"Yutong has rejected allegations from Norway's Ruter that its new electric buses could be remotely accessed, calling the scenario "technically impossible". Speaking to the German newspaper Berliner Zeitung - and reported also by trade agency Electrive - Yutong stated that such remote control is "technically impossible." Reportedly, the company explained that while its vehicles feature data connections for diagnostics and over-the-air software updates, there is no physical connection between the telematics unit (T-Box) and safety-critical systems like steering, propulsion, or braking."
"Yutong clarified that all vehicle data for the EU is stored on Amazon Web Services servers in Frankfurt, used exclusively for maintenance and performance optimisation, and protected by encryption and restricted access protocols. The manufacturer also specified that over-the-air updates are conducted only with the operator's explicit approval and are limited to comfort, interface, and diagnostic functions, without affecting vehicle control systems."
"Certain remote features, such as preconditioning cabin temperature, are managed entirely by local operators, with no direct access from Yutong. In late October, Norwegian public transport operator Ruter had shared the results of a cybersecurity test of electric buses, conducted in an isolated mountain environment. The trials, involving a new Yutong bus from China and a three-year-old VDL bus, identified potential risks linked to Over-The-Air software updates in modern buses."
Yutong rejects claims that its electric buses can be remotely accessed and says remote control is technically impossible. The company states telematics (T-Box) connections exist for diagnostics and OTA updates but are not physically linked to steering, propulsion, or braking. Vehicle data for the EU are stored on AWS servers in Frankfurt, encrypted and access-restricted for maintenance and performance optimisation. OTA updates occur only with operator approval and are limited to non-safety functions. Local operators manage certain remote features. Ruter's tests identified OTA-related risks, prompting fleet security measures and coordination with authorities, attributed to technological changes rather than product origin.
