The Texas-Mexico Automotive Supercluster (TMASC) is a rapidly growing area that spans both Texas and northern Mexico. It’s a key part of the automotive industry, attracting major companies and investments to the region, and has a direct impact on Bexar County, especially San Antonio. The supercluster includes over 14 vehicle assembly plants and several major corporate headquarters, making it one of North America’s most important automotive hubs.
Over the past decade, TMASC has attracted over $10 billion in investments, resulting in the creation of thousands of jobs in the automotive manufacturing sector. Approximately 170,000 new jobs have been created within the region, with a substantial number located in Bexar County alone. These jobs are not just for skilled workers—they also provide training opportunities for residents, equipping people with the skills necessary to succeed in the expanding automotive industry.
Several large companies are part of TMASC, including well-known names like Toyota, Tesla, BMW, and Kia. Tesla’s Gigafactory in Austin, just a short distance from San Antonio, is one of the newest additions to the area. Other companies such as General Motors, Caterpillar, and Navistar have also expanded their operations here. These companies have established plants and headquarters, contributing to the region’s status as a strong contender for future automotive investments.
The economic impact of TMASC is significant. The region contributes approximately $18 billion to the local economy, with manufacturing accounting for a significant portion of that. Automotive manufacturing is not just about building cars; it also supports thousands of suppliers and service industries, from parts manufacturers to logistics companies. In addition to direct manufacturing jobs, TMASC has also helped establish a strong supplier network, attracting Tier 1 and Tier 2 suppliers to support the major automotive companies in the region.
Looking ahead, the future of TMASC in Bexar County is bright. The area is well-positioned for growth, especially as the shift toward electric vehicles (EVs) and clean energy becomes more prominent. Companies are investing in electric vehicle production, and the region is already home to several important EV manufacturing plants. As more companies focus on sustainability, Bexar County could attract even more green energy investments, further boosting job creation and economic growth.
