Impressed with highway mileage
Set the cruise control for the 1.5 hour ride home from the dealership at a leisurely 64mph, and mileage was 50 mpg (4.7l/100kms, since I live in Canada).
That is something else.
Around town I'm currently doing 8.5l/100 kms (27.6 mpg).
According to my research, many testers got better real-world mileage from that vehicle than the EPA estimates.
The E-class with the same engine was the fuel efficiency king a couple of years ago, so it makes sense.

This is a picture I took 1h12 into the trip, I had driven 115 kms @ 95 km/h average (59 mph) since I had driven in town from the dealership to the highway, and there were 2 constructions zones (2 miles each, where we had to slow down to 50 mph).
That's with the A/C on.

6.4L/100 = 36.75mpg (US)
7.1L/100 = 33.13mpg
By the way, I gave up keeping fill up fuel consumption records because they were almost same as those on display.
Another by the way - we drive at about 110 to 115kph in Canada. We have insurance provided OBD monitor that encourages us not to speed!
By comparison, our 98 E320 used to get about 32mpg (US) on highway trips.

The Best of Mercedes & AMG
I have checked the pump MPG against the GLK's readout and it was within a 10th or two.
One thing to think about is driving a diesel like one does a petrol will very much effect fuel economy to the negative.
I would average about 25-26 MPG when pulling a car trailer with the Caterham on it.

107123210, I do agree that this is not that great. I've had the vehicle for a little under a week now, and since coming home, I've done nothing but stop-go city driving, i.e. my morning and late PM commute, and running a few errands during the weekend. The overall average has yet to get above 7.0l/100 kms. According to the trip computer, my commutes range between 8.1l/100 kms to 10l/100 kms on the way back home, since it's uphill all the way.
I would guess that driving at around 115 km/h on the highway (which is a lot more normal than the snooze-inducing 103ish I cruised at coming backl from the dealership) would affect it somehow, since the vehicle is shaped like a brick.
The figures I quoted for highway mileage are based on getting on highway, setting cruise control to 115kph and hardly ever touch brakes or pedal for 100s of km.
Driving the GLK is not much like driving other MB diesels (we have owned a few!). Much more gas-car like and sporty. No need to floor pedal just to get her going like the old W123/126s.
More likely low MPG results are down to a lot of city stop & go driving or just plain bad driving habits. Stop & go is not the best venue for a diesel engine in the first place. Diesels do not like to be revved.
That's is why I mentioned that if you drive it like a diesel, It will be much happier and certainly last a lot longer.
If I was on the hunt for a diesel SUV (which I was until recently), my research would lead me to forums, where I'd like to have such info.
Unless that's not what he meant by that? I dunno...

Just drive an enjoy. The fuel consumption is quite good, and cost minimal compared with other costs of car ownership! (Like MB's service charges!)
That's a lot of full throttle (when I'm driving, not so much when the wife drives) and on the highway we typically do around 130 km/h.
with that said the absolute worst was still a respectable 10.9 so I'm not complaining....
