But just exactly who drives according to any of the Urban/Extra Urban
cycles? They assume you start with a full battery and don't care if its
flat at the end. Its pretty easy to get extra mpg if you have another
source of energy that you don't have to measure as part of the test.


Eggzactly. The test simply runs the vehicle on a rolling road to the
prescribed start stop of the test and checks the amount of petrol or
diesel used. It takes no account of the energy supplied by the batteries
via the electric motor. The tests were finalised before hybrids were
around. If it ran on batteries only during this test it would give
infinite MPG...
