In late 1909 Bobby's brother, Louis Gorham Hupp left his job with the Michigan Central Railroad in Grand Rapids and joined the company.

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.

[8] The valves were on the motor's left side, with spark plugs over the inlets and relief cocks over the exhaust.

Hale & Kilburn had pioneered the replacement of cast iron with pressed steel for many parts for the interiors of railway carriages.

Hale & Kilburn had built some body panels for King and Paige but Budd had grander aspirations the Hupp project would permit him to pursue.

The disassembled bodies were shipped by rail to Detroit where they were put back together, painted and trimmed in the Hupmobile factory.

[12] (This factory was demolished as part of site clearance for General Motors' "Poletown" assembly plant in the early 1980s.)

Carl Wickman, a car dealer in Hibbing, Minnesota, used an unsold 7-passenger model as the first vehicle for what became Greyhound.

With Hupmobile's low production volume, the result was that no model could be produced in sufficient quantity to achieve economy of scale.

1934 saw the introduction of a striking restyle called the "Aerodynamic" by Loewy, as well as the lower-priced series 417-W using Murray-built slightly-modified Ford bodies.

[16] A new line of six- and eight-cylinder cars was fielded for 1938, but by this time Hupp had very few dealers, and sales were disappointingly low.

Desperate for a return to market strength, on February 8, 1938, Hupmobile acquired the production dies of the Gordon Buehrig-designed Cord 810, paying US$900,000 for the tooling.

[17] Hupmobile hoped using the striking Cord design in a lower-priced conventional car, called the Skylark, would return the company to financial health.

Lacking adequate production facilities, Hupmobile partnered with the ailing Graham-Paige Motor Co. to share the Cord dies.

While each marque used its own power train, the Graham edition, called the Hollywood, differed from the Skylark in a few minor details.

They were one of the first U.S. automakers to equip their cars with "free wheeling", a device that enjoyed immense, but brief, popularity in automobiles in the 1930s.

In 1914, Eric Wickman tried to establish a Hupmobile dealership but could not sell them so he started transporting miners in one of the vehicles and founded Greyhound Lines.

[14] The National Football League was created at Ralph Hay's Hupmobile dealership in Canton, Ohio, in 1920.
