MPG for W204 Petrol ?

[pareq]

Hello Everyone,

I have recently bought Merc C200K Sport W204 (2007). I was wondering what kind of MPG should I expect from this car. So far, I'm getting average of 23 MPG plus minus 4 MPG around town and about 35 MPG on motorway. I'm a soft driver that always gentle with the accelerator paddle. Never kick the paddle for quick accelerations. From datasheet, the car is specified with 26 MPG (urban) and 46 MPG (extra urban). But for myself, I'm struggling even to reach 37 MPG on motorway . Quite dissapointed with that. I am interested to know what other C Class owners get for their MPG ?? Your respond is much appreciated...

35mpg is good on motorway for you car, I suspect it wont have the blue-efficiency engine and hence its CO2 will be around 180-200. therefore 35mpg in my opinon is not bad at all. I just drove 1000 miles to paris and back - average mpg 24.2 (E55)

Sounds normal. extra urban is 56mph on a flat road with one passenger x amount of weight and so much in the fuel tank in perfect conditions.

My non BE W204 CDI200 doesn't reach the specified figures either, about 40mpg on average. Mercedes quoted figures would seem to be a work of fiction, yours would seem par for the course. I had my brother in law's E320cdi for a couple of days, that managed 35mpg seems taking a hit of 5mpg would be a good trade for a larger 6 cylinder. Might think about a C350cdi next time.

My W203 with 3 litres of petrol power easily manages about 35 on the motorway

l. extra urban is 56mph on a flat road with one passenger x amount of weight and so much in the fuel tank in perfect conditions.

It's not even that, it is accelerating to 70mph and then settling down to 40mph for 7 miles giving an average of 39mph overall, this is with a car in perfect conditions, with engine up to temperate and base model, ie no climate, no radio, no electric seats, etc. etc. etc.

I bet if you sit at 39mph on an empty road for 7 miles everyone will see the the extra urban figure, it's just that it is not achievable in the real world as we have things like roundabouts, junctions and traffic.

I don't think my auto even gets into 5th gear at 40mph! which I presume would be the most economical gear.

my brother can easily hit 40MPG with his Lexus IS250 V6 (2005) on motorway, slightly below the the quoted rate from manufacturer at 42 MPG (extra urban). However, my C200K never exceed 35 MPG on motorway, quite a huge gap from the one quoted by Merc with 46 MPG (extra urban)

 

[gIzzE]

Have you tried driving at an average of 39mph over 7 miles on a clear road with the car up to temperature??

That is extra urban, normal driving is combined, and that includes motorway driving etc.

Also, your C200k is a 1.8 engine, and it has gearing to match, motorway speeds are not its strong point, I would think a V6 would probably be more efficient sat at 75mph.

Mercedes don't quote that you will get 46mpg sat on the motorway, 46mpg is what the official test says you will get doing the above.

You need to get your head round that, if you're concerned about MPG at motorway speeds then you need to take the cars out for proper test drives. Also all urban driving is different, I get more in London than I do Norwich, but then in Norwich the roads are shorter hence more stop/start driving.

Have you seen this weeks Autocar magazine.

tests are taken on the car with the second widest wheel option with tyres of the manufacturs original equipment list, if these so happen to be low rolling resistance items...

39mph for 7 miles, easily get it. On a dual carriway run at 60mph you will get that

Totally ignore extra urban figures.
Use urban for hmmm urban driving and combined for hmm day to day combined driving. Anything else is not worth reading and is only used to "combine" it with urban to give the combined figure.

35 mpg is a very good figure for motor way driving . My 211 with the same engine only manages 30 mpg on motorways .

Happy to hear that 35/36 MPG is considerably good on motorway :bannana: Initially, I just quite surprise with direct comparison to the Lexus IS250 (2005) which just slightly lower (2 MPG) to the qouted figure from manufacturer, whereas mine W204 (2007) is nearly 11 MPG different for extra urban drive. I expect Lexus IS250 with V6 engine 2500CC will consume more fuel than mine with 1800CC. From experience and direct comparison/observation, Lexus IS250 (2005) in all cases (urban and extra urban) has better MPG over Merc C200K W204 (2007)..

My brother has a BMW 325 , he manages to average 27 mpg with mixed driving , and my 211 averages 27 mpg also with mixed driving . His best figure was 35 mpg , whereas mine has only been 32 mpg .
I think MB engines are not very economical

Driver is the big variable though.

Below are the same journey, at different times, engine from cold, a regular journey of mine, this time in a C220Cdi (5 speed blue efficiency) - normally in my C320cdi I get about 38-42mpg.

The higher figure is being deliberately gentle with the throttle, and is in the early hours of the morning, no traffic, no aircon.

Official fuel consumption statistics are truly rubbish....see Honest John for further info.

The EU tests are conducted at set speeds on a rolling road and don't refect real life driving and they are widly misleading, surprise surprise in favour of the manufacturers.

A case in point being the new Fiat Twinair which qualifies for free road tax as it produces 99g CO2 and a claimed average fuel consumption of @ 58mpg.....there have been loads of complaints from owners getting no where near these manufacturer claims and most seem to be averaging a very poor 35mpg....well off the official stats.
