I use the A2 for my 70 mile round trip commute. 80% motorway 75 mph and 20 town driving and I get 53 ish. With a very light foot and sub 60mph the best I got on the commute to work was 69.8 mpg (to be precise!)

Personally I think the economy of the A2 Tdi is over-egged. You can get silly mpg from most diesels if you drice them slowly enough!

The A2 seems to excel on B roads ambling along. In the summer when I first bought the car I drove with a very light foot from Fishguard to St Davids and the mpg was climbing past 74mpg by the time I got there. After that I thought sod it and enjoyed the nice twisting undulating road on the return trip. It really does handle well with the sports suspension and 17" wheels!

But real world driving doesn't seem to give anywhere near Audi's claim of 66mpg average.

I had a hire car last week - a Peugoet 407 136ps diesel, a big car, and making no attempt to drice economically (in fact booting it on several occassions) it still averaged 53 mpg over 200 miles!

I have had my TDI 90 for just uder a year too. In that time I have covered 7780 miles and my average mpg is 48.2. The best I've had on a tank is 52.2 mpg and the worst 42.7 (these figures calculated the old fashioned way, not using the on board computer which I find to be about 6% optimistic).
Have to admit I'm dissapointed by the economy given the official figures. Wouldn't say I have a heavy right foot - I try to be as smooth as possible. Most of my miles are on the motorway where I tend to drive at 80-85mph where conditions allow. Overall though, I still love the A2.

I get around 45 miles to the gallon out of my 1,4 petrol A2 well pleased with its fuel consumption. I do tend to drive at 55 mph and get into 5th gear by the time I am doing 45mph. I do trips round the town and longish trips to work every day. If I do a very long trip say 200 miles I get nearly 50 miles to the gallon. This is by far the best car I have driven for fuel ecomomy

Most of my driving is on B (country roads) with very little traffic so i don't have to keep up with other cars. but the cold weather and Air Con on to get it warm does kill the MPG. Also i only use shell fuel as i found the Tesco stuff wasn't giving me the same MPG. Eventhough i think its only the additives that are different.

crb1011

06-02-2006, 11:42 PM

Emm at last someone who has found that supermarket fuel gives less to the gallon. I have been saying this for years but nobody where I work believes me. My lad uses super unleaded fuel and he finds he can get an extra 2 days driving from his tank. Thats approx 100 miles but I am yet to use it as I think it may affect the engine management

Emm

07-02-2006, 12:04 AM

I used to work for tesco years ago and the fuel is picked up at the same Depots. I believe (though i may be wrong) a Tesco lorry pulls in and gets fuel then a Shell lorry pulls in and gets fuel, but its the additives that make the difference, eventhough we are only talking 1 litre of additive to 4000 or 6000 compartment load of fuel, each lorry holds 4 or 6 compartments and then it depends on diesel storage. (this is all from memory) don't qoute me on these figures, i left Tesco years ago

I do think the major super store fuel is ok but just not as good as Shell. i don't seem to get the same pick up or economy

94 k miles in my Silver Open Sky 1.4 TDI SE @ 58 mpg cumulative average, 09/01 to 09/5 - min av journey 35 miles, mainly Mway/A class roads, cruise 80 mph. Oil cons typically 1 ltr/7 k miles, service interval prompt always ran past 30 k. Full ASH Car for sale!

12 k miles in my new Black 1.2 TDI Tiptronic @ 87.8 mpg cumulative average, 09/05 to date - journey types as above, cruise 75 mph. NB: DIS set to instantaneous mpg definitely influences driving style and resultant fuel burn! Oil cons tbc - nil to date and still on dip stick. Service interval prompt currently suggests first due @32k

I get anything between 52 and 56mpg on average (worked out properly) from my TDI 75.

It's a little less than I was hoping for as my old Punto JTD managed 55mpg and was quicker too. However, I am hoping the economy will improve slightly as the Punto did about 50mpg when I bought it (with 20,000 miles on the clock) and the economy didn't improve to 55mpg until about 30,000 miles were under it's wheels; diesels can take a while to 'bed-in'.

