The driver-pleasing over-the-road tractor that drivers helped design. Unsurpassed ergonomics, with 11 full inches of seat travel, available tilt-telescopic steering column, and such thoughtful standard touches as finger-tip cruise control buttons in the steering wheel. Choice of three amenity-rich interiors. Wide selection of 10-liter through 15.8-liter diesels with ratings as high as 600 hp. A cab and front end assembly scrupulously styled for fuel-saving aerodynamic efficiency. A set-back front axle to enhance maneuverability and increase forward weight distribution to help maximize payloads.
