Vauxhall's Ellesmere Port plant will build a new generation of Astra cars in an "historic" deal that will see it produce at least 160,000 cars a year.
About 700 jobs will be created at the plant, which employs 2,100, plus thousands more in the supply chain.
Owner General Motors announced it will invest £125m in the factory and spend about £1bn in the UK component sector.
