Introduction: The Landscape of the Automotive Supply Chain
The global automotive supply chain is dominated by a group of massive, multinational corporations known as Tier 1 suppliers. These companies design, manufacture, and sell complex systems and modules directly to car manufacturers (OEMs – Original Equipment Manufacturers). They are critical to the industry’s evolution, especially in the shift towards electrification, connectivity, and automation.
