UK engine production rose 6.5% year on year in September with 224,917 units produced in the month. This was also the strongest month-on-month growth for exports this year, with overseas demand up 18.4% to 123,411 motors.
Overall engine output was down 1.9% on last year at 1,787,420, however.
SMMT chief executive Mike Hawes said: "Demand from overseas was particularly robust, with exports rising 18.4%. We welcome this growth and expect to see a continued rise in engine production in the UK for the rest of the year, reflecting the trend in the wider automotive manufacturing sector."
