Frankfurt Auto Show 2011, Frankfurt, Germany

• 1965: First Japanese cars at the IAA
• 1971: What would have been the 45th IAA was cancelled at short notice on political grounds in order to discourage passenger car purchases. That was the moment where the idea of "Automechanika '71, International Exhibition for Automobile, Workshop, Filling Station and Garage Equipment" arose. Thus Messe Frankfurt gave the automobile, equipment, accessories and other companies normally represented at the IAA the chance to make presentations.
• 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.
