New Research Says Heavy-Duty Hybrid Trucks Deliver on Fuel Economy
A performance evaluation of Class 8 hybrid electric tractor-trailers compared with similar conventional vehicles by the U.S. Dept. of Energy's National Renewable Energy Laboratory shows significant improvements in fuel economy.
“During our 13-month study, the hybrid tractors demonstrated 13.7% higher fuel economy than the conventional tractors, resulting in a 12% reduction in fuel costs for the hybrids,” said NREL Senior Project Leader Michael Lammert.
