Average MPG - Longterm - GTI

[pauliem]

Manual or DSG Paul?

Manual with Performance Pack.  Drove this morning up to Tamworth - approx 190 miles.  Managed 41.5mpg.  The car was extremely heavily laden though, well over 100Kg in the back.  So could have probably got a touch more.

Turning of the ACC and using the speed limiter seems to be the key to getting the high figures.

I would agree with this statement. ACC seems to worsen MPG, especially when the road you are driving on is not perfectly flat.

I don't use ACC, I don't have auto climate control on, I have tried driving in Eco mode where it automatically puts the car in neutral and coasts when your foot is off the pedal. I've tried not exceeding 60mph, I've kept the car in auto mode on ECO where it's obsessed with labouring the engine all the time by driving in a gear that's far too high for the speed and I've never seen past 35MPG. Even when doing all this at the same time and having an horrendous driving experience feeling like I might aswell be in an Up! (no offence to Up owners, it's a cracking car).

The car is a thirsty monster that has drank it's way through over 4 full tanks of fuel over 1100 miles. I only commute 150 miles a week to work and back and I'm spending around 250 a month on fuelling the thing!

I'm not happy really. Corgi is getting more MPG out of his Porsche! Coming home tonight I managed a whopping 25 mpg, not even toeing it :/

MrSavage: forget eco, makes for an awful driving experience and you have to put your foot down harder to get anything out. Sport is my most economical mode (albeit in a GTD). My mpg seemed to shoot up 10% on the turn of 1870ish miles/3000km (so far, been benefitting for about 150 miles) - ECU built in long term running in function that happens in stages perhaps?

Yeah you're probably right to be honest. I'll give it a test and see how it is. Surely the car is run in well before 1870 miles though? I would have thought 1000 miles is overkill even. So you have everything set to sport in your GTD?

You're in a manual right?

Just done a 120 m round trip into north wales mixture of dual carriage way A roads and country lanes  averaged 41.6 mpg  , used sport mode some of the time rest was normal mode

I drive mine in either normal or sport mode. I think Eco mode actually makes it worse as the throttle response is so numb.

I have just passed the 3500 mile mark. The engine feels looser, more powerful and better on fuel. The latter is most surprising considering the much colder weather conditions compared to September when i picked it up.

Are you driving DSG GTI7? That is very interesting to know. Crazy that the car is so long fully bedding in!

Physio that's very impressive. I think on a long, clear run I could possibly achieve somewhere close to those figures. The GTI seems to get better and better on economy the longer the drive is.

No it's a manual Savage. Earlier in this thread i posted a picture of a run of over 48mpg. But this was really really trying hard and cruising at around 60 on the motorway just to find out what it could really do.

Manual GTD in Sport (Normal is thirstier!). I wonder if VW have been tinkering with running in programs for a while. My last car was a Scirocco 170TDI and it felt like a 140 until it hit 340 miles/500Km and it was like a switch had been flicked to give it 20% more power. Never had anything like that happen with the other TDIs. Over the last week my 42mpg GTD has become a 48mpg GTD (hoping it's not a blip with the unseasonably mild temperatures).

Like you I have left the ACC alone and haven't really used the aircon. Babying these engines do them no favours, not saying thrash a cold engine, but giving them a little bit of a workout early into the trip gets the car up to temp quicker. Definitely find that driving the GTD a bit harder has had no detrimental effect to my mpg.
