranteed to be free of material and workmanship problems.<ref name="gaz"/> Furthermore, the manufacturer would replace any damaged material at no cost except for the tires.<ref name="gaz"/>
