September 2026 became the largest month for U.S. electric truck orders since tracking began, with more than 4,500 medium- and heavy-duty vehicles committed by fleets and shippers. The headline numbers included a record 2,500-truck Class 8 order, a 2,000-van order from FedEx, and more than 70 Tesla Semi deployments. Here’s the roundup.
The biggest news was a 2,500-vehicle order for electric Class 8 trucks assembled by Catalyst Mobility, the organization formerly known as CALSTART, and Smart Freight Centre through the ZET SCALE alliance. The order nearly doubles the number of electric Class 8 trucks currently operating in the United States.
The base vehicle is the Tesla Semi, but the framework allows Kenworth and Volvo electric tractors as alternatives. ZET SCALE works by pooling demand from multiple large shippers. That structure gives manufacturers a single large order book and gives participating fleets better pricing. PepsiCo and Microsoft are among the shippers receiving vehicles. Initial deployments are planned around major freight hubs, including California, Texas, the Pacific Northwest, Chicago, Atlanta, and the New York–New Jersey area.
The strategy matters because Class 8 electric trucks are expensive to manufacture at low volume. By aggregating orders, the alliance tries to move electric trucks closer to diesel price parity. The scale also reduces supply-chain uncertainty, which has been a barrier for fleets considering a technology switch.
FedEx placed a 2,000-unit order with Harbinger for medium-duty electric delivery trucks. Harbinger, a startup focused on commercial EVs, is expected to deliver the trucks by the end of 2027. FedEx already has 53 Harbinger vehicles on the road and previously participated in a $160 million funding round for the company.
Medium-duty delivery vehicles are considered a strong fit for electrification. Their routes are often fixed, daily mileage is relatively predictable, and the vehicles return to a central depot where charging infrastructure can be installed. FedEx’s order signals that parcel carriers are moving beyond pilots and into volume procurement.
Tesla’s mass-produced Semi continues to gain commercial traction. In September, two notable deployment plans were announced:
Google’s Texas corridor: Google is working with Nevoya and the Center for Green Market Activation to deploy 25 Tesla Semis and the charging infrastructure needed along a Houston–Dallas corridor. The same program aims to add 38 additional trucks through other participating companies.
IMC Logistics in California: IMC plans to add 50 Tesla Semis to its California fleet. The mix includes standard models with up to 325 miles of range and long-range versions rated up to 500 miles. IMC will use the trucks for drayage around Southern California ports and for longer hauls into inland markets.
The IMC order highlights how one fleet can use different battery configurations to match duty cycles. Short-haul drayage does not require maximum range, while regional runs benefit from the 500-mile option. A flexible fleet plan reduces upfront cost and keeps trucks busy on the routes where electric operation makes the most sense.
The volume announced in September is a turning point for the U.S. freight market. A single 2,500-truck order effectively doubles the existing Class 8 electric fleet, which removes a major risk for other buyers. Fleet managers tend to follow proven deployments; larger fleets create more service data, charging experience, and maintenance knowledge.
It also signals that the commercial model is shifting. Buyers are no longer purchasing electric trucks one or two at a time. They are placing orders in the hundreds and thousands. That change puts pressure on truck makers to deliver at scale and on charging providers to build infrastructure where trucks actually run.
Public-health and climate benefits remain central to the case. Diesel trucks emit nitrogen oxides and particulate matter, both of which contribute to asthma, heart disease, and other respiratory illnesses. Electric trucks produce no tailpipe emissions, so neighborhoods near ports, warehouses, and highway corridors stand to gain the most from this transition.
The September 2026 announcements did not happen in a vacuum. State and federal policies continue to push the freight sector toward zero-emission equipment. California’s Advanced Clean Fleets rule, along with federal grant programs, has made electric trucks more cost-competitive than they were a few years ago. At the same time, falling battery costs and improvements in charging technology are addressing range and downtime concerns.
The ZET SCALE model adds another layer: demand aggregation. By aligning buyers around a common specification and order timeline, it creates a business case that individual fleets cannot achieve alone. Similar purchasing collaborations have been used in other sectors, and the logistics industry is starting to apply them to vehicle procurement.
EDF’s Electric Fleet Deployment & Commitment List will continue to track all announced orders and deployments. October announcements will show whether the September surge was a peak or the beginning of a sustained pattern. Fleet operators should watch three things: delivery timelines, charging infrastructure installation milestones, and changes in vehicle pricing as order volumes grow.
For now, September 2026 stands as the clearest signal yet that medium- and heavy-duty electric trucks have entered the commercial mainstream. The orders are large, the buyers are household names, and the vehicles are already scheduled for production and delivery. The next few months will determine whether the momentum continues.
