Kenworth rolled out a truck which changed the industry forever. Called the T600A, the truck was a sloped-nose conventional with a set-back front axle, a combination which gave drivers the comfort of a conventional and the manoeuvrability of a cabover. The T600A cut through the wind saving customers up to 22 percent on their fuel bills. Testing showed an aerodynamic improvement of 40 percent when compared to the company’s W900 conventional.
