Design/methodology/approach – The authors’ research follows an interpretive case study methodology based on a theoretical approach that seeks to validate the approach while making conclusions about the case study.Findings – The traditional pyramidal structure of automotive supply chains has been altered by theconsolidation of a much more complex structure, mostly in spatial and geographical terms. The authors find a strong hierarchy resulting from the reinforced market power of the carmaker under study and the respective fragile structural positioning of logistics companies and pre-assemblers. The increased versatility of the assembly plant, considered a consequence of its transition to modular platforms, finds a counterpart in the necessary re-configuration of certain supply relationships.Originality/value – The main contribution of the paper is to connect the defining elements of supply-chain relations with those technical and organizational changes associated with the transition to modular platforms,as well as to analyze changes in the pyramidal structure of the supply chain, from both a spatial and relational perspective %~
