Project study on energy-efficient trucks by using aerodynamic principles

The German Association for Research in Automotive Technology (FAT) belongs to the German Association of the Automotive Industry e.V. (VDA).

In a FAT project study, six major players in Europe's commercial vehicle industry joined forces and dedicated themselves to this challenge for about a year. The overall aim was to optimize aerodynamics in order to decrease CO2 emissions and fuel consumption of commercial vehicles.

Financial support for this project was provided by the German Association of the Automotive Industry. The collaborating partners were: Daimler, Iveco and MAN (product: road tractor) along with Kögel, Krone and Schmitz Cargobull (product: semi-trailer).

FluiDyna examined the aerodynamic characteristics of commercial vehicles by conducting all numerical and experimental investigations. Furthermore, FluiDyna was responsible for the development and assembly of a wind tunnel model and execution of all required wind tunnel tests.

Taking into account the current European directives on commercial vehicle design, FluiDyna pinpointed some of the hitherto untapped potential for aerodynamic optimization of future generations of commercial vehicles. 

The final 69-pages report was published on November 2, 2011 and may be downloaded from the VDA's homepage (scientific series 237).
