Diesel mpg question 220/250 d or bluetech UK
Would love to hear what you guys have been getting to see if they are all rubbish or just mine. I don't drive in rush hour traffic and generally use A and B roads. Driving style is efficient as I can be while keeping up with traffic.
Day to day mpg: 37 to 40
Long distance motorway: 42 to 45
Is it me or is this rubbish? I have been known to see 28 to 32 when venturing into the city.
If I drive normally without worrying about mpg a day to day average would be about 35.
Overall (from the trip comp) I have got 45.9 mpg over the last 4,000 miles. Most days consist of half a dozen short trips (2 miles, or so, round trip) taking people to/from work, so hardly getting warm - driven in semi-urban areas. At weekends we will take longer trips (50-60 miles) across country (not motorway) - I certainly don't hang around, but I'm not a boy-racer though - I do like Sport/Sport+ or manual.
The overall consumption is pretty much identical to my manual W204 C220 I had before, so given this one is Auto, I am pretty impressed, TBH. Well, maybe I had just "managed my expectations"....
I don't really try for MPG and tend to have a 50/50 mix of Sport/Comfort.
Trending Topics
Average of 44.6 MPG with a best tank of 47.5 MPG and worst 38 MPG (The urban one)
Was hoping for a number starting with 5, will see what more mileage brings.
The Best of Mercedes & AMG
Average is from actual fill-ups not from the car but the car is very accurate anyway
The one thing I have noticed is as soon as winter diesel appears at the pumps at the end of OCT the MPG drops significantly, just as it went up in April ish

Getting 60ish% of the official mpg on a 2 litre diesel is poor game. Really was expecting to breeze into the 40's day to day and 50's on a long run.
This car is the best official mpg of any car I've ever had but yet it's the worst mpg I've had from a 2l diesel. Mpg real to official % deficit wise it's the worst I've ever had by some margin.
I can get near the official figure if I drive like an OAP, if I drive normally no chance and if I drive aggressively well I may as well have a Lamborghini.

I drive in Comfort mode pretty much all the time, and I'm finding the instant fuel usage option on the small screen behind the steering wheel quite interesting, and helpful in looking at how I drive around town.
I am pleased as mine is the 250d auto but with 4matic permanent 4 wheel drive. I never did believe the published figures but on the right journey with little stop start or hills and with warm temps it can be quite frugal especially given its power. I think driving conditions in the uk really make it hard to achieve good mpg too much traffic and too many traffic controls meaning lots of stop starts.

Something I do find and don't know if it's related is to keep a light throttle to maintain a speed be it 30 mph, 40, 50mph the instantaneous mpg drops to around 15mpg is yours similar?
Also I need to travel around 8-10 miles in a morning before I can touch 30mpg. I live in the countryside no traffic and open 50-60mph roads.
I'm not surprised if it is faulty as its already had a new aux belt and bearings due to a squeak at idle, update on the fuel pump due to not smooth crawling, command updates due to phone sync issues and mpg issues since day 1.
I tend to brake early or coast up to lights etc. which is how I was taught in a day's course I went on, funnily enough by a rally driver.
He told me that there are more ways of slowing down than slamming on the brakes at the last minute, an also by not slowing own too fast, you don't have to accelerate back up to speed as much as well.
I do use sport and sport+ as well though when I want some fun
Try using the real time fuel usage guage to see how you are doing and where the mpg is at its worst and best once you've had the work done
In Australia we only have the C250 Bluetec; what is the difference between this and the C250d? I just thought it was naming conventions, being both diesel, but it sounds like they are different models?
Just for comparison on fuel economy, my W203 C220cdi, i can get down to 3.8L/100km at best, but regularly see 4.1L/100km on 40km motorway trips at tail end of peak time.
I'd imagine the efficiency wouldn't change that much unless I use the ECO mode.

What is the quoted book figures for a C250d amg line estate on 19" anyone??
I am asking mercedes to look at it on next visit. Anyone had any joy with it yet?
I had a c220 courtesy and it seemed a quite a bit better.
Trip total (in kilometers) since mid March 2015, when I picked up the car, is 7,800 km.
On board computer (since reset when I picked up the car): 10.2 Liter per 100 kilometers = 23.06 Miles Per Gallon (US)
Actual figures (fuel station receipts): Total liters: 749.56 liters => 9.61 Liter per 100 kilometers = 24.47 Miles Per Gallon (US)
I've driven around 1000 km on highway (max 120 km/h), rest is city driving (mostly 2x 6km commuting, with bumper-to-bumper traffic).
I turn off ECO Stop/Start as soon as I start to drive.
AC is on (always) 20°C (auto mode).
I drive 95% in Comfort Mode. 5% in S+ (and some aggressive driving) when possible.
18" AMG wheels with runflats (SUMMER: CONTINENTAL CONTISPORTCONTACT 5 SSR, WINTER: PIRELLI SOTTOZERO 3).
I only use premium diesel, and I go for a full tank everytime (mainly Total Excellium Diesel, and I tried a couple of times Shell V-Power which is of the same quality).
What do you think of these figures? This is the first time I actually cared and decided to pull the numbers (thanks to this thread)
