Industry 4.0, an integral part of the Fourth Industrial Revolution, portrays techno-logical advances and affects the way of management along with the automotive chain, with its pillars offering greater opportunities for all members along the chain. This article aims at identifying and analyzing the difficulties of automakers and auto parts for the use of relevant technologies for Industry 4.0 in order to promote supply chain integration. The data were collected through a survey, carried out with managers from the industrial area of companies in the automotive segment (automakers and auto parts) in Brazil. The results showed that data connectivity and collaboration along the chain are the main bottlenecks for the use of new technologies, which the level of investment, especially in auto parts is insufficient. Despite the interdependence among companies surveyed, the automakers are in a more advanced stage while the technological gap is more evident by the auto parts. These divergences make the integration of these companies even more difficult.
