Texas-Mexico Automotive SuperCluster

Manufacturing Powerhouse
Competitive Advantage

The Texas-Mexico Automotive SuperCluster (TMASC) region is a bi-national region that consists of Texas, Tamaulipas, Nuevo Leon, Coahuila and San Luis Potosi.

TMASC is home to 27 automotive assembly and parts assembly plants. The region also has over 230 OEM supplier plants with strong clusters in Dallas-Fort Worth, San Antonio, along the Monterrey-Saltillo corridor, and straddling the border in the Lower Rio Grande Valley.

The TMASC initiative, created by Bexar County Economic Development and launched in 2008, is a collaborative strategy aimed at developing and diversifying the automotive industry throughout the region for job creation/retention and for new capital investment.

Over 30 organizations and companies from throughout Texas and Mexico in the private, public, and academic sector partner with TMASC to develop the region's manufacturing capacity and to recruit new investment. 
  • 8 automotive assembly and parts plants
  • 7 commercial and military vehicle plants
  • 9 heavy equipment manufacturers
  • 3 specialty vehicle plants
  • Over 230 OEM supplier plants
  • 17 million worker labor pool
    A supplier listing for Bexar County is now available for manufacturers seeking to source components in the south central TMASC region. The Excel file is sortable by NAICS codes and features manufacturers operating across advanced manufacturing industries, e.g. automotive and aerospace.

    This listing proves the County’s manufacturing base goes beyond Caterpillar and Toyota operations. In fact, the initial 81 supplier list reflects actors throughout the supply chain who solidify and support larger assembly plants in the TMASC region.

    Bexar County Economic Development's role in creating and compiling the list is focused on strengthening the region through conveniently available and timely data, particularly as automotive and heavy equipment assemblers continue their southern migration and seek localized suppliers.

    Within the coming months new listings are scheduled for TMASC partner regions - Houston, McAllen, and Temple.
