This exclusive spy picture shows the upcoming Jaguar XJ testing this week.
The latest shot was captured by an Autocar reader, who spotted three XJs testing in convoy near sister company Land Rover's Gaydon HQ.
The heavy rear disguise, as seen in the photo, covers up very radical rear styling treatment that will make the new XJ the most striking-looking executive saloon when sales start at the year’s end.
Its public debut will come a few months earlier at a glitzy London launch on 9 July.
Both short and long-wheelbase versions wil be launched together. Power will come from a twin-turbo 3.0-litre diesel and 510bhp supercharged 5.0-litre V8.
Jag has also confirmed that the new car will be launched in both short and long wheelbase versions.
All models are likely to be highly specified and customers will be able to tailor spec and options more than on previous Jags. The new XJ also comes with a panoramic glass roof.
