Daimler Buses is expanding the range of functions available in its coach portfolio with new engines and transmissions, a new electronic architecture to enable additional safety assistance systems and digital services. The enhancements are complemented by a modernised driver's workplace. Depending on the model and vehicle configuration, Daimler states that fuel consumption can be reduced by up to six percent. The new technologies, demonstrated at the IAA Commercial vehicle show in Hannover (Germany), will be introduced in coaches of the Setra and Mercedes-Benz brands from 2027 onwards.
The fuel savings of up to six percent can be reached in combination with the new ZF EcoLife CoachLine and ZF TraXon 2 Coach transmissions helped by the further developed OM 470 and OM 471 diesel engines that have an optimised combustion process with precisely controlled and cooled exhaust gas recirculation. Newly developed coating for the diesel particulate filter and SCR system enhances the robustness of the exhaust aftertreatment system. The ZF EcoLife CoachLine automatic transmission can be found in the Mercedes-Benz Tourismo and the ZF TraXon 2 Coach automated manual transmission in the Setra ComfortClass and TopClass models. The engines have an extended oil change intervals of up to 480,000 kilometres or four years. With its new electronic architecture, Daimler Buses is laying the foundation for a new generation of safety and assistance systems. Active Sideguard Assist 3 can support drivers in critical turning and lane-change situations and help prevent collisions through targeted braking interventions. Active Cross Traffic Assist helps detect crossing vehicles at an early stage and can
automatically initiate braking when required. Active Drive Assist 2 supports drivers with speed, distance and lane guidance and can help reduce driver workload. The package is complemented by the Electronic Park Brake Control (ePBC) the new Active Power Steering 3 (APS3), which can automatically adapt steering assistance to driving situations and vehicle speed. The new Active Cross Traffic Assist is developed for traffic situations in which fast-moving vehicles or motorcycles approach from the side and cross the vehicle’s path. The system uses a 270-degree sensor fusion consisting of long-range radar, a multifunction camera, and short-range radar sensors. Within its detection range, it can identify vehicles and motorcycles approaching the truck or touring coach from the right or left and crossing its path. In all Setra and Mercedes-Benz vehicles the driver has an upgraded workplace with the Multimedia Cockpit Interactive, including a high-resolution main display, touchscreen and new multifunction steering wheel.
