29mgp from my 5.5!

[Psilonaught]

Managed this on a trip to Portsmouth yesterday. Really impressed with how frugal the e63 can be if needed. It actually went up to 29.4. my old jeep crd never managed more than 22mpg...

Very hard driving at 70 though ;-)

I've had an average of 28mpg our of my 5.5 litre S500L over the last 8,000 miles.

Full range of driving: town, country, motorway. These engines are incredible.

I must really spank mine normally then, my long term average is 19 mpg I think...

Is the sl500 the same AMG 5.5 bi turbo, by the way, I thought the would be the sl63? M157 engine?

 

[Steve84N]

NA with 4 cylinder shutdown I believe and less power...

About the same !

Hey chaps, let's not get confused here. The S500L is just a bog standard 380 bhp V8 - not only NOT an AMG or the later bi-turbo E63 V8.

Was just meaning to say that the earlier cooking bitter V8 carrying 2 1/4 tonnes (sic) gets an average 28mpg.

Completely different driving style, no foot to the floor stuff at all.....

Your 29 mpg is great - in a decade it's almost half the fuel consumption of the E55 I had a decade before.

I regularly get 28-30 on a Mway/B road run. Took the CLS63 up to Scotland in August and after 435 miles, doing an average speed of 59mph, sitting at 75/80 most of the way I got 31.6, which is pretty decent IMO for 5.5l bi-turbo battle bus[emoji12][emoji592][emoji95][emoji95]

That's impressive for that engine, and at a reasonable real world, average motorway speed not some false 56.5mph.

My Av since ownership is lower, but I do 'enjoy' it and the noise quite often...

 

[NEMESIS CLS]

Yes i agree, but of course we don’t buy these cars because of their efficiency[emoji23]
The noise is simply staggering when booted. My R35 GTR sounded cool, but an AMG V8 is just the best[emoji592][emoji95][emoji95][emoji95][emoji95][emoji95]

In September in the CL did nearly 3000 miles in France,Italy and Switzerland Averaged 25mpg.

 

[merc85]

That’s dam good going c43!

I did a recent trip up north and my CL500 4.7 TT was showing 36.5mpg.

I nearly fell off the seat as I don't normally have mpg showing.

Funny isn't it? We buy expensive high performance cars and worry about consumption. I have to admit I do observe mine but, it does not affect how I drive. On long trips I easily (i.e. not trying) get over 30mpg because it is motorways and in C or CV mode and does a lot of 'coasting' once the batteries are fully charged. Around where I live....well I'll keep that to myself

 

[moodi]

That is impressive, although smiles per gallon over MPG any day for me. Good to know these do both

 

[MrRight]

that's super impressive. I reached 29.5mpg once on a mixed drive with motorway and traffic but unfortunately my right foot got really tired at the end and it dropped to 28. that's with only 4 litres rather than 5.5 liters. so it's an amazing achievement to top 29mpg.

I'm afraid I don't know what my fuel consumption would be if sticking to all speed limits.

 

[Psilonaught]

I just wanted to point out the I use super unleaded, which has a bearing on efficiency. Using regular fuel the mpg would be a lot lower.
