UK car manufacturing rose by 10.7% in August and is up 4.4% over the first eight months of 2011.
Commercial vehicle production output also rose by 9.3% in August, but remains down 4% year-to-date.
UK engine production rose by 14.4% in August and is up 4.8% over the January-August period.
Paul Everitt, Society of Motor Manufacturers and Traders, said: "A manufacturing-led recovery is taking shape with August’s automotive output up more than 10% and a recent wave of private investment securing long-term growth for the UK sector.
"We are on target to exceed 2010 production volumes this year, with more growth to come in 2012. Government must continue to encourage and incentivise private sector investment in R&D, skills and capital equipment to maintain momentum and deliver lasting opportunities for the UK supply base."
