NREL Helping Delivery Cos. Switch to Hybrids
GOLDEN, CO - Delivery companies like FedEx and UPS are starting to gravitate to hybrid delivery trucks as a way to save money and help the environment.
The federally funded lab is evaluating how heavy-duty hybrid vehicles perform, gathering hundreds of data points including GPS coordinates, fuel economy and battery temperatures.
Kevin Walkowicz is a senior project leader with the lab. He says the goal is to compare the new models with the more conventional ones, considering costs for maintenance, reliability and emissions.
