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...
