Overview

Colonial was an American luxury automobile marque produced in Chicago, Illinois, for a brief period between 1920 and 1921. It originated with Walden W. Shaw and John D. Hertz, owners of the Walden W. Shaw Livery Corporation, who sought to extend their transportation interests beyond taxicabs and into the production-car market. Their company controlled the Yellow Cab Manufacturing Company, giving the project an industrial and commercial connection to the well-known Shaw and Yellow Cab transportation businesses. The automobile was initially introduced as the Shaw during Chicago Automobile Show week in February 1920 at the Hotel Congress. The founders concluded that the Shaw name, strongly associated with taxicabs, was not an ideal identity for an expensive private automobile. They therefore changed the model's name to Colonial. The new name was intended to support a more prestigious positioning, although it was not entirely distinctive because other automobile manufacturers had previously used Colonial as a marque. Colonial was conceived as a large luxury touring car. It used a 136-inch wheelbase and was offered in configurations seating two, four, or seven passengers. Its listed price was $5,000, placing it at the high end of the American automobile market of the period. The car's engineering specification also changed during its short production life. The original plan called for a four-cylinder Rochester-Duesenberg engine, but by July 1920 the company had substituted a Weidely twelve-cylinder unit. The change appears to have been intended to strengthen the car's sales appeal by associating it with the prestige and smoothness commonly attributed to multi-cylinder luxury cars. The Colonial identity lasted only through the end of 1921. By the time of the 1921 Chicago Automobile Show, John D. Hertz had assumed complete control of the company. The same basic automobile was presented with a Continental engine and a new marque, Ambassador. As a result, Colonial was not developed into a long-running independent brand; it became an interim name in the transition from the original Shaw automobile to the Ambassador. The marque is therefore notable primarily for its connection to the early automobile activities of the Walden W. Shaw Livery Corporation and John Hertz, rather than for a sustained product range or long-term market presence.

History

Colonial emerged from an attempt by Walden W. Shaw and John D. Hertz to move from transportation services into the manufacture of private luxury automobiles. The two men owned the Walden W. Shaw Livery Corporation, which also owned the Yellow Cab Manufacturing Company. Their existing association with taxicabs provided manufacturing and distribution experience, but it also created a branding problem: the Shaw name was widely recognized in connection with taxis and did not necessarily communicate the exclusivity expected from a costly private car. The new automobile was unveiled as the Shaw at the Hotel Congress during the week of the Chicago Automobile Show in February 1920. Soon afterward, the name was changed to Colonial. The rebranding sought to separate the luxury car from the taxi business and establish a more suitable identity for the premium market. Colonial was nevertheless a relatively generic automobile name, having already been used by other makes. The car was a substantial touring automobile with a 136-inch wheelbase. Customers could choose bodies configured for two, four, or seven passengers. Its $5,000 price placed it among expensive American automobiles of the early postwar period. The initial engineering plan specified a four-cylinder Rochester-Duesenberg engine. During 1920, however, the company replaced that unit with a Weidely twelve-cylinder engine. The change reflected the period's emphasis on cylinder count as a signal of refinement, power, and prestige. Colonial production and marketing were short-lived. By the time of the 1921 Chicago Automobile Show, John D. Hertz was in complete charge of the company. The same basic automobile was presented with a Continental engine and was given the name Ambassador. This transition effectively ended Colonial as a separate marque by the close of 1921. The brand's history is consequently defined by a single luxury touring-car line, a rapid change in engine specification, and a sequence of name changes from Shaw to Colonial and finally Ambassador.

It was available in bodies seating two, four, or seven occupants and carried a listed price of $5,000. The car was initially planned with a Rochester-Duesenberg four-cylinder engine, but the specification changed to a Weidely twelve-cylinder engine during 1920. In 1921, the same basic automobile was reintroduced under the Ambassador name with a Continental engine.
