MAN showing progressive truck design study at IAA 2010

Minus 25 percent CO2 thanks to sophisticated aerodynamics: MAN Concept S a radical departure from usual truck design.

A drastic reduction of fuel consumption and CO2 emission by diesel trucks is possible and can be implemented in a short space of time. This is conclusively demonstrated by a design study from MAN Nutzfahrzeuge being shown for the first time at the IAA 2010 in Hanover.

The streamlined semitrailer tractor differs radically from today's typically cube-shaped trucks. The design of the MAN Concept S was rigorously adjusted in the wind tunnel in order to achieve extremely low wind resistance, corresponding to that of a modern passenger limousine.

Thanks solely to its aerodynamic form, the MAN Concept S – with an appropriately modified trailer – uses up to 25 percent less fuel than a comparable, conventional 40-tonne semitrailer tractor. This is the equivalent of a reduction in CO2 emissions of 25 percent.

With its Concept S, MAN makes a contribution to the current discussion on the statutory length restrictions applying to commercial vehicles in Europe. In order to realise the efficiency potential proven by the Concept S, tractors and trailers will have to become longer if they are going to provide the accustomed amount of interior space and loading volume. Changes to the road infrastructure for this purpose will not be necessary.
