Real world testing would be a good idea but anyone considering buying a car based on 'economy' really ought to spend a few minutes looking on the internet to get a good idea of the sort of figures other drivers, including professional reviewers, are getting. There are so many variables involved in driving that whatever 'real world' figures are published they'll still be just a guide and there'll be those whose individual circumstances mean they'll never achieve them in practice. One thing's for certain - nobody is ever going to match the figures obtained under controlled conditions in their daily lives but some will get much closer than others.
