This research aims to compare the cultural dimensions of the automotive industry in three countries, Brazil, Argentina, Mexico and discuss Hofstede model. Were using two techniques of analysis, the first being described in the model of Hofstede and Minkov (2013) and the second using the statistical technique indicated by critics of the model (McSweeney, 2013). The results found in regions of Brazil and Mexico indicate that in the same country there may exist different values of cultural dimensions. Regarding the critics indicated in the literature on the model used, this study found evidence in line with the critics that the model, although pointing to cultural differences are not supported by statistically significant differences, to measure and compare cultures between countries. As a contribution, this study indicates the need for the proposed model to consider robust statistical techniques, probabilistic sampling and comparative statistical analysis techniques to prevent misdiagnosis.
