Comparing Size And Output
Plants like Wolfsburg and Ulsan are the biggest in the world in terms of size and production, but smaller plants can still have a major cultural impact along with the boost they bring to the local economy. The Rouge Complex and Willow Run helped shape American automotive history, while Tesla’s Gigafactories define the future. Together, they show the evolution of automotive scale.

Beating Hearts Of Production
Automotive plants are a reflection of the vision and ambition of their makers. From Wolfsburg’s sprawling city-like layout to Ulsan’s record-setting output, these giants showcase the scale of the global car industry as an endeavor for those who think big and make things happen. The same is true for the closed plants of the past, reminding us all that even the biggest operations have to evolve, or else fade into history.
