Illinois-based Navistar International Corp. has deployed an all-electric delivery truck that was developed with the help of a $39 million grant from the American Recovery and Reinvestment Act. Navistar intends to build 400 of the all-electric trucks at its facility in Elkhart, IN during its first year of production, and the company expects to produce several thousand vehicles per year in the next few years.
The all-electric truck was designed for maximum efficiency and environmental friendliness, producing zero tailpipe emissions. Navistar designed the vehicle to travel 100 miles before a recharge. It is intended primarily for fleets and commercial truck users in congested, urban environments where stop-and-go driving would otherwise consume a large amount of fuel.
