Real world MPG 2.0TDI

[Steve Hut]

Mine is 6 months old and just been service at 18000miles and getting mid 40s normally on a motorway run, got 38mpg on motorway last night. Best it did was 52mpg but that was sitting at 60mph. Twenty mile trip to work returns 40 mpg. Love the car otherwise. Could just keep it and when its bought and paid for dont have to worry about fuel consumption as much then as outgoings for the car will be less.

New Skoda Superb is looking tempting though????

My "Real" world figures are around 38mpg stop / start and around town and usually achieve around mid 40's on the motorway when driving normally.........I did a test though for fuel economy as posted in another thread ....see below



Ok, so for those that have heard me saying I have an 80 litre tank in the past.....forget that, it turns out I DO NOT!!

Ask me how I know?...lol

I actually ended up calling Audi and asking them to re confirm exactly what size tank I have....( I'm almost postive the salesman told me 80 litres......anyway, they're adamant its 70 litres ) so hopefully thats put that to bed.

How do I know?
Well carrying on from the rest of my tank I decided to run it all through today to see what I could get.

Having managed 750 miles previously and working on approx calculations from before I was estimating I had x amount and could go
for so many miles....lol
It was soooo lucky I was just literally pulling into the garage forecourt as she started to splutter and cough a little!!

From yesterday 537 miles and there was 205 miles left showing on the DIS when I checked before I started, so I thought lets see........

I really started to drive extra carefully, nearly all motorway, so some 50mph limits, 60mph and 70 mph limits.....I drove anywhere between 58mph - 65mph when I could, usually NOT using cruise control although I did at certain points.

She started off at around 34mpg and quickly started to rise and got up to the 50.4mpg mark fairly quickly, at this point the miles to empty had increased to 255.

I made a conscious decision NOT to use Cruise control and instead when there was a downwards incline I slowly stepped on the gas a little increasing speed by as much as 5 - 10 mph.....similarly when travelling up hill I eased off the gas and reduced speed by anwhere between 5- 10 mph.

At times this worked so well I thought I was never going to finish the tank of fuel....lol

Here's some of the milestones I saw......All of them new for me at least!!

Couldn't believe I actually saw 60mpg!!




The I saw 61.3mpg.....No pic
couldn't believe it?

Later as the tank was running through I saw this.....62.6mpg



Getting close to the end and after probably 80 miles or so this popped up on the dash....
64.1mpg....amazing for me as I've never ever got anywhere near that before....




My DIS2 which I use as for the lifetime of the vehicle and never ever reset it, has jumped from 37.1 up to 38.mpg average

End of the run showed the following figures.....795.5 miles travelled



In conclusion, I reckon that if starting from a very strong point as regards mpg and you drive conservatively, almost hypermiling at times that in excess of 900+ miles would be achievable....

However, it was only an exercise as far as I'm concerned and not one that I intend to repeat again anytime soon.

I swear I could actually count the blades of grass as I went by it seemed so slow at times, generally, I like to bury the foot into the carpet now and again. I may drive sensibly as far as economy goes from time to time and will be keeping an eye on my mpg ( makes sense due to the cost of fuel these days ) but I'll just be driving normally as a general rule

Getting mid 50's on a motorway run, mid 40's on stop start urban runs. Thats in a manual.

Offset pedals are a pain though!

If it makes you all feel better i'm getting 30 at best in the BiTDI. But to be fair its not the car you buy for the purpose of economy.

If this makes you feel better, my BiTDi:

First 1000 miles 38.2mpg - taking things easy
next 1000 36.1mpg - booting it a lot more
next 1000 38.4mpg - engine getting looser
next 1000 40.4mpg - hurrah!
Current 500 miles since last reset 42.7mpg - did a run to Leeds and back!

On the run up to Leeds I managed over 50mpg taking it steady 75 on the motorway. I destroyed that on the way back overtaking on the A roads - like you do.

It's variable based on journey distance and ambient temperature, my Fiat Panda does the short journeys currently averaging 56.2!!!

[Passatier3]

Not that much better! I put my foot down on the way home and only got around 42! I've bought a Fiat Stilo diesel as a work hack and runabout and that's doing around 53 so between them not too bad! Plan is to use the A6 to commute a couple of days each week and the Stilo the rest of the time and for general running around which the A6 is overkill for.

[Garnet19]

57.2 mpg nice,,, my suspicions are that the computer readout is not correct. It looks like I will have to do it the old fashioned way, fill the tank and calculate. I wont have it I'm only doing 40mpg.

[Wuffles]

That would make it a different readout between the manual and the multitronic then? I would be surprised if the display software between the two were different.

[Garnet19]

Well hope your wrong, hear is the link for todays drive home, My 2012 Audi A6tdi Auto Multitronic Trip Home - YouTube

[Passatier3]

Garnet19 - had a look at the vid and given the type of journey reckon that the consumption is about right. You need to be cruising along at about 60 in top gear (pseudo top gear) for a good few miles to achieve anything like a half-decent fuel consumption figure. You seem to be doing quite a bit of stop/start and not going over 40mph. How far is the journey? From cold, a bit of stop/start for the first couple of miles and then fast A roads, after about 8 miles I'm up to an average of between 38 and 40 and after another 12 miles it's around 44. My Passat DSG was less affected by slower, stop/start driving - I reckon that it's the nature of the Multitronic that when going slowly and accelerating that it's quite an inefficient drivetrain when compared with a DSG or manual.

[Garnet19]

oh my god, your not supposed to say that's normal. My 15 year old A4 1.9tdi Avant would be up to 60mpg even from cold. I only do 6 mile to work so no chance of getting it warmed up.
