MK7 GTD - Real Life MPG

[C2K]

Think it would help focus these posts a little if people specified transmission, total mileage and then MPG.

64 is good stuff.

It seems that from February 2014 any car that was originally fitted with a DPF will now fail the MOT if it is removed.

Managed to average 63.1mpg on way to work this morning. mostly congested motorway, but just shows what it can do.

I got 58mpg this morning on my 40 mile commute of unclassified and B roads. Thought that is pretty good considering I have DSG, overtook everything that got in my way so anything doing less than 60 and I only passed the 1000 mile mark today.

But of course. Ask yourself though, how a hollowed out, mapped out DPF looks any different.

Most tuning groups do it this way, common on Renaultsport DCi Meganes for instance.

Had no real opportunity to put my foot down on the way to work today and managed 48.3mpg (5C ambient temp). Great, but if I drove that way every day, the exhaust wouldn't get hot enough to passively regen, so that figure would soon take a large dive.

well driving like miss daisy last night to Chichester and back, i managed an average of 41.0mpg there and 45.1 back. (Going 60-70 on ACC a lot of the time) about 17-20miles each way.

Really not getting great figures despite being in eco or normal..... hmmmmmmmmm

I leave it in Individual with everything set to Sport, apart from Eco for AC and ACC. Also I only use the AC for occasional defrost etc. Long term average 52mpg actual.  Manual transmission; 2600m clocked up so far - mix of long distance and local commuting.  High 50's on some steady longer runs.  Computer only seems about 1mpg optimistic based on recent refils.  Happy with that considering the performance.

I've now just crossed 2500 miles and my long term average is 47.1 mpg. Now when you consider that about 2000 miles of this is just my commuting to work and back (circa 10-12 miles depending on traffic), I'm pretty pleased with that.

Going home from work last night was a particularly good run (without the major hold ups I normally get for the first mile), and I averaged over the 15 miles journey home 57.6 mpg (at an ambient of 6.5°C).

I've tried pretty much all of the driving styles, (Comfort, Normal, ECO, Sport and Individual), and have settled on Comfort for the best overall compromise. Unlike some others, I haven't found driving in ECO, has a negative impact on fuel economy, just no better than Normal or Comfort on my car, and with the added loss that in ECO you loose the nice cornering light function of the headlights for some strange reason ?

It does seem that the more miles the car gets, the better it feels, and I can't wait for the warmer weather in the Spring / Summer when I think 60mpg + should be achievable for the same journeys. To be honest, as it currently stands, if I take the Urban published figure (49.6) then I'm achieving about 95% of that figure or if I take the Combined figure (60.1) I'm getting about 79% of that figure, but that's probably not too comparable as most of my journeys are urban from cold starts each time.

From my experience (also recently crossed 2500 miles), Normal is the thirstiest mode (for my style of driving at least), but it seems to have more clout through the upper gears than Sport, which has more lower end clout. Ideally I’d like to stay in Sport 90% of the time and for those times I put my foot down in 4th/5th/6th, I wish the car would chuck it in normal for the brief spell of acceleration.

Unless you have a DSG to take advantage of the freewheeling option, I’d forget Eco mode, does nothing for my economy at all.

I think VW missed a trick with the accuracy of the MFD mpg display. They always used to be 9% optimistic, now they’re 2-4% optimistic. If my 46mpg (indicated) was reading 49mpg for an actual 45mpg, as it would have done in the Scirocco, then I probably wouldn’t have thought I was doing so bad for this time of the year. Just wondering why VW tightened up their MFD mpg accuracy so much when the car would have seemed closer to published figures by leaving it alone – tighter laws brought in maybe?

For those that don’t have ACC/DCC fitted to have a “cComfort” setting – I’m assuming Comfort (apart from the softer damping of the active suspension) has all of the engine settings of “Normal”.

As per Skinnee D, I also set everything within individual to Sport except the aircon which is set to Eco. I don’t routinely use the active cruise control, no real point on my commute – moost benefit to the motorway milers/longer journeys.

Probably because they can through more accurate metering of fuel required to meet the emissions regs... Previously, the metering, certainly on diesels, was less accurate so they had to give themselves a margin for error... I suspect that it is a side-effect of that...
