From May 19 to 23, 2025, the CIMAC Congress takes place in Zurich, Switzerland, marking the 31st edition of this renowned global event since the founding of the association in 1951. As always, the Congress serves as a key platform for technical exchange, strategic dialogue, and collaboration across the entire large engine industry — bringing together experts from around the world to address the most urgent challenges and explore the latest innovations.
Zurich, known for its engineering excellence, innovative spirit, and high quality of life, offers the perfect setting for this gathering. Situated in the heart of Europe and home to leading research institutions, technology companies, and industrial players, the city stands for precision, sustainability, and forward-looking thinking — all core values of the CIMAC community.
The 2025 Congress takes place at a time of profound transformation. The internal combustion engine industry, both on the marine and the power generation side, is undergoing significant change. A central focus lies on realistic, scalable approaches to decarbonization, the adoption and integration of alternative fuels, and the fulfillment of increasingly ambitious climate and regulatory targets. Digitalization continues to reshape system design, operation, and maintenance, while non-shaftline propulsion systems and hybrid energy architectures are gaining importance in the search for flexible and future-proof solutions.
The technical program reflects this broad spectrum of topics. Presentations, poster sessions, and interactive formats such as Pecha Kucha highlight the latest scientific research, product developments, and field applications. The accompanying exhibition showcases innovations from across the global value chain, and the traditional technical tour offers insights into real-world implementations. Keynote sessions and panel discussions challenge participants to think beyond current boundaries and foster dialogue across disciplines and sectors.
The CIMAC Congress 2025 stands as a vivid expression of the industry's commitment to progress — a space where challenges are addressed collectively, and solutions are developed through cooperation, knowledge sharing, and open exchange.
