At ACT Expo 2025, fleets emphasized practical and tested solutions for decarbonization, including battery-electric, hydrogen, and renewable diesel powertrains. Discussions at the expo highlighted the 'Run on Less: Messy Middle' initiative, focusing on long-haul decarbonization. Fleets shared insights on the use of alternative fuels like hydrogen and the importance of generating real-world data on their effectiveness. Blue Bird and Harbinger introduced innovative medium-duty solutions for Class 5-6 fleets. Blue Bird unveiled a propane-powered strip chassis and an all-electric step van, while Harbinger presented a plug-in hybrid system with a 500-mile range, including a gas-powered range extender and electric drive. The expo also highlighted advancements in aftertreatment systems to meet upcoming NOx emissions regulations. Manufacturers like Cummins showcased technologies such as electric heaters integrated into exhaust streams to warm components quickly and improve emissions at cold starts. The focus is on enhancing system reliability, uptime, and compliance while simplifying system architecture. In the realm of autonomous trucking, Plus made significant progress with its SuperDrive system, completing tests successfully without a driver onboard. The system, which includes autonomous fallback safety features, is undergoing public road trials in the U.S. and Sweden. Partnerships with OEMs, including Hyundai, are accelerating the commercial launch of the system, particularly for hydrogen truck applications. The expo showcased a convergence of innovative solutions driving decarbonization efforts across the fleet management industry, emphasizing the importance of practical and tested approaches to meet sustainability goals.
