ArcBest Purchases Two Tesla Semis After 2025 Pilot: Efficiency Data Drives Decision
ABF Freight
ABF Freight, a division of the LTL freight transport group ArcBest, has formalized the purchase of two electric Tesla Semi trucks to integrate into its operational fleet. The decision comes about a year after the conclusion of a pilot program conducted in 2025, the results of which evidently met the company’s internal criteria for justifying a more structured investment.
The 2025 Pilot Project: What Was Tested
The pilot program involved a single Tesla Semi used for three weeks on real commercial routes in the Reno-Sacramento corridor, extending to regional operations in the California Bay Area and shuttle services. During that period, the vehicle covered a total of 4,494 miles, with a daily average of 321 miles (516 km)—values consistent with typical usage in medium-range LTL transport.
The most significant data that emerged from the test pertains to energy efficiency: the Semi registered an average consumption of 1.55 kWh per mile. To contextualize this figure, it is useful to compare it with results obtained by other operators who conducted similar tests:
- Tesla (production vehicle presentation, 2022): 1.7 kWh/mile claimed by Elon Musk
- DHL (operational tests): 1.72 kWh/mile
- Saia (operational tests): 1.73 kWh/mile
- ABF Freight (2025 pilot): 1.55 kWh/mile
ArcBest's result ranks about 9% below the values recorded by other operators, a not insignificant margin at a fleet scale. The variables that may have contributed to this data include the topographical profile of the routes (the Sierra Nevada-Pacific Coast corridor has significant elevation changes that promote energy recovery during braking), load patterns, and speed management by drivers.
From Analysis to Purchase
ABF Freight did not treat the pilot as a communication exercise, but as a data collection phase functional to an investment decision. The two Semis purchased will primarily operate on long-range Californian routes, with a planned extension towards Reno and potentially other destinations, expanding their operational range beyond the initial corridor.
Matt Godfrey, President of ABF Freight, framed the purchase in operational terms: the goal is to verify whether heavy electric vehicles hold up against the existing diesel fleet based on concrete parameters, total cost of ownership (TCO), operational efficiency, safety, and driver experience. This is therefore not a declaration of intent towards decarbonization but rather a technical-economic evaluation under real conditions and on a larger scale.
The Evaluation Method
The approach adopted by ArcBest is what industry analysts consider the most robust for electrifying commercial fleets: using the same KPIs applied to thermal vehicles, without parallel metrics or lighter criteria for electric vehicles. The direct comparison on TCO, reliability, and driver satisfaction will provide more useful—and more defensible internally—data than any theoretical benchmark. The fact that a large LTL operator like ArcBest is proceeding in this direction methodically, rather than with premature announcements, is likely the most significant signal emerging from this story.
