Non-Governmental Organization
International Organization of Motor Vehicle Manufacturers

OICA is comprised of 38 national trade associations around the world, including all major automobile manufacturing countries, thereby covering virtually the entire motor vehicle industry all over the world.

OICA’s general purposes are to defend the interests of the vehicle manufacturers, assemblers and importers grouped within their national federations and, in particular:

  • Link the national automobile associations,
  • Study issues of mutual interest relating to the development and future of the automobile industry,
  • Collect and circulate useful information among member associations,
  • Establish policies and positions on issues of mutual interest to the members,
  • Represent the automobile industry at the international level, in particular with intergovernmental and international bodies,
  • Disseminate and promote industry policies and positions among international bodies and the general public.

You can find more information about OICA at their website.
