The IAA will take place in Frankfurt Sept 13 through Sept 25, with the first two days reserved for the international press.
Matthias Wissmann, president of the German auto industry association (VDA), said: "We expect a strong show, with more exhibitors, more visitors and even more innovation."
At a press conference, Wissmann said the 64th Frankfurt auto show will focus heavily on innovation in the industry. Electro-mobility will be one of the focal points of the event, he said.
The VDA president said he expected around 900 exhibitors, up from 710 two years ago. With five months to go, the VDA has already registered 600 exhibitors from 35 countries.
Among companies that will be present this year are several who cancelled their appearances in 2009. These include automakers Honda, Mitsubishi, Isuzu, Ssangyong, Chevrolet and Cadillac.
New to the show will be South Korea's AD Motors, Japan's Infiniti and China's Changan.
