BMW is preparing for a worse-case Brexit where the UK quits entirely the EU’s customs union and the single European market. The automaker’s priority is to ensure that its Mini, Rolls-Royce, engine and stamping factories in England receive parts on time despite potential bottlenecks at the border. BMW’s purchasing chief, Markus Duesmann, discussed Brexit implications with Burkhard Riering, editor of Automobilwoche, Automotive News Europe’s sister publication.
