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.
