SuperTruck Barreling Down the Road of Sustainability


Twelve miles per gallon. While that might not seem very high, it's double the fuel efficiency of typical heavy-duty tractor-trailers - also known as Class 8 trucks - which haul about 80 percent of the nation's goods. This improved fuel efficiency is a big breakthrough for the Energy Department's SuperTruck initiative, in partnership with industry, which aims to boost freight efficiency by 50 percent compared to a baseline vehicle. One SuperTruck partner, Daimler Trucks North America, recently shattered this goal with their Freightliner truck.

Heavy-duty trucks consume about 20 percent of America's total transportation fuel. This means improving the fuel efficiency of these vehicles can go a long way to reducing our nation's dependency on oil and lowering carbon emissions.

Engineers and researchers from the four separate SuperTruck teams - Cummins, Daimler Trucks North America, Navistar and Volvo - are using several technologies to make heavy-duty trucks more sustainable. Here are a few examples:

If all Class 8 trucks used SuperTruck technologies, we could lower oil use by an estimated 300 millions of barrels per year and individual truck operators could save about $20,000 a year on fuel.
