So take a guess at the average MPG over 2 years of ownership.

Car is a C220 CDI Sport Coupe - Auto Blue Efficiency

37mpg!!! Shocking! this car promised 50mpg+

driving was 50/50 motorway and urban

 

When looking at mpg of vehicles I look at the city mpg and that is what you will get as an average for the car you buy.

The way vehicle manufacturer produce the mpg figures is to put a tiny amount of fuel in a test tank , run the engine on a rig for a few minutes and calculate that usage from a small, short test. Complete fantasy.

 

Heavy foot?

 

Not bad still I would be happy

 

That's not right, have you added adblue?
I get at least 35 from a Clio 172 and 37-38 from the bmw 2.0 petrol all urban with no miss daisy driving either.

 

I have an MY13 220 cdi blue efficiency saloon with 7 speed auto similar to yours.
I've done 5k miles since new in march and around town it's averaging 38mpg.
Once on a steady motorway run it jumps to around 55mpg.

I don't think it's too bad although as you say not what MB suggest it should be doing.

Nik.

 

I have a 2003 c220 thats done 113k miles. I always get around 50mpg from each tank. I hit 60mpg on a 4 hour trip with cruise control set at 70mph

 

How much they go for? Any major probs?

 

Well, when all is said an done, you don't buy a diesel to save money.

 

Are any of these figures calculated or are they trip computer figures?
My 330d averages 37-40mpg (calculated) and I don't hang about!

 

That can't be right. I have a 350CDI S Class which has 2 extra cylinders, 1 litre more engine, and probably a good half-ton more weight, and I average around 39mpg. Driving is 80% on A-class roads and motorways. Extremely careful driving will easily return over 47mpg on a trip.

 

Same engine. Mine was a 61 Plate

 

From the trip computer. I don't hang about either

 

Try it calculated - this car is the first one that has been even close to accurate! I do the maths every fill up and it's always within 1 mpg of the trip figure.

 

My Mercedes has a petrol 2.0 Turbo and I average 32mpg, mixed driving. I would be a little suspicious with 37mpg in yours.

 

mpg is far more a driver issue than the vehicle , it's ok saying urban or cruising down the motorway
It's how you reach the cruising speed or how quick you go lights to lights on the urban run
My 320cdi is fantastic on fuel and can return well into the 40,s with great ease , yet I was speaking to someone with a similar car and he said he struggled to get more than low 30,s and was convinced there was a problem with it so took it to a couple of garages , but no problems were found

Driving style is the key
