San Luis Potosí has grown into one of Mexico's key automotive and logistics hubs, anchored by a full BMW Group assembly plant that opened in 2019 and is adding electric vehicle production and battery assembly from 2027, according to BMW Group. The city sits on Federal Highway 57 roughly midway between the Bajío and the Texas border crossings.

Automotive assembly and suppliers lead, with appliances, basic metals, and consumer goods alongside; freight runs mostly in dry vans up the Highway 57 corridor, with specialized equipment for vehicles and machinery.
BMW Group's decision to build its Neue Klasse electric vehicles and a high-voltage battery plant in San Luis Potosí from 2027, announced by the company in 2023, is one of the clearest signals of long-term manufacturing commitment to the corridor.
San Luis Potosí is the midpoint of Mexico's main freight artery. The city sits on Federal Highway 57 between the Bajío manufacturing belt and the Saltillo-Monterrey corridor, which puts nearly every northbound truck from central Mexico through its outskirts. Its own industrial base has scaled fast: BMW Group operates a full assembly plant here, opened in 2019, and the company has announced that its Neue Klasse electric vehicles and a high-voltage battery assembly plant will be built in San Luis Potosí from 2027. Other global automakers and a broad supplier base operate across the metro's industrial parks, joined by appliance and metals plants.
Service follows the central Mexico norm: door-to-door through-trailer moves with a transfer driver at the border, with transloading reserved for special cases. See transbordo for the tradeoffs. Mexican equipment vocabulary also matters here, since domestic legs may quote in torton or rabón straight-truck classes and capacity in metric tons rather than trailer counts. The Mexico 101 guides translate the taxonomy.
Post SLP loads with the true plant origin and disclosed commodity, and use domestic Mexico coverage on Cargado to handle intra-Mexico repositioning on the same network that covers the cross-border leg.
Post the load on Cargado with the true SLP origin, destination, equipment, and commodity, and vetted carriers working the Highway 57 corridor get notified automatically. The city benefits from corridor traffic between the Bajío and the border, so the effective carrier pool is larger than the city alone would suggest. Lead time and complete detail remain the strongest levers for fast coverage.
Full-size dry van, called caja seca and equivalent to the U.S. 53-foot trailer, covers most export freight. Domestic and shorter legs frequently quote in straight-truck classes Americans rarely see: the torton, a three-axle unit rated around 14 metric tons, and the smaller rabón. Mexican flatbeds also commonly run 40 feet rather than 48 or 53, and capacity is quoted in metric tons, so confirm dimensions rather than assuming U.S. specs.
Cargado connects 250+ brokers with 2,000+ vetted carriers on Mexico and Canada lanes.