My cousin's fiancee reckons they get 600 miles out of a tank on their TDI 90, but I think he is talking out of his 'arris ;)

07-02-2006, 10:49 AM

I have a TDi Sport and I average 49mpg most of the week as my drive to work is only about 3 miles. I have tried it out on long runs and it works out to be 62mpg! The official figures are always a little on the optimistic side for all cars, don't know why they bother really, especially when you drive like I do!!!!

Have any of you looked at your average speed? Mine over 3 years has always hovered around 28mph. See, not as mad as you think I am Dad....

mlarner

07-02-2006, 11:40 AM

I believe one of the main reasons for the "optimistic" official figures is that the tests are simulations done on rolling roads with no wind resistance etc. This is done to enable a standardised test to be used.

48mpg out of our 90ps TDi.
Includes motorway and town. Never seems to change.

75TDI
Average journey about 7 miles to and from work. Partner occasionally does 70 mile round trip to Brighton or some such - not M-way.

Average mpg (brimmed tank method) 51mpg unless Auxilliary heater is in use then 46-48mpg.
Partner once got over 60mpg on a M-way run to Heathrow on the M25.

Usually 55mpg round town in summer driving like a nun I achieved 62mpg again round town mainly in the rush hour (and the kids were in school)
I have achieved the dizzy heights of 60mpg with a roof box all the camping gear for 2 weeks and full passenger load coming back from the Vendee to Stockport some 500mile (chanel not included)

TDi 75, only 6000 miles old. Almost all commuting into London from Surrey: 20 miles at "quite high" motorway speed, 12 miles in stop-start traffic. Average 51 mpg (measured properly).

For a given journey the A2 uses almost exactly half as much fuel as does the RS4. Which is pretty poor considering it only has 20% of the power ;-).

Cheers, Richard.

08-02-2006, 12:33 PM

TDi (90) averaged 60-65 mpg on my 45 mile commute to work 90% motorway. Using Shell Diesel Extra gave me about 3 mpg more.

08-02-2006, 01:33 PM

i have seen 80mpg out of my 1.4 petrol on the way back from scotland but that was at 50-60mph as we had a ladie defender in our convoy, usually i get exactly 200miles out of a tank and she only drinks bp ultimate i like to think this partly accounts for why it is 110hp, i think AMD's fettling may have helped though :)

Paul Dennis

08-02-2006, 10:16 PM

I can't speak from a lot of experience since I've had my A2 (05) for just a few weeks. However, I have kept a record of miles covered and fuel used. The car has still only just done 7000 miles. I refuelled after my first 500 miles, still the tank low warning light had not come on and I put 33L in (BP stabdard diesel). The second refuel came at 480 miles, no warning light and 32L. I reckon this works out at about 68 mpg. The last fill was with BP Optimax and my impression is that I'm getting slightly better mpg (160 miles covered at 3/4 tank as opposed to 140 miles).

I have a relatively easy commute, 25 miles each way on A and B roads with a little stop-start driving thrown in. I 've had a 120 mile A road and motorway trip to London (70-80 mph cruising) plus London traffic driving and several trips with three adults in the car.

I try and drive smoothly but not excessively slow and have the impression were I to really concentrate then 70 plus mpg would be relatively easy in the 1.4Tdi. All in I'm pretty amazed by the effortless economy of the A2. We also have a Skoda Octavia 1.9 Tdi and this gives 52-55 mpg without much effort.

GrayB, driving like a nun with a police car glued to my tail, seriously it only really involved changing up before the turbo kicks in around 1800rpm, accelerating gently and looking well ahead to ease off rather than brake, you would be surprised how little you need brakes when you try this.
Thats where I'm going wrong then. I tend to drive between 1600 and 2400rpm. I feel it vibrates a bit too much below 1500rpm...

ULP

Thats where I'm going wrong then. I tend to drive between 1600 and 2400rpm. I feel it vibrates a bit too much below 1500rpm...

