Cars being made in the UK are using more British parts, according to new figures from the Automotive Council.
Some 44 per cent of all components used by UK car makers now come from domestic suppliers, compared to 41 per cent in 2015, when the last study was carried out. In 2011, local content was just 36 per cent.
British car manufacturing raced to a 17-year high last year, with more than 1.7m vehicles made and since 2009, when the Automotive Council was formed, production has risen more than 72 per cent.
Regarding output of the UK automotive parts sector, turnover has increased from £9bn at the start of 2011 to £12.7bn today marking a 41 per cent rise.
The chief executive of the society for motor manufacturers and traders (SMMT) Mike Hawes, said the domestic supply chain was "the backbone of UK automotive and its health is crucial to the success of the whole sector".
He added that while the news was positive "the process takes considerable time" and the long-term competitiveness of the UK needed to be maintained.
The car industry has flagged its concerns over Brexit, with negotiations getting underway yesterday, notably the risks of failing to secure a tariff-free deal.
More than half of the 1.7m cars produced each year in the UK are exported to Europe and the industry wants its positive relationship with Europe to continue so products and parts can flow freely.
Business secretary Greg Clark, said:
Through our modern industrial strategy, we will build on our strengths in the automotive sector in R&D, creating skilled jobs and further extending our supply chain. The government is committed to maintaining the international competitiveness of the UK automotive sector.
