ArcBest Pilots Tesla Semi in Over-the-Road Operations, Achieving 1.55 kWh/mile Efficiency.

ArcBest successfully completes a pilot program of a Class 8 electric semi-truck in real-world operations. The Tesla Semi logged 4,494 miles with an energy efficiency of 1.55 kWh per mile. ArcBest is committed to integrating emerging technologies that enhance operational efficiency and environmental responsibility, but continued infrastructure development is necessary for broader deployment of EV semis.

Logistics giant ArcBest (NASDAQ: ARCB) has successfully completed a three-week pilot program evaluating a Tesla Semi electric truck in real-world operations. The pilot, conducted through ArcBest's less-than-truckload carrier ABF Freight, showcases the company's commitment to integrating emerging technologies that enhance operational efficiency and environmental responsibility.

The Tesla Semi, operated across typical dispatch lanes between Reno, Nevada and Sacramento, California, logged 4,494 miles over the three-week period. This included over-the-road routes, regional runs, and rail shuttle operations. The electric truck achieved an impressive energy efficiency of 1.55 kWh per mile, averaging 321 miles per day. This performance matches or exceeds the efficiency of diesel trucks, indicating strong potential for long-haul transportation [1][2][3][4].

Driver feedback was overwhelmingly positive, with operators praising the vehicle's comfort, safety, and intuitive controls. Features such as the center seat configuration and wide visibility were highlighted as key advantages. The pilot program also demonstrated the need for continued development of charging infrastructure to support broader deployment of electric vehicles (EVs) across longer routes [1][2][3][4].

ArcBest currently operates nine electric yard tractors, two electric forklifts, and two Class 6 electric straight trucks. The company plans to continue assessing the long-term viability of Class 8 EVs within its fleet, focusing on leveraging innovation to improve efficiency, reduce emissions, and deliver sustainable logistics solutions [1][3].
