Following five year’s of development through the U.S. Department of Energy’s SuperTruck program, Volvo’s SuperTruck concept vehicle demonstrated more than 12 mpg during on-road testing, about twice the fuel efficiency of the average heavy-duty on-highway tractors.
Volvo’s SuperTruck combines advanced aerodynamics, vehicle and powertrain technologies to achieve a freight efficiency improvement of 88 percent – exceeding the 50 percent improvement goal set by the U.S. Department of Energy.
From the top-of-cab solar panels powering its battery and interior lights, to its ultra-light aluminum frame and highly advanced 425 horsepower 11-liter proprietary engine, the SuperTruck concept vehicle allowed Volvo engineers to push the boundaries of heavy truck efficiency. The sleek tractor-trailer combination boosted fuel efficiency by 70 percent in road tests, and powertrain brake thermal efficiency reached 50 percent.
