E220 CDI, great mpg!!

[Red C220]

With ambient temps near freezing and a 12 mile run, I wouldn't expect much over 30.

However your full tank range suggests an overall average of just over 40 mpg.

My 5 speed auto 220 never did much over 40. Nothing like the 50 plus from newer 7 speeders.

We have the newer 7 speed E220 CDI and you can see from my signature below what the real world mpg is. We're not impressed so far but hope summer will improve things.

poor mpg on E220

Hi
I am a proud new owner of a E220 estate 7 gear auto 2012 model SE
I have only done 90 miles but the mpg is terrible. I have done a mixed bag of driving motorway and urban and only showing 34mpg.
I am not sure if I have set up the mpg monitor thing correctly. Is this a common mistake or is the mpg that bad.
Any suggestions please.

Have you tried putting it into sport mode first thing in morning? I noticed that my MPG seemed to improve so I guess it warms up quicker!! In Eco mode the revs are barely over tick over for ages.

My W210 E320 CDI has done an average of 33.8mpg (gennuine brim to brim) over the past 9000 miles, driven gently, usually a 33 mile commute with 20 miles motorway. Best was 46mpg on a 260 mile round trip on A roads and motorway.

Trip computer says 40mpg over the last 3000 miles, so that is a complete lie!!!

Trip computers do get a little confused, I find mine is the most accurate when I drive consistently for the the whole tank, which is rare. Usually I just drive the car these days and not worry too much as I don't do so many miles currently. However, when I get down to the last 1/4 tank I tend to drive more economically until I eventually get fuel. This bumps the average for the tank up a bit over the last 100-150 miles, squewing the calculated MPG. This discrepancy is made obvious at fill-up time, with the car reading 2-5mpg better than reality.

Conversely, if I'm consistent over the entire tank - be it pottering the entire time, or driving a little harder - the calculated MPG is usually within 1-2mpg of reality.

Remember also that these cars do adapt to your driving - though I've no idea how exactly. I.e. If I do a certain trip, having been driving the car harder for say the past couple of weeks, but drive with economy in mind on this particular trip, I might get 45mpg over that journey. If however I've been doing nothing but pottering those past two weeks, so driving economically, then do this trip also driving economically, the car has returned as high as 55mpg on the same trip. I wondered what the hell was going on at first! Note: the route in question is a good mix of town driving, 40, 50 and 60 Zones as well as some severe hills - a good, varied drive.

One thing I have noticed is that as long as the terrain is fairly flat, fairly good MPG can be achieved driving around town, as it can on A and B roads. The thing that really kills MPG for me is hills - I live in a rather hilly area so my car reports 14.7mpg when climbing the steep hill from home. Traveling back from my friends, who live in a flat area, sees the car at 40mpg+ almost right away.

Anyway, some GREAT mpg figures here! It's nice to have luxury but also be frugal. I seriously looked at getting a 220 or a 250 but sorta fell for the 350 in the end. Averaging 40mpg+ from that so far, so can't complain

Scoob.

Mercedes website states my cars mpg as:

51.4 urban
74.3 extra urban
64.2 combined

I'm getting about 42 on my 22 mile trip to work with a best of 47 on a 90 mike trip to the lakes.

I sometimes wonder if the car is changing up into higher gear to soon in Eco mode! It's doing about 1200 rpm at 50 mph in 6th in contraflow

Probably so. But all will be the same.

This is where remapping comes in and corrects the OEM maps that are set to achieve the amazing mpg figures during the EU tests, that can't generally be replicated in the real world.

Almost managed 50mpg on a trip to blackpool with the kids today . Virtually all motorway at 70 mph with a few miles at 50 mph through road works. Onboard computer read 49.6!!

It was in sport mode all the way as I find driving in E mode very dull. Anyone know if there is a way to set the car up so it stars in sport mode all the time?

These e220 cdi are good, I have a w210 e220 cdi 6 speed manual, and that does great MPG,

E320 on a round trip from Surrey to Staffs, then on to South Yorks and back down south in the last two days. Sitting at around 60mph (or 50 in roadworks) with cruise control on, I rarely dropped below 50mpg and often hit an indicated 60+.

Started off with a full tank, now showing half a tank. Not bad at all.

Economy started to increase possibly due to warmer weather and summer diesel. Used to average about 40 mpg on motorway to work ( 25 miles) including some 50 mph sections. This is now up to about 48 mpg on average with low 50's on occasion.

Cars done about 6k now so maybe some of it is due to increased mileage.

Still miles of the quotes figures......but at least it's getting nearer
