UPS Low-Emission Hybrid Vehicles

One of these hybrid delivery vans just delivered a package - it looked and sounded pretty much like any other UPS truck (except for the UPS Low-Emission Hybrid Vehicle logo). This is a great way to evolve technology - get it in use daily and see what squeaks - then fix the problems, and do it again. UPS seems to do a good job of incorporating appropriate new technologies more quickly than other large companies - kudos to them!

UPS: Press Release:
"ATLANTA, May 22, 2007 - UPS (NYSE:UPS) today announced its fleet of alternative-fuel vehicles - already the industry's largest - had expanded with the deployment of 50 next-generation hybrid electric delivery trucks.

The 50 hybrid electric vehicles (HEVs) will operate in Atlanta, Dallas, Houston and Phoenix. These new trucks join roughly 20,000 low-emission and alternative-fuel vehicles already in use.
. . .
The new hybrid power system allows UPS to use a smaller diesel engine than would be required in a conventional delivery truck, thus saving on fuel and pollution-causing emissions. A battery pack, motor/generator and power control system are added, which allows electric power to be fed into the powertrain when conditions demand it, providing further savings.

The hybrid electric vehicles also use what is known as regenerative braking, meaning the energy generated when stopping the moving vehicle is captured and returned to the battery system as electrical energy. The efficient, computer-controlled combination of clean diesel power, electric power and regenerative braking allows dramatic improvements in fuel savings and emissions reductions."
