2011 C220 CDi - claimed 64mpg, is this achievable?
Discussion
I'm shopping for my next company car and have spotted this shiny new C-class which claims to do 64mpg.
Now this car at first glance would be out of my price range, except that it's a 2.1-litre diesel which attracts a higher reimbursement rate for fuel (3p higher than that for my existing 1.9-litre Bravo, which averages about 52mpg) and this, combined with the 64mpg economy, takes the sting out of the higher leasing cost and makes the Merc just about affordable.
Question is, will the car really do 64mpg when driven on actual roads by humans? I generally drive pretty gently (i.e. stick to speed limits, use cruise control where possible, gentle acceleration etc), and my driving is mostly on motorways and NSL single-carriageways with light traffic, so this should work in favour of decent mpg figures, but I'm always sceptical of the numbers quoted by manufacturers. That said, I do actually get a little more from the Bravo than Fiat claim, i.e. 52mpg as opposed to the quoted 50, but this may well just be fluke!
I'm aware that this latest C hasn't been around long, but if anyone has experience of running one of these and can give me an idea of real-world economy I'd be grateful. If it can genuinely do 60mpg+ then it's a much more attractive option than the next car on the shortlist i.e. a 115bhp Focus...!

I always take manufacturers claims with a shovel full of salt.
For information - our 52 plate C220CDi coupe is a 2148 turbo diseasel - I don't know if it's the same engine or an evolution thereof in the new model. Over the past 40,000 miles it has done 39.9mpg average (it's an auto) over mixed driving conditions. Best I've ever seen was 54 mpg on a motorway run. I would expect the newer one to beat these results hands down, but 64mpg is pie in the sky.
However screw the mileage - do you want to drive something nice, or a Ford Focus?!! Strewth - get a grip man!
Sell a kidney if you have to.

Sell a kidney if you have to.I ran one for a couple of days as loaner. Granted, it was the pre-facelift version so did not have the latest economy gadgets. I tried my hardest to drive economically over a mix of urban and open roads and struggled to get anywhere near 40mpg, let alone 64. All I can suggest is you take one on an extended test drive and see for yourself.
Ta for the replies chaps.
I'm 99% certain the current engine is based on the 2.1 that they've been using for years. Incidentally, a chap at work runs an 04-plate C200CDi auto and manages over 50mpg, which is encouraging given the 7 years' worth of development time between that car and the new one.
I'm taking one for a test drive this morning, not sure how long the M-B dealer will let me drive around for but my intention is to pop it on the dual carriageway, set the cruise at 70mph and keep an eye on the mpg readout for a few miles. I do usually exceed the manufacturer's figures for my Bravo (worked out at the pump every fillup) so as long as Merc aren't telling out and out lies I should be in with a shout of hitting 60...?
Much as I'd like to throw caution to the wind and just go with the posh car, the bare figures put the Merc at £130 a month more than the current car, which to a man trying to save for a house deposit will add up over the 3 year lease. Hence I can only really justify it if the higher fuel rate and economy add up to take the edge off it... (and the Focus isn't bad, or so I keep telling myself - plenty of toys at any rate although I really don't fancy that puny engine much!)
Anyway, I'm now off to drive one, will let you know how it goes - fingers crossed 'cos I do rather like the look of the car!

Mercedes have done quite a bit to the engine in this new model to improve economy with bluefficiency gizmos and stop/start technology. The manual may save you some mpg too which is reported to be good.
I think Merecdes are quite honets with their figures. My ols CLS 320 used to do around 38mpg with a Brabus kit and my C63 currently returns 21-23mpg which are within a whisker of their quoted figures.
No disrespect, but the new C is a nice place to be and a major step up from both a Focus and a Bravo.
You know you want to......
Remember if the merc is new then it will be a bit below reported figures too.

my wife has a 60 plate 220 cdi sport estate with manual gearbox. All the driving is on b-roads, about 100 miles per day. She is averaging around 42mpg according to the dash computer .
With effort I can better this figure up to 48 mpg. Usually I get around 40 mpg when I drive it .... comparably I'll be getting 26 - 28mpg from my ML320 on the same route

If that's the only kind of driving you do (and it's on level roads, with a warm engine) then you'll be fine.In the real world, you should get low 40's on a reasonable length journey (10 miles plus) with not too much stopping and starting.
Sometimes newer cars are less economical than older ones - the EU3 cars were evry good, and most makes lost MPG when they went to EU4. Don;t forget the cars are engineered to do well in Government tests (they're not MB figures). Some cars do better than others in normal use.
Depends, it seems. I drive a new C200cdi, that did less than 30 driven fast, but not that fast.

I have a 60 plate 220 CDI Sport Estate with manual gearbox and have just passed the 24,000 miles mark. I mostly drive it on the motorway with some weeks driving around 1200 miles a week. On average on any of my journeys I never see over 42mpg, but if you plod along at 65ish (very rare) then the mpg does creep up and I have seen 47mpg

Is that on the computer - they're notoriously way our on Mercs? My 270CDi auto estate will do show 50's MPG at 75MPH on cruise, but it takes a 100+ mile run to get there, having started off at 33MPG when I leave home. I've never checked the brinm to brim consumption - it might upset me!Deva Link said:

) worked it out correctlyWell, I've had my test drive!
The only C220 CDi available with a manual 'box was a 60-plate (i.e. previous version) in Sport trim, so it lacks the latest BlueEfficiency tweaks and also had the bigger wheels.
Impressions? On the plus side, it's much quieter, smoother, and pulls better at low revs than my much-loved Bravo. Interior a very nice place to be, well put together too, should be a pleasant machine for doing long, dull motorway runs in comfort.
I did find the ride a bit firm in this car, but should I go for the C-class it'll be the SE, which has different seats, softer suspension and smaller wheels with fatter tyres - this should soften things up considerably. As for the fuel economy, doing a steady 70mph (no cruise on this particular car) and resetting the gauge it registered 55mpg after a few miles. So the newer, theoretically-more-efficient engine coupled with smaller wheels ought to be a bit more economical than this.
Encouragingly, M-B claim a mere 117g/km of CO2 for the new car in SE spec (this qualifies it for an extra "green" incentive payment, hence a 28 grand car becoming a viable option for a pleb like me) whereas the same engine and gearbox in a Sport pushes this up to 133g/km. In theory this should have a proportional effect on fuel consumption.
So far, then, it bodes well for the Merc; I'm going to have to pester the lease company to provide an up-to-date, SE-spec car for an extended test drive before pulling the metaphorical trigger, but it's looking good so far

Shouldn't make a difference as smaller wheels should have higher profile tyres to maintain the same rolling radius, otherwise the speedo will be out.I'm currently running an 11reg C220CDI estate pre-facelift and I have achieved some impressive figures from it, although they are not near 64mpg.
A recent trip from Southampton to Baker Street in central London saw an average of 46mpg, although at the end of the M4 it was on 50mpg, that was driving very sensibly.
I have found it difficult to get it over 50mpg (I have had 4 220CDI engined C-Class's for short periods of time since I passed my test a few years back) but on long runs high 40's is achievable.
Around town I would expect mid 30's from it.
I borrowed a 200CDI C-class saloon 2 years ago or so and that was not much better than the 220CDI in terms of MPG but felt very much underpowered.
Took the SL600 out the other day and it averaged 19.6 MPG, on the same trip in the C220 CDI I managed 46 MPG :O

Well I am going to go look at this tomorrow.

There are some good deals out there on pre-facelift cars.
