Just wanted to get your views of honest "real-world" mpg predictions for the Mk7 GTI.
The official combined mpg figures are as follows:
Manual GTI 47.1mpg
Manual GTI Performance Pack 47.1 mpg
DSG GTI 44.1mpg
DSG GTI Performance Pack 44.1 mpg
What do you honestly think the combined mpg of the the GTI will be with a variety of driving styles (i.e. Motorway, A Roads, B Roads and a bit of a hooligan blast every now and again)?
For example my current cars claimed mpg is 44.8. But after 4 yrs of driving the "actual" figure is 37 mpg. So that's nearly 8 mpg down on what they say it should do. Gets you thinking.
-
I'm expecting around 25mpg, most of my driving is short journeys and I plan to use the whole rev range whenever possible. :evil:
I expect 35-40mpg on a careful longer run.
-
You can use this site to find your figures if you don't know them:
http://www.carsite.co.uk/car-data/mpg
Scroll down and do "MPG search for used cars"
Here are my official figures:
EMISSIONS & FUEL ECONOMY
Urban MPG: 35.7 mpg
Extra Urban MPG: 60.1 mpg
Combined MPG: 47.9 mpg
What I actually get in the real world:
Combined MPG: 38.0 mpg
So I'm about 10mpg down on the supposed combined MPG. To be honest the official figures are a pile of sh!te for my car. I once spend about an hour trying to optimise my MPG by varying my speed until I found the sweet spot. I managed to squeeze 50mpg out of it. That is still 10mpg down on the officially achievable value!
I've also found it makes relatively little difference whether I drive like a saint or throw it around like a madman. Even pushing the car to the limit gets me 38mpg. Being sensible... hard to say but 40mpg is probably tops. The 50 I got was late at night on a straight open road which went on for about 60miles and I could just sit there and focus everything on slight throttle variations while watching that MPG counter. Could never repeat this if I had to use the brakes for roundabouts or lights or other drivers...
Now, being a :nerd: I would love to do, and will be doing, a study into the mpg I can get using a specific fuel, likely Tesco 99 when my GTI arrives. If anyone wants to join in and stick to a specific fuel and track their figures that would be awesome! When the darn thing arrives I'll post up what my plans are.
-
In general I find I get 10mpg less than the manufacturers stated amount.
-
If the reports of the bad mpg with the 150 TDI engines are anything to go by, it will be much worse than expected. I know when I test drove one for a very short period at actually quite slow speeds it rose to 30, a small blat in 3rd ramped it back down to low 20s.
-
Try coasting. Seriously. It makes quite a big difference with modern engines. Obviously no use on most motorways but works quite well on undulating A and B roads. I can get a 5-6 mpg difference when I can be arsed to use this method.
-
I expect an average of somewhere in the mid - high 30's based on my driving and current figures.
-
Couldn't give a hoot personally.
-
My current Scirocco is quoted at 37 combined and I obtain 32. With the GTI being quotes at 47 I'd like to see 40 and I think it will be doable..
-
This will be a sticky in the TDI section when it starts up.
-
A4 sline 2.0 TSI... I used to do a little dance when I got it to 34 mpg! :huh:
-
Easier to get to or near combined figures in a TDI than a TSI. Should expect about 36-38mpg on a GTI most of the time and 42mpg on a long journey if you're quite sensible.
I'm getting around 53mpg around the doors right now, 56-60mpg capable on the motorway doing 75-80mph. Best I had was a 350 mile trip on a very hot day with the aircon maintaining 18C all the way down - 61mpg.
I do wonder whether active ADC will really cock economy up for everyone by constantly braking to maintain distance between you and the car in front to what it considers to be "safe". If I can permanently turn it off then I probably will. I'll be pissed off if the realworld MK7 figs don't surpass my Scirocco, seeing as it has no bluemotion tech on it at all.
-
It depends of cause on your driving style and road conditions but maybe a 10% gain over a mk6 from the short drive ive had in one. VW clain 18% but thats in their lab.. So maybe 36 it may even get back to the mk1 level of 38...

