BMW has crossed a crucial industrial threshold at its Munich home plant. The carmaker has completed what it calls the ‘functional checks’ or ‘warm up’ of newly installed production equipment for the Neue Klasse, effectively dry-running the entire production process without vehicles or components.
For Munich, this milestone carries symbolic and strategic weight. The Bavarian capital is not just another BMW site; it is the company’s flagship factory and the centerpiece of a radical transition.
BMW has committed to fully electrifying the plant by the end of 2027, and the successful ‘warm-up’ of the Neue Klasse equipment shows that this transformation is no longer theoretical but is underway operationally.
New i3 ramp up in the summer
This warm-up phase confirms that automation, logistics systems, safety interfaces, and line coordination are functioning as designed. The next step is already scheduled.
From January 2026, BMW will move assembly of the next-generation i3 from its nearby Research and Innovation Center back into the Munich plant. That shift will allow BMW to test the complete production system – machines, workers, and quality processes – under real-world conditions ahead of series production.
The company has stated that volume production of the new i3 is planned to ramp up in summer 2026.
Munich’s timeline, however, only makes sense when viewed alongside BMW’s newest factory in Debrecen, Hungary. Debrecen is the first plant designed from the ground up for the Neue Klasse and plays a different role in BMW’s rollout strategy.
There, near-series test vehicles began rolling off the line as early as late 2024. Throughout 2025, the plant has been undergoing final commissioning and optimization, culminating in the start of series production of the new BMW iX3 in late October.
In other words, Debrecen goes first, followed by Munich. This sequencing is deliberate. Debrecen serves as BMW’s clean-sheet Neue Klasse factory, built entirely around digital planning, renewable energy use, and simplified EV-focused manufacturing.
Busy legacy plant
Munich, by contrast, presents a greater challenge: converting a busy legacy plant into a high-volume electric factory while maintaining ongoing production and retraining its workforce.
By mid-2026, BMW expects both sites to be producing Neue Klasse vehicles in parallel. Debrecen will anchor the first wave, while Munich will scale up as the leading German production hub for the new platform.
The transformation does not stop there. BMW has also confirmed that its plant in San Luis Potosí, Mexico, is scheduled to begin producing Neue Klasse models in 2027, extending the platform beyond Europe and reinforcing the group’s ‘local for local’ manufacturing strategy.
This timeline reveals how central the Neue Klasse is to BMW’s future. It is not simply a new EV model line but a reset of the company’s technology and cost base. Neue Klasse vehicles are built around BMW’s sixth-generation battery technology, with cylindrical cells, higher energy density, and a more integrated pack design.
The platform also introduces an 800-volt electrical architecture, promising faster charging and improved efficiency. Together, these changes aim to close the gap with fast-moving Chinese EV competitors while protecting margins in an increasingly price-sensitive market.
Serious commitment
Manufacturing is just as critical as product technology. By proving that both a greenfield site like Debrecen and a legacy flagship like Munich can be aligned to the same EV architecture, BMW is effectively future-proofing its European industrial footprint. The decision to make Munich fully electric by the end of 2027 underscores the seriousness of that commitment.
This industrial push comes at a politically ambiguous moment. The European Commission has recently proposed easing the strict interpretation of the 2035 ban on new combustion-engine cars, allowing limited continued sales of ICE or hybrid vehicles under certain conditions. For some manufacturers, this could be a reason to slow electrification plans.
BMW’s Munich timeline suggests the opposite logic. Factory conversions, battery supply chains, and platform rollouts operate on multi-year horizons that cannot be paused and restarted with every regulatory adjustment. If anything, regulatory uncertainty increases the value of efficient, flexible EV production that can compete on its own merits rather than relying on mandates.
