ABC (Australia) - - CONTENTS -

Se­tra has launched the S 531 DT 78-seat dou­ble-decker bus, which marks the world pre­miere of new ac­tive brake as­sist and side­guard as­sist in the bus and coach seg­ment.

The emer­gency brak­ing sys­tem, Ac­tive Brake As­sist 4 (ABA 4), is be­ing in­tro­duced in the bus and coach sec­tor for the first time ever on board the S 531 DT.

In ad­di­tion to the pre­vi­ously avail­able func­tions – max­i­mum full-stop brak­ing in re­sponse to sta­tion­ary ob­jects and ob­sta­cles mov­ing ahead of the ve­hi­cle – it now also in­cor­po­rates pedes­trian de­tec­tion with au­to­matic brak­ing re­sponse.

An­other world pre­miere in the bus and coach seg­ment is the use of side­guard as­sist on board the new dou­ble decker.

This em­ploys radar sen­sors to mon­i­tor the lane to the right of the bus along the ve­hi­cle’s en­tire length.

When turn­ing off and cor­ner­ing, it warns the driver of pedes­tri­ans, cy­clists and sta­tion­ary ob­sta­cles in the turn­ing path.

Out­side of built-up ar­eas, it ad­di­tion­ally serves as a lane-chang­ing as­sis­tant. Aero­dy­nam­ics pro­vide the ba­sis for record-break­ing fuel con­sump­tion, which drops by around 7 to 10 per cent com­pared to the pre­de­ces­sor model.

New op­tions in­clude wheel­chair bays, in­stal­la­tions for bistro, a de­mount­able plat­form with pram area for in­ter-city lines or, with plat­form, the clas­sic seat­ing for tour­ing pur­poses.

Cus­tomers can choose be­tween the cock­pit from the Se­tra Com­fortClass 500, or the lux­u­ri­ous cock­pit from the Top­Class 500.

Evenly spaced two-tone steps with in­di­vid­ual light­ing, land­ings and con­tin­u­ous handrails give pas­sen­gers se­cu­rity when go­ing up and down the stairs, and the bath­room has been to­tally re­designed in 2017.
