Fleet buys Tesla Semi electric trucks after stunning 1.55 kWh/mile efficiency

ArcBest (ARCB), the multibillion-dollar logistics company, is purchasing two Tesla Semi electric trucks for its ABF Freight fleet after a successful 2025 pilot program that averaged 1.55 kWh per mile over 4,494 miles. The purchase marks a significant step beyond piloting and into actual fleet investment for the less-than-truckload (LTL) carrier, which is now expanding its electric Class 8 testing across a broader operating footprint.
