BumbleB autonomous EV shuttle starts Stuttgart campus trials

A self-driving electric shuttle called BumbleB, developed by German engineering company Bertrandt, has entered live trials at the Fraunhofer campus in Stuttgart. The project is led by Fraunhofer and focuses on reimagining how companies and institutions can handle short-distance employee mobility in a more sustainable way.

The BumbleB shuttle will operate a fixed route connecting the research campus to a nearby S-Bahn commuter rail station, serving as a last-mile link for employees and visitors. This type of campus-to-transit connection is increasingly seen as a practical entry point for deploying autonomous electric vehicles in controlled environments.

The Stuttgart trial is part of a broader European push to develop and validate autonomous mobility solutions in real urban and semi-urban settings. Germany, with its strong automotive industry heritage and active research infrastructure, is well positioned to lead such pilot programs.

If successful, projects like BumbleB could provide a scalable blueprint for autonomous electric shuttles at corporate parks, hospitals, universities, and other campuses across the EU — complementing public transit rather than replacing it.