Below about 1500rpm the engine is labouring too much, even on a light throttle. Driving like this will save a few quid in fuel, but this will be decimated when the big-end throws a wobbly as it shatters to bits. Labouring an engine at low revs is not a good thing to do.

I keep between 1500 and 3000rpm in normal driving, although 4400rpm has been seen on occassions...

GrayB

09-02-2006, 04:35 PM

That's what it feels like to me, too! Besides, it's such a willing little thing that it's hard to refrain from letting the turbo-torque do it's thing....

13-02-2006, 01:19 AM

Over the last 8234 miles I've averaged 61 mpg (1.4 TDi 75) doing mostly A roads and some motorway. A2 is 04 plate and now 20K miles.

I oftern find I'm only doing 65 mph on motorways as I find that to go faster means putting the foot down (used to habitually do 80 mph in previous 1.8 petrol Cavalier but only got 35 mpg). I think I've sub-consciously set myself a target not to get less than 60 mpg and hoping for 65 mpg!

I see the remarks about not driving less that 1500 rpm. Hmm, arround town I tend to drive at about 1100 rpm in 4th or 5th - I think that gives 30 mph. Any other persons thoughts about this?

Edit: that was guess work. Had a quick drive today and I see the first speedo mark after 1,000 is 1200 and it's only happy in the lower gears at that revs. Did drive for a bit in 4th at 1200 at 30 mph but not conclusive - too much traffic to look at the speedo too much!

I just dont think our car sounds or feels comfortable doing that - perhaps with the exception of running down a gentle incline.

tdiman

13-02-2006, 01:16 PM

Well just shuttling round town mine is quite happy in fifth, although I have found the speedo to be well out so really I'm driving around 35 on your MPH which is 30 of real MPH (GPS confirmed) I never let the engine struggle and change down when I need to. It could be that I have a smoother running engine for some reason, I have used other A2tdi's and found they were not as happy.

Dev

15-02-2006, 09:45 PM

I have a 1.4 TDi 2001 X reg that I had from new. Most of my driving is on a long single carriageway A road (60 limit) to and from work. Typically I get upper 60s. The best I've had is 71 mpg, about 420 miles for a tankful. Consumption is worse when the weather is cold. It seems to like middling temperatures and damp air best.

mlarner

20-02-2006, 09:39 PM

I've just refilled the tank for the first time in the new TDI ~ 55.3mpg, compared with an average of 41.7 over a total of 37000m in our previous FSI. We'll have to see if we get any increase after a few more miles and the engine "frees up a bit". What odds on 60mpg on a 16m daily commute?

sarge

20-02-2006, 09:55 PM

We get around 40mpg around town (tank to tank - the DIS is overly optimistic) with the air con on, rising to early fifties on the blast down to Cornwall (325 miles for me) - average 80 mph. 1.4 Petrol engine (yes, Audi did make a petrol A2 - most are TDI on here!) with 52K under its wheels. Mind you the 16V 1.4 also likes a drink - of oil that is!

driveforward

21-02-2006, 12:07 AM

I have a 1.4 TDI 75 and am averaging 53-54mpg according to DIS at the moment. This is over a 60 mile round trip commute covering A-roads, towns, twisty B roads and some pretty steep hills!! Average speed is 30-35mph.

toby1

10-03-2006, 02:12 PM

I monitor my fuel consuption, tank to tank, and I definitely have 2-3 mpg more with Optimax. It also "drives" better, less of a flat spot than normal unleaded. Currently I'm seeing 43-44 mpg, as opposed to 40 with normal unleaded.
Fortunately I've found a Shell garage on my regular journeys to/from Cambridge that sells it for the same price as normal unleaded in Berks. Whether the extra pence is justified for the additional mpg, well probably not, but combined with the better "drive", I will continue to use it.

