The S 130 and S 150 models are introduced with optional air suspension, which becomes a standard feature in 1969, giving passengers an even smoother ride. Yet another comfort enhancement Setra introduces are the standard anti-fog, double glazed side windows. In terms of safety, Setra also makes major strides with a state-of-the-art braking system with hydro-pneumatic dual-circuit brakes, which can be applied with exceptional sensitivity, thanks to their compressed air running plate brake valve.
The S 80 dominates at the smaller end of the range, driving out the S 100. And the flagship of many bus fleets, the S 150, enjoys outstanding turnover, with 2,479 units sold. The entire 100 series, with its 22 models, sells an impressive 12,339 units – the company’s greatest success to date.
