So after only seeing 13mpg in town (I wonder why?) -- I finally took the RS out on a cruise and was pleasantly surprised with the following:

MPG: 25.5
Avg Speed: 63.6
Distance: 313 miles

I was *never* seeing this mileage on my old 4 cyl turbo...I suspect if I had kept the 120mph "passing" to a minimum it would have increased.

Anyone else have some mpg on their XF to report in?

 

Avrg 18.4 in my XFR........

mostly short 30-40 mile round trip journeys........

 

24-26 mpg highway at 60 plus mpg steady is about what I achieve in my 470hp supercharged. Around town half of that. The juice is worth the squeeze though.......

 

Between 18-24 depending on season in my 4.2 NA

 

25-26 with 5.0 NA on the road. 30 with my 04 XJ on the road. Miss that car!

 

on my 2012 with the 5.0 N.A. i get 13-15 in the city and 23-24 on the highway. frankly that's my only complaint with the car; crappy mpg.

 

UCLA…..ditto !! And I have an 09 XF-SC !!

 

Daily driving in Houston traffic 18 on the highway 25 is easy

 

Daily driving in Pittsburgh area, I get 18-19 with my 2009 XF 4.2 liter 300 HP non supercharged. On long trips in relatively flat country ( like Ohio, Indiana, Nebraska, Oklahoma etc.) get 30 mpg! 26-28 in hilly highway driving - like Pennsylvania, West Virginia, Virginia.

 

Range 340mi.

 

Lifetime to date on XFR-S is 13 L/100 km = 18.1 mpg, mostly highway and backroads driving, very little in town.

Lifetime on old XFR was 13.6 L/100 km = 17.3 mpg, same driving as above.

Numbers calculated from fuel pump readings and distance driven.
