Today at the Mid-America Trucking Show, Kenworth announced the all-new T680 tractor, a truck the company is calling its most aerodynamic truck ever. Highlights of the truck include a lower total cost of ownership. The T680 is designed for 1.5 million mile vehicle life, and features a 10-percent more aerodynamic performance and 5 percent more fuel efficiency compared to the T660. The tractor is made from lightweight stamped aluminum for reduced weight and an easy-to-service design.

For the driver, the T680 features bi-xenon forward lighting, a 30-percent larger door and 40-percent quieter interior environment. Perhaps the most innovative interior cab feature is the rotating passenger seat that allows for a much larger work/live environment for the driver.

The T680 interior also features 65 percent more storage, an the 83-inch-wide cab allows for a full 2 feet of space between seats.

T680 production begins May 21.
