UPS is deploying 130 hybrid-electric vehicles (HEV) to its U.S. fleet, bringing it to more 380 such vehicles. The package-delivery giant has more than 2,000 alternative-powered vehicles in its fleet.

The vans are Freightliner Custom Chassis trucks with a hybrid power system from Eaton Corp. They will operate in California, New York, and New Jersey.

UPS said it expects to save 58,371 gals. of fuel annually with this deployment, representing a 30% fuel economy savings, and reduce CO2 emissions by 592 metric tons.

When combined with the 250 HEV delivery trucks already in operation, UPS expects to reduce fuel consumption by approximately 191,000 gal. a year and cut CO2 emissions by over 1,700 metric tons.
