E550 = Gas Sipper?
Was reading Edmunds' comparison of E550 vs. 550i vs. Jag XF, and they noted that the E crushed both in terms of realized gas mileage. So I thought I'd look up a few other cars from Inside Line's "Full Test". Surprisingly to me, the E550 has relatively excellent real-world mileage according to Edmunds. It beats all other luxury / performance V8's that I was able to find, and even beats a couple of V6's. It even beats (or at least ties) some non-performance cars of its size, e.g., Honda Accord, Mercury Grand Marquis, and Buick Lacrosse.
Thought I'd share the data here. If I have some time later, I'll see if I can find similar data from another source. Powertrains here are RWD unless otherwise indicated.

In "C" mode, it's not too bad on gas for a V8 (starts off in 2nd gear, gets to 7th ASAP). "S" mode isn't so efficient (starts off in 1st gear, holds gears longer, etc.) but it sure is fun

I have about 1700 miles on my MY11 E550 4Matic. I am getting about 22-23 MPG on my usual commute. This compares favorably with the 22 MPG I was getting on my MY08 E350 4Matic (5 Speed). I am expecting the E550 might improve some more as the miles pile on.

You nailed it. I read somewhere (C&D or MT) that W212 has a lower coefficient of drag than a Prius.
The mileage is really impressive. It beats the socks off my last car (BMW 650i vert, 6spd) which it is also faster than. I just had a C300 loaner (also 7spd) on my regular commute for a few days and honestly the mileage wasnt that much better - maybe 1mpg. Im still thinking something mustve been wrong.

M-B V8's have always been efficient for their times, especially on the highway. The E550 is no exception, although it doesn't exactly match the E350's gas mileage, it's pretty damn close. I'd say, it isn't the power of the E550 over the E350 that bothers me (in regards to me not having it), as much as it's the very comparable gas mileage, that comes even in leu of that extra power. Just shows that the V8 is a more efficient motor all around.
Both motors are about to get a lot more efficient (V6 and V8 M-B offerings), so things are about to change again.

Yeah, it actually (W212 E-Sedan) I'd say, it isn't the power of the E550 over the E350 that bothers me (in regards to me not having it), as much as it's the very comparable gas mileage, that comes even in leu of that extra power. Just shows that the V8 is a more efficient motor all around.

2014 E550 4Matic with P1/LED/Pano
I averaged 22mpg on a recent trip to Bethany Beach, DE in "Comfort" mode on my E550 Coupe. Surprised me as I never saw more than 23mpg out of my '08 Subaru STI even with a custom 'no boost' map loaded on it for just such road trips (AWD and blocky aero at play for sure).

Well that sounds plausible. The v8 could be running more efficiently and thus saving fuel.

On my mixed highway/city driving loop of about 60 miles each day, I average about 22 MPG on my E550. Mileage improved after 10K, it has 16 K on it now.
For comparison, my 2002 E320 had dropped to about 24 MPG on this loop before trading it at 155K.
