Latest / The Productivity Podcast with Fexingo: Output, Efficiency, and Long-Term Economic Growth / How Mexico Built the World's Most Productive Auto Manufacturing Hub
Transcript
- Lucas: Mexico produced more cars last year than Germany. That fact still stops me when I think about it. Luna: It's a huge number — almost four million vehicles in 2025. And it's not just volume; the productivity story underneath it is really interesting. Lucas: Right. For years, the narrative was that Mexico was a cheap labor haven. But the data tells a different story. Labor productivity in Mexico's auto sector grew at a compound annual growth rate of 3.8 percent between 2010 and 2025. That's faster than the United States, faster than Germany, faster than any other major auto producer. Luna: So it's not just about wages being lower. It's about how efficiently that labor is used. Lucas: Exactly. And the best case study is Aguascalientes. That state, in central Mexico, now produces more vehicles per worker than Michigan or Bavaria. It's a cluster that Nissan essentially built from scratch starting in the 1980s. Luna: What made Aguascalientes different from other manufacturing hubs in Mexico? Lucas: Three things. First, Nissan and later Renault invested in a truly integrated supply chain within a 50-kilometer radius. Tier-one suppliers like Bosch and Denso co-located, so parts don't travel far. Second, the state government invested early in technical education — a dual-training system modeled partly on Germany's, where students split time between classrooms and factory floors. Luna: That's the sort of long-term policy move that usually takes a decade to pay off. Lucas: And it did. The third factor is that plants in Aguascalientes adopted lean manufacturing and automation at a pace that surprised a lot of people. By 2020, the Nissan plant there had over 1,500 robots, but it also retrained workers to maintain and program them. So it wasn't automation replacing labor — it was automation augmenting labor. Luna: That's a really important distinction. A lot of people hear 'productivity' and think 'job losses.' Lucas: And in some places that's true. But in Aguascalientes, employment in the auto sector nearly doubled between 2010 and 2025, even as output per worker soared. Wages also rose — not to German levels, but faster than the Mexican average. The real wage in auto manufacturing there grew about 2.5 percent annually after inflation. Luna: So the productivity gains were shared, at least partially. What role did nearshoring play after 2020? Lucas: It accelerated everything. When companies started looking for shorter supply chains and more reliable partners, Mexico was the obvious candidate. Foreign direct investment into Mexican auto manufacturing jumped from about $3 billion a year pre-2020 to over $6 billion annually by 2023. That capital went into newer, more efficient plants. Luna: And a lot of that investment came from companies that had previously sourced from China. Lucas: Right. Tesla announced a new plant in Nuevo León. BMW expanded in San Luis Potosí. And those new facilities are designed with Industry 4.0 standards from day one — connected sensors, predictive maintenance, digital twins of the production line. That's a productivity leap over older plants that have to retrofit. Luna: It also helps that Mexico's energy costs have been relatively stable. Natural gas from the US pipeline network keeps electricity prices competitive. Lucas: That's a huge factor. And here's a detail I really like: the auto sector in Mexico now sources about 25 percent of its electricity from wind and solar. That's partly because large manufacturers like Nissan and Volkswagen signed power purchase agreements to lock in renewable energy. It's not just a green story — it's a cost story. Wind and solar are now cheaper than grid electricity in many parts of Mexico. Luna: So lower energy costs, higher labor productivity, and supply chain proximity to the US market. That's a powerful combination. Lucas: It is. But there are risks. One is automation itself. As robots get cheaper and more capable, the labor cost advantage erodes. If a Mexican worker costs $5 an hour and a US worker costs $30, but a robot can do the job for $4 an hour in both countries, the wage gap doesn't matter anymore. Luna: That's a real threat. But it doesn't affect all processes equally. Some assembly tasks are still very hard to automate. Lucas: Exactly. The wiring harness — those bundles of cables that run through every car — is still largely done by hand. It's tedious, complex, and hard to robotize. So that kind of work will likely stay in Mexico for a while. Luna: But the higher-value parts of the supply chain, like powertrain manufacturing, are more automated. If those processes become fully robotized, Mexico could lose some of the higher-wage jobs. Lucas: That's the big question. Can Mexico move up the value chain fast enough? The country has been trying to attract more R&D centers. General Motors has a tech center in Mexico City. Continental has engineering hubs. But the share of Mexican auto exports that are 'high-tech' — engines, electronics, advanced components — is still only about 35 percent, compared to over 50 percent for Germany. Luna: So the productivity gains so far have been in assembly and basic manufacturing. The next phase has to be about innovation. Lucas: And that requires a different kind of workforce. Which brings us back to education. Mexico spends about 5 percent of GDP on education, in line with the OECD average, but the quality varies hugely. The dual-training model in Aguascalientes is a success, but it hasn't been replicated nationwide. Luna: It's interesting that you mentioned the German model earlier. Germany's productivity lead in manufacturing is partly built on its vocational system. Mexico is trying to adopt elements of that, but it's a long-term project. Lucas: And the clock is ticking. Because other low-cost countries are also improving. Vietnam, for example, has been investing heavily in electronics manufacturing. India is pushing its 'Make in India' program. Mexico's window of advantage may not stay open forever. Luna: But for now, the numbers are impressive. What's one concrete metric that sums up this episode for you? Lucas: Labor productivity in Mexico's auto sector grew at a compound annual growth rate of 3.8 percent from 2010 to 2025. That's nearly double the US rate over the same period. If Mexico can sustain that pace — and move into higher-value production — the next decade could be even more transformative. Luna: And if listeners want to dig deeper, they should look at the data from the Mexican Auto Industry Association. It's surprisingly transparent. Lucas: Absolutely. And speaking of transparency — and of keeping this show ad-free — a couple of dollars a month is genuinely what keeps these episodes going. If walking through the economy with us has made something click, buy me a coffee dot com slash fexingo. It's the easiest way to support the podcast, and it really does make a difference. Luna: Yeah, every bit helps us stay independent and focused on the stories that matter. No ads, no sponsors, just the research. Lucas: Right. And speaking of stories — the next episode is going to look at how India's pharmaceutical industry achieved world-class productivity. That's a fascinating case of reverse innovation, where low-cost manufacturing actually drove improvements in quality and output. Luna: That's a great one. Thanks for listening, everyone. Lucas: We'll see you next time.