Aikon

10-03-2006, 11:30 PM

I've got between 57 and 61 mpg out of the 3 tanks I've used this week! Generally I am changing gear by 2000rpm, then driving upto the speed limit in 30, 40 and 50 limits and within 10% everywhere else, I reckon if I could lose my addiction to flooring it periodically I would easily get 65 mpg!

crb1011

11-03-2006, 02:47 PM

Hi Sarge, i too have a 1.4 petrol and i find that i can get just as much per gallon as those TDI engines its just a matter of light right foot and not booting it every where. On a long trip i can get over 50 to the gallon without any problems mind you keeping just under 60mph helps with the odd 70mph.
I may try using the Optimax fuel one day just to see if I get more to the gallon. not been brave enough to use it yet as not sure if it will affect the engine management

tdiman

12-03-2006, 10:59 PM

I too can get 60+ round town but boy is it boring; now getting about 50 and enjoying driving again, had a superb run over the cat & fiddle road last week and saw 12 mpg at one stage, frightens me to think what a petrol would have been doing at that time!!

ULP

13-03-2006, 09:49 AM

On a long trip i can get over 50 to the gallon without any problems mind you keeping just under 60mph helps with the odd 70mph.

A TDI would get 70mpg in the same circumstance, assuming the driver hadn't fallen asleep at the wheel and crashed ;)

I get 52-56mpg driving on open roads, in town, on motorway, through traffic, foot hard down, cruising etc. etc. If I drove the 1.4 Petrol I doubt I would get much more than 40mpg.

crb1011

13-03-2006, 07:56 PM

just done a longish trip over the weekend around 200 miles in total and got around 50 - 55 miles to the gallon. It was all motorway and dual carridge way driving travelling at approx 60mph. I would agree if I rove around at top speed and raced through the gears then my fuel consuption would be a lot less but I am old sod and my days of driving around at speed are well gone not that drive every where at 40mph

hollyrescue

13-03-2006, 08:51 PM

I'm an old sod too, and drive fairly briskly, but not like **** off a shovel, an average of 37 is about normal, slightly better with cost a lot super petrol, but the car goes better with it, smoother, better pick up and acceleration.

Hey Guys,

I've had my TDI 90 for about a year now - and I am slightly surprised about the mileage I am getting compared to the 'official' figures. Can we start a thread of peoples A2's and the mpg's they are getting please!

04 1.4Tdi (90)
Town-48mpg
Ex-54mpg
Avg-49mpg

Guess I must have a heavy foot or something

Can anyone help? - I definitely have a problem with my TDi 75 Sport (2002 with 34k miles) which I bought recently. Gentle driving only gets it to mid 40s (i.e. way below Govt. figures). My driving style with both a Mercedes CLK and a Shogun gives me mpgs better than Govt. figures. Have had the A2 serviced at the local Audi dealer and checked twice on the diagnostics machine. I have also put a cleaning additive in the fuel (recommended by a Skoda garage) but no difference. Any suggestions would be much appreciated.

Yossarian

13-04-2006, 01:08 PM

I've monitored the consumption of my TDi 90 over 14000 miles from new (sad but true!) and get 55mpg overall.

This isn't much better than the Ibiza TDi 130 sport that it replaced, although that was used mainly on motorways (engine barely ticking over in 6th gear) and consumption increased significantly in town.

The A2's consumption doesn't vary much and it is used mainly for short commutes at the moment (including far too many speed bumps). When I do get the chance to give it a good run I find myself using the performance (it is a deceptively quick car) and haven't managed to keep it at 60mph for long enough to improve the economy!

mlarner

14-04-2006, 12:20 AM

My TDi 90 is currently on 5500m and has averaged 55.1mpg. This compares with 41.7mpg for the previous 1.6 FSi over 40000m.

Poor_John

14-04-2006, 09:02 PM

I have recently been doing a lot of short journeys in heavy town traffic and I'm getting the worst ever MPG in my 4+ years of ownership - 30something. If I can only get out of town!

Robin Benie

14-04-2006, 11:57 PM

My '05 TDi SE 75 averages around 65 - 66 mpg. On a long run it goes up to 72ish and trogging around town takes it down to 62.

