By buying the Mercedes-Benz Citaro Spillmann has opted once again for efficient hybrid components and the Sideguard Assist safety system. The radar-based Sideguard Assist supports the bus driver when making critical right turns. The system detects both stationary and mobile obstacles such as cyclists or pedestrians.
Citaro passengers can look forward to a very special interior because in addition to Wi-Fi, USB charging sockets and comprehensive infotainment, every vehicle is designed according to a theme. For example, there is a "Skipper" vehicle which has a floor made of ship planks and printed side walls that give passengers a view of the open sea or sandy beaches. In the "Astronomy" bus the floor is printed like the surface of the moon and the side walls show a view from the moon to the earth and into the universe. The "Bietigheim" vehicle visualises the highlights of the Bietigheim-Bissingen region on the side walls. The floor in this bus has a quarry stone design. In the "Vintage" bus, Spillmann has given the side walls a colourful 1960s design and it additionally features untreated steel handrails with a vintage character. In the Citaro articulated bus the seat colours create four different zones. This "mobility" bus features an asphalt flooring design including tyre tracks and central reservation.
