International Conference on Gears 2025

The VDI International Conference on Gears (ICG) is a leading international meeting point for experts from research and industry to present and discuss the latest developments and trends in gear and drivetrain technology. The conference is held every two years, organized by the VDI Wissensforum in cooperation with the Gear Research Centre (FZG) of TUM in Garching. The 11th ICG will take place from September 10-12, 2025. More than 120 contributions will present state-of-the-art research results on gears and drive systems to an audience of over 500 participants.
