Projected heavy-duty truck market size is set to hit $177.2 billion by 2032, but 2023 also shows why the transition is moving slowly. Alternative fuel deployments are still early with hydrogen at just 0.1% of global unit share and battery electric and related sales under 5% together, even as OEMs like Daimler Truck report 4,200-plus BEV deliveries. Meanwhile, the biggest day to day lever for fleets is often operational, from tire pressure monitoring to route optimization that can cut miles driven by 5 to 15%.

Key Takeaways

  • In 2023, sales of alternative fuel heavy-duty trucks in the U.S. increased but remained a small share of total heavy-duty truck sales, with EV and hydrogen deployments still in early commercialization.
  • In 2023, Daimler Truck delivered 4,200+ battery-electric trucks (FUSO eCanter and Mercedes-Benz eActros and other BEV deliveries included in company reporting), signaling increased OEM BEV rollout.
