BMW’s San Luis Potosi facility is a testbed for next-generation automotive production. From digital twins and AI to high-voltage battery assembly, it pioneers lean, green, and smart manufacturing to meet global demands for electrification and sustainability.
The term “BMW” tends to conjure up images of a vehicle manufacturer that is deeply “Deutsch,” but such a concept is, at the very least, incomplete. BMW’s Mexican plant in San Luis Potosi (SLP), 230 miles northwest of Mexico City is, despite being climatically classified as a ‘semi-desert’, at the vanguard of smart automotive manufacturing, embodying the OEM’s bold vision for the “Factory of the Future.”
Since its opening in 2019, SLP facility has quickly evolved into one of the most advanced manufacturing hubs in BMW’s global network. Designed with flexibility and innovation at its core, the plant reflects the automaker’s commitment to meeting the evolving demands of global markets. As the industry pivots toward digitalisation, electrification, and sustainability, SLP stands as a model for how these principles can be integrated into automotive production—even in the most challenging geographical and economic environments.

At the heart of this transformation is BMW’s iFACTORY strategy, a framework that prioritises lean, green, and digital principles. The implementation of digital technologies at SLP is not merely an upgrade to the OEM’s existing processes; it represents a huge leap forward for automotive production.
But why the digital push at the semi-sandy site? An oft-referenced Mckinsey report shows that automotive manufacturers “nearing the tipping point of digital adoption” are clearly achieving “even faster and more sustainable change” through digital adoption. With the site strategically located to serve the US and other relevant markets, digitisation is critical to the site’s success.
The San Luis Potosi plant produces vehicles for both the domestic Mexican market and key export destinations, including North America, Europe, and Asia.
Key focuses include:
-
North American Market: A significant portion of the vehicles manufactured at the San Luis Potosi facility are sold in the United States and Canada. These markets remain crucial for BMW’s sales due to strong demand for premium vehicles.
-
European and Asian Markets: Cars produced in Mexico are also exported to Europe and Asia, aligning with BMW’s global distribution network. The plant’s strategic location and Mexico’s free trade agreements (such as USMCA, EU-Mexico, and CPTPP) provide tariff advantages and facilitate these exports.
-
Domestic Market: The Mexican market also absorbs a portion of the production, catering to the growing demand for luxury vehicles within the country.
This global distribution strategy leverages the plant’s efficiency and its ability to produce models like the BMW 3 Series and 2 Series Coupé, tailored to meet specific regional market demands.
Every corner of SLP has been meticulously designed to embrace digitalisation, from virtualisation and artificial intelligence (AI) to real-time data analytics and advanced robotics. This level of sophistication not only future-proofs the plant but also positions it as a testbed for innovations that could potentially reshape the automotive industry worldwide.
Digital battery blueprints and the role of virtualisation at SLP
One of the most striking aspects of SLP’s digitalisation journey is its use of virtualisation. With the automotive industry accelerating toward electrification, BMW is making substantial investments at the site in preparation for the future.
An additional €800 million ($843 million) has now been allocated to expand the facility, including €500 million ($527 million) dedicated to constructing a high-voltage battery assembly plant.
Spanning 85,000 sq.m, the expansion will produce batteries to be integrated directly into the vehicle structure of the Neue Klasse, further streamlining production and reducing complexity. The battery centre extension was meticulously captured in 3D to create digital twins of its physical spaces. These digital replicas are, more than just being visual tools, dynamic digital platforms for critical planning and optimisation.
“These [digital and lean] disciplines are fully digitally modelled, and we validate them during the design phase so that we can have far fewer issues during the construction phase of the project”
- BMW, San Luis Potosi
On our recent trip to the Mexican site, a BMW spokesperson explained: “For the design and construction, we implemented two main methodologies. The first of them was the BIM technology, which is ‘Building Information Modelling’. With this model, we have a 3D representation which will be an input for our digital factory which also helps us in the development of our production centre and to identify situations where we can easily solve problems.
“The second was ‘lean manufacturing’, again, something which would not have been possible without the power of digital models underpinning it,” noting that this approach allows BMW to “identify clashes between different disciplines and trades” early in the design process, thereby minimising disruptions during construction and ensuring smoother operations at launch.
“These disciplines are fully digitally modelled, and we validate them during the design phase so that we can have far fewer issues during the construction phase of the project.”
This capability is invaluable as BMW prepares to manufacture its Neue Klasse electric vehicles at SLP beginning in 2027. With this digital environment, engineers can simulate new production lines, test workflows, and identify bottlenecks—all before any physical changes are made. This virtual-first approach ensures minimal disruption to existing operations while accelerating the rollout of new vehicle architectures.
”We are able to conduct a visual inspection based on sampling, inspecting 100% of weld points as well as other important characteristics of the body”
- Héctor Galán Ramírez, Body Shop Department Manager
Artificial Intelligence: redefining quality and efficiency
Artificial intelligence is central to the SLP plant’s operations, touching many stages of production. In the body shop, for instance, AI has been integrated into sensors embedded in robots and welding tools that continuously monitor critical parameters like temperature, pressure, and vibration. These sensors feed predictive analytics models that anticipate equipment failures before they happen. This shift from reactive to proactive maintenance ensures uninterrupted production and extends the lifespan of costly machinery.
Héctor Galán Ramírez, Body Shop Department Manager, highlighted AI’s role in maintaining this level of precision:
“We utilise many AI tools for process control. Our technology can detect any variation in the process and if absolutely necessary, even stop the production line. In the end, this level of smart control ensures the quality of the process as well as the final product.
“Additionally, we are able to conduct a visual inspection based on sampling, inspecting 100% of weld points as well as other important characteristics of the body. This falls in line with our commitment to quality assurance through innovative technology at SLP.”
“One project within this programme involves using virtual reality to teach safety rules and basic robotic components”
