FedEx has placed a binding order for 2,000 all-electric medium-duty trucks from California-based manufacturer Harbinger, with a total value exceeding $300 million. Harbinger calls it one of the largest binding orders for electric medium- or heavy-duty trucks in history.

Deliveries are scheduled to be complete by the end of 2027. FedEx plans to deploy the vehicles across its pickup and delivery operations in the U.S. and Canada, where they will replace conventional fleet units as part of the company's electrification strategy.

The order builds on an initial purchase of 53 Harbinger electric vehicles by FedEx in November 2025. FedEx also co-led Harbinger's $160 million Series C funding round.

Harbinger, founded in 2021, designs and manufactures a proprietary electric vehicle stripped chassis that supports popular medium-duty body types, including commercial walk-in vans, recreational vehicles and box trucks. The company builds all major vehicle systems in-house in the U.S. and targets acquisition parity with comparable gasoline- and diesel-powered vehicles.

The economics of the deal rest on fuel savings. Harbinger estimates each of its electric trucks cuts fuel costs by an average of $20,000 annually compared with the diesel vehicle it replaces. Scaled to 2,000 vehicles in North America, that works out to roughly $40 million in annual fuel savings, or $800 million over a typical 20-year vehicle life. The company also projects the fleet will avoid more than 1.7 million tons of CO2 emissions.

John Harris, co-founder and CEO of Harbinger, said the order validates fleet electrification on commercial terms.

"FedEx is demonstrating that the business case for incorporating electric vehicles into real-world fleet operations at scale makes sense," Harris said. "Our previous work together gave FedEx firsthand experience with the performance and economic advantages Harbinger vehicles can deliver."

FedEx has committed to carbon-neutral operations by 2040, backed by a target to convert its entire parcel pickup and delivery fleet to zero-emission electric vehicles. The 2,000-truck order represents a binding step toward that deadline, with hard delivery dates attached.

Vinay D'Souza, senior vice president of global assets and infrastructure at FedEx, framed the purchase as part of a structural shift in freight transport.

"The transportation industry is undergoing a fundamental transformation, and electrification is set to play a pivotal role in the future of commercial fleets," D'Souza said. "This order with Harbinger helps us advance that transition, allowing us to build a more modern, efficient, and intelligent fleet that meets the evolving needs of our customers, our team members, and our global operations."

For Harbinger, the order converts a startup chassis platform into a production commitment with a fixed 2027 delivery window and a customer with a 2040 fleet-decarbonization target. Whether the company can scale U.S. manufacturing to meet 2,000 units on schedule — and whether the promised $20,000-per-truck fuel savings hold up in FedEx operations — will determine the credibility of the deal's $800 million lifecycle economics claim.
