MK7 GTD - Real Life MPG

[Pob17]

Finally got my car on April 1st. Straight from the off mpg has been impressive. Daily commute is 140 mile round trip, about 80% motorway, remainder mix of A and B roads. Average over yesterday and today is approaching 52mpg, and I saw nearly 57mpg on way home tonight. Quite pleased with that.

What sort of temperatures are you getting these results in?

I think just as an important factor with the 57mpg result Pob got is that he does a 140 mile a day commute. If I did 70 miles on dual carriageway in one trip, doing 80mph all the way, i'd easily scrape 50mpg at 0-2C, and be pushing high 50s at around 8-10C. I regularly do a 75 mile round trip to see relatives, and was getting around 49mpg in freezing temps, and around 53mpg at an ambient temp of 8C.

Yep, I think it's the commute which is the reason. Last couple of days has been about 8 degrees in Lancashire dropping to about 4 degrees in Yorkshire. That was between 75 and 80 most of the way with some stop / start on the motorway. The non motorway bits are hilly so economy tends to dip then as you'd expect.

I managed to get 51.7mpg today on a 180 mile trip down south to visit family. That was sat at 80ish all the way. MPG was woeful until it warmed up though after about 70miles it really started to improve and then hung around high 40s to early 50s

That seems a bit low considering the length of the journey, if that's indicated rather than actual. I took the missus to work at 6:30 this morning, 16 mile round trip back home, 6C ambient temp, 80mph most of the way, indicated 52mpg, which will most likely be an actual 47mpg (considering the DTUK box takes the indicated/actual discrepancy from about 3% to 9%). If it's better than you're used to then I suppose it's a bonus.

That was indicated mate. My MPG seems very random. To work it will vary wildly from 49-57 and I can't even explain it. Can even get high 50s when the temp is low.

With a healthy 18C ambient temp today, I did a round trip of 29 miles to the Metrocentre, not sparing the horses on the A1, and did 52mpg indicated, which is a probable actual 47mpg given that the DTUK box makes the MFD overestimate by approx 9%. If i'd have taken it easy, i'm sure i'd have seen 55mpg indicated (50/51 actual). A TR GTD 5DR pulled up beside me on the A1 gave me a wave and went to speed off hard. Dropped to 4th and left him behind by quite a margin which demonstrated the difference the box has made. Then the missus was moaning about my speed.

16.5°degrees today in Sunderland and couldn't crack much over 40mpg. Only about 8 miles but still not good.

Quite happy with this today. 142 miles from Bicester in Oxfordshire to Cheshire on what was quite a busy and slow going at times journey. Had ACC set on the whole journey at 75mph, but a lot of the journey was sub 70 due to conjestion (and sometimes below 50mph). Ambient temps about 14 deg C.

Also, don't forget, mine is a DSG which is worse on fuel.

[Skinnee D]

A very decent result. I would doubt DSG has any penalty on a long run, unless its downshifting for harder acceleration with ACC on a more spirited setting. I've touched 60 mpg on long motorway runs a couple of times which also included a fair number of roadworks sections (or just mile after mile of cones...) restricted to 50.

What settings have you got on individual mode Andrew? Did you have the climate on during your journey? Chris

[Sootchucker]

Chris,

My "individual settings" are:

DCC: Comfort
Steering: Normal
Engine: Normal
ACC: Sport
Dynamic Bend Lighting: Sport
Air Conditioning: Normal

Yes climate was on for the whole journey @ approx 22°C (AC on). On the trip down to Bicester, is was less busy and so I managed to cruise pretty much at 75mph the whole way (no hold ups at all), and still got 56.7mpg.

For info, the car currently has 5,600 miles on it.
