This article is about an automobile built in Williamsport called the Imperial. In October 1905 N. Barrow Bubb started a garage. In November 1905, his two sons Harry A. and Nathan B. convinced their father to rent them the garage. This garage became to be known as the Williamsport Auto Exchange selling Reos, Whites, and Premier automobiles.

In the fall of 1906, the brothers began building a prototype automobile that was designed by C.P. Van Ferls, manager for the Williamsport Auto Exchange.

In early 1907, another firm was started to help secure funding to build the prototype. The firm was named the Williamsport Engineering Company. The main investors being the Bubb brothers and their uncle Harry C. Bubb. The prototype was completed and tested in the spring of 1907.

In August 1907 the Williamsport Engineering Company and the Williamsport Auto Exchange became the Imperial Motor Car Company.

The Imperial was a four-seat roadster (convertible) with a 5.5 liter four cylinder water-cooled engine built by Rutenber. The Imperial had a three speed manual transmission with shaft drive, and a 108-inch wheelbase. The Imperial weighed 2,400 lbs. and sold for $2,650. It must be noted from another reference source I have stated that Imperial came with a 35 HP four cylinder engine built by Milwaukee.

It is believed that 50 Imperials at best were produced before the company went out of business in September 1908.
