Auto Tram Extra Grand

 Auto Tram Extra Grand is developed by the Fraunhofer Institute for traffic and Infrastructure Systems.  Considered as the longest bus in the world, it is nearly 31 meters long, has four steering axles and can carry 256 passengers.  Combining the capacity of a small train with the maneuverability of a bus, the vehicle runs mostly on electric power.
