Kenworth
American truck manufacturer
Kenworth Truck Company is an American truck manufacturer. Founded in 1923 as the successor to Gersix Motor Company, Kenworth specializes in production of heavy-duty (Class 8) and medium-duty (Class 5–7) commercial vehicles. Headquartered in the Seattle suburb of Kirkland, Washington, Kenworth has been a wholly owned subsidiary of PACCAR since 1945, operating alongside sister company (and marketplace rival) Peterbilt Motors.
Kenworth marked several firsts in truck production; the company introduced a raised-roof sleeper cab, and the first heavy-duty truck with an aerodynamically optimized body design. The Kenworth W900 has been produced continuously since 1961, serving as one of the longest production runs of any vehicle in automotive history. The K100 was also released in 1961.
History
1912-1923: Gerlinger Motors
Kenworth traces its roots to the 1912 founding of Gerlinger Motors in Portland, Oregon; the company was a car and truck dealership owned by brothers George T. Gerlinger and Louis Gerlinger, Jr. In 1914, the brothers expanded into vehicle manufacturing, marketing a truck named the Gersix. Deriving its name from its inline six-cylinder engine (one of the first trucks equipped with the type), the Gersix was framed in structural steel, intended for commercial use.
While the first vehicle was completed largely as a side project, the heavy-duty construction of the Gersix found itself in demand by loggers in the Northwest.
