UPS announced a new project of updating 125 step vans with new Workhorse E-GEN series hybrid drivetrains as part of the company’s broader Rolling Laboratory approach.

Deployment in Alabama, Arizona, Georgia, Florida, Mississippi, Nevada, Ohio and Texas is scheduled for later this year.

By the end of 2017, UPS intends to reach a total of 1 billion miles logged with alternative fuel and advanced technology vehicles. The company earlier experimented also with other type of plug-in vehicles.

The Workhorse E-GEN is equipped with a 200 kW Sumo electric motor and a 60 kWh battery pack (45 kWh usable) consisting of some familiar Panasonic 18650 cells, as well as a small 2-cylinder, 23 kW/30 hp engine.  So not the traditional plug-in hybrid we see in passenger vehicles with specific all-electric ranges, but rather a set-up to maximize economy over a delivery day.

"A compact, quiet-running 2-cylinder engine replaces a prior 4-cylinder engine to extend their range, improve performance and fuel efficiency. The updated trucks deliver significant fuel economy equivalency gains – up to four times the fuel economy of a gasoline-powered vehicle."

Carlton Rose, UPS Global Fleet Maintenance and Engineering president said:

“These vehicles are a great example of the impact our Rolling Lab approach is having. Our real-world testing of this new technology revealed opportunities to improve its performance and efficiency, which led to the development of a more advanced propulsion system.”

Steve Burns, CEO of Workhorse said:

“These low-emission trucks are designed specifically to meet the stop and start needs of UPS’s urban delivery routes, while driving unprecedented fuel and maintenance savings. This new system enables the vehicle to accommodate UPS’s typical route on battery energy and uses a very small internal combustion engine to add additional energy to the batteries when and if needed and eliminates range anxiety.”
