The S6 was as innovative in the bus industry of the 50’s as an independently driving electrical car is today.
Sci-Fi authors weren't impressed because they had seen the S6 driving on other planets and working people didn't want to ride it because the UFOs got access to their thoughts right through the class roof.
Self-conscious beautiful people ride in it because the same way the passengers looked out from the bus, everyone could see in. A ride in that bus was as comfortable as riding in a VW beetle.
The S6 can manoeuvre in any smaller or larger settlement without causing the driver's shirt to tear or him cursing in German.
Setra S6 is the first bus produced in a series that was built with unibody construction.
That means that before the bus body was fixed on a truck chassis but now the entire body and chassis are welded together and all the necessary details and junctions were fixed on it. For the first time the engine was located at the back which made maintenance easier and also allowed isolating the engine noise from the saloon. After the Setra S6 appeared on the roads many other buses transformed and became similar to the Setra.
