A2 Fuel consumption
- Thread starter Gexx
- Start date
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!

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

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.

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.

MPG Fluctuations
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.

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" soon dropped though

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!

80mpg!?
I love my A2
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?whuy said:

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.

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..
