FedEx has placed an order for 2,000 electric delivery trucks from U.S.-based vehicle manufacturer Harbinger in a deal valued at more than $300 million. The company plans to deploy the vehicles across its pickup and delivery operations in the United States and Canada as part of its fleet electrification program.

The order includes a range of Class 5 and Class 6 medium-duty electric trucks that will replace existing diesel-powered vehicles. Harbinger expects to manufacture and deliver all 2,000 trucks by the end of 2027. The company’s Canadian dealer, Kaizen Automotive Group, will support vehicle deployment in Canada.

The agreement expands an existing relationship between the two companies. FedEx previously introduced Harbinger electric vehicles into its delivery network and co-led the manufacturer’s $160 million Series C funding round. The latest order will increase the number of electric vehicles operating within FedEx’s fleet as the company works toward its goal of fully electrifying its pickup and delivery fleet by 2040.

Harbinger estimates that each electric truck could reduce annual diesel fuel expenses by approximately $20,000 compared with a conventional vehicle. Based on a projected 20-year service life, the manufacturer estimates combined fuel savings of $800 million across the 2,000 trucks. It also projects that replacing the diesel vehicles could avoid more than 1.7 million tons of carbon dioxide emissions over their operating lives.
