The W900 is a Kenworth class 8 truck model, known for its long-nose style.
The engine sizes for the W900 range from 9 liters to 15 liters, and it accommodates up to a 600-horsepower engine. The W900 has front axles from 12,000 to 22,000 lb ratings, and rear axles from 23,000-lb single to 58,000-lb tandems.
A much more aerodynamic truck based on the W900 was made by Kenworth: the T600. Introduced in 1986, this model had up to 22% better fuel economy over the W900[2]. The T600 was not intended as a direct successor to the W900, and as such, KW sold the two models alongside each other. The T600 was sold from 1986 until its replacement in 2008 by the Kenworth T660.
