My last 400 odd miles have all been city driving and that tank avaeraged 44.8mpg.
To get it over 60mpg is a real effort, and considering their marketing puts the combined figure at 65mpg I do have to wonder how they get away with it.
I agree it could do with a 6th gear, the car cruises really nicely at 90mph and it would be nice if the revs were 1800rpm or there abouts.
I don't think the bigger wheels make any difference though, I have changed 16" alloys on our 320d touring and on the 2.5tdi avant over to 18" ones and it didn't effect it at all, the circumferance shouldn't change.
I have noticed the economy has started to creep up - however that may just be because I am getting used to the car! I used to own an Impreza so my driving was slightly at odds to the diesel to begin with!
I have just joined this Audi-sport site and it seems over the past 3-4 years there are many A2 owners sharing ideas and stories among themselves. I have also joined the A2oc.net website and this is where all the U.K and Europe A2 owners meet and share all manner of ideas and advice etc.
If you cannot find the answer you are looking for on this site I thorughly recommend that you try th A2OC.net it really is brilliant.