BUT - I notice that going much over 70mph causes a huge increase in consumption so I have my DIS set to warn at 70. Although I keep to the 70 limit I still keep up with most traffic and have I fun on the back roads too. Using the DIS to check current consumption does alter the way you drive and you end up trying to squeeze the last drop (while still driving sensibly). I do about 25000 miles pa after work hours so I'm not exactly just pootling about.

16-04-2006, 10:36 PM

Must admit i get nowhere near audi's acclaimed figures. My commute to work of 7 miles gives me around 48mpg (car doesn't get fully warm on cold mornings) and on the motorway where i cruise at around 3000 revs (which to the 75 tdi crowd indicates my speed :D ) ) i acheive around 53mpg. I don't believe i'm heavy footed but accelerate up to around 2k in most gears-maybe i do have a problem???

Hello.

I have updated the user profile fields with the ability to store your average fuel consumption and typical fuel use. Please take the time to update this information here:

http://www.a2oc.net/forum/profile.php?do=editprofile

This page can also be reached by clicking on the User CP button in the navigation bar, and then selecting Edit Profile in the control panel.

I will put together a page that summarises this information.

Since my last posting on this subject a few weeks ago the weather has got a little warmer and I've done one or two longer runs and also varied the fuel that I've used....either the standard BP diesel or the premium version. One of the trips was a return journey to Oxford (270 miles) on a mix of A and B roads, plus some dual carriageway and motorway driving. Half the journey was with 3 adults plus luggage in the car. The average fuel consumption has now reached 71 mpg.

I don't notice any difference with the type of diesel. I haven't consciously varied my driving style...smooth, changing up at ca. 2300-2500 rpm, down at 1300 to 1500 rpm..depending on road conditions, cruising at legal limits, and the occasional foot to the floor moment.

The engine (1.4 Tdi 75) has now covered 12,000 miles and I've noticed a marked improvement in smoothness and general tractability recently. I've put this down to the engine starting to loosen up. This probably accounts for the improved economy too.

Oil consumption has been low (less than 0.5L).

It's hard to understand why there is such variability in reported economy. I think big factors are: (i) length of journey. Anything less than 10 miles and the engine doesn't warm up: (ii) tyre size. There's an marked increase in rolling resistance with the larger tyres fitted to sport and some other versions. Mine has 175x65 tyres. Tyre size also affects the drag coefficient.(iii) Driving using a partially open throttle. Diesel economy drops off markedly at anything like full throttle. Long periods of driving at high speed will hit the economy (iv) weight.

These factors are all reflecteds in the design philosphy of the A2 1.2 Tdi 3L. Audi had to reduce tyre size, reduce weight, improve drag coefficient etc. to reach the famed 3L per 100km efficiency.

The car is a joy to drive, now I'm thinking about importing a 1.2 Tdi 3L. Any advice from anyone as to where I might lay my hands on one?

Just completed a 750 mile round trip to Scotland in my TDi 90. I wasn't aiming for maximum economy but I tried to keep the speed below 70 mph (mostly!) on motorways. This was mixed with steady 50mph drives on quiet Scottish roads as well as low gear driving on some steep and narrow tracks. Overall average was 63 mpg which is my best yet.

My ECON button doesn't make that much difference - unless it's very cold and I'm turning off the Auxiliary Heater!

It's on cars with Climate Control or Air Conditioning. It simply stops the AC compressor from cooling - saving a surprising amount of fuel sometimes.

Hi all,just following theads on fuel consumption, filled up today(brim to brim)58.2mpg on Esso diesel, about my average. I find that Esso and Shell don't foam up as much as the supermarket fuels so making it easier to brim, Malcolm.

589.6 miles on a tank, absolutely brimmed at 39.75 litres when I filled it so still another 3 litres/45 miles in the tank, DIS showed 65.4mpg (and 0 miles to go 5 miles previously!)
The figures work out at 67.43mpg unless my maths is wrong. Can't say I'm displeased with that!!

Excellent! That would certainly please me.

