About T680
The Kenworth T680 is what a modern long-haul tractor looks like when fuel economy writes the brief and drivers get a vote on the interior. Introduced in the early 2010s as the brand's new aerodynamic flagship, it replaced the T660 and quickly became the Kenworth most likely to be seen hauling freight down an interstate at two in the morning, its sloped hood and wraparound windshield cutting through the air that every fleet accountant pays for by the gallon.
The truck has been reworked several times since, most notably with a next-generation version that smoothed the bumper, mirrors and hood further and brought a digital dash and a long list of driver-assistance systems. Under the skin it usually carries a Paccar MX-13 diesel and an automated transmission, though buyers can still spec to taste. Drivers praise the quiet cab and the roomy sleepers; critics note that more electronics means more things to diagnose on the side of the road.
The T680 now anchors Kenworth's alternative-power work too. The battery-electric T680E targets regional and drayage routes where trucks return to base each night, and fuel-cell versions built with Toyota have run in port service in Southern California. Its rivals are the Freightliner Cascadia, Volvo VNL, Mack Anthem, International LT and its own corporate cousin, the Peterbilt 579. Coverage here gathers the T680's updates, interior and cab packages, fleet orders, recalls, fuel-economy claims and the slow, expensive march toward zero-emission long haul, along with the wider Kenworth stories that shape the truck's world.
