Engine size vs Fuel

[hbhudia]

I am thinking of upgrading my car for maybe a c230k or 240 sport. Now thats quite a big jump from the current c180.

What would the fuel consumption be like?

Currently I get approx 320-340 miles from the full tank in urban driving and maybe a little more if motorway.

Thanks

About the same for the C230K then (real life figures, mixed driving). I should imagine the C240 to be more thirsty.

On paper, the C230K is the most fuel efficient petrol w202.

Prior to my last service I was getting about 380 miles out of a tank, which is about 29mpg. Now with new oil, oil filter, sparkplugs and a few other bits and pieces I'm expecting the economy to improve

...I should imagine the C240 to be more thirsty...

There's no imagining about it The V6's will be more thirsty than the C230K. Depending on how I am driving I get between 200 to 250 miles on a tank of pure town driving. That'll go up by about 100 miles or so for motorway cruising. I have an extremely heavy foot around town though.

Steve that's about 15-18mpg!

I seem to get pretty much the same economy no matter how I drive.

Nowadays I get similiar economy whether it is city or motorway. When I first got the car i was getting about 380 in city and about 450 on motorway!

I get 19mpg overall

I get 19mpg overall

about the same as a CL55 AMG then according to this thread!

...my C230K returns between 25 - 29mpg mainly commute town + motorway + some jams. Long runs at 70mph return 32 - 35mpg. I suspect that the V6 will use a little more than the C230K.

C280 V6 fuel consumption

I generally average 28 mpg on mixed driving with 33 mpg motorway average. Best ever was 35 mpg, worst was 26 mpg. That doesn't seem too bad to me.

Maybe I have something wrong with my car then the best I can get on a long motorway run is just under 400 miles but my daily commute which is 100% stop/start town driving doesn't yield much more than about 220 miles a tank. I dunno if it's my imagination or not but I'm sure it wasn't as bad as that when I was commuting in my previous job.

Ok I just got 390 miles out of 63 litres, which is about 28mpg. I have been giving the car some stick too, so for this next tankful (which should last 4 days or so) I will drive sensibly and see if there is any improvement

Lot more than what i currently get!!

So whats the most fuel efficient W202? So far it appears to be C230k, what about the C200?

 

[Alex Argent]

I average around 30 mpg (BTW - it's auto). That comprises worse approx 24 mpg around town and best 33 mpg motorway.

 

[pluggers]

On a tank full I get about 300miles commuting,If ive worked it out correctly its about 23mpg.On a good run 400miles to a tank.

 

[Anders]

Just filled it up this evening, having covered 306 km with 56 litres (5,5 km/l)... This comprised mostly town driving, with about 100 km of motorway...

On a pure motorway run with speeds between 160 - 220 km/h, I would get about 420 km out of 55 litres (7,6 km/l).

 

[Will]

I think I get around 250 miles from a full tank.

Mainly city driving - not much opertunity for a decent 'run' at rush hour!

I am sure on a run that this increases significantly.

No way of checking (I don't keep records!) but I could of sworn that my previous W202 (C200 Esprit, manual) was more fuel efficient?

Perhaps it's more to do with a heavy right foot!

Cheers,

Will

I think that's my main problem too Will

You 240 guys must have really heavy feet!

The worst tank I have ever had over the last 8K miles was 25mpg totally around town, the best 38mpg on a long run at 70mph!!

My average over this mileage has been exactly 30mpg on a mixture of urban and motorway driving with the occasional kickdown for fun! I normally fill up at around 360 miles to a tank, just as the light comes on.

This is a 98 c240 auto btw. (w)aft on the gearbox is about 3mpg better than (s)narl, but it's a bit sluggish to be practical for me to use most of the time! I reckon a 280 would be the best, a little more grunt for virtually no economy penalty and all the smoothness. Mild complaint is that mine likes a litre of Mobil One halfway between services, which is not cheap at £11 from Halfords!!

 

[altreed]

With town driving and short journeys I get about 270 miles to the Light coming on, nearer 400 on a motorway run.

Go on, get a c36, you know you want to,