We all know that manufacturers' fuel consumption figs are made under special controlled conditions, on a test bed and not like real driving.

In yesterday's Independent (29/8/06) in the article "Fuel for thought"
http://motoring.independent.co.uk/fe...cle1222329.ece
it quotes What Car? who say official figures should discounted by 8% to get a realistic figure.

So, taking the A2 75 TDi SE official consumption and adjusting by -8%:

MPG Urban (MPG): 49.6 -> 45.6
MPG Extra Urban (MPG): 78.5 -> 72.2
MPG Combined (MPG): 64.2 -> 59.1

Personally I still think these are a bit high. Still, I'm pleased with my 62 mpg over 11K miles, with a strong bias towards Extra Urban driving.

Just looking at the Tdi's it seems that the 75 fares much better on the mpg stakes than the 90 :) Just my luck!

The 75 seems to be around the 55-60 whereas the 90 is around 45-55.

This is not scientific in any way - just an observation!

Oh - I had a full geometry setup (tracking) recently on the A2 I'll see if that helps any!

Our TDI75 seems to be getting 55-57mpg at the moment, whereas it was seeing about 52mpg typically. The reason? Well, maybe because I've not been driving it to work very much - 7 miles each way. The car is now doing longer trips with my partner at the wheel.

i got the lowest ever figure today...dont know why filled up on at total pumps

i filled it to the brim and did 87 miles and thats for £10

must be around 38mpg

gonna try bp fuel next time

oh and i have a 2001 Tdi Se

Hey Guys,

I've had my TDI 90 for about a year now - and I am slightly surprised about the mileage I am getting compared to the 'official' figures. Can we start a thread of peoples A2's and the mpg's they are getting please!

I've been keeping a log of my fuel consumption in my TDI 90 over 17500 miles. The overall figure is 53.5 mpg which I'm pretty happy with. It's nowhere near the official figures but it never seems to drop below 50 and I have achieved 63 on a long run. It also goes surprisingly quickly and I like to accelerate!

The car has just had its first service so it will be interesting to see if there is any improvement in consumption.

ecoangel

Forget Official Figures!

They are not based on normal driving conditions - they are done on a rolling road so there is Zero Drag aerodynamically speaking and the car is not pulling the rear wheels along. Acceleration is done very slowly using a standard technique you would never use on the road.

At least it gives us a clue when comparinjg manufacturers products side by side but in the real world read an Auto Express/Autocar/Car/EVO/what ever motoring journal for a proper test result.

Hi there,
I've had my A2 (basic 75bhp with no AC) for a month now (love every bit of it) and I've tried driving it like a nun and got 69.5mpg, used it 'normally' (enjoying the torque I never had with my petrol Passat though) and got 58-62mpg and I've tried a tank driving like a loon and it dipped to 54.3mpg (shock, horror!). My driving consists of about 40% town, 40% A&B roads and the rest motorways (on which I tend to do about 65-70mph according to my Tom Tom).
I'm hoping to have a word with Skipton shortly and have cruise fitted and maybe take it up to the lakes at a steady 60mph in the hope of crossing the magic (but particularly anal) 70mpg barrier!

I love my A2!!!

Alex.

Well Idrove like a Nun for a week to see what I would get to the gallon on a weeks driveing I drive 480 miles a week mixed bag and I got 75 MPG was impressed with this but had to try though on the whole I usually get about 60-65 mpg

I get 63 mpg (4,5l/100 km) at a cruising speed of 60 mph (100km/h) for about 80% of the tank. The other 20% is getting in/out of the city. That involves usually 2-3 stops each way at one red light, one railroad crossing and one junction.

That's a very steady cruising speed! I think that would account for a lot of the good fuel consumption. I'm not sure I would like to try the average UK motorway at that sort of cruising speed - too much dicing with trucks!

Xiter

21-09-2006, 07:38 PM

I'm trying to hold it as steady as possible. Let's say the cruising speed varies between 97-103 km/h to be more realistic. Traffic is light and there are usually no overtaking. Reindeers are unfortunatley common on the road during the winter. A real nuisance to us commuters.

