You knew, of course, that the automatic transmission can be programmed separately for power or economy rather than the standard Adaptive Shift?
It makes a difference in fuel economy. I am not sure by how much but I think the Power setting is more fuel efficient than keeping it in Adaptive Shift. I get at least 500kms around the city and easily 600km plus on the open road. And that's with the odd fast takeoff and overtaking manoeuvres.
If you aren't aware of how to change the programming of your automatic transmission, check out the handbok on the transmission.....its not that straight forward.
