What the evidence shows
Measured deployments show battery-electric trucks hauling freight in regional, drayage, delivery, and depot operations. NACFE's 2025 Class 8 demonstration logged over 73,000 validated revenue miles; its BEV cohort ran 350-500-plus miles on many days and reached an 875-mile maximum on favorable terrain. Route, payload, terrain, and charging access still matter, and participating depot sites took 9-36 months to energize infrastructure.
Older vehicles or current generations?
Evidence spans MY2022 pilot and selected 2023/2025 deployments. It shows specific freight work, not universal capability; old pilot results do not establish MY2026 performance.
We separate vehicles from before 2023 and 2023 onward. A report’s publication date does not establish a vehicle’s model year or a battery’s manufacturing date.

“Not reported” means the source does not disclose it. Model year, first registration, vehicle assembly and battery manufacture are different dates. Unmatched studies cannot establish how much newer batteries improved.
Which brands do these results describe?
Field reports include Tesla, Volvo and Freightliner vehicles, while NACFE’s cohort also names Windrose. These sources demonstrate freight examples for those makers but are not matched tests; they do not support a cross-brand ranking or prove a named truck fits every duty cycle.

Heavy electric trucks are already moving commercial freight
There is direct evidence against the claim that electric heavy trucks cannot perform freight work. NACFE and RMI's Run on Less – Electric DEPOT collected daily telematics from 22 production battery-electric vehicles operating from 10 depots. The vehicles covered Class 2b through Class 8 and came from 11 manufacturers. Its 2024 follow-up concluded that electric vans, trucks, and heavy tractors were operating well in many duty cycles, while naming cost, battery weight, utility timelines, and the need for better charger- and depot-level data as continuing obstacles. The finding describes selected operating fleets, not the whole truck market. [1]
The deployments include mainstream non-Tesla tractors. Daimler reported in April 2024 that Freightliner eCascadias had accumulated more than 6 million customer miles across more than 50 U.S. fleets. Volvo reported in April 2025 that VNR Electric trucks had reached 15 million customer miles in North America, with over 700 trucks operating across the United States and Canada. Those totals show trucks in real customer service; they do not prove equivalent cost, utilization, or uptime against diesel tractors. [3] [4]
The right route matters more than a headline range
The regional Class 8 models discussed here are built around shorter return-to-depot work. Freightliner lists eCascadia typical ranges of 249.4 km to 370.1 km by configuration, based on more than one million miles of its own operational experience; it cautions that load, conditions, driving, and axle choice change range. Volvo lists its VNR Electric at up to 442.6 km, while describing 354.1 km as typical for the six-battery 565 kWh configuration. These ranges can cover many port drayage, local distribution, and regional routes, especially when trucks return to a known depot. They are not a promise of 442.6 km under every load or temperature, and they do not describe every Class 8 truck configuration. [5] [6]
NACFE's 2025 Messy Middle demonstration extends the observed range evidence into selected long-haul work. Its September run tracked 14 Class 8 tractors across 13 fleets for more than 73,000 validated revenue miles. The 2026 operations report says battery-electric trucks with 565 to 705-plus kWh packs achieved 350 to 500-plus miles per day; the BEV cohort's one-day maximum was 1,408.2 km on favorable terrain. NACFE found that BEV efficiency varied 50% to 70% between comparable flat and mountainous routes. The distance maximum is one selected-cohort observation, not an expected daily route or a guarantee for a particular model. [11]
Long-haul operation adds charging and payload constraints
The ICCT's Class 8 model makes those limits concrete. It sizes a high-roof sleeper for 804.7 km per day, assumes charging at breaks, and caps the battery at 1 MWh because of payload and volume constraints. In its 2022 case, the assumed 350 kW charging system and one-hour break produced a 1 MWh pack with a modeled design point of about 478 km. For 2030, the study assumed 1 MW charging and an 840 kWh pack for a 300-mile design point. The model therefore depends on a functioning high-power corridor network and planned stops; a truck needing more range may require extra charging time, a larger battery, or a changed route. NACFE also found that batteries affect payload, although it cautioned that diesel trucks do not always operate at maximum gross weight. [8]
Depot power is part of the duty cycle too. NACFE reported that small urban depots needed less energy and infrastructure, while large depots were beginning to scale; one early report cited daily routes of 22.5 km to 67.6 km for parcel fleets and a depot using 0.9 MWh per day. In its 2024 follow-up, NACFE reported that the 10 participating North American depots had 139 chargers and used 1,044 MWh over 719,104.8 km; getting those sites energized took 9 to 36 months. Larger sites planned for several megawatts, and some fleets used portable chargers while permanent service was built. Smart charging can coordinate vehicles with time-of-use and demand-charge tariffs, but software cannot remove a feeder upgrade or a route that exceeds the truck's usable range. The energization interval comes from a small selected sample, and the energy and distance totals combine several vehicle classes. [2] [10] [9]
Public funding and operating support are part of several deployments
Volvo delivered 70 VNR Electric trucks through SWITCH-ON, a Southern California regional freight and drayage program backed by up to $19.5 million from EPA and $2 million from South Coast AQMD for charging infrastructure. This is evidence that public money helped launch the fleet and its chargers; it cannot be divided into a clean per-truck price because the grant also covered charging and project costs. Volvo says its Gold Service Contract includes maintenance, towing, unplanned repairs, and battery coverage, but does not publish a comparable contract price. A fleet's operating case should include available grants and service contracts explicitly, while keeping them separate from unsubsidized truck cost. [7]
Data period: NACFE Run on Less – Electric DEPOT measured operations in September 2023 and reported follow-up analysis in May and July 2024; Volvo and Daimler customer-mile totals published 2024-2025; NACFE Messy Middle measured Class 8 operations September 8-26, 2025 and published operations findings March 15, 2026; current OEM range specifications accessed 2026-10-05; ICCT long-haul duty-cycle model published 2023
What this does—and doesn’t—tell us
- The NACFE Run on Less cohorts were small, selected demonstrations, not random samples of U.S. trucking. The 2026 875-mile result was the BEV cohort's maximum on favorable terrain, not typical output or a result attributable to one specific truck. OEM customer-mile totals are manufacturer-reported and do not supply a comparable diesel control group, uptime denominator, or independent cost audit.
- OEM range figures are configuration-specific estimates. Freightliner says range varies with axle and battery configuration, load, driver behavior, weather, and other conditions; Volvo labels its 275-mile figure as maximum range and gives 354.1 km as a typical range for that configuration.
- The $21.5 million SWITCH-ON figure combined public funding for vehicles and charging infrastructure. It does not reveal a truck's retail price or a per-truck grant amount; participating fleets and service routes were selected for a regional California deployment.
- The ICCT 500-mile long-haul case is a model using assumed charging stops and a maximum 1 MWh battery for payload and volume reasons. It identifies engineering and charging needs, not proof that every U.S. long-haul route can be completed without operational changes.
- The 9-to-36-month charging-energization interval comes from 10 selected North American depots, including one in Canada; it is a real deployment range, not a forecast for every utility or site. The 1,044 MWh and 719,104.8 km aggregate mixed vehicle classes and cannot be read as a Class 8-only efficiency result.
Electric heavy trucks can perform real freight work on matched routes. Evaluate each operation against actual daily mileage, payload, charging windows, utility capacity, and backup plans; fleetwide readiness does not follow from a successful pilot.
