A no-deal Brexit is 'not an option' for the UK motor industry and must be ruled out now to avoid damaging one of the EU's most valuable economic assets.
That's the stark warning from the Society of Motor Manufacturers and Traders on Wednesday morning, which said resulting tariffs on cars alone would add £5billion to the collective EU and UK auto trade bill.
It would also make models imported into the UK £1,500 more expensive to buy on average.
A delegation from the industry body is due to meet representatives from EU countries in Brussels on Wednesday to emphasise the importance of securing a deal for the sector that doesn't 'undermine its ability to operate'.
The UK's motor industry said the sector could be hit with tariffs of 10 per cent under World Trade Organisation rules.
If these increases were passed directly on to consumers, import tariffs would push up the cost of UK-built cars sold in the EU by an average of £2,700 - a hammer-blow for demand, the SMMT said.
