This study aims to evaluate the possible theoretical relationship between strategic groups of the Brazilian automobile industry and the performance of companies belonging to these strategic groups. To achieve this goal, were analyzed 30 car assemblers companies, identifying strategic groups, using Michael Porter s typology as a base. After the identification of competitive strategies, analysis was conducted on the performance of the groups, observing how the strategic groups present within this industry. Data were statistically analyzed (Z-score, Shapiro-Wilks, factor analysis, K-means clustering, ANOVA and MANOVA), allowing more consistent analyzes of the strategic co-alignment of industry companies concerned. As a result, five strategic groups were found, with significant differences between their average performances for some dependent variables, highlighting the Consumer Satisfaction variable. This difference between the average performances of strategic groups indicates the importance of studying the competitive strategies of the particular industry companies, suggesting a possible theoretical relationship between strategy and performance.
