Truck & Off-highway Engineering - October 2025

Overview

The October 2025 issue of Truck & Off-Highway Engineering presents a comprehensive overview of the latest advancements and discussions in the commercial vehicle and off-highway equipment sectors. This edition highlights key themes such as the integration of technology, the importance of data management, and the evolving landscape of electrification and software-defined vehicles (SDVs).

Key Highlights:

1. Workforce and Technology Integration: The issue opens with insights from industry experts at a recent engineering conference, emphasizing the critical role of engineers in leveraging data. Vincent Pesch, an engineering director, draws parallels between data management and waste heat recovery in internal combustion engines, suggesting that organized data can become a valuable commodity for enterprises. This highlights the ongoing need for skilled professionals who can reconcile and monitor data effectively.

2. Software-Defined Vehicles (SDVs): Roopak Ingole from Cummins discusses the necessity of software-defined powertrains to unlock the full potential of SDVs. He argues that these powertrains should not only provide propulsion but also serve as platforms for intelligence, enhancing energy management, safety, and customer features. This shift towards software integration signifies a move away from traditional mechanical systems, indicating a future where vehicles are more adaptable and intelligent.

3. Over-the-Air (OTA) Updates: The issue addresses the frequency of OTA updates, with insights from Florian Rohde, a former Tesla firmware system validation manager. He notes that while early adopters may tolerate updates every six weeks, standard users prefer quarterly updates. This finding underscores the importance of user experience in software deployment, as excessive updates can lead to "update fatigue" and dissatisfaction among consumers.

4. AI and Cybersecurity Concerns: Bodo Seifert, a senior automotive functional safety engineer, raises alarms about the potential risks associated with AI in vehicle systems. He discusses the threat of poisoning attacks, where malicious actors manipulate training data to compromise safety features, such as adaptive cruise control. This highlights the critical need for robust cybersecurity measures as vehicles become increasingly reliant on AI technologies.

5. Electrification in Off-Highway Applications: Kent Wanner from John Deere provides insights into the challenges and opportunities of electrification in off-highway equipment. He acknowledges that while electrification is gaining traction, it faces competition from established technologies. Wanner emphasizes the role of hybrids in various applications, suggesting that a one-size-fits-all approach may not be feasible. Instead, a mix of battery electric, diesel electric, and hybrid solutions will likely dominate the market.

6. Grease Innovation for Heavy Equipment: The issue also delves into the critical role of lubricants, particularly grease, in ensuring the reliability of heavy equipment. As machines operate in demanding environments, the performance of lubricants becomes paramount. The article discusses how innovations in grease formulations are adapting to meet the evolving demands of the commercial and off-highway sectors, ensuring that equipment can withstand rigorous conditions.

7. SAE International Sections and Collegiate Chapters: The magazine highlights the importance of local SAE International Sections and Collegiate Chapters in fostering community and professional development among members. These groups provide opportunities for networking, skill development, and collaboration, emphasizing the value of engagement in the engineering community.

8. Editorial Insights: The editorial section, led by Editor-in-Chief Ryan Gehm, reflects on the ongoing evolution of the industry and the importance of staying informed about technological advancements. The editorial underscores the magazine's commitment to providing valuable insights and coverage of key topics affecting the truck and off-highway engineering sectors.

In conclusion, the October 2025 issue of Truck & Off-Highway Engineering serves as a vital resource for industry professionals, offering a blend of technical insights, expert opinions, and discussions on the future of vehicle technology. As the industry navigates the complexities of electrification, data management, and software integration, this issue provides a timely overview of the challenges and opportunities that lie ahead. The emphasis on collaboration, innovation, and continuous learning reflects the dynamic nature of the engineering landscape, making this edition a must-read for anyone involved in the field.
