Frankfurt Auto Show 2011, Frankfurt, Germany

• 1989: Last IAA to feature both cars and commercial vehicles at the exhibition site in Frankfurt. More than 1.2 million visitors attended the event, setting a new record.
• 1991: The IAA is subdivided in two. From this point on, in odd-numbered years the IAA Passenger Cars continues to be held in Frankfurt; starting in 1992, even-numbered years will see the IAA Commercial Vehicles in Hanover.
• 2001: The September 11 terror attacks cast a shadow over the IAA, which nevertheless went ahead only two days later. As a mark of solidarity with the victims, all show elements and loud music as well as the official opening ceremony with the Federal Chancellor were cancelled. VDA President Gottschalk explained this decision: "Because we could not permit terrorist forces to take away our freedom of action. And because, as a key international sector, we have a responsibility not to allow things to grind to a halt."
• 2003: For the first time, the passenger car-only exhibition in Frankfurt breaks the barrier of one million visitors. It features 2000 exhibitors from 42 countries.
