After driving home from work I looked down and was pleasantly surprised to see 43.2 mpg / 5.4 l/100km, I must say it put a smile on my face

I recently upgraded to the 2013 GLK 250 BlueTec from a 2010 GLK 350 4matic (Loved everything about it except the premium gas requirement and fuel economy).

Now that the BlueTec Diesel engine is broken in its nice to see this kind of fuel economy and still have the torque when you need it….All 369lb-ft of it

I have always read about the advantages of Diesel but Now that I have the Blutec I get it.

It’s a torque monster when you need it and fuel efficient when you need it.

FYI: In Canada, Diesel is normally cheaper than premium and even regular Gasoline.

What kind of numbers are you getting from your GLK BlueTec’s after break in (Average & Best Case ) ?

dude, the mpg numbers you are seeing there are US mpg...if you convert that to imp mpg (which we use in Canada) you are looking at 50 mpg plus...now that there is quite impressive.

Just checked it out- 52.31 mpg imp!!!!

So your saying the full tank will get you 830 mile ? correct me if I am wrong as I found when I search the tank size is 15g

That 5.4 l/100km and 43 mpg was just my drive home from workthat day (mostly highway and probably a best case).

On average I am getting low 7s in l/100km and mid 30s in mpg(mixed city, highway and the occasional adrenalin back road mountain drive ).

Overall it’s a BIG jump in fuel economy over my old 350 and is still fun to drive due to the torqueboost

Thats why I am curious to see what other GLK 250 Blutec ownersare getting?

Time for some metric math.
1L=.264 US Gallons
100km= 62.1 Miles

So 5.4L = 1.4256 US Gallons divided into 62.1 miles equals about 43.5 MPG

I have heard reports as high as 48 MPG highway from Europe.

surfice it to say - not bad mileage for an SUV. I'll have my USA delivery this weekend and I will post my numbers.

Again; the MB figures "außerorts" are 40.6- - 42.8 MPG.

Hi!

I have a 2011 GLK 220 CDI 4-Matic that I have been driving since March/April 2011. Mostly it is city/suburban driving but sometimes highway.

My average consumption is 8 l / 100km. On highway up to 110/120 km / h it averages about 6-7l/100km above that it will be more around 8l/100km and more. It is using a bit more than I expected but the shape of the car is probably the biggest reason for this.

The 220 CDI is the same engine but not as powerful as the 250 CDI.

I once got 49 MPG with my GLK350. But then, I was drafting a big rig

-3.5L

Thats not metric math, that's US math. The imperial gallon is not the same as the us gallon. An imperial gallon (which we use in Canada) is approx. 4.54 litres...I believe the US gallon is 3.785 litres. One litre equals .22 imp gallons.

Big difference and your math is definitely not 'metric' math as you claim. Using 'metric' math, 5.4l/100 kms works out to well over 50 mpg imp.

bigd69

Didn't say anything of the sort. Just calculated the results from a short road trip based on info provided by the OP. The original post, and it seems the fuel consumption calculator on the 250 seems to calculate US mpg along with metric l/100 kms. Seems odd, should be either both imperial or both metric.

I'm thinking there must be a way to reprogram the mileage calculator to make it this way.

EVTee

Wow! I could only wish to achieve something similar where I live. It's a little too hilly to get those awesome number. Best I got on the highway was 6.5L/100km with close to 2000km on the clock.

Fuel consumption for my GLK250 Bluetec from new. Combined city and highway. The average speed gives you an idea of the breakdown of highway/city.

madanark

Simply put, not worth the investment if highway is 33 and city is 24 mpg.

Strange - in canada the Bluetec is cheaper than the gas model but in US it is more? However, owners can tell you that the EPA estimates are very low. See posts with actual photos.

Alex Bel

In US GLK250BT ($38,590) is only 4Matic version and is $500 less than GLK350 4Matic ( $39,090)

Gt. Dane

Thanks. Makes more sense now.

NYCGLK

That's awesome. I average 16-18mpg on mine (non diesel).

3.5L

All city driving I presume?

My 2012 GLK 350 is showing 21.7 MPG combined average for the last 10,000+ miles...

Has anyone in the US purchased the 250 with the EPA mileage estimate being 33 mpg highway and driven 150 + miles and got a pic to show what the odometer/dash reads?Could you post?

I saw the discussion above of Canadian pics and read about the US vs Canadian gallon but cannot get past what MB [EPA] lists on the sticker. A couple posts would help of US mileage [sure its ok to drive in Canada if you bought the car in the US with the sticker as described]. Thank you for allowing this annoyance.

NYCGLK

Not really city, but a lot of lights, driving in/out parking garage.
I get 22 MPG only only on highways and it's usually closer to 20.
Winter months don't help either.

My wife took delivery of her GLK250 yesterday. She drives 70 miles round trip to work (on flat Texas highways) so I will have a good data point to post by Friday.

madanark

Thx Scott, Look forward to that data.

ScottTX

I don't know how to easily upload photos but the trip data as of yesterday was 243 miles 33.9mpg. This is roughly 210 highway miles and 33 city (as well as a few throttle presses by me to here the diesel and turbos purr!) The mpg after the first day was 37.3mpg (all highway)!

From what I have read this should increase a little as the engine breaks-in.

ashwats

Can you please elaborate on this. I am trying to figure out the same.

bugelrex

concerned too, but there's not upfront cost for this (other than giving up the V6). However some concerns

- if dont drive much, the adblue might have to be flushed out every x years as it degrades. extra cost
- loss of spare, inconvienent. extra cost of run-flats
- unknown extra 'hidden' maintaince costs the dealer might add for diesel engine. is there really nothing besides adblue solution fill/flush?

Essentially if MPG is the only reason to go glk250, is it worth it?
