The upBUS system is being developed by the Institute of Structural Mechanics and Lightweight Design (SLA), the Chair of High Frequency Electronics (HFE), and the Chair of Production Engineering of E-Mobility Components (PEM). It is based on a detachable passenger compartment that can automatically couple either to a road vehicle chassis or to a cable car suspension. The overall concept and its intended role in urban transport have been previously outlined in the upBUS project article published by Sustainable Bus.
