The major economic engine for the municipality is the Daimler Vehículos Comerciales Mexico plant, locally referred to simply as “La Mercedes.” The main Industry is automotive production centered around vehicle manufacture, design, and vehicle R&D. The building has been in operation since 1969 and is the only place where the Coronado tractor trailer is made. It began as a factory named Autocar. Ten years later it became a store affiliated with the Famsa chain until it was acquired by Mercedez-Benz de Mexico in 1991. Since then, the factory has produced more than 272,000 Mercedes-Benz vehicles. A Daimler Trucks factory is also located in this facility, which produces its Freightliner Trucks in its own plant. The trucks are primarily produced for export, mostly to the United States, Canada and Latin America.
