Roll-out ZEDU-1: emissionsfrei unterwegs in die Zukunft ohne Feinstaub und Mikroplastik
Summary
TLDRThe 'Project Zero-Emission 3 Unit, Generation One' focuses on developing and demonstrating an electric drive unit with zero emissions, addressing climate change and health issues related to pollutants like CO2, NOx, particulate matter, and microplastics. The project integrates a closed lamella brake within the electric motor, eliminating emissions during braking. Innovative tire topologies aim to reduce tire wear emissions by 70-90%. Rigorous testing on a roll bench and test track ensures the drive unit's functionality, with the goal of reducing emissions significantly and showcasing the potential for future series production and mobility solutions.
