The use of new technologies to connect people, equipment and machines, i.e. Industry 4.0 is a key player in the manufacturing processes of all industries, as well as in the automotive industry. The Industry 4.0 application in the automotive industrial environment brings smart automation in the automotive element manufacturing process, as well as the car assembly process. The automotive industry is ranked first in the Insuatria 4.0 application in manufacturing processes, and the reason is the global market where every automotive company wants to be a leader. So far, the automotive manufacturing processes have been automated for decades and have been quite automated, but rigid automation has been required. To establish full connectivity to the manufacturing process, there was a lack of wireless connectivity and communication, or production networks where information carriers communicate with each other and exchange data and data. Real-time information, making automation more flexible, improving productivity as well as quality itself. Manufacturers are given the opportunity to quickly adapt the production of other products, which has not been the case so far. The paper presents trends in the use of second-generation service and industrial robots, as well as the use of smart sensors to increase the quality of production and assembly. Industry 4.0's application in the automotive industry has been growing day by day until production processes become completely intelligent.
