FedEx Gasoline Hybrid Electric Delivery Trucks
In April 2009, the Fleet Test and Evaluation team launched its year-long technology evaluation of FedEx gasoline hybrid electric (gHEV) parcel delivery trucks operating in and around Los Angeles. The team collected and analyzed fuel economy, maintenance, and other on-road vehicle performance data on three gHEV trucks and three conventional diesel trucks. They also tested these vehicles at NREL's ReFUEL Laboratory to determine the fuel economy and emissions benefits gained through hybridization.
Compared to the conventional trucks, the gHEV trucks demonstrated substantially reduced tailpipe emissions and similar fuel economy, except during the highest intensity drive cycle when the gHEV exhibited about 20% higher fuel economy.
