Aerodynamism and Peterbilt's Model 579 EPIQ tractor

A host of subtle yet significant aerodynamic enhancements - both visible and invisible to the naked eye - help "smooth" the airflow around Peterbilt's Model 579 EPIQ highway tractor and thus allow for continued improvements in fuel economy. Frank Schneck, Peterbilt's division engineering manager, recently provided American Trucker with an overview of those aerodynamic improvements to the Model 579 EPIQ package at the OEM's Denton, TX, manufacturing plant, explaining how they work to produce "smoother" airflow around both truck and trailer.
