Although Jaguar has started teasing the new generation of XJ model before its introduction by the end of the year, it seems like engineers still got a lot to do as they are visiting Nurburgring very often recently! The car features a new style inspired by the XF which in comparison to the old XJ can be called revolutionary. The new Jag XJ shares many of its mechanical parts with the smaller XF as well.
So you get the new V8 engine with the XJ which means there will be a hot 500 hp model too. Ans you will also get the V6 diesel, while later on there will be a hybrid variant and a long wheelbase version.
