But they can't set it up any other way, or comparisons will be less accurate.

They can't change it now because they're stuck with a badly designed test that is absolutely nothing like real driving and any changes will mean you can't compare models over time

IMO what people need is a table of factors that you apply to the official combined figure to get something more realistic for each model. I know some websites provide their own mpg figures. I would put the X3 factor at about .87 which is achievable if you drive like Miss Daisy
