In a move that could shake up North American heavy truck design, International introduced its latest Class 8 road tractor, the LoneStar, at the Chicago Auto Show last month. Officially, LoneStar is described as an "advanced classic," combining bold styling that normally appeals to owner operators and other premier truck buyers with fuel-saving aerodynamics popular among large fleet managers. International executives said they believe the truck will find favor across a large swath of potential customers, but they clearly stated that it will be positioned -- and priced -- on par with the leading, square-nose conventional products built in Texas and Washington. The truck, which borrows some chassis, electrical and body panel components from existing parts bins, is bold and angular -- some might even say aggressive and imposing. The interior is just as revolutionary. In developing it, engineers completely rethought the work-space/living-space relationship.
