And others share the same mileage I am getting 20-23mpg. If you are getting 20mpg then that is better mileage than what you probably may be getting on a previous M5 model so in short, the turbo has increased the efficiency of the M5 compared to previous models.
I should have said thread sorry for the confusion. I was not complaining about the fuel consumption just stating what our vehicles are consuming regarding fuel.
