The long and large history of the Kenworth W900

Since 1961, there has been some form of W900 available from Kenworth.

Ever wonder what the “W” stands for? It’s Worthington, the last name of one of Kenworth’s founders.

The first iteration of W900 lasted five years and was among the industry first to include a fiberglass roof panel. Kenworth has always prided itself of a rich heritage of engineering. That’s what happens when Boeing is your neighbor.

In 1967, Kenworth launched the fabled W900A. This was the first W9 to feature big power and some of the iconic features that the truck model is known for.

In 1976, Kenworth released the aerodyne sleeper, an iconic midroof with two large windows facing forward.

The age of the B model

From 1982 to present, the Kenworth W900 produced in the USA became classified as the “B” model. As a result of bigger power and more demand for cool air, the truck took on a new, taller look. The hoodline was raised to increase cooling capacity and the overall look of the W9 was forever changed.

2015 marked the 25th anniversary of a long hood variant Kenworth W900. As a result, the limited edition “ICON” model was released. Each truck in the series recieved a specific number and featured a special hood ornament.