The figures have been calculated the classic way since I haven't got DIS.

I'm going to install cruise control so it will be interesting to see if it helps.

I have been trying different tire pressures (from 2,0 to 3,3 bars) but it doesn't seem to affect fuel consumtion enough to make a difference.

I'm using the air con as little as possible. Just for lubrication of the system and demisting the windows in the mornings.

Done 70,000m in my 1.4 TDi 75PS - average 49mpg.

The A2 isn't really designed to be a motorway car and hence its gearing is a little shorter than it should be, hence good acceleration in deisels. I think it would benefit from a chip to 100bhp and larger rolling diameter of tyres (bigger wheels / higher profile tyre). That way you keep the acceleration and drive on motorways at lower revs etc.

Incidentlly best mpg I have seen (over 22 mile journey) was 103mpg average, got to fuel station with 0 range and stuck 40L in, DIS said "Range 770miles" :D soon dropped though ;)

I've been able to break the magical 80 mpg barrier this last tankful, still including (a few) short trips. Aircon off, alone in the car (save for the short trips), 35 mi commute (of which 30 are motorway @ 60mph), coasting when possible/safe.. Even a nun would've gotten frustrated, though.
Overall average is still 69 mpg, that's over 5 years and 112.000 miles. I can only hope I can continue driving it for at least 100.000 more!
Blimey, 80 to the gallon is incredible. I'm gonna have a closer look at my tyre pressures and driving style. Does anyone have any figures based soley on using cruise at say 50, 60 & 70 mph and possibly the difference this makes against one's right foot?

I love my A2

whuy

27-09-2006, 03:42 PM

It's also partly due to the perfect weather conditions: dry, no wind, and 19°-20°C, a bit overcast (so no aircon needed), high pressure (does that make engines more efficient?)
BTW a small correction: the 69 mpg average is this year's average, overall average is 'only' 66 mpg. Still good..

I have a 1.4 petrol, on one of my frequent journeys of 133 miles all motorway, using cruise control as often as possible set at 70, I show 50 mpg on the dis, until I reach the M25 and it's road works whereupon it rapidly drops to 46. Around town all short trips e.g. 6 miles each way I get 37 if I'm lucky.
It's strange how rapidly the average mpg drops in traffic, and is never regained no matter how careful I drive.

Is this figures calculated the classic way or on the DIS?

whuy

28-09-2006, 10:34 AM

Classic.. I don't have DIS.
I make sure to fill up exactly the same way, so it's brim to brim..
FYI, it's 29.92 litres to 848.5 km (I have the small tank), which works out to 3.53 l/100km or 80.1 mpg (UK miles and gallons). Bong at 738 km (458 mi).
OK, now I know it's possible, I can go back to driving normally..
Incidently, this means that at a steady 90 kmh (somewhat less than 60 mph, between 2000-2200 rpm in fifth), you do at least 90 mpg..

Xiter

Please tell me your tire size and brand also for comparison. I'm still on my original Dunlops (175/60-15).

The terrain I'm driving in is rather hilly with few flat parts.

The standard 175/60 R15, Goodyear MCT5.
The determining features are:
- the weather (warm, but not hot enough to need aircon - even if I did switch it on at least once)
- I'm alone in the car
- steady pace, 2000-2200 rpm, 90-95kph
- avoid short trips, switch gears at 2400-2600 or so and when accelerating, make sure to do so 'convincingly', but no flooring of the accelerator.
- coasting when possible/feasible/safe
That's about it.. it's boring, but it works.

That's exactly how I drive, but I cruise at 97-103. Next tank I will be driving 90-95 for comparison. What is your terrain like? I usually engine brake as much as possible instead of using the wheel brakes. Does the A2 stop fuel supply when engine braking?

