The truck’s story began in 1923 when Harry W. Kent and Edgar K. Worthington incorporated the Gersix Motor Company as “Kenworth” – a combination of the founders’ last names.
In its first year, the small Seattle truck manufacturer produced 78 six-cylinder, gasoline-powered trucks. In the 90 years since, Kenworth has produced more than 900,000 trucks.
“Over the past 90 years, Kenworth has played an essential role in the development of trucks that are more fuel efficient, productive and economical to operate,” Gary Moore, Kenworth’s general manager and PACCAR vice president says. “Kenworth takes great pride in our history of achievement and excellence.”
In 1933, Kenworth became the first truck manufacturer to install diesel engines as standard equipment, and sold the first sleeper cab three years later. The Kenworth T600A became the first truly aerodynamic Class 8 truck in 1985.
In 2013, Kenworth says it expects to bring the company’s latest industry-leading innovations to the Mid-America Trucking Show in March. Throughout the year, Kenworth says it will also host many customer events to commemorate the company’s 90th anniversary milestone.
