Latest UPS_HEV expansion brings UPS Green Vehicle Fleet to 2,060. [fimg=left]http://www.cleanmpg.com/photos/data/501/2009_UPS_Diesel_HEV.jpg[/fimg]Wayne Gerdes - CleanMPG - May 30, 2010 UPS HEV delivery trucks – Up to 35% fuel and emissions savings… No word on the upfront expense however. UPS announced that its fleet of alternative-fuel vehicles had expanded with the deployment of 25 next-generation hybrid electric delivery trucks to Long Island. Currently, 50 UPS hybrid electric vehicles (HEVs) operate in Atlanta, Dallas, Houston and Phoenix. The 25 trucks deployed here are part of 200 new HEVs deployed recently to eight U.S. cities. They join the roughly 20,000 low-emission and alternative-fuel vehicles already in use by UPS. The 200 new trucks will operate in Austin, Houston, Philadelphia, Chicago, Washington, D.C., Long Island, Minneapolis and Louisville. The 200 new HEV package cars are expected to reduce fuel consumption by roughly 176,000 gallons over the course of a year compared to an equivalent number of traditional diesel trucks. Since 2000, UPS’s fleet of alternative-fuel vehicles has traveled more than 165 million miles. The UPS alternative fuel fleet utilizes multiple technologies, including compressed natural gas, liquefied natural gas, propane, electricity and hydraulic hybrid technology. These green vehicles provide the “last mile” of service to deliver packages in the most environmentally sustainable way possible. The alternative fuel fleet, however, is just one part of UPS’s larger sustainability program. UPS provides its delivery services through an integrated network, meaning it uses only one vehicle to deliver all types of packages going to the same address. And unlike other competitors, UPS has developed a network that can leverage all modes of transportation from rail to truck to aircraft, optimizing package routes and improving fuel efficiency. “Collectively, this new HEV fleet can yield a 35 percent fuel savings, the equivalent of what’s used in a year to power 100 conventional delivery vehicles,” said Bob Stoffel, UPS senior vice president of supply chain, strategy, engineering and sustainability. The new hybrid power system utilizes a conventional diesel engine combined with a battery pack, saving fuel and reducing pollution-causing emissions. The small diesel is used to recharge the battery pack and to add power when necessary. HEVs use regenerative braking. The energy generated from applying the brakes is captured and returned to the battery as electricity. The combination of clean diesel power and electric power, supplemented by regenerative braking, allows dramatic improvements in fuel savings and emissions reductions. The HEVs use a Freightliner Custom Chassis Corporation body and a hybrid power system from Eaton Corporation. The external truck bodies are identical to UPS’s other signature brown trucks, although they feature additional labeling identifying them as hybrid electrics. The trucks use Li-Ion batteries, which offer a faster re-charging capability and last longer than previous generation HEV batteries. Additionally, these vehicles are much quieter than conventional UPS trucks.
