Its capacity to transport 123 people and its overall length of 20.03 metres have secured the largest ambulance in the world - a large-capacity emergency ambulance based on the Mercedes-Benz Citaro articulated bus - a place in the Guinness Book of Records.
On Friday, 25 September 2009, an extraordinary record attempt took place in front of the Rhineland-Palatinate State Parliament building in Mainz, Germany. Representatives from the Centre of Ambulance Services of the Government of Dubai, present at the event for the official hand-over of the bus, along with countless onlookers and a large media contingent, were in attendance as the official Guinness Book judges, the Rhineland-Palatinate Interior Minister Karl Peter Bruch and Joachim Mertes, President of the Parliament of Rhineland-Palatinate, measured the precise carrying capacity of the Citaro.
The entry in the Guinness Book of records is registered in the name of the companies that designed, built and equipped the bus: Von Bergh Global Medical Consulting, Gebr. Heymann GmbH, Cytomed Middle East and EvoBus GmbH. Aid workers from the German Red Cross, the St. John’s Ambulance organisation and the ASB, the Worker’s Samaritan Association of Germany simulated a mass casualty event in which numerous accident victims needed to receive medical treatment simultaneously.
