To go supercharged or not...?
Discussion
I am looking to buy an X300 4.0. Seem to be strugging to find a good one, but have found one or two quite nice XJR6's. I wasn't originally looking for a supercharged one - I just want a wafter with leather etc, I understand the non charged 4.0's are capable of high 20's mpg on long journeys.
Unfortunately, much as the XJR's are quite appealing to me, I just worry I'd get irritated with the worse fuel economy. How much worse than the standard 4.0 are they? I'm not going to do a huge mileage, I have a TDi for daily use but don't want to find I avoid using the Jag if the MPG is down in the teens with even sensible driving. Are they as bad as V12's? I had one of those once, should I walk away and just get a 3.2....?

X300 3.2: 19.3 urban, 37.7 @ 56MPH, 31.1 @ 75 MPH
X300 4.0: 19.7 urban, 36.7 @56 MPH, 29.1 @75 MPH
X300 4.0 supercharged: 16.9 urban, 32.3 @56MPH, 26.4 @ 75 MPH.
General rule of thumb using the old measurement standard is to add all the figures together then divide by 4 to get an approximate real world figure in mixed trafic.
You'll find if you use the car for long distance touring you can usually improve the result by around 20%. Driven carefully but not slowly my X300 3.2 usually averaged somewhere between 24-27 MPG.

I've got an X308 (V8) XJR - a mate who had an X300 XJR tells me the consumption I get is similar to what he used to get in his.
I return about 15mpg average when doing lots of town & short (<10 mile) journeys mainly, but I had a run to Wiltshire the other day, and cruising sensibly on the motorways with the a/c off I got 28mpg for the whole trip - that was cruising at 70-80mph all the way.
Hope that helps & just get the XJR bought
