The company says the new model, which will go on sale next spring, is the most advanced Jaguar ever built.
The flagship saloon, which will be built at Jaguar's factory in Coventry, will receive its world debut at the Paris Motor Show later this month.
It will make its first public appearance in the UK at the International Motorshow in Birmingham in October.
More than 800,000 XJs have been sold since the first model was introduced in 1968, accounting for more than half of all Jaguars made.
