Best MPG You've Had?

So today I had a really relaxing drive. It averaged at 48 miles per hour and achieved 47mpg (UK MPG) In a 25t Ingenium.

I have also had 46mpg over an 80 mile drive through the welsh mountain roads and shropshire roads just keeping up with the usual traffic and having a bit of fun whenever I got the space ahead of me.

What have you achieved with what engines? :D

I have averaged 55mpg since late August. This is average over 18 mile journeys on a regular basis and a 140 each way journey up the A9 and A roads from Fife to Elgin. I do from time to time give it head and enjoy the torque available. I am very impressed with the consumption overall and can average 60+ on a motorway without trying. Love my Jag.

I've managed over 40mpg on about half a dozen journeys - usually busy but moving motorway trips, and I usually get mid-thirties on more normal out of town runs, along with mid-twenties on short urban trips.

It's pretty much what I expected from the 300ps petrol beastie, and it is actually rather better than most of the petrol motors I've owned before :eek: so I'm not complaining!

I have a portfolio 180D, had it for 90 weeks now and over that period have averaged 40mpg. Top was on a 105 mile motorway trip to London, averaged 70.1mpg.
Call me sad...... but I am retired, love my XE and love playing with figures in spreadsheets, see the attached. Maybe surprised to see that 87% of my journeys are 0-5 miles. Over the 90 week period I have covered around 12,300 miles

According to my eco data thing, the "best" trip is 75mpg @ 99%. I don't think I was driving it that day.

77.1 from Scotch Corner to Chesterfield on A1M, M18, M1, A617 and 99.9 from local garden centre into town (about 2 miles)

Anyone checked indicated - v - actual mpg (using full to full tank or similar)
My experience with previous cars (not Jaguar) suggested around 10% exaggeration despite odometer checking out close to 100% accuracy.
In my humble experience the discrepancy of indicated to actual is or can be way more than 10%. I am currently averaging around 43-44mpg actual on a tank to tank basis. I must however say that most of my journeys are less than 30 miles, and a mix of A road and a little town work. This is with a 180D R sport.

I'm averaging about 34mpg over last 18 months, that's using tank to tank.
On a long journey I often get 47-50.
This is with the 25t.

I've recently purchased an XE S and I'm currently on 19 MPG :D although being a new owner I've done a fair amount of spirited driving. Will be interesting to see the comparison when the I get some longer journeys under my belt.

XE R-dynamic P300 - 28mpg (although it's only a week old and ive only done 790 miles, so it's not bedded in yet)
I-Pace EV400 - 99999999999999999.9mpg :p
So you now have both?
About time for some photos of your new XE and the electric job.
The gallery is being ignored a bit somewhat for new deliveries.
:D

I do a lot of short journeys and my average is about 36mpg. On a decent run the car will return high 40's - low 50's. My best ever was 65.1mpg over a fairly short 8 mile run, mainly on duel carriageway. All in all, i'm pretty pleased for a car with 240bhp on tap.

Yep finally! Took delivery of the I-pace a few weeks ago, the XE last weekend (after a 5 month wait). Both are at the detailers for a long weekend, picking them up tomorrow and he should hopefully have done some photos :)

Might be a silly question, but for those getting good MPG in the V6, are you guys using manual gear changes? Appreciate the better MPG will be cruising on a motorway, but around town I notice sometimes the auto sits in a lower gear than it seems to need.

Or am I just struggling to adjust to the auto?

Best I have had is an indicated 51.1mpg, that was a 137 mile run at average speed of 63mph (mostly motorway). Car is a 20T petrol with the Ford engine. Normal running about 36 to 45 mpg, dependant on distances.
Must say this is the best car I have ever owned regarding the fuel consumption and performance. My previous X Type diesel auto only managed about 49 mpg on a long run and about 37 in normal driving

yeah, I've got 43-ish on a motorway run, I get the better mpg's when in 'ECO' mode - I let the car choose the best optimum revs vs gear and it does a better job than me! The car can feel a bit sluggish in this mode but when I want a quicker getaway I just use the paddle and drop it down and I'm away - over the hills and far away.... la la...la

Yep as UV Blue says, Eco mode and let the car do the rest. I think with 450 nM of torque you dont need to rev much to make progress.

This rainy morning on a 30 miles trip to my working place I had about 54 mpg, backing home it was about 38 mpg . My tank to tank average was about 42 mpg for the first 1800 miles. For the past 3000 miles the trip computer shows 45 mpg. Best mpg? 3.2 l/km, one mile trip, downhills in summer.

Fair enough, I'll give Eco mode a bit more of a chance then. Thanks

Best I've had from the V6 is an indicated 43mpg, 100 mile motorway drive on a Sunday evening. Same weekend saw less than 23mpg hooning around in Wales.
23, you can't of been trying hard enough, I managed to get mine down to 12 :shock:
