Those With the S450, What Are Your Miles Per Gallon
I drive a lot of freeway but averaging 28 mpg usually at 75-80 mph.
If some mixed city driving more like 21-22 mpg.
Recent trip from SF to PS did one tank of gas. 500 miles.
Not to bad for a big heavy car.
PS: No noise intrusion.

I keep my freeway speeds between 70 and 75 mph. This is the most quiet car I have ever owned!
As an aside, do you guys know when the 2019 S450 will be available? If you read my post about "What Do I Do Now", then you know that the 2018 is not in the cards for me. I cannot find a 2018 which has the exact options and specs I want. Hopefully the 2019 also has some refinements on Distronic, etc.

I don't have a S450 but I get decent highway mileage when I drive it normally. Lately, I've decided to drive the car more in the sport mode and throw caution and cares to the wind and not worry about mileage. I make decent money so I figured - why do I care so much about MPG? It's kind of freeing not worrying about it.
I also decided recently after owning this and 2 other S63's in the past, to only use the super expensive 93 octane instead of cheaping out on 89 or g*d for bid, 87 in a pinch.
I hope it makes a difference to my baby and I hope she appreciates the effort on my part of sticking a crowbar in my wallet to pay for the good stuff.
The difference between the S450 and the S560 is anout 1 mpg in the city and 3 pn the highway but you’ll pay an extra $9-$10k gor tjose two extra cylinders.
It isn’t worth it to me, if ZI wanted a go fast mobile I would have bought an SL instead of an S, it’s a lucury sedan not a go-fast coupe.
