Took my GLK250 Bluetec to East Hampton this past weekend and recorded 41.3 MPG going and 38.8 MPG on the return. This truck is truly amazing and I couldn't be happier. I highly recommend it to anyone looking to achieve great mileage.

Is that calculated from the instrument panel or actual pump/mileage? There IS a difference! Usually a bit less than the onboard calc's give you. I've found as much as 2 mpg difference between the two. Out of curiousity, what was average speed? I don't do that well but here in the west the open highways let you cruise near 90mph and that eats up my mileage. I'm nearer 35-36mpg.

It was the MPG on the instrument panel. I used cruise control at 58 MPH. Even if this is off by 2 MPG, it is still amazing for a 4300 pound vehicle.

It could be accurate and, yes, that is darned good! If I drove sensibly I'd expect something like that. Great cars!!

Just got back from an NY-NC round trip run with the 250. My Best MPG was on the return trip back to NY. 623 miles, avg 65 mph for 9:33 hrs getting 37.8 mpg.

Overall my 3 day total was 1309 miles, avg 59 mph for 22:22hrs getting 36.3 mpg.

Love the truck, hummed along with no issues at all the entire trip, and I really did not have any comfort issues. Which is probably why i now have 20k miles on it in 8 months.

It's definitely possible. Our last (in-city) tank was 790 km on 56 litres, which equals 33.5 MPG - and our highway mileage is usually much better.
