Mack's "Super Econodyne" Spec

Mack Trucks Inc. recently rolled out a new "Super Econodyne" specification package for its Pinnacle line of Class 8 highway tractors designed to boost fuel economy and performance simultaneously. Few changes are noticeable to the naked eye as almost all of the "Super Econodyne" improvements come from new customized software improving the engine-transmission-drive axle linkages.
