2016 S63 AMG
S63 10.5 MPG Avg?

I recently purchased a 2016 S63 AMG. In an effort to deflect the immediate rush to judgment, I didn't, of course, purchase the car for the gas mileage. With that said, however, I did notice the gas guage (in percentages of remaining fuel in 5% decreases) quickly start dropping down to 95% 90% 85% etc etc.. I immediately tried to find a setting that would change the % (still haven't figured that out - if available at all...). I have had the car for about 2 months now, have mainly driven in non-highway settings, and have an average fuel economy (according to the vehicle's computer) of 10.5 MPG's. Any thoughts on why the poor efficiency? I have not been driving like a mad man and as far as I know gas is not being syphoned by a neighbor...lol!

My ‘19 averaged 15+ since new, but I have a very heavy right foot.

10 sounds low.

common and economical way to fix this...I added a small chunk of 2x4 behind the gas pedal. Really helped gas mileage, killed performance, but really helped stretch a tank of gas.

Sounds exactly on the nose

That is what mine gets in the city, I drive it hard and fast and it shows over the past 1475 miles, I get 10.5 MG. It is what it is.

If you purchased your 2016 S63 was purchased at α Mercedes dealer and was CPO, I would take it back to the dealer as have it checked out, 10.5 MPG is off.
