Harry C. Stutz is considered a pioneer of the transaxle principle, what e.g. includes the transition from chain to shaft and gear drive. He also said to have very busy with the four-cylinder engine during his career at American Motors and Marion, before he started up his own business. It is not surprising that his company just installs these two features in vehicles since 1909.

An important goal of these innovations is to participate in racing, the after incredible five weeks construction period in Indianapolis will be completed very respectable for a newcomer with a 11th place. The cars are called Bearcat from now on, long, perhaps too long selling the four-cylinder.

For ten years, there are the Bearcats, now has become the 'Stutz Motor Car Company'. The sale runs into trouble, the top management board changes. It was not until 1923, a six-cylinder engine comes on the market, 1926 followed by an in-line eight-cylinder. The competition offers more favorable, there does not help either the new safety glass of the windscreen.

In addition, of course, the economic collapse after the stock market crash of 1929. After all, there is an R-8 with four valves per cylinder from 1931. Stutz himself has meantime founded two other companies, a "Fire Engine Company 'and one for the construction of vehicles for the medium price segment. But times are hard for car producers.

The companies are initially only partially successful. Harry C. Stutz dies in 1930, he is active neither in these nor in the Stutz Motor Car Company. This survived until 1939.
