The next-generation Jaguar XF and XJ saloons are already under development, the brand's design boss has revealed.

Design director Ian Callum says work on the next-generation XF and XJ saloons is well under way, telling Autocar UK: “I’m designing the next XF and thinking about the next XJ".

Jaguar’s new rival for the BMW 5-series, the XF is likely to arrive in 2016, before the new XJ. Expect an evolved look of today’s car, with some of the family traits of the F-type and C-X17 concept making it on to the model.

Callum believes that the current XF, introduced globally in 2008 and heavily facelifted in 2011, has aged very well. “I’m a huge fan of the XF, and I believe it has stood the test of time. The sales figures are increasing all the time, too.”

The next-generation XJ is further off, with the current car yet to undergo a facelift. However, that will happen next year, when the luxury saloon is given a light nip and tuck which will include minor detail changes to the front and rear end styling. There is no word on any dynamic or specification changes.
