No, the acquisition price for the Setra S 6 1955 was not favourable, but somehow seemed the bus companies to have taken him into their hearts. It was anything but compatible with larger models. The drove around still with front engine and truck chassis to a large extent. That was hardly possible for the S6, because too much overhang front would have faced a too small utility space. So, rearwards with the engine. By this means and by its enormous space requirement during spring deflexion, the rigid axle became impossible rear and the front also.

So it came down to a kind of passenger car chassis, incorrectly called 'swing axles' by the manufacturer. But, e.g. Daimler-Benz has designated therewith floating axles. However, the used here was a unicycle suspension without the harmful camber changes when rebounding. By the way, it was hereby superior even the rear axle of the 300 SL. Only the coil spring for balancing between both sides of the axle was then taken over again by Daimler floating axles.

For the actual spring system was chosen a rubber spring according to a patent from Switzerland. It is one of the few details that have been revised once more in the course of the nine years. Otherwise, the S6 ran and brought its owners pleasure with about 1.200 km range (with auxiliary tank). Which has so far held, because some of these buses was saved from the scrapheap even for decades. 11/15
