UK car manufacturing fell 6.7% in October to 150,060 units, leaving year-to-date volumes flat (down 0.3%).
The Society of Motor Manufacturers and Traders said global economic uncertainty is affecting demand, but the outlook is still positive with all-time record production levels expected within the next few years.
Around 80% of UK-built cars are exported, with the diverse product mix giving a 50/50 split between EU and non-EU exports.
However production for the home market has increased by 10,000 units or 3.8% this year to 281,788 cars.
"The UK’s car manufacturing industry is still in a strong position in spite of the growing uncertainty surrounding the global economy," said Mike Hawes, SMMT chief executive.
"Billions of pounds have been invested into UK facilities in the past two years, with several new models starting production this year and more in the pipeline. There is still demand for UK-built products given their reputation for quality, design and engineering excellence."
