History

Based in Bellevue, Washington, it was founded in 1905 by William Pigott, Sr., as the Seattle Car Manufacturing Company. Its original business was the production of railway and logging equipment. Upon a subsequent merger with a Portland, Oregon firm, Twohy Brothers, Seattle Car Manufacturing Company became the Pacific Car and Foundry Company.

During the Second World War, it was involved in war production, including Sherman tanks for the U.S. Army.

Pacific Car and Foundry purchased Seattle's Kenworth Motor Truck Company in 1945 and both Peterbilt Motors Company and the Dart Truck Company 13 years later. In 1972 the corporate name was officially changed to PACCAR Inc, with the Pacific Car and Foundry Company name becoming a subsidiary division.

In 1981, PACCAR acquired Foden Trucks, a British manufacturer. Fifteen years later, in 1996, the Dutch DAF Trucks, at the time in financial difficulties, was acquired. and in 1998 PACCAR acquired the British Leyland Trucks for its light and medium truck (6 to 44 tonnes) design and manufacture capability.

With its Peterbilt, Kenworth, Leyland, Foden, and DAF nameplates, PACCAR ranks second in production numbers in the United States and third in production numbers globally in "big rig" truck production. The leading unit producer in the United States is Freightliner, a unit of DaimlerChrysler. Other major competitors in the heavy-truck business include Navistar, International, and AB Volvo.
