The NEOPLAN Tourliner - leading the way in CO2 reduction through aerodynamically optimised design Optimised consumption with consideration to various vehicle requirements

In order to significantly reduce the vehicles consumption, a lot of attention was paid to its streamlined design. The goal was to also use aerodynamics to influence and significantly reduce the consumption. During the design phase, each detail was therefore looked at closely in order to determine how to implement the NEOPLAN design criteria, specific vehicle design and detailed design in a way that optimises the cW value. Through optimisation loops, we found a target-oriented design with calculated solution approaches and implemented this meticulously in the area at the front of the bus, the front roof dome, the mirrors, the air-conditioning system cladding, the wheel arch panels, wheel trim, entire rear panel, as well as areas in the underbody. The results were then examined on a scale model in a wind tunnel and confirmed through test drives of initial vehicles. The cW value was reduced by over 20% in comparison to the first Tourliner (2002), from 0.46 (good at that time) to 0.36 now. The vehicle therefore achieves overall fuel savings of 10% in comparison to the predecessor bus, reducing consumption to an average of approx. 20 litres per 100 km. This represents a high degree of innovation, as the improved consumption is in a standard, entry-level vehicle of the NEOPLAN brand. The standard Tourliner not only has a more attractive acquisition cost it is also designed to reduce consumption. More for people and the environment! This is illustrated through images, graphics and short films.
