34th Aachen Colloquium Sustainable Mobility
Advanced robotics, electric drive platform, solid-state battery technology
Summary
From October 6 to 8, 2025, the 34th Aachen Colloquium Sustainable Mobility, being organized by the Aachen Kolloquium Fahrzeug- und Motorentechnik GbR, took place at Eurogress Aachen.
Around 600 experts from academia and industry gathered to discuss the latest developments and trends in sustainable mobility. The event was a strong demonstration of the industry’s commitment to advancing solutions, especially in challenging times. Efficiency, safety, and environmental compatibility were once again central themes in this international exchange.
The colloquium provided an inspiring platform for professional dialogue and the joint development of innovative ideas. Participants experienced a diverse program featuring around 80 technical presentations that showcased recent research findings and developments. Topics included battery technologies, hydrogen applications, electric and hybrid powertrains, range-extender vehicles, synthetic fuels, innovative vehicle dynamics control systems, and the development and validation of advanced driver assistance systems and automated driving functions.
In addition to the lecture program, visitors had the opportunity to experience the latest vehicle and powertrain concepts firsthand during the popular driving event in front of the Eurogress. A range of current production and concept vehicles were available for test drives, including:
- BEE – BEV Goes eHighway: large-scale production BEV truck with a pantograph system
- BMW 740d with Level 3 autonomous driving
- eD1
- FEV Xpeng G9
- Lotus Emeya R
- NIO EL8
- Porsche Taycan Turbo GT
- Renault 5
- Suzuki Swift Hydrogen DI
- Tesla Model 3 equipped with Tula Dynamic Motor Drive technology to improve eDrive efficiency by pulsing torque near peak efficiency leading to reduced energy consumption.
- Volvo XC60 equipped with dual tank setup (HVO and Diesel). The fuel supply to the engine was changed during the demo drive and detected by the DENSO Fuel Detection Logic.
The main program began on October 7 with a plenary session featuring keynote speeches from Emilio Scervo (Bugatti Rimac), Dr. Nikolai Ardey (VW AG), and Prof. Lutz Eckstein (VDI), offering strategic insights into the future of mobility.
A spotlight was placed on automotive start-ups through engaging sessions such as Turbo Talks and a dedicated plenary discussion. The conversation delved into the unique challenges and emerging opportunities within Germany’s automotive sector, offering insights into innovation, investment trends, and the evolving landscape for new ventures.
The final plenary session addressed the sustainable future of off-highway industrial applications. Speakers from CNH, Kässbohrer, and Claas discussed propulsion technologies such as battery-electric, hydrogen, and synthetic fuels, emphasizing the need for industry-regulator collaboration.
The technical exhibition featured around 25 companies and start-ups showcasing their innovations. Universities contributed nine poster presentations from young researchers.
The full agenda of lectures can be viewed in the official program booklet.
The proceedings are filling two books and can be ordered - also for previous colloquia - through the Aachen Colloquium homepage.
Next year the event will be held from October 5th to 7th, 2026.
At the Aachen Colloquium, the automotive engineering providers FEV and fka, play significant roles as key contributors and exhibitors, showcasing their latest innovations in sustainable mobility and automotive technology. Let’s have a closer look at the technologies exposed at their booths.
