Truck efficiency solutions
Trucks are a necessary and cost-effective part of America’s freight transport system. Whether purchasing new trucks or making off-the-shelf modifications to existing trucks, a few simple choices make it possible to carry more freight with less fuel and fewer emissions.
Recommended actions, applicable to regional, vocational & long-haul trucks:
I. Operations solutions | More info
Driver training: Savings of 5 to 20 percent
Reducing highway speed: Lowering highway speed by 5 mph can save 7 percent or more
Reduce vehicle miles traveled (VMT): Cut total VMT with fewer empty trips
II. Tire solutions | More info
Wide-base tires: Fuel savings of up to 10 percent, plus reduced truck weight. Wide-base tires are snow-capable and are available in on/off road versions.
Automatic tire inflation systems: Save fuel and reduce costly maintenance
III. Technology solutions | More info
Idle reduction: New cab comfort technologies save up to 8 percent
Improved aerodynamics: Retrofits save up to 10 percent, depending on truck and routing
Weight reduction: Lighter trucks mean more payload and less fuel
Fleet modernization: Newer trucks are more efficient and much less polluting
III. Real-World Examples | More info
Wide-base tires: Save 910 gallons/yr, payback in 2 years
Idle reduction: Save 900 gallons/yr, payback in 1 to 3 years
Trailer side skirts: Save 910 gallons/yr, payback in less than 2 years
High-efficiency long-haul truck: Achieves 8 mpg, compared to 6 mpg industry average.
