ABF Freight announces the purchase of two Class 8 Tesla Semi electric trucks.

The new equipment will primarily support linehaul operations within California, with planned extension into Reno, Nevada, and potentially other locations. Compared with the 2025 pilot, which focused mainly on the Reno–Sacramento corridor, this deployment significantly expands lane coverage to evaluate performance across a broader segment of the ABF network.

"Our 2025 pilot gave us valuable insight into how electric Class 8 equipment can perform in real-world LTL operations," said Matt Godfrey, ABF Freight president. "Adding Tesla Semis to our lineup allows us to expand that across more lanes and operating conditions to evaluate whether heavy-duty electric vehicles meet the same standards for safety, reliability and performance across our existing fleet."

While the 2025 pilot demonstrated strong early results, ABF will continue evaluating the Tesla Semi over a longer period and broader operating footprint before making additional investment decisions. The company plans to benchmark the electric trucks against its diesel fleet using the same disciplined approach to total cost of ownership, operational efficiency, safety and employee experience that guides fleet investments across the business.

During the 2025 pilot, the Tesla Semi achieved an average energy efficiency of approximately 1.55 kWh per mile, a strong result for Class 8 operations. With deployment expanding across additional lanes and driver groups, ABF expects to gain deeper insight into everyday performance across its network. While the company expects performance to remain consistent with the pilot, the broader operating profile will allow for a more comprehensive evaluation.

Driver feedback from the pilot was positive. Operators highlighted strong visibility, comfort and overall performance, including reliable operation on demanding routes such as the 7,200-foot climb over Donner Pass. Initial feedback during orientation on the new units has also been encouraging, with drivers noting the combination of comfort and ease of operation while maintaining the capability expected of a Class 8 tractor in a demanding LTL environment.
