Data shows that 161,490 cars left British factories last month, compared to 169,247 in November 2016 – down 4.6%.
Domestic demand declined from 33,745 in November last year to 24,276 last month – down 28.1%.
Meanwhile, exports rose from 135,502 in November 2016 to 137,214 in November this year – up 1.3%.
Year-to-date figures show that more than 1.5 million cars have rolled off production lines, with nearly eight out of 10 destined for one of 160 global markets. While export volumes remain stable, production for the home market is down 9.0%, resulting in overall output falling by 2.0% since January.
SMMT chief Mike Hawes said: “Brexit uncertainty, coupled with confusion over diesel taxation and air quality plans, continues to impact domestic demand for new cars and, with it, production output. Whilst it is good to see exports grow in November, this only reinforces how overseas demand remains the driving force for UK car manufacturing. Clarity on the nature of our future overseas trading relationships, including details on transition arrangements with the EU, is vital for future growth and success.”
However, additional findings from the SMMT show that British engine manufacturing grew in November.
Data shows growth of 11.4% last month to 279,532 units compared to the 250,879 in November 2016.
Both domestic and export demand were up, by 20.8% and 4.0% respectively.
Meanwhile, year-to-date figures show more than 2.5 million engines have rolled off UK production lines so far – up 6.6%.
Hawes added: “This year has been a very robust year for UK engine manufacturing, with huge investments into new facilities and engine models delivering impressive dividends both at home and overseas. To attract future investment and ensure continued global success, government must safeguard the business conditions we currently enjoy and provide clarity on our future trading relationships with the EU and other key markets.”
