Truck designers are focusing more on components to help increase fuel efficiency , according to a report by ACT Research and Rhein automotive . The report reveals that innovations such as " air - smoothed hood and roof designs , bumpers with integrated air conditioning , rear fender skirts and rear cab mounted air fairings " are being implemented ahead of greenhouse gas emissions laws , which take effect from 2020 . Tom Rhein , President of Rhein Associates , said when aerodynamic refinements were combined with improved powertrains , fuel savings of up to 8 % could be made .
Truck designers are focusing more on aerodynamics to help increase fuel efficiency, according to a report by ACT Research and Rhein Associates. The report reveals that components such as "air-smoothed hood and roof designs, bumpers with integrated air dams, revised fender skirts and rear cab mounted air fairings" are being implemented ahead of greenhouse gas emissions laws, which take effect from 2018. Tom Rhein, President of Rhein Associates, said when aerodynamic refinements were combined with improved powertrains, fuel efficiencies of up to 8% could be made.
