Please note the 67.3 mpg combined you show and Kia show in the information for this model I believe is not attainable in normal driving if there is such a thing.

I did a test as recommended by the garage who sold me my car a main dealer to simulate a combined drive of length 60 miles and the garage repeated the test in my car.

The figure achieved was 20 miles lower than the published figures.

Now as I made a decision to purchase based on the advertised figures and no doubt others have also done the same am I unlucky or is my experience relatively typical and published mpg figures have to be downrated by at least 25% to get nearer to a typical figure attainable.
