Audi Hungaria established a modern logistics infrastructure to ensure the smooth production operations. Integrated smart solutions, such as modern automated guided vehicles and digital tools support the logistics processes. The internal material flow is controlled so that only those parts that are directly required in the assembly process are made available. This eliminates costly intermediate stores and productivity increases as a result. Environment-friendly rail transport is the primary mode for basic materials, parts, finished engines and automobiles. The new rail network installed as part of the plant expansion is eight kilometers (5.0 mi) long. The railway inside the plant grounds was lengthened by 30 percent. Audi Hungaria has continuously expanded the logistics infrastructure in recent years. The company erected its second logistics center on an area of 80,000 (861,112.8 sq ft) in 2015. Also added were a new bridge and an additional incoming goods hall.
