how as well, never seen close to 450. 375 miles on a tank is the best I've seen on highway with 67mph average and 21.4 mpg (I made a picture, usually its lower especially with the city involved)

 

Have seen 400 miles many times at 70+ mph (largely flat land) in the 2015 E63S.

A delta of 50 miles is not insignificant.

 

I'll have to see if I have a picture of the longest distance I've had on one tank. But, when I know I'm going a loooong way on the highway, I have it on C/Eco mode. After something like that, the car always says it can go 500+ miles in one tank, which I do not believe is possible.

 

Is the m157 programmed to shut down 4 cylinders while cruising in C/eco?

 

This is the highest mileage pic I have in my current phone:




As you can see - it was hot, so AC was running.

 

I believe the answer is no cylinder shutdown on 212. I think 213 has it.

 

Here is where the car was saying I could get 500+ miles… I don’t think that’s possible.

 

impossible

I’ve been driving my wife’s C300 Cabriolet for a couple weeks and it’s really weird not having to fill up all the time. I’m still on the same tank!

 

I’m in kms and when I fill the E63 it reports 700km range. Lol. In S+ I get 350 kms, in C I can hit 500 kms. I have a heavy foot.

 

Air was great today gave the old car a bootie call and she was just as good as I remember

 

It's boost weather! The car seems to transform (understandably) under 60F
