  • Stylish equipment for short and long trips
  • Safer than ever with new assistance systems
  • Subtle and effective visual enhancement

It is the most versatile of travel giants: The Setra TopClass S 531 DT double-decker bus covers an enormous range from functional long‑distance buses to individually designed bistro buses. At Busworld Europe 2025, it will take the lead with sophisticated equipment for classic tourist transport, supplemented by pioneering new assistance and safety systems as well as a subtly refreshed look. This is defined, among other things, by the MirrorCam, which is now available as an option to replace the integral mirrors once invented by Setra.

Stylish equipment for short and long trips

Dark-tinted windows and light-alloy wheels on the outside, a step unit behind the driver’s workplace on the inside, a comprehensively equipped kitchenette, and tastefully designed and comfortable seating with 78 passenger seats – this Setra enjoys traveling. A wood‑look floor, the Setra Voyage Plus seats with upholstery in a composition fabric combination in gray and red as well as curtains in gray, and a panoramic roof above the upper deck – all help to create a pleasant atmosphere.

Safer than ever with the latest assistance systems

Passengers also feel particularly safe on board the powerful coach. A host of new safety and assistance systems contribute to this: Active Brake Assist 6 emergency braking system, Frontguard Assist, Sideguard Assist 2, which now operates on both sides, and other systems make traveling in buses safer than ever before. At the same time, they support the driver in their responsible work. The driver also benefits from the new Traffic Sign Assist and, especially in the double-decker bus with its impressive dimensions, from the 360° camera system and the new MirrorCam instead of conventional integral mirrors.

Subtle and effective visual enhancement

Attentive observers discover the subtle and effective visual enhancement of the powerful Setra. For example, the brand face with high-gloss black front panel, framed by chrome inserts with the three-dimensionally designed brand lettering, the round brand badge, and bright LED headlamps. Added to this are the three-dimensional character element on the side and the typical Setra tail lights. Together with the warm and striking paint finish in Cosmos Red metallic, this creates an unmistakable appearance – not only due to the sheer size of the Setra.
