Don't think this is an issue as the temp gauge is showing normal but I have been surprised how hot the Xj (5.0 litre na v8 model) engine gets. Is this just a feature of such a big and powerful engine!

I think it is just a characteristic of a big engine, Scott.  My 2.7 Diesel takes its time getting hot and then at the end of a journey takes its time getting cold.

 

The 2.7 Diesel engine [and presumably the 3.0 litre Diesel in the XF] has an auxiliary heater that warms up the cabin of the car which the engine is warming up.

Scott,

 

My XJ Supersport never used to get hot and that was a 5 litre V8 supercharged engine .

 

The XKR I have now has the same engine, but doesn't have a temperature gauge, so I don't know how hot it gets .

 

ATB,

Thanks folks. I don't think it is anything to worry about - maybe I should just be a tad more sparing on the dynamic mode!!!!!!!!
