UPS Hydraulic Hybrid Delivery Van Evaluation

NREL is evaluating the performance of 20 hydraulic hybrid delivery vans operated by the United Parcel Service (UPS) in the Baltimore, Maryland, area.

UPS added the vans to its fleet in 2012. Because UPS started using gasoline engines in all of its non-hybrid delivery vans in 2010, NREL is comparing the new hybrid vans, which run on diesel, to similar conventional gasoline vans.

The on-road portion of this evaluation includes collecting and analyzing duty cycle, use, fuel economy, reliability, and other vehicle performance data. The in-lab portion involves dynamometer evaluation at NREL's Renewable Fuels and Lubricants Laboratory to determine the fuel economy and emissions impact of the hydraulic hybrid technology.
