Kenworth T600 Model Overview

Who would have thought the Kenworth T600 was built for fuel economy and not for being the best-looking rig at the time!

The Kenworth T600 brought a whole new look to the trucking industry in 1985, dubbed the “Anteater”, this new model from Kenworth/PACCAR accounted for 40% of Kenworth’s semi-truck sales that year.

When compared to its predecessor, the W900, the new body style of the T600 helped minimize wind drag, allowing the T600 to carry the same payload at the same speeds, but with one hundred less horsepower. This meant less fuel consumption for the same weight and distance, saving owners significant amounts of money.

According to our friends at
“An engineering team led by the late Larry Orr, then PACCAR’s R&D chief, strived to design a tractor that would be aerodynamic enough to be significantly more fuel-efficient than a long-nose conventional (it was— by a whopping 22%) yet deliver all the other attributes expected of a freight hauler.

Orr’s team also gave the sloped-hooded Anteater— the nickname awarded it by truckers– a set-back front axle to improve front-axle loading and a much smaller turning radius than other conventionals. And the T600’s sleek design also threw off 50% less splash and spray than other models.” – source The Most Beautiful Curve

Kenworth T660

Kenworth introduced the T660 in 2007.  The difference between the Kenworth T600 and T660 is the T660 changed the diesel engines to those produced by PACCAR and changed the aerodynamics of the hood and fenders.  It introduced composite headlamp in the fenders, as well as changing the grille to be similar to the T2000 conventional.  Another major change was to the frame and suspension.