It's getting colder here now, only +2 degrees this morning.
Calix electrical engine heater (550W) plugged in for one hour before start-up.

whuy

29-09-2006, 02:22 PM

I never use the engine for braking.. or, at the very least, I never downshift for the sole purpose of braking, even if it is more economical (when you release the accelerator, you use zero fuel). I'm under the (maybe false) impression that engine braking wears the engine out faster (because forces are applied in reverse), and downshifting needlessly wears out the clutch. I'd rather have my pads replaced a bit more often.
The road is quite flat - of my 120km daily commute, about 100km is straight, flat motorway. And driving 90kph vs. 110 does make a difference. Purely from a fuel economy point of view, 80kph would be even better, but that's not feasible on motorways..
And +2 degrees, yes that means warming up will take a lot longer(disregard that - I only just now saw the reference to the engine heater), and maybe that even fully warmed up, the engine is not as economical as at 20 degrees.
Still (having looked up my data from Jan-Feb, when temperatures are around freezing), I approached 4 l/100km (70mpg) on one occasion as well, without having to resort to driving 90 kph on the motorway.

Cold climate affects the whole car. Wheel bearings, gearbox, engine, everything gets stiffer as the temp drops. On my old 1983 Ford Granada 2.0 I had to use both arms to shift at -34 degrees celsius. But I recon the terrain might be a major factor. There are few flat areas here. The extra fuel you burn going up a hill is more than you save from going down a hill.

New record achieved; 4,3 l/100km which makes about 65,7 mpg. Cruising speed reduced to 90 km/h from 100. AC off. The temperature has varied from -2 degrees celcius to +7. Tire pressure at 300 kPa (43,5 psi).

Conclusion: It didn't make that much of a difference to the 4,5 l/100 km I usually get when driving 100 km/h.

Cool thread, a few points (given that I work with car manufacturers, do loads of miles and test various bits'n'pieces).

1) Diesel fuel formula changes through the year to take into consideration ambient temperature shifts / fuel thickness. So consumption will vary relative to fuel changes / time of year.

2) Cold air is more O2 dense, hence better combustion especially if there is moisture in the air but equally colder = more friction through cold (expanded) components and thicker oil.

3) Cruise control hurts fuel consumption compared with a gentle right foot as it maintains speed up hill. Its better to gain speed downhill then loose speed uphill.

4) The old school "use the engine for braking" is pointless nowadays, it was designed for a time when brakes couldnt take a lot of heat and were not very efficient. Nowadays brakes can take it and using them rather than the engine saves engine wear (compared with brake wear which is cheaper) uses less fuel and is better for emissions.

5) I wouldnt recommend people doing this as it may be considered dangerous and you may get Mr.Plod having a word with you. But the best run I did with 103mpg average (A2 1.4 TDi 70) was mainly motorway and I free wheeled downhill and towed lorries uphill (got in their slip stream). Best fuel efficiency trip I have ever done was Donington Park to Silverstone (65 miles) doing 49mpg in an Alfa 147 2.0 petrol at average motorway speed of 80mph - there happened to be a large van doing the same trip (quickly) that wouldnt get out of my way ;) - never did get chance to thank him.

6) Modern climate control systems are amazingly fuel efficient compared with their older relations. I remember a Lancia Delta integrale where you could actually see the fuel gauge move when driving with aircon on! A2 is effected but the climate control but only by a few % in my opinion.

7) My A2 has the fuel heater in it and I think that impacts consumption during cold weather more than anything. Although its useful for heating up "thick supermarket fuel that you buy off the shelves" ;)

I have only had my 2001 1.4 TDI for a week now, but have been trying to get the best MPGs I can out of it.

I do a 70 mile roundtrip everyday on mainly motorways, and it is the Motorway where i have concentrated my efforts to get the best MPG I can.

Unfortunately the M2 seems to be made up of a number of hills, so one moment I am getting 35-45 MPG when climbing a hill and then 200MPG or ---MPG when comming down hill again. However on the flat if I tuck myself behind a large lorry at about 57MPH I get about 85-90MPG

I also use Biodiesel when I can, and unfortunately Biodiesel does know the MPG down by about 5, but then thats not the point I guess.
