According to the Society of Motor Manufacturers and Traders (SMMT), production increased by 9.1% compared to the same month last year.
To date in 2014, output in Britain’s automotive sector has shot up by 12% to hit 1,132,727 units, spurred on by demand both at home and abroad.
Production for the domestic market increased by 6.2% last month to 27,804, while export volumes grew to 81,200.
In the year-to-date, more than 877,523 cars have been built for international customers - 13.3% more than in the same period last year, which the SMMT said demonstrated the ongoing international appeal of British-built vehicles.
Mike Hawes, SMMT chief executive, welcomed the figures, but said it would be important for investment in the sector to continue to ensure future success.
He said: “August's strong performance is good news for car makers and welcome news for the UK economy, which depends on this thriving sector for an increasing share of UK exports.
“British car producers are exporting a diverse range of high quality, attractive new models that are in demand across the world thanks to multi billion pound investments made in UK plants over the past few years.
“Future success depends on continued investment in plant and products, and that in turn depends on the UK maintaining internationally competitive business and trading conditions.”
The motoring sector has been especially productive in 2016. In July, the industry built 1,023,723 cars – the first time the one-million milestone was reached in July since 2004.
In April it was revealed that a car was built every 16 seconds in the UK, with more than 159,000 cars rolling off production lines in March – the highest figure for 12 years.
Commenting on the August figures, Industry and Climate Change Minister Nick Hurd said: “With the Paris Motor Show taking place next week, today's figures are a powerful reminder of the strength of our automotive sector and the demand for British-made cars like the new Honda Civic, which is about to be exported across the globe.
“The automotive sector now accounts for a bigger share of our exports than ever before, and we will support this success by investing in innovation and continuing to give workers the skills they need to succeed.”
