At ACT Expo 2025, the message underscored was that achieving zero emissions is a gradual process, akin to a relay race rather than a sprint, with internal combustion engines (ICE) still playing an important role. This was particularly relevant for heavy-duty truck managers who are formulating decarbonization strategies aimed at emission reduction while ensuring operational uptime and profitability. Mathias Carlbaum, the International President and CEO, highlighted that ICE trucks, especially those utilizing biodiesel or renewable fuels, continue to be crucial for short-term decarbonization efforts.
“Decarbonization is a journey that cannot be achieved in just one or two years,” Carlbaum stated. “Some programs may see temporary pauses, but our medium and long-term objectives remain steadfast.”
EV Rollouts: Early Lessons and Smart Planning
Carlbaum noted the eMV, the company’s medium-duty battery-electric model, as a significant learning experience before the rollout of their latest electric regional haul tractor, the eRH. Despite the low volume of the eMV, the real advantage lay in the lessons learned, including infrastructure development, fleet coordination, and a complete overhaul of operational planning.
He remarked, “It’s not as straightforward as just replacing a diesel vehicle with an electric one; it impacts routing and operational planning.” The company has focused on preventing common initial missteps for customers transitioning to electric vehicles.
Transitioning to electric involves more than merely changing powertrains; it requires adaptations in routing, depot designs, charging schedules, and driver training. Delays may also occur due to regulatory permissions and grid limitations. For fleets that aren’t ready for complete electrification, Carlbaum emphasized the need for alternative technologies to step in.
Efficiency Gains from Modern ICEs
This is where the S13 integrated powertrain becomes relevant. Launched to positive market feedback, this diesel platform is tailored for decarbonization and approved for biodiesel use, delivering impactful results. Carlbaum shared that the system has exceeded initial performance expectations, yielding both economic and ecological benefits.
He acknowledged the varying stages of customers’ decarbonization journeys, where some are investing in full EV infrastructure while others seek immediate emission reductions without significant capital investments. “What can I do to enhance efficiency without substantial capital outlay? Our other solutions, which could include gas or the S13, can support this improvement,” he stated.
Avoiding Speculation, Embracing Strategy
Carlbaum cautioned against decision-making based on speculation, particularly in light of market volatility and shifting regulations. He urged that it’s vital to rely on data and collaborate with partners who can offer adaptable solutions. “Avoid speculation and theoretical approaches,” he advised. “Address uncertainties using the best available information.”
Staying close to clients and developing plans that meet today’s requirements while preparing for future advancements remains paramount, according to him.
Autonomous, Digital, and Practical Solutions
Carlbaum also highlighted advancements in software, digital tools, and autonomous systems, which are progressing rapidly and could provide immediate improvements in efficiency and cost reduction, even more so than zero-emission technologies. “How can technology enhance our efficiency while reducing costs right now?” he questioned, emphasizing this as a focal point.
