MK7 GTD - Real Life MPG

[mike_f]

I have only got about 300 on it just now so I guess if it loosens up it might improve. Reading back through this the improvements seem huge over the first 1000 miles.


Totally love the car, surprised at how quick it is, thats coming from having an S3 before too - still fun to drive

I've now hit 1000 miles and economy seems to be improving.

Last week I did a 230 mile trip and averaged 51.5mpg.  I did the same trip a couple of days ago and did 55.1mpg 

This was mostly motorway from Surrey up the M1 towards Leeds, similar traffic, weather conditions and speed (75-80 on the motorway).

The previous trip was on a 50/50 mix of BP Ultimate / supermarket fuel.  The latest one on a full tank of BP Ultimate.  I've run BP Ultimate in previous cars and seen improvements in smoothness and responsive but never a noticeable benefit to economy.  So I'm assuming the improved mpg is just down to the engine loosening up.

Must say as the mileage increase so does my daily mpg that I'm seeing.

Replacement of my first full tankful of fuel today. At 515 miles in I covered 414.5 miles with 9.77 gallons of V-Power diesel, which is 42.4mpg vs indicated 46.5mpg since fill up. My MFD is reading 9% optimistic.

I'm pretty disappointed in this TBH, seeing as I would have probably only gotten 40mpg using a lesser fuel with more regens happening as a result. Comparatively driving far more carefully than caning my 170TDI Scirocco (bereft of any eco tech) and still getting 50mpg indicated/45mpg actual without using V-Power. If I drove my GTD like the Roc, i'd probably be around 37mpg actual.

I have noticed that on many occasions, the gear change suggestions have me driving in a lower gear than would have been normal for the Roc at the given speed, yet the 2 cars seem to be geared pretty much the same. Managed a paltry 43mpg (indicated) on my commute to work today. Will be hoping to crack 50mpg indicated when I shoot through to Hartlepool this weekend or I will be really disappointed.

Speaking to my dad last night, his GTD has now racked up 6k miles and is averaging 49mpg indicated/47mpg actual (his MFD seems more accurate than mine), still well down on his MK5 170TDI.

Turn climate control off

Climate is off. It's set up for eco on the cooling, but I rarely have the aircon on - it's probably been on all of 2 hours in the time I had the car, and those were at motorway speeds. haven't been using the cruise control either.

I think you can only get decent mpg if you keep it to a max of 2k revs

My mpg has taken a turn for the worse with ambient temp falling to 10C on the way to work and 14C on the way back.

For my last 5 commute trips of 12 miles each (3 x to work, 2 x back) I haven't cracked 43mpg indicated, which is probably 39mpg actual. My journeys have been clutter free, so it's not down to traffic etc. By the time the trip mpg has reached 40mpg in the GTD, I would've been at 48-50mpg in the Scirocco.

On my commute, gains over 40mpg seem to be very slow to where it finishes at the end of my journey. This is despite the car warming up a bit quicker, being a tiny bit lighter than the Scirocco and having eco tech the Scirocco doesn't have. I also used to have quite a heavy right foot in the Scirocco that my GTD hasn't really experienced much yet. Fuel economy above 60mph seems sh!te on the GTD. Do 70 or 80mph cruising speed and my mpg suffers greatly compared to previous high output 2.0TDI engines.

MH. Same thing for me x I don't use the ac and if required its on Eco mode. God knows what is going on I have emailed the dealer as I am due there on sat  may just revert to standard shell. And fill up v power once in a while to assist with the regen/cleaning.

My brim-to-brim mpg so far -

1st tank: 47.9 (48 indicated, 50/50 BP Ultimate, supermarket fuel)
2nd tank: 48.8 (50.4 indicated, 100% BP Ultimate)

These both include a daily 7 miles stop/start commute in heavy traffic around Leeds and a trip down the M1 towards Surrey.

On the journey back south last night I managed an indicated 55mpg in reasonable traffic.
