The car maker scotched rumours that it was planning to pull out of its product development centre in Whitley as it released initial drawings of how the new site could look.
The 3,000-hectare development, which will be built on land next door, will serve as a centre for automotive excellence, Jaguar said yesterday.
A completion date and the number of jobs to be created has not yet been set.
Jaguar, which axed 1,150 jobs when it decided to end car production at Coventry's Browns Lane plant, said the development showed it was still committed to the city.
Ken McConomy, corporate affairs manager at Jaguar, says: "The vision is that the site will attract a number of suppliers, who specialise in automotive design and technology. We want it to be a hot bed for science and technology. We want it to attract people at the leading edge of design."
