The Jaguar Land Rover plant in Halewood, Merseyside, has moved to 24-hour production for the first time in its history.
An extra shift was brought in after the car-maker, owned by Indian group Tata Motors, created another 1,000 jobs to meet demand for its Evoque and Freelander models.
Staff will now work a night shift as part of a three-shift pattern. The new jobs, which were revealed in March, take the site's workforce to 4,500 - three times the number that were working there three years ago.
Jaguar Land Rover's human resources director Des Thurlby said: "These 1,000 new jobs are further evidence of JLR's clear ambition for continued growth. We are moving Halewood to three shifts and 24-hour operation to meet increased global demand for our products.
"JLR's supply chain is also set to benefit, with thousands more jobs expected to be created. Our commitment to expand the Halewood workforce and increase production is great news for JLR, for Merseyside and for the wider UK economy."
When the move was initially announced, Business Secretary Vince Cable said it was "further evidence of the strength of the UK automotive sector".
