By 2008, smaller car makers -- those with production volumes of less than four million units per year -- will have made significant gains in their share of overall global vehicle production, according to CSM Worldwide. Production of the top six OEM groups in the light vehicle industry will grow at a pace of 1.8% on a compound rate from 2002 to 2008, the researcher said. This group includes General Motors, Ford, DaimlerChrysler, Toyota, Renault/Nissan and Volkswagen. Outside the traditional mass markets of the US, Canada, Western Europe, Japan and Australia, this same group will grow at a 6.3% rate.
