MK7 GTD - Real Life MPG

[monkeyhanger]

OK so there is the answer,  I'd have guessed at 5mpg difference for both dsg and nineteens so that's about right.

Do 19s really make such a negative difference? I'm running my R on 19" Prets with sticky Michelin PSS tyres, and they're 10mm wider than the GTD/GTI option Santiagos. Running in Sport mode on my 20 mile each way clear commute and i'm seeing about 35mpg.

I do notice a significant difference running the aircon with or without recirculation - I leave it at 17C with the recirc on and it hardly makes a difference to mpg. Put it in LO without recirc and I drop at least 3mpg. The GTD used to have similar mpg penalties with aircon running in its least economic mode.

Well, it definitely makes a difference to the CO2 figures, which almost certainly is a MPG impact.

Just did a 500+ mile round trip from Cheshire to Essex over the last weekend for a wedding. 4 up in the car with a full boot. Hold ups at Leicester (M1) and M25 (both ways), and mostly sat on ACC at 70mph on the motorway (except the large 50mph zones on the M6 in Cheshire and the M1 near Luton) but overall got this (see below).

Bear in mind that the car has only 3000 miles on it and it is DSG not manual and I am also running the 19" Santiagos. Can't complain really. Filled it up this morning and manually calculated it at a true 54.77 (43.24 litres - second click @ £1.109 per litre)



as an aside, it's interesting that the mobile phone camera captured the infrared sensors of the motion sensor bar on the head unit (never noticed that before  )

That is impressive. Very impressive.

Mind you, the longer the trip, the more likely you are to get good MPG.

Biggest killer is getting the thing up to an efficient temperature.

Travelled down from North West to Kent Tues, but filled up at Shell Crewe J16, M6 on the way down.

My 'long term' is 39.7 mpg over about 2k miles.

^ That is abysmal for such a long journey in a GTD. Whag was your cruising speed and was there much traffic?

Lets just say I wasn't hanging about 

Had a run in with a 15 plate Focus ST on the Autobahn, I mean M6 Toll, GTD come out top...

Was thinking that myself - must have been caning it at around 90mph or had a horrendous journey to get that sort of figure as an average ?

If you look a couple of posts above your, I did a similar journey last weekend (from Cheshire to Essex), in my 19" Santiago and DSG equipped GTD (with 4 adults up and luggage) and averaged 55mpg when the cruise was set at 70mph - methinks you have been enjoying yourself

I could never manage to get above 45 on a run in my gtd and that was driving very sensibly. Did show 75mpg once coming down hill on the isle of Skye haha

There was quite a few 50mph zones, in these I set my ACC to 55mph (which in reality is about 51/52?) I find I still get cars flying past me in these average speed zones - how do they get away with it?

But yes I like to enjoy the GTD  :roll eyes: Really actually must try sometime to get a good mpg, I just get baited too many times by the likes of 118d's.. still think the TR attracts too much unwanted attention.
