What kind of mileage are you guys seeing in your XFs? This is what mine is normally in the 5.0 NA V8; Pirelli all season tires and a K&N drop-in filter are all I've done. I can get higher and I can certainly get lower, but this is typical.

 

 

My travel is almost all stop & go for shorter distances. I'm happy to average 18 mpg. So, I'm jealous.

XF 5.0L NA

 

My XFR gets an easy 28mpg if I set the cruise @ 75mph, a slower run of 40/60mph It'll pull 32mpg

 

an XFR gets that good of mileage? Isn't that a supercharged 5l??

Jaguar's MPG estimates for these things are way off then. Best I ever got was 28 and that was a mostly flat highway over like 200 miles.

 

Yeah don't get me wrong, average MPG is much nearer book figures, but on them sorta roads at them speeds that's what a reset over 20/40 miles or so reads.
Your 28 sounds about the same as mine will do over 200 miles.

 

I just wrapped up a 1400+km (~875miles) round trip, where I averaged 9.0L/100kms (26.1mpg), and I definitely wasn't baying it.
The drive involved a lot of twisty stuff, so speed up, slow down, and on the long straights, I averaged ~130kph (~81mph), and this was with a fully loaded car, with 4 people, and luggage for a weekend away.

Truly amazing the fuel economy you can get out these things, especially when they're equipped with the 8 speed autos. I saw fuel economy drop down to as low as 8.0l/100kms (~29.4mpg), but that just wasn't fun enough for me

 

I get about 12-15 mpg in the start stop city driving. Highway driving, I can typically get 25-27 mpg US Gallon. 5.0 NA.

 

I average 22.3 MPG according to the dash, but I get 100 smiles per gallon which is what i care about!

 

My best mileage for 150miles journey was 7.9l/100km (36MPG) and this was actual numbers- filled tank before and after that to check if trip computer is fine.
my worst MPG but best SPG on 12 miles journey was 8MPG. This is for XF 4.2 Supercharged.

 

Low 30's for my XFR, although I did drive between two local towns and got just over 35 mpg last week at 53 MPH. Those are UK MPG figures. I know the USA has a different size Gallon to us.

 

i've kept track since buying new in 2012 and i've never done better than about 22 mpg and that's usually 80% freeway driving.

 

I think you need to post your average speed as well as mileage because it makes a big difference sitting in traffic. Even makes a difference if you live ten minutes from work like I do or commute an hour each way. I just checked and last tank showed 17.4 mpg and an average speed of 23 mph. That was all city driving and getting stuck in traffic jams a few times.

 

Cold starts kill the MPG for the first 15 minutes of driving especially under 50mph.

 

Maybe at a later date somebody (me) can remake or restructure this thread. It should be expected that more cruising speed will do better then lots of stopping and going as far as miles per gallon go.
