Very few cars achieve their quotes mpg figure. According to the real mpg section on here a 1.1 crdt Rio will get between 60 mpg or 66mpg for the newer 2017 on model.

Is anybody to have owned the smallest diesel engine Rio on the market? I am think to buy this car, I have taken a test driver I like the car, I am aim to buy the most fuel efficiency rather the performance for my long driving to work as I am self-employment take medical tablets etc. to the hospitals in Southern of England, which I am average 120-190 miles per day. My currently car is Fiat Bravo 1.6 Mutljet Eco now is at 178,600 miles is start to leak oil from the crankcase seal it can be repair, but the bad rusty on the subframe is about time to look for another car. When the Rio say it can do 78.8mpg I was wonder if it is real figures? My Bravo was supposed to do 64.8mpg, but I am only average on computer trip 57mpg (the real mpg is round 54mpg)

To confirm Oil Rag's post, here are the links to the Honest John Section in question (generally - chose your make, then model and then see the table for each engine type):

The link is on ther main header (HOME - got to the right hand side, next to FORUM)

The the exact details for the latest two Rio models from 2011-17 and 2017 onwards respectively:

It's a handy feature, though it is more so the more people populate the data.

Note to the mods that it may be useful feedback to the site owners/staff that like with the TyreReviews website, the number of Real MPG figures for each engine size per car model needs to be given, to be able to assess the accuracy of the figures quoted, as it could just one person's data (unreliable) or 100 or 1000.

We just don't know - it doesn't necessarily correlate that popular models (by sales) will be those with the largest number of figures - it likely more depends upon the buying habits of those people who regularly frequent this website, which may skew the results somewhat.

I also believe that it would also help accuracy if each person entering the data also had a choice of 'driving syle', as a 'Captain Slow' type would like achieve a better mpg for the same car/engine as a boy racer.
