BMW Confirms Mexico Will Build Neue Klasse i3 and iX3 From 2027

Electrive's reporting frames this as BMW reaffirming a plan that had faced some uncertainty given tariff volatility between the US and Mexico: production of Neue Klasse i3 and iX3 models in San Luis Potosi remains on track for a 2027 start, not delayed or reduced in scope. That confirmation matters because Mexico is BMW's only Neue Klasse production site in the Americas, making it the anchor for how the platform reaches North American customers.

TechTimes' coverage adds a specific milestone: iX3 production out of the Mexico plant is expected around August 2027, with the i3 sedan following after BMW's Munich plant begins Neue Klasse i3 output first. That sequencing suggests BMW is staging its global rollout by model and region rather than launching every Neue Klasse variant everywhere simultaneously.

The headline figures are substantial for a single-plant expansion: more than 110,000 square meters of additional plant space tied to an EUR 800 million investment, plus a standalone battery assembly center exceeding 80,000 square meters backed by more than EUR 500 million specifically for Gen6 battery pack production. Together, that puts BMW's combined San Luis Potosi commitment north of EUR 1.3 billion once vehicle assembly and battery investment are counted together.

Building Gen6 battery assembly locally in Mexico, rather than shipping packs from Europe or Asia, is a meaningful supply-chain decision. It shortens logistics for North American-bound vehicles and gives BMW more direct exposure to USMCA content rules, which matters both for cost and for how vehicles get classified under regional trade agreements.

San Luis Potosi is one of four plants worldwide building Neue Klasse vehicles, joining Debrecen in Hungary, Munich in Germany, and Shenyang in China. On the battery side, it is one of five global sites producing BMW's Gen6 battery technology, reflecting how central this next-generation battery chemistry and packaging approach is to BMW's broader EV strategy, not just to Mexico specifically.

For US shoppers, the practical takeaway is that a future Neue Klasse i3 or iX3 sold domestically could plausibly be sourced from more than one plant depending on timing and trim, though Mexico is expected to be the primary Americas-facing site given its geography and the scale of investment BMW just confirmed.

Here is the complication US buyers should not ignore: under current Section 232 tariff treatment, vehicles built in Mexico face a 25 percent tariff entering the US, compared with roughly 15 percent for vehicles built in Germany. That gap exists even though Mexico is a USMCA partner, reflecting how Section 232 national-security tariff authority operates somewhat separately from broader USMCA trade rules, which were themselves under a joint review process as of July 2026.

If that tariff differential persists unchanged by the time Mexico-built Neue Klasse vehicles are ready for the US market in 2027, it could meaningfully affect landed cost and therefore MSRP or lease pricing for iX3 and i3 variants sourced from San Luis Potosi versus any German-built alternative BMW might offer for the same nameplate. BMW has not detailed how it plans to price around this exposure, and the USMCA review itself could still change the underlying tariff picture before 2027 production ramps up.

If you are the kind of shopper already tracking Neue Klasse launches for a 2027 or 2028 lease, the Section 232 gap between Mexico-built (25 percent) and Germany-built (roughly 15 percent) tariff treatment is worth asking your dealer about directly once order guides open. A 10-point tariff swing on an imported vehicle can show up in cap cost, and by extension in your monthly payment, even before any options or destination charges are added.

Because this is a multi-plant global launch, do not assume every Neue Klasse i3 or iX3 sold in the US comes from the same factory. Ask specifically where your build's VIN is sourced, since plant of origin can affect both tariff treatment and, potentially, initial build-quality expectations for a brand-new platform ramping up in more than one country at once.