..
I'm wondering about VWs new 18-20% gains over the engines, there doesn't appear to have been huge leaps and bounds in engine efficiency, it seems like they are attributing most of it to the eco tech and a little to revised integrated manifolds that enable the engine to warm up quicker. I'm pretty sceptical myself, given the poor economy reported for the GT 150TDI and ACT 1.4TSI, actual economy seems no better than the previous versions.
-
With these turbo engines it really does depend on the types of road you drive on and your driving style ... so everyone will get different mpg. From my experience I'd expect something like this as real world mpg with the new GTi
- short trips & town driving will be very poor (mid 20's)
- high speed Autobahn cruising in Germany :wink: will be around 30 (could be better if the gearing in 6th is longer on the Mk 7 ?)
- more gentle A road cruising at 50-60mph should be high 30's.
-

Maybe those poor mpg stats are because those cars aren't fully run I yet? Hope so :rolleyes:
-
I couldn't care less what mine will be as long as it's better than 35mpg I get out of the tiguan at the minute!

Never had appreciably better economy after run in on my last 6 TDIs (it varies between summer and winter but not between years of ownership for the same period) . The old "VWs aren't run in until they've done 50k miles" seems to be a bit of a myth, these days at least with tighter engineered tolerances. I do think that ones the rings are properly seated, a modern VAG engine is run in.
-
Not that bothered personally but I know some of you are.
38.1 long term after 4k.

Cheers fella. That's music to my ears that is. My current Scirocco's lifetime average is 37.7 mpg. So, the prospect of similar mpg but with way more horses is encouraging.
Ooh wait at min, your's is a manual and mine will be DSG... So I can't expect 38 mpg then can I :cry:
-
Depends a lot how you drive it though. GolfTi might be doing more around town than you.
-
Just done a 1500 mile round trip to Berlin, 4 people, full of luggage and packed roof box.
High speed too. (Apart from the 2 hr Autobahn closure when the Germans came over to talk to me about the GTI).

Bodes well for us DSGers, i'm not overly fussy but equally it does matter to me that i'm getting the best from the car when required ie on long motorway journeys, i've said before if i get simlar mpg from the mk7 dsg that i do from my manual mk6 i'll be very happy taking into account the start/stop etc.

Stop start depends a lot on how long you stop and for how long. Audi brochures claim up to 3% saving (presumably for worst case city driving). If the stop-start is coming on a lot for you, you'll not really be in a position to be getting great mpg anyway. It annoys the hell out of my dad, and will probably do the same for me. If I can permanently switch it off with VCDS then I will, rather than remembering to switch it off every journey. It can never anticipate whether you are literally going to be stopped for 2 - 10 seconds, or 1 minute, and when it cuts out when you are literally about to move off again, then it is annoying.
If you expect 40mpg with a manual and 36mpg on a DSG driving reasonably economically most of the time then you'll not be disappointed. You can see from the CO2 values that the DSG will be 10% thirstier than the manual.

as far as im aware it can be turned off permanently via a menu on the touch screen. Personally im gonna try it out but pretty sure i'll be turning it off after a few days
-
Just got to judge how long your going to be stopped for. If you get stopped behind a car but can see that the traffic in front is moving on then just keep your foot on the clutch. It's no big deal really.
-
My only previous experience with stop/start has been in a Ford. As CraigW said- if you see traffic starting to move don't let the engine stop. It only stops when you put the gear in neutral and take your foot off the clutch. As soon as you press the clutch the car starts again. Never had a problem with it. Don't know how DSG works though...

It's true that the DSG is more thirsty than the manual but the mk7 figures for both are around 10% better than the mk6 which is why i'm hoping they'll cancel each other out if that makes sense??

Last Sunday I took a very leisurely spin in mine, Sunday driving style, rural roads, mostly 45-60mph in 6th gear. Over 100 miles I averaged 43.5mpg. Pretty decent.
That figure drops considerably once I hit stop/start traffic or I drive the car like it should be driven :smiley:

If I averaged anything over 40 I would be over the moon with the mk7, I've only ever got 37 mpg on my mk5

Yeah but like I said, I've found that I'll only get those figures if I drive very leisurely. 30-35 is more realistic if you "drive on".

Yeah that mpg figure I quoted is on cruise control on the motorway at about 80 mph on the speedo :)

Even though I'm not getting a dual clutch anymore I don't the gap with the manual really is 10%. The manual figures assume optimum shifting times and realistically no ne ever is. DSG will always be the same though so you can expect to achieve the DSG figures (all else equal). So manual may be better, but probably not that much better. 5% maybe.

