  1. It is possible during a simulated drive on a rolling road. The mpg figures are useless as an absolute measure, but they are useful when comparing vehicles.
  2. Yes, but rolling road tests are the only way to objectively test the mpg of one vehicle against another. Unfortunately this removes the biggest factor the affects fuel consumption - drag caused by wind resistance. Because of this it is more a test of ENGINE/TRANSMISSION efficiency rather than overall CAR mpg as different cars have different drag factors. However I do see more and more caveats appearing in manufacturers mpg data now due to complaints probably. All that said if the mpg is just used for comparisons between vehicles it is still useful as it will indicate which vehicle will likely have the best mpg based on actual road use. We know from people posting here that good mpg figures are possible and I am very happy with the dash indicated 45 mpg I have averaged in 21 months of driving my Ecoboost Fiesta.
  3. Rod, tuning has nothing to do with the effect of speed on mpg. It's a simple case of physics ie the faster you drive the greater the atmospheric drag. The effect is so dramatic that, say you double your speed the drag increases four fold, heavily reducing mpg.
  4. Remember air resistance is lower in town!
  5. Yes, but equally I could say what has love got to do with it?
  6. I have now reset my vote to show 40 - 50 mpg.
  7. Actually, long term (not resetting av mpg) and driving without particular regard to economy on a variety of roads, the indicated average mpg has now settled to read between 44 and 45. I think that is realistic and I'm still happy with it. I can't be bothered to drive like Miss Daisy.
  8. Dan222, your speedo does not indicate mpg as well lol! I too have isolated cases of mpg greater than 60, but they are transient and probably accompanied by average downhill travel. In the long term, dependending on the many factors that effect consumption I believe that an indicated 45 - 50 mpg is realistic. This was after an initial estimate of 50 - 55 mpg which I think was down to over-cautious use of the accelerator to keep the engine off-boost as much as possible. Anyway I'm still pleased as it still beats my old MX-5 by about 10 mpg which had the same top speed and acceleration (0 - 60 mph).
  9. I read your linked post, but I have to say that you should be very cautious when getting high mpg figures for certain stretches of road. I managed to get an average reading of 61 mpg after driving down a certain route a couple of days ago and had me thinking that I could have hit 65 if I had kept going! It is highly likely that these routes are averagely down hill, but that wouldn't necessarily have been apparent whilst driving. This high mpg would have been compounded if lucky enough to have a strong tail wind. Anyway my next journey saw my average mpg return to it's long term average of around 51 mpg which I think is a more realistic figure.
  10. Hi Well I've just proudly voted in the 50 - 60 MPG range - just! My Fiesta Titanium 1.0 L (125) which has covered nearly 3000 miles, mainly on rural roads and on standard grade fuel, is indicating between 50 and 53 MPG depeding on how hard I drive and whether the air con is on max chat or not. So I am getting within 80% of the book MPG which I am very pleased about. This was after resetting the avg mpg indicator from new. It is worth resetting it frequently and then you can use it to drive by to give you a good indication of your driving efficiency. If you don't reset it, it builds up old data and becomes less sensitive to changes of MPG as you drive. The instant MPG readout is as useful as a chocolate fireguard and they could have used this display for a moving average readout negating the need to manually reset the avg mpg continually. It seems some people are disappointed with the apparent shortfall of MPG, but I have to say that my pevious was an MX-5 1.8 which has virtually identical accelaration and top speed to the Fiesta and driving them both at a push the Fiesta still beats the Mazda by about 15 MPG! Although the Fiesta is not quite so quick round a roundabout, at least you don't get rear wheel drive ruining your day. All round, the Fiesta is a stunner IMO.
