The cynic in me wonders if they're just very highly optimised to work with the standard economy test... certainly there are plenty of cars around with very good headline figures but which are much less economical in the real world. OK perhaps if you sit at 70mph, never accelerate or decelerate, for hundreds of miles at a time, but no matter how careful you are that's rarely possible. It still takes about the same energy to move a car at 70 as it always has, but releasing that energy (i.e. the volumetric efficiency of the engine) has certainly improved.
