The ACEA Position Paper on Brexit highlights the significant contribution of the EU automotive industry to the EU economy, with 12.6 million jobs and 7% of GDP. The paper emphasizes the close integration of the UK and EU automotive industries from an economic, regulatory, and technical perspective. The European Single Market has enabled the industry to strategically set up its business operations, with 300 plants across the continent and a high level of integration in supply chains, production sites, and distribution networks. The paper also highlights the importance of the trade in automotive parts, with the UK importing 78.8% of its total part and accessory imports from the EU27. The paper concludes that Brexit will have significant implications for the EU automotive industry, and it calls for a transition period to minimize the negative impact on the industry and its workers.
