MPG numbers have suffered the same fate as GCSE grades.
Correct, every new model or update has better "official" figures than its predecessor whereas in the real world they achieve about the same mpg.
I take absolutely no notice of the figures when buying simply because every car in the same market area has exactly the same figure. A few years ago the "magic figure for a diesel was 62.9 mpg which translated to 119 CO's which is £30 a year tax. Now it 75 ish mpg which translates as 99 CO's and £0 tax. The cars use the same basic engines, have about the same power but probably weigh more thus how can the mpg improve.
The figures are only useful for calculating annual road tax £££'s and the company car tax bracket, forget the mpg.
