Borderlands Mexico is a weekly rundown of developments in the world of United States-Mexico cross-border trucking and trade. This week in Borderlands Mexico: China automakers gain ground in Mexico as U.S. exports soften; OmniTRAX restarts Central Texas rail line with quarry deal; and China’s Windrose delivers first Class 8 EV in US, targets long-haul market.

U.S. finished-vehicle exports to North America are showing early signs of softening, just as Chinese automakers rapidly gain market share and expand their footprint in Mexico — a shift that could reshape cross-border automotive freight flows.

Passenger vehicle exports from U.S. plants showed signs of cooling early in 2026, according to preliminary trade data, though detailed country-level figures for February have not yet been released.

At the same time, new data from Mexico underscores the strength of the market that Chinese automakers are targeting.

Mexico produced 343,520 light vehicles and exported 310,205 units in March, with exports rising 4.2% year over year, according to the latest data from Mexico’s National Institute of Statistics and Geography (INEGI).

For the first quarter, Mexico exported 795,631 vehicles, up 2.5% from a year earlier.

The figures highlight Mexico’s continued role as a critical production and export hub — even as competitive dynamics begin to shift.

Mexico is emerging as a key battleground in the global auto market.

Chinese automakers including BYD and Geely have rapidly expanded their presence in Mexico in recent years, benefiting from competitive pricing and fewer trade barriers compared to the United States.

Their ambitions are now moving beyond imports.

Both companies are among finalists seeking to acquire a Nissan–Mercedes-Benz assembly plant in Aguascalientes, a move that would give Chinese automakers a direct manufacturing foothold in Mexico, according to Reuters.

The facility has capacity to produce about 230,000 vehicles annually and offers an established workforce and logistics infrastructure — making it a faster path to scale than building a new plant from scratch.

Industry estimates show Chinese brands have already grown from negligible market share earlier in the decade to roughly 10% of Mexico’s vehicle market, with further gains expected as more models enter the country.

Beyond Mexico, Chinese automakers are also expanding their regional supply chains. BYD recently secured 100,000 vehicle export orders from Argentina and Mexico from its Brazil plant, underscoring its growing footprint across Latin America, CarNewsChina.com reported.

While Mexico is the immediate growth market, Canada is increasingly viewed as the next opportunity.

BYD has said it is studying the Canadian market for a wholly owned manufacturing plant and is open to acquiring an existing automaker to accelerate expansion, according to Electrek.

The move comes as Canada has begun lowering barriers to Chinese EV imports, creating a potential entry point into North America that remains largely closed in the United States.

The expansion of Chinese automakers comes at a time when U.S. finished-vehicle exports are beginning to show signs of softening.

Canada and Mexico account for a large share of U.S. vehicle exports, supported by decades of integration under the United States-Mexico-Canada Agreement.

But shifting market dynamics — including rising Chinese market share in Mexico and potential new production capacity — could gradually erode that position.

Mexico’s export data also highlights the scale of the competitive challenge. The country shipped more than 310,000 vehicles in March alone, with the U.S. still accounting for roughly 76% of exports, underscoring how tightly linked the two markets remain.

For freight markets, the implications are significant.

Finished vehicles move via truck, rail and port networks tied closely to cross-border trade. A sustained shift toward Chinese automakers — particularly if production moves into Mexico — could:

Reduce U.S.-to-Mexico finished vehicle export volumes

Increase Asia and Latin America-to-Mexico import flows

Boost Mexico domestic distribution and export diversification

Reshape demand for railcars, car-haul capacity and cross-border trucking

Detailed U.S. trade data breaking out February vehicle exports to Canada and Mexico has not yet been released, but early indicators suggest a market in transition.

If Chinese automakers succeed in establishing manufacturing capacity in Mexico — and expand further into Canada — North America’s automotive trade could begin to rebalance.

For U.S. exporters and freight providers, that shift may mark the start of a new competitive era — one where vehicle flows are no longer defined solely by North American production, but increasingly by global players reshaping the region from within.

OmniTRAX is reviving a dormant Central Texas freight corridor after completing infrastructure upgrades and securing a new aggregates haul agreement, according to a news release.

The company said its affiliate, Central Texas and Colorado River Railway, will resume operations in April, moving unit trains of crushed stone from a San Saba quarry to a BNSF Railway interchange in Lometa, Texas.

The 49-mile line, idle since 2019, required extensive rehabilitation, including work on bridges and crossings over the Colorado and San Saba rivers to restore safe operations.

Local officials and shippers say the restart could boost regional economic activity by improving bulk transportation capacity while reducing truck congestion on area highways.

A Chinese electric truck startup is entering the U.S. heavy-duty market, with Windrose completing its first delivery of a Class 8 battery-electric tractor to a Texas logistics firm, according to Chinatrucks.org.

The truck, built on Windrose’s R700 platform, offers an estimated 400–450 miles of range and carries a price tag of about $285,000, roughly in line with the Tesla Semi.

Windrose is importing the vehicles from China despite steep U.S. tariffs — including duties as high as 100% on Chinese heavy trucks — which the company says are already factored into pricing.

The company, which has more than 100 trucks on order globally, is relying on Xos Trucks for distribution and service in the U.S., though it lacks the extensive dealer networks of incumbents like Volvo Trucks and Daimler Truck.
