The Kenworth T660 is a class 8 truck model by Kenworth, first introduced in 2007. It is a shift in truck design from its cousin the Kenworth W900, which it is based upon. The difference between the two is its aerodynamic face lift, as well as major frame and suspension changes. The Kenworth T600 was the original model and the T660 replaces that. In 2016, Kenworth announced they were discontinuing the T660 in favor of the T680.
