The 37th SIA Powertrain Congress 2025 is a key event in the automotive industry, bringing together engineers, innovators and thought leaders to shape the future of sustainable and advanced mobility. With challenges facing the powertrain industry such as reducing greenhouse gas emissions, controlling costs, expanding infrastructure and securing the supply of critical materials, this congress provides a platform to address these issues amidst a complex geopolitical and regulatory landscape. We look forward to seeing you in Port Marly for our presentations or at our stand.

IAV is shaping the future of mobility with the best minds: experienced engineers develop software-defined vehicles and outstanding powertrains. We use state-of-the-art technologies to create solutions for the mobility of tomorrow. Automotive intelligence is the integration of advanced technologies and intelligent systems into vehicles to improve their performance, safety and user experience. This includes the use of data analysis, artificial intelligence and connected systems to make vehicles more efficient and autonomous.

Panel discussion at the opening

Panelist: Thomas Müller
Abstract: The panel discussion will address the challenges and opportunities of the transition to 100% electric vehicle sales by 2035 in Europe. Moderated by Stephen Marvin or Nicolas Le-Bigot from PFA, the session will include industry leaders such as Philippe Brune from Ampere, Olivier Lescheira from Stellantis, Thomas Müller from IAV and a consultant from Cway. IAV was selected for its extensive collaboration with the automotive industry, working with different markets and providing solutions for all types of vehicles and powertrains. Discussions will cover new car buyer behavior in Europe, technologies for 2025, BEV purchase challenges, technical options, market risks, EE-EV alternatives and government support for BEVs through incentives and regulations. Energy and technology independence will also be discussed.

BEV to REEV: A Scalable Powertrain Platform Concept

Speaker: Dr Alexander Fandakov
Abstract: This study addresses key challenges in electric vehicle adoption (high costs and range anxiety) by proposing a serial hybrid powertrain as a practical and scalable solution. Built on a modern BEV platform, the concept involves resizing the battery and integrating a compact, cost-effective range extender (REx) engine optimized for performance, noise reduction, and compatibility with renewable or CO₂-neutral fuels. The architecture improves overall cost-efficiency, lifespan, and thermal management through component optimization and shared systems. This flexible platform supports both pure BEVs and range-extended variants, aiming to enhance customer appeal while accelerating the transition to cleaner transportation and helping OEMs meet regulatory targets.

Integrated electronics for electric vehicles: progress in efficiency, scalability and sustainability

Speaker: Dr. Alexander Hoffmann 
Abstract: IAV's study focuses on integrating multiple electronic components into a single system for electric vehicles to optimize space, reduce costs and increase efficiency. The N-in-1 concept combines 8 to 9 key components, such as the traction inverter and the power distribution unit, in an innovative housing design for easy access and assembly. This integration reduces connectors and cables, resulting in cost savings and improved synergies, while unified control electronics simplify maintenance and scalability. The use of standardized software modules also simplifies diagnostics and updating. Overall, the N-in-1 concept is driving affordable and sustainable electric mobility.

Evaluation of sodium ions for low-voltage battery applications

Speaker: Brahim Soltani 
Abstract: The automotive industry is in the process of reducing greenhouse gas emissions, driven by EU regulations and a ban on internal combustion engine vehicles in 2035. Although the development of electric vehicles (EVs) is crucial, recent slowdowns highlight the need for complementary solutions. Sodium-ion batteries (SIBs) are emerging as a promising alternative to lithium-ion batteries (LIBs) for low-voltage applications, as they offer good energy density and better performance at cold temperatures. SIBs simplify thermal management and avoid costly materials that could become cheaper as production increases. IAV is investigating SIB prototypes to find cleaner, sustainable battery options for use in vehicles. Improving low-voltage batteries, such as 12 V on-board batteries and 48 V batteries in mild-hybrid electric vehicles (mHEV), can also help reduce emissions in non-electric vehicles
