The truck, developed jointly with electric commercial vehicle startup Thor Trucks Inc, is expected to be deployed later this year, UPS said on Tuesday.

The truck will have a driving range of about 100 miles, with lightweight battery designed and built by Thor.

UPS will test the class-6 delivery truck for the first six months, including its battery capacity and technical integration, after which UPS may buy more of these trucks.

This will be a part of UPS's plan of about 9,300 low-emission vehicles, including all-electric, hybrid electric and CNG, to understand which technology works best for some routes.

UPS has partnered with Workhorse Group Inc to build an all-new electric delivery van and it also has pre-ordered 125 electric semi-trucks from Tesla Inc.

Vehicle manufacturers such as Daimler and Navistar International Corp, and a slew of new entrants, are racing to overcome the challenges of substituting batteries for diesel engines in delivery vehicles as regulators crack down on carbon dioxide and soot pollution.