CO2 output is analogous with fuel consumption, and even the official fuel consumption figures show a 9.4% disparity. Assuming reality varies from book figures at the same % for both manual and DSG given the same driving style then you'll still see the same disparity.
DSG rarely drives economically - it is either shifting up way too early in an attempt to be economical, or if you put your foot down a bit it hangs on to gears a lot longer than I would with a manual, taking it near the red line - it doesn't have much middle ground for medium acceleration. You also have a lack of engine braking such as when you might take your foot off the gas early when approaching a roundabout and brake later - making the most of your momentum etc.
The DSG version of my Scirocco is geared a little lower than my manual one - i'd expect the MK7 Golf to be the same for all variants. The top speed on the DSG is lower than the manual (albeit negligibly) which seems to suggest it geared lower or has to work a little harder (and use more fuel) to do whatever the manual does.
-
You are assuming the guy with the DSG car has the worst possible situation while the guy with the manual car has the best possible situation. People just don't make optimum shifts with a manual box, so the results you get with a manual will be lower than the published figures. The DSG will shift exactly the same in tests or in the real world so it will not have this penalty.
Beyond this both will suffer in various ways but I'm just saying when you keep quoting the 10% figure you are assuming the manual driver always makes a perfect shift. They do not, ergo the gap is less than 10%.

Well i've had a MK5 Golf 170 TDI, and i've also had a lend of my dads for a few weeks when he was on holiday and mine was in for some serious warranty work - same car but he had DSG and I had manual. 50mpg on mine and 45mpg on his. Same driver, same driving style (as much as the DSG will let you be the same), 10% difference in fuel economy. Maybe if the manual driver has the perfect shift then it could be more than 10%. The manual Golfs and Scirocco since MY2011 have had economy gear change prompts, and when i'm in an economically minded mood it pretty much agrees with what I am doing (hence no prompts).
I know my car well enough that under gentle acceleration, unless i'm getting a regen, it will suggest I change up to 3rd at 18mph, 4th at 24mph, 5th at 30mph and 6th at 40mph, and correspondingly it asks me to shift down if I go at less than these speeds in said gear. If i'm not driving it gently, I will change up at a speed that will ensure that I will hit the next gear at not less than 1900rpm, to keep the turbo happy.
Maybe we forget these things once we get used to DSG and the car is doing all of our gear change thinking for us, but a manual driven well will surpass a 6 speed DSG in economy by quite a margin unless you are permanently sat in 6th and cruising.
This is because there are more than 2 situations for considering gear changes, and DSG only seems to consider 2 scenarios (extremely early change up under very light acceleration or have the gearbox knock down a cog or 2 and have the car run to the red line under anything under light acceleration). There are times when you put your foot down moderately in the same gear because for the situation you want might only require a little spurt of acceleration and it's not worth knocking down a gear.
Lower gear ratios on the DSG don't help the situation either. It's 6th gear is like "5.8" when you compare it to a manual - that will always cost you more fuel.
Not an issue with the 7 speed DSG or 8 speed BMW auto box - the auto is more economical than the manual in that situation, more gears to choose from and higher top gear ratio.
There are plenty of situations when the DSG doesn't make the perfect shift because it doesn't know what you want to do next (such as anticipating a maneuvre that may see you stay in a gear a few seconds toavoid the DSG shifting up and then back down again), it best guesses with the amount of throttle you are giving at any given time.
DSG will give you an easy drag race from the lights, but on the economy side, for any given driver and their style it is on a downer. Experience and VW figures reflect that.
-
As I haven't actually driven the DSG I bow to your experience here!
-
My mk5 GTI, and both my mk6 GTI's were not too far off official mpg when driven Republican.
-
As I haven't actually driven the DSG I bow to your experience here!
I don't suppose many people drive both manual and auto variants of the same car, and they'll only be bothered what their car is doing, no matter which one they get.

Quick update. 1000 miles covered now. Average mpg is 38mpg. In my last tank I did 410 miles of mixed driving with at least 70/80 of them attacking b-roads. I'm very impressed especially as the tank is only 50l compared to 55. The range showed 20 miles so that shows 450 miles is well do-able when engine beds in more. No that is my only post regarding mpg as I usually never care about mpg in a GTI !! The things I do for you guys :laugh: :laugh:

I've only done about 160 miles but my trip details showed 400 miles total potential of what has been mixed driving with a reasonable amount of motorway driving. Very impressed, although after showing off in it tonight to my mate, that average MPG will have dropped some! :grin: Like you though, I tend not to monitor it as it is what it is and you accept that when you buy the car.
-
400 from the last few fill ups.
That's 20 better with 5l a smaller tank.
:cool:
-
Just done shy of 1000 miles now and averaging 33.2mpg which is okay, not great but not terrible. Certainly better than my TT where I was getting approx 29mpg so an improvement for me in that respect
