Mexico’s Automotive Industry is Already Too Large to Relocate

With 25% of the country’s industrial inventory and billions in 2026 investments, Mexico’s automotive sector is proving that its resilience is not optimism. It’s structure.

While political discourse in Washington continues pushing to relocate manufacturing away from Mexico, several automakers are still deepening their commitment to the country. This year, Audi announced new hiring plans and, alongside General Motors, identified Mexico as one of its markets with the greatest growth potential. At the same time, companies such as Bajaj, Brose, Chevrolet, Leoni Wiring Systems, and Topsun continue advancing production expansion plans that together exceed $2.4 billion and nearly 15,000 direct and indirect jobs over the next two years.

The logic behind those investments goes beyond labor costs or tariff conditions, because what automakers now operate in Mexico is no longer just assembly capacity, but an integrated manufacturing network that took decades to build, has become extremely difficult to replace, and also helps explain both the industry’s geographic concentration and the type of capabilities that continue to expand within the country.

It is no coincidence that many of the most recent investments—Audi in Puebla, Brose in Querétaro, Chevrolet in Coahuila and Topsun in Guanajuato—are concentrated in Mexico’s Bajío and northeastern regions, where, according to SiiLA, 84% of the country’s occupied automotive industrial space is located, and where, according to INEGI¹ data, the strongest automotive business growth of the past decade has been concentrated alongside Puebla. In other words, these are corridors where integrated suppliers, specialized engineering, technical universities, and logistics infrastructure are already deeply established.

Nor is it surprising that, within this environment of regional integration and specialization, the sector’s business expansion has been concentrated less in automakers and more in Tier 1 suppliers²—companies that provide complete systems directly to automakers, such as transmission, interior, or electrical systems—precisely the layers that are most difficult to reconfigure within the North American manufacturing chain.

INEGI¹ data show that between 2016 and 2026, establishments associated with Tier 1 suppliers grew nearly 40%, far above the rest of the automotive chain, including Tier 2 companies—largely parts suppliers—which expanded 8.6%. This occurred in a context where the total number of establishments linked to vehicles and auto parts increased from 2,673 to 3,457—a 29.3% increase that survived the pandemic, withstood two rounds of tariff pressure, and posted its strongest recent annual rebound in 2026, rising 5.5%.

Automotive expansion favored capabilities that are difficult to replace within North America.

However, the automotive sector’s share of total manufacturing remained virtually stable—around 0.5%—throughout the decade¹, suggesting that it did not grow faster than the rest of Mexican manufacturing, but rather deepened its integration within it.

That also does not mean the sector is undergoing a frictionless expansion cycle. Although Mexico’s automotive integration continued consolidating during those years, its business base registered a slight 1.7% contraction in 2025¹—the only significant annual decline during the period—and so far in 2026, the sector has shown more moderate expansion in terms of absorption, occupancy, and production, consistent with a manufacturing slowdown and weaker economic momentum in the United States.

Despite those headwinds, the physical scale of integration helps explain why the sector still retains expansion capacity even in a less dynamic and more geopolitically complex environment.

Currently, vehicles and auto parts occupy more than 25.3 million square meters of industrial space in Mexico—a quarter of the country’s total inventory. Relocating infrastructure at that scale would require moving thousands of production lines and replicating manufacturing ecosystems whose viability depends on production synchronizations that extend far beyond political or commercial cycles, and whose viability does not respond solely to tax incentives.

That is where the difference lies between a commercial cycle and an industrial transformation. While that debate continues, automakers keep voting with their capital. And so far, their capital continues choosing Mexico.

¹ The analysis was prepared using the National Statistical Directory of Economic Units (DENUE) published by INEGI between 2016 and 2026. The sample includes manufacturing establishments in the vehicle and auto parts industry under the North American Industry Classification System (NAICS). To construct the historical series, annual directories were integrated by standardizing state entities and filtering the selected NAICS codes for the automotive sector (336110, 336120, 336210, 336310, 336320, 336330, 336340, 336350, 336360, 336370, 336390, and 336991). State participation shares were calculated as a proportion of the national total of identified establishments in each year. Changes in participation reflect variations in each state’s relative weight within the national automotive sector, not economic growth, production, or employment. Base-100 indices use 2016 as the reference year to measure the evolution of the number of establishments during the analyzed period. Due to DENUE’s administrative nature, results reflect registered establishments rather than installed capacity, physical production, investment, or operational scale.

² The tier-based functional classification used in this analysis is referential and intended for analytical purposes. It does not represent specific contractual relationships between suppliers and automakers. Groupings were based on the typical function of each NAICS activity within the automotive chain: a) OEM / Final assembly: manufacturing of automobiles, pickups, trucks, tractor-trailers and motorcycles; b) Approximate Tier 1: manufacturing of integrated systems and components used directly in final assembly, including engines, electrical and electronic systems, transmission, brakes, steering, suspension, seating and interiors; c) Approximate Tier 2: manufacturing of intermediate components and parts used by Tier 1 suppliers; d) Body manufacturing and specialized equipment: manufacturing of bodies, trailers and specialized configurations separated from conventional assembly due to their hybrid role within the production chain. The selection prioritizes manufacturing processes directly linked to automotive integration and excludes primary industrial inputs typically associated with Tier 3 suppliers.
