Stellantis and Renault have publicly backed the UK car industry for inclusion in the EU's proposed Industrial Accelerator Act (IAA), the "Made in Europe" legislation that would tie EV subsidies and government procurement to European-origin manufacturing. The catch: both executives made clear that British inclusion comes with a condition — London must restrict Chinese car imports, something it has so far declined to do. The IAA is the EU's second major protectionist move against Chinese automotive competition, arriving alongside Monday's confirmation of a quota limiting Chinese hybrid imports to 350,000 vehicles per year, expected to halve China's current 6% EU market share. The legislation would require cars to contain sufficient European parts and materials to qualify for EV grants and public procurement contracts. If "European" is defined strictly as EU-27, Britain is out. Emanuele Cappellano, head of Stellantis's European brands, said the UK should be "equalised to the EU 27," citing historical ties and existing manufacturing footprint — Stellantis operates a van factory at Ellesmere Port. But he was equally blunt about the trade-off: "It's very difficult to defend industrial footprint and at the same time let the market completely open to import. Either one or the other." Renault CEO François Provost echoed the framing, saying there was "no other choice" but a deal, while adding: "If the UK is willing to join the European ecosystem, this is to have an industrial ambition." The lobbying coalition is substantial. ACEA and Clepa, Europe's two main automotive industry groups, have also backed UK inclusion. Against them stands a counter-argument rooted in political logic: France's industry minister had argued Britain should be excluded precisely because it chose Brexit. The fight is now a negotiation over the definition of a single word — "European" — with billions in subsidies and procurement contracts at stake. For the UK, this creates a genuine policy dilemma. Business Secretary Jonathan Reynolds confirmed this month that London's refusal to impose Chinese tariffs is "under review," but the UK has benefited from cheaper Chinese EV imports and has no domestic EV manufacturer competing at scale with BYD or MG. Joining the IAA framework means choosing European industrial solidarity over consumer pricing and trade flexibility. Cappellano also pushed for a 2030 deadline extension for European battery sourcing requirements, acknowledging China's dominance in battery supply chains. He expressed scepticism about extending the "European" definition beyond the EU and UK to include Japan, Turkey, or Morocco, pointing to existing proposals allowing 30% of materials to be sourced externally. The details matter enormously: every percentage point of local-content requirement reshapes supply chains worth tens of billions. The deeper pattern is unmistakable. Europe's auto industry, facing lower post-pandemic demand and the enormous capital costs of the EV transition, is building a protectionist architecture that treats market access as a bargaining chip. The UK is being offered re-entry to an industrial bloc it voted to leave — at a price set by Paris and Brussels, not London.
