Hey all,

New 2016 E400 4Matic Coupe owner here, coming from a 2012 C350 4Matic Coupe. I expected from the posted numbers (10.8/7.1 -> 11.8/8.3) that my fuel consumption would go up a *little*, but after booting around for a couple days now in varying traffic situations, it's not uncommon for me to flip to check and see it at 20.0! I don't think I've seen it lower than 17-18 yet, when on the C350 it got to 14-15 on a *really bad* day, and typically sat in the 10-12 range.

Is this normal and expected?! Is there possibly something wrong with the car? Was there maybe some major update in how they reported the numbers in-car between 2012 and 2016? Or is it just that all the extra toys really do drive it up that high?

All in all I am still a VERY happy camper ... just curious what is going on with this. Thanks!!


Edit: Oh, and I've had it in "E" mode for 90% of the driving so far. :-/

Edit2: The VIN is WDDKJ6HB5GF320135 in case the options have any bearing on what I am seeing.

My typical commute from home to the office is about 10 miles in street traffic and another 10 miles in interstate traffic, which may or may not be stop-and-go at certain points. Driving in Eco mode, and with the A/C on for at least half of that trek, my average is about 24-25 MPG. If I lived near an interstate on-ramp and was fortunate enough to drive outside of rush hour (i.e., continuously free-flowing traffic), I could easily exceed 30 MPG. This car loves cruising on the open highway, but it HATES city traffic.

Wow I'm not even on the same planet as that.

Just went to pick up some pizza, drove maybe 3 miles total there and back, hitting, I think 3 red lights the entire way, and clocked in at just over 12 MPG. Econo mode, air conditioning on, engine turning off at red lights, and doing 30-40 mph the entire trip. :-/

I'm heading out for a road trip tomorrow morning, so I'll catch up on any replies late next week.

Hyacin

Ok, you nailed it. Did some major highway driving yesterday and the consumption was lower than I could have imagined! I wish I had an exact number for the record ... I'll pay better attention on the way home and edit this post. Even the "since reset" highway/city averaged number is nice and low.

Mr. Toad

Yep, like I said, it hates city driving. It's a highway star.

Hyacin

Yep, ok, I am 100% in agreement now! It was just a couple short boots of city driving that got me all worked up, but in regular mixed driving it is single digit L/100KM which I NEVER saw on my '12 C350, and on long highway stretches I think I saw it in the mid-7s, which was even hard to achieve with my '11 2.0T A5 at 2/3rds the engine size, so I am very, VERY impressed with this car!! :-)

U guys are all lucky. In my environment, crazy bumper to bumper traffic 95% of the time or super slow at crowded paid highway, 15.9 liter per 100 KM ( 6.28 km per liter ) is okey and common.
This is my driver driving the car, meaning light footed, unlike me heavy footed....
If me, I love any opportunity to red line at least 1st gear and if traffic allows also 2nd gear. Having a lively engine and not enjoying it , is a sin.
