When TeslAnt wrote in August that the EU was drafting local-content quotas for cars built in Europe, the article ended on what was missing: no threshold, no start date, and no answer on whether Europe could actually supply the parts. Two of those now have numbers, and they come from the carmakers' own lobby.
A study by the data analytics firm Mobility Global, commissioned by ACEA and published on 25 September 2026, finds that Europe's battery supply chain cannot meet the localisation requirements in the draft Industrial Accelerator Act. Around three million cars would fail to qualify if the Act takes effect in 2028.
What the Act would require
The Industrial Accelerator Act, proposed in March 2026, ties "Made in EU" status — and with it eligibility for public support and public procurement — to where a vehicle's components actually come from. The battery requirement arrives in two stages.
| Stage | Timing | EU-origin components required |
|---|---|---|
| Phase 1 | ~6 months after entry into force | 3, including battery cells |
| Phase 2 | ~3 years after adoption (2030–31) | 5, adding battery management systems and cathode active material |
The cell is in scope from day one. That is what makes this a manufacturing rule rather than a paperwork one, and it is the point Brussels was aiming at when the draft first surfaced: a rule that counts only final assembly is one a manufacturer can satisfy by unpacking crates.
The gap in European supply
European cell production is growing. It is not growing into this.
Capacity reaches roughly 306 GWh by 2032 on the study's projection, and in every scenario modelled, supply never catches demand. For medium and heavy commercial vehicles the mismatch is starkest — demand runs at about four times available European supply by 2032. The deficit in cathode and anode active materials, the Phase 2 components, does not close until somewhere between 2038 and 2040, and that is under the lower demand scenario.
The study's sharpest line is a caution about its own inputs: announced production capacity should not be treated as equivalent to operational capacity. Europe has a long list of announced cell plants, and several of them are stalled or unbuilt.
Where Tesla sits in this
Tesla is one of very few volume manufacturers already building electric cars in Europe, which sounds like an advantage and is not straightforwardly one. Model Y packs from Grünheide have run on cells sourced outside the EU — LFP from CATL in China, NCM from LG Energy Solution, and Tesla's own 4680s shipped from Texas. On a rule that counts cells rather than assembly addresses, a Berlin-built Model Y is less European than its number plate suggests.
What changes that is already under construction. Cell production at Grünheide is due to start in the first half of 2027, and in May Tesla more than doubled the target to 18 GWh a year of 4680s, taking investment in the unit towards €1 billion. Against a 2028 Phase 1 date, that timing stops looking like coincidence.
Phase 2 is the harder test, because it adds cathode active material. Tesla has just shown it can make its own — a Cybercab built from in-house cathode at Giga Texas. Texas is not the EU.
What is still undecided
This is a draft act and a lobby-commissioned study, and both facts matter. ACEA's members have an obvious interest in softer targets, and a projection to 2032 is a forecast rather than a measurement. The Act's thresholds are not adopted, and the 2028 start date that produces the three-million figure is a scenario, not a schedule.
The direction is not in dispute. Europe is writing rules that reward building cells here, at a moment when it does not build enough of them — and for a European buyer the practical question is which cars will still qualify for public incentives at the end of the decade.
