TES T DRIVE A growing T family The Kenworth T680, though similar to its T660 and T700 brothers, forges new ground with a spacious, driver-focused interior. BY STEVE STURGESS The T680's design was based on extensive driver interviews and interactions in an adjust- able cabin space. This helped engineers to optimize comfort, usability and visibility. he number says it all. Kenworth's new and best- kept secret T680 falls midway between the T660 and the T700, launched a year ago. The 660 has the traditional Kenworth cab at 75 inches, the T700 has the 90-inch cab. The T680 falls in the middle at 83 inches, appealing to buyers for whom the narrow T660 cab is just too tight at the shoulders for easy access to the back into the sleeper. Sister-brand Peterbilt shares the basic cab construction in its corresponding 579, which was also launched this spring. Both are highly tooled stamped aluminum structures with complex panels joined by Henrob fasteners to create a rigid aluminum cab structure. The rivets are blind and no heads stand out on the smooth cab surface except at the rear corners. 50 OVERDRIVE JULY 2012 OVERDRIVE JULY 2012
