The real-world case of Tesla’s electric truck at the logistics company ArcBest.
The electrification of heavy-duty transportation continues to advance, and Tesla has received a new vote of confidence from one of the largest logistics companies in the United States.
ArcBest, a group specializing in freight transportation and distribution with a multibillion-dollar revenue, has confirmed the purchase of two Tesla Semi units for its ABF Freight division. This decision follows the completion of a pilot program in 2025, which yielded remarkable results in terms of energy efficiency and operational performance.
The company believes the data obtained justifies expanding the testing and beginning to integrate electric trucks into actual long-haul transport operations.
Efficiency that is surprising the industry.
The main factor that convinced ArcBest was the data collected during the tests.
Over a three-week period, one of the Tesla Semi trucks traveled 4,494 miles (more than 7,200 kilometers) on commercial routes between Nevada and California, including regional trips and routine logistics operations.
During that period, the truck recorded an average energy consumption of 1.55 kWh per mile (equivalent to 0.962 kWh per kilometer), positioning it as a high-performance vehicle in its class.
This figure exceeds the numbers previously reported by other operators. When unveiling the production version of the Semi, Elon Musk cited an efficiency of 1.7 kWh per mile. Well-known companies such as DHL and Saia have subsequently achieved figures close to 1.72 and 1.73 kWh per mile, respectively.
ArcBest has achieved a significant reduction in its energy consumption, with an approximate 9% decrease compared to established standards.
The new Tesla Semis will operate in California.
The two new units acquired by ArcBest will be used primarily for freight routes within the state of California.
The company also plans to gradually expand its operations to Reno, Nevada, and explore other logistics corridors where electric trucks can demonstrate their viability.
The purpose of this analysis is to make a direct comparison between the performance of the Tesla Semis and the diesel vehicles currently in the fleet.
To this end, the company will conduct a comprehensive analysis of various factors, including total cost of ownership, operational efficiency, reliability, safety, and the drivers’ experience.
The project has the support of the drivers.
In addition to the quantitative results, the drivers’ experience has emerged as a notable aspect of the pilot program.
According to ArcBest, the drivers who participated in the tests highlighted the driving comfort, visibility from the cab, and the vehicle’s overall performance.
One of the highlights was the truck’s performance during the climb up Donner Pass, a challenging mountain route located at an altitude of more than 2,100 meters.
Other logistics operators who have tested the Tesla Semi on some of the most demanding roads in the United States have reported similar experiences.
Tesla has made the strategic decision to increase production of its electric truck.
The acquisition of ArcBest comes at a crucial moment for the Tesla Semi program.
The company has recently begun mass production of this model at its new facility, the Gigafactory Nevada, and has already received significant orders.
Notably, WattEV has placed an order for 370 units, considered one of the largest deployments of electric trucks in California. Other companies, such as DHL, CEVA Logistics, and several port operators, have implemented additional testing and procurement programs.
The current challenge lies in producing a sufficient number of units.
The industry’s growing interest confirms that electric trucks are moving beyond experimental projects to become real-world work tools.
Indeed, the advantages in energy costs—especially given the volatility of diesel prices—are driving their adoption among major logistics operators.
However, the real challenge for Tesla will be to ramp up production and meet demand that appears to be growing at a rapid pace.
If the company manages to maintain the levels of efficiency it has demonstrated in real-world operations, the Tesla Semi has the potential to become a key player in the transformation of freight transportation over the next decade.
