Around the Block in the First UPS Hydraulic Hybrid Vehicle

The UPS HHV in actionHydraulic Hybrid is “Ready for Prime Time” 

I had a short ride through the streets of Atlanta yesterday in the prototype UPS HHV delivery vehicle (package car). We haven’t heard much about HHV technology, but after yesterday’s press conference in Atlanta, that is likely to change. How does the HHV vehicle work? How can you move a truck around just using hydraulics and a small diesel engine? This short video and illustration offers a good introduction (more detailed information to follow in subsequent posts).

HHV technology was developed by the Environmental Protection Agency’s National Vehicle and Fuel Emissions Laboratory in Ann Arbor, Michigan in partnership with Eaton Corporation under a Cooperative Research and Development Agreement signed in October of 2001. Navistar designed and built the chassis for the vehicle. Road testing by UPS under real world conditions have proven the technology works in real-world conditions. With the first 7 vehicles now on order for deployment throughout 2009, further testing is now possible, leading to the scaling up the concept as one global solution to energy efficiency and emissions reductions in delivery vehicles, shuttle busses, and other short-haul urban duty cycles.
