Study: Boosting Torque Ratings Improves Fuel Economy of Truck Fleets


Truck fleets often use engines too small for their appli­ca­tions think­ing they can reduce acqui­si­tion and oper­at­ing costs. Dri­vers over revving these engines to com­pen­sate actu­al­ly reduce fuel econ­o­my com­pared to using a slight­ly larg­er torque engine with prop­er gear ratios for the appli­ca­tion.
