Ford’s Dagenham plant in Essex has built its 40 millionth engine.
Ford's plant, which has been manufacturing engines since 1931, now specialises in fuel-efficient diesel engines for Ford's small, medium and large car ranges, including the Fiesta and Focus, as well as for the US giant's commercial vehicles.
Over half of global Ford diesel engine demand is supplied by Dagenham.
Ford chairman Joe Greenwell said: "Dagenham producing 40 million engines is a significant milestone for Ford's biggest UK site.
"Ford Dagenham now produces Ford's most fuel-efficient engine in the 1.6-litre TDCi unit and exports to 12 countries around the world. This site is helping to power the UK's sustainable economic recovery."
