Walking IAA 2016, the world's largest truck show

Every other year global truck manufacturers gather in Hannover, Germany for a celebration of commercial vehicles now known only by its initials IAA.  Spanning over a dozen buildings, the displays range from the smallest components to the heaviest haulers.  Current products in bright graphics mix with flashy hi-tech concept vehicles during two days of press conferences for a global media audience followed by crowds of truck buyers and tire kickers.  Here are just a sampling of IAA 2016's highlights.
