28.3mpg from a C55 AMG

[trando]

Hi everyone.

Did a longish journey on the motorway yesterday morning. As you can see I got 28.3 mpg... OK, I know I had only done 85 miles and I know the average speed was pretty low but the M3/M25 at this time of the day is pretty grim. Not bad for a 5.5L V8!!!!

congrats!

Yeah, its suprising what these big cars can return...of course if they are just ticking over they wont drink much fuel. Try booting it on a fast run then return the MPG!

Yup, I've had 29 mpg from my SL500 on a long run ... and that's older and heavier than your C55!

I can just get 30 mpg from my Vito driven in a similar manner, but of course diesel fuel costs significantly more.

but of course diesel fuel costs significantly more.

Does it?

The difference is down to about 8p/litre now, isn't it?

It's currently 9p/litre where we are (101.9 vs 92.9), that's 10% more ... which I think most people would regard as a significant difference?

for a fill up, assuming 55 litres, that's about £5

My dad can get 30mpg from his SL500 but then he can get 50mpg out of his E320cdi.

That's about right if you are not heavy with the right foot although my normal average is about 23.8, but then the C55 is a car to enjoy.

Both of mine have 75 litre tanks ... so that's £6.75 extra.

Even V-Power is cheaper than diesel at the moment (by 2p per litre).

If i ever did an 85 mile journey in a car with over 300bhp and a beautiful V8 soundtrack and i managed to return that mpg, i'd know that i'm getting too sensible to own such a car!

Nice mpg though.

The R129 became a bit more fuel-efficient from '99 onwards, when the V8 changed from the 4 valve/cyl. M119 to the 3 valve/cyl. (plus twin spark) M113. That engine carried forward to the R230.

In got 27mph on mine s55 amg long run ,put foot down i get 12 mph ,

you're putting your foot on the brake if you're only doing 12 mph

without sounding like Ian Flemming

You only live once - V8, Boot it. You want mpg go CDI.

 

[trando]

So the truth is I don't do long journeys very often - I have a nice sensible Honda diesel for that! Most of the time, I get mpg figs in the low to mid teens cos round where I live there are some wonderful country roads and you're right - with a nice V8 under my right foot, why on earth would I want to potter along doing 28mpg? But it was an interesting exercise!!!

If you believe the figures the dash are telling you of course

Spoke to a customer of mine the other day who runs an M5, he said he was lucky to get 12 mpg out of it

Serves him right for buying a Beemer!

Whoa! Must have lead soled shoes....

The best I ever managed from my E55 was an indicated 26.4 mpg. Still not that bad considering it does weigh a lot more than the C55 so would think about the same ratio between the two.
