UPS adds Hydraulic Hybrid Delivery Vans

A new type of hybrid is being deployed that has demonstrated 45% fuel economy improvements. The new hybrid demonstrates the success of public-private partnerships that include the U.S. EPA, Calstart, Eaton, and Navistar. With a diesel “series” hydraulic hybrid of the type being purchased by UPS, a high-efficiency diesel engine is combined with a unique hydraulic propulsion system, replacing the conventional drivetrain and transmission. The vehicle uses hydraulic pumps and hydraulic storage tanks to capture and store energy, similar to what is done with electric motors and batteries in a hybrid electric vehicle. UPS will soon have over 2,000 hybrids and natural gas vehicles.
