Average MPG - Longterm - GTI

[Mr Savage]

Well I tried leaving it in sport and using paddle shifters on manual and managed 31 on my commute today, not groundbreaking but 6mpg more than normal. The DSG box is useless at changing gears by itself. It makes the car gutless.

Typical acceleration in drive mode (with sport driver profile), it changes;

2nd at 10mph (fine)
3rd at 20mph (too early)
4th at 27mph (far too early)
5th at 35 mph (engine now has no power at all)
6th at 40mph (useless)

Every gear change labours the engine so much, is this changeable with a DSG software update because I feel really disappointed that I have to drive my DSG in manual all the time!

Got these stats today:



Pretty good really.  This was ECO Mode, Air-con off, making lots of use of the speed limiter.  Don't think I could get it much better than this to be honest.

[Mr Savage]

I can only dream of those figures. You must have been driving like miss daisy! What do you mean by making use of the speed limiter? Does the manual also Coast when you take your foot off the accelerator?

[pauliem]

I really wasn't driving that slowly to be honest.  Steady, definitely not urgently. The trick is to try and maintain a constant speed.  Acceleration is what causes the MPG to drop, not perpetual motion.

Speed Limiter:

Press the mode button on the ACC control and the display will change to "Speed Limiter"





The little plus and minus buttons either side of the ACC distance control push the speed limiter up or down in 5mph increments.

I does feel like it is coasting, and the MPG figures would certainly suggest that it is, but I don't see how it could possibly do that in a manual car.  So I guess it does not.

Using the limiter as opposed to the ACC is far more efficient.

I believe the advertised MPG figures ARE attainable, i think that it will just take some time for the engine to settle in nicely and for us lot to learn how to drive them properly (for good MPG).

Here is a recent run from Preston to Manchester, i admit i was trying to get the best possible MPG whilst driving in eco mode...

My best was 47mpg, wouldn't want to do that again, but yes, it is achievable.

Normal driving, the odd bit of fun here and there.... 36.1 mpg.
The mpg readings seem pretty accurate to me, not the 6 -10% exaggeration of the mk6.

The mk6 would be showing 39.6.......

(and 53.3 for GTI7me's pic)

Paul, call me insane but the speed limiter simply stops your speed going over a set limit right? IE, setting it to 60 stops me going over 60. I'm struggling to understand how that improves MPG as you are of course well aware of what speed you're actually doing.

In regards to the coasting, you're right it can't do it in a manual I guess. Never thought of that. Strange then that the manual is on paper more economical than a DSG when it has this excellent fuel saving extra that manual doesn't?

How come your range shows so many miles? I'm sure mine shows 300 on a full tank. Isit cleverly based on your average MPG now?

[GolfTi]

400 per tank is easy, normal driving.

11 x 36 is 396,so average for me.

I do get the odd 20mpg trip though, normally on a Sunday...

The ACC does reduce mpg as it applies the brakes sooner than you normally would and it can't use other signals such as brake lights and the indicator of a car that is about to pull in front of you. Brilliant system though.

Limiting the speed means you can maintain a constant speed without little blips of acceleration that you inevitably do when you are on manual control. Try it out next time you take the car out. You will see the mpg shoot up as soon as you reach the limited speed.

The tank shows a long range based the the mpg. That figure was even having already driven about 150 miles.

400 miles out of a tank is not easy. I'm getting around 200 out a tank and have only seen over 35MPG once! It must be DSG that's shocking on the fuel then.

I'll give it a go on my next commute, thanks Paul. Haha, I'll take a photo of my range next time I fill up the tank. I think it shows 270 miles on a full tank!
