Kenworth is an American company that manufactures medium and heavy duty trucks. It is a subsidiary of PACCAR Inc., a Fortune 500 company and one of the largest manufacturers of commercial vehicles in the world.
The first Kenworth brand truck was produced in Seattle in 1923. In 1933, Kenworth began installing diesel engines in all its trucks; it also produced its first sleeper cabs. During World War II, Kenworth continued building commercials while also producing war vehicles. By 1965 the company had opened a new factory in Kansas City and was producing more than 2,000 trucks per year.
Kenworth continued to expand and innovate throughout the ‘70s and ‘80s, introducing its T600 model in 1985. The T600’s aerodynamic design improved fuel efficiency by up to 22 percent. In 2012 Kenworth broke ground with its T680 model, setting a new industry standard for fuel economy and aerodynamics. Two years later the company marked production of its one millionth truck.
Kenworth’s product line includes 13 different models broken down into six divisions: on highway, vocational, medium duty, off highway/export, traditional and gliders. The company also offers parts and services.
In addition to its factories in the United States, Kenworth has production sites and subsidiary companies in Canada, Australia and Mexico.
