Just out of interest, MPG on 230K

Wifes W208 CLK 230K Convertable - Me GTR on order
What are you guys getting to a tank full on your 230 Kompressors?, our computer is showing average of 24, but that was including a run back from london (110 miles) and the rest around town.
 
Sounds about right to me...similar to the 230K Class that I used to run....never was very economical.
 
Mileage for this tank will be about 280, is that right for £60 of fuel?
 
The average from my 1998 w202 c230 kompressor is 29.6mpg, that's 420 miles from a tank.

This is worked out from 166 receipts :)
 
That's motorway miles Nick, has to be.

Varies vastly on how it's driven and where, but typically anything around 280-300 miles for mixed driving sounds right from what I recall.
 
Interesting thread in a way as it shows that even when running a bigger engine, fuel consumption does not always suffer.....I'm running a 430 CLK for a couple of weeks and a journey upto London and back today, which invloved a bit of crawling through London traffic resulted in a round trip fuel consumption of 25.4mpg....80 mile round trip.
 
I think more gutsy engines are fine on the move, the real crunch is where they are all at their worst, short journeys and stop start traffic and the biggers engines make the worst of a bad sitaution!

The C230K is quite efficient for the moderate performance it offers I think.

Let me clarify then :)

I do a lot of motorway miles, and I tend to drive quite smoothly these days.

The worst mpg on my list is 22.2, the best is 36.4. 36.4mpg would be a range of about 500 miles btw :)

I've just been to scotland (just over the border really) and was a little disappointed to only get 33mpg, I drove like a saint! :(
 
This is the point Vlad makes I think. My V6 bi-turbo will manage 30mpg on a decent motorway run. It will also dive all the way down to 13mpg on persistent town use. While the C230K isn't much better on the longer run it seems, you'll never get it that low around town, which for the 194-197BHP motor makes it a good all rounder.
 
It's simple really, for a given speed you require a given amount of power whatever the motive power source, whereas when you slow down engine friction becomes an issue and the more cylinders the more friction so greater loss.
Also more cubic capacity gives a greater thermal loss due to the surface area, especially if there are more cylinders as the ratio of area against volume increases.

That's what I was thinking :o
 
I have to be honest, my C230K was never really very good fuel wise, especially for long journeys.

I accept that it could have been worse 'around town' or in traffic, but most dissapointing for a longer run.

I expect the 208 cabriolet is a little heavier than the W202, so I wonder how much difference you'd see between a 3.2 V6 (320) compared to the 230K on a run, especially noting Vlad's comment re the 430.

I realised that, just wanted to quantify why.

I think your bi-turbo jobbie will suffer even more because with the turbos not spooled up the engine will be well outside it's efficient running range so economy will suffer even more.

interestingly properly tuned engines with good gas flowing can be surprisingly economical when operated in their peak efficiency ranges. To produce more power they need to be more efficient.

Try to keep the revs within the parametes of peak torque +1000rpm and -500rpm..
.............or drive the Golf TDi instead...:D

oh, and just so you know...at 13mpg you are outputting approximately 508g/km of Co2..:D

My C230K gets around 35mpg on long runs at 75mph. In London traffic it is less than 20mpg. Winter running consumed more fuel as does the aircon in summer. My best run was coming down the St Bernard Pass into Italy 42mpg but I never really touched the accelerator or brake just engine braking.

our c230k estate does sround 30mpg on a longish run, getting around 300miles to the tank (small tank is a bit annoying) best i have seen is around 35mpg on a run from wassennar down to Roermond at 120miles we stuck to 70-80mph but we were fully loaded with roof box, we also find it quite good around town, the torquey motor allowing the box to get into 5th at 30mph. i'd imagine if you drive very hard you will see figures dropping to the teens, but to be honest you really don't need to thrash this motor to see a lot of cars dissappearing in the distance behind you, just let it haul you along on the torque, not forgetting the C230k is a 145mph car, with reasonable 0-60 and excellent midrange performance, and if i compare with the 406 pug we had, i think it is quite economical, show me a car that has the same performance with the same fuel economy!

I can confirm what you said, also in 2002 I drove on the autobahn in Germany in my previous w202 and it did an indicated 145mph, photo taken by passenger at 140mph. It didn't feel like it had much more left in it though... also fuel consumption wasn't 35mpg at that speed.
 
I'm running a 430 CLK for a couple of weeks and a journey upto London and back today, which invloved a bit of crawling through London traffic resulted in a round trip fuel consumption of 25.4mpg....80 mile round trip.

About the same as ours , 24-26 usually .....

How do you find the car Vlad ? Do you like it ?
 
I'll usually get around 25/26 mpg average, however when ragging it/doing short journeys it is not unusual to see it drop below 20mpg.

Like everyone else I'm really impressed by this though, it's a very comfortable car and there's also some grunt there when you need it. A good balance for the mpg i think. I had a very economical diesel pug and once tuned (though much less powerful than the merc.) it was not seeing much better than 30mpg.... and it was slightly less luxurious :crazy:

For the car i'd say you're about right with your consumption. As for how far it'll go on a full tank........ i've had it two years and have never filled it right up! Might give it a go this pay-day and report back though :D

I like it and boy can it shift when it clicks down a couple of gears....on the flip side its also very good at just wafting along on a tide of torque.

Fuel consumption wise, there's not much in it between a 430 and a 320 judging from the 320's I've driven over the years.

Have to say that I still have a very big soft spot for the 320 as the great all rounder.
