Europe’s transition towards a circular green economy is accelerating, highlighted by the urgent need for sustainable alternatives to fossil fuels. While conventional electric vehicles present a viable solution, their manufacturing heavily relies on critical raw materials. The Zephyr AGH project addresses this environmental challenge by developing an innovative, lightweight hybrid vehicle designed to minimize both energy consumption and material dependency. The powertrain architecture utilizes an electric motor a...

Zephyr AGH represents an attempt to address the need for low-emission transportation. In its initial iteration, it was a race vehicle powered by compressed air. Currently, the project is being developed with a focus on maximizing its utility, particularly in urban traffic conditions. Due to the low energy density of compressed air, it is not a sufficient standalone energy carrier for individual transportation. To maintain the low-emission profile of the vehicle, the design team decided to integrate electric motors...
