The worlds largest and most important trade fair for mobility,transport and logistics -the IAA in Hanover,Germany-has just come to an end.This years IAA was all about commercial vehicles,since the focus is switching biannually between passenger and commercial vehicles.As the slogan Driving the future implies the IAA commercial vehicle was this time trying to show how the industry will develop in future,rather than unveiling myriads of new models,which is normally the case at the IAA passenger cars.
