G63 AMG low MPG
If the 8.3 MPG is taken from the instrument cluster indicator then it's cumulative.
It takes into account starting, idling, low speed driving etc.
Take it out on a long highway drive and you should see the MPG move upward.
My G55K stays around 10-12 MPG in city driving but can get up to 17+ on highway.
Window sticker is average, usually a bit bloated.
You don't buy a G63 if you're concerned about fuel economy.

Over the weekend I am up to 100 miles with the same poor mpg you are experiencing but that is to be expected particularly until the engine is reasonably "broken in." And based on all of my former "G's" you can't expect much better. As someone else posted 8mpg around town at best and perhaps 14-15 on a long highway trip is about it.
Nice to know someone with an identical G63 so keep in touch.
So far really like the car, had the ESP light go off once when using Distronic but went off after a restart. So far have 600miles and averaging just around 10mpg combined.
