Which motor between the 2 avgs better mpg with all things equal?

I think it's going to depend on wether it is tuned. I am getting...
21/24 MPG When it was stock.*
19/21 *MPG tuned

The power that it now has is well worth the trade off in MPG.

I don't think anyone buys a CLS55/63 if they're after fuel economy, but those are some pretty impressive MPG numbers you're getting. If I'm very light footed on the highway I can get 22-23 MPG, but there's no way I'd get even close to 21 in the city. My city average is in the 15-16 MPG range. Stock. We're heading out on a 750 mile trip tomorrow, so I'd love to know your secret.

yea me too, i get 12mpg city, with a heavy foot, (i just bot my car). also i thought your suppose to get better mpg when your car is tuned?

NO secret… just easy on the gas pedal.
It does get better MPGs in C. Other than that I “generally” take off from red lights slow and don’t drive aggressive. Use the cruise control when you can and coast when approaching a red light.
I wish mine did.
Trust me when I am alone and there is no traffic I drive it like it was meant to be driven! LOL With that much HP under the hood I’m like a kid in a candy store, just cannot wait to get into that throttle!
Heavy foot = 16/19
That was the worst I have ever seen it!

I'm getting 12/15 city and 20/22 on highway.

worrying about gas mileage is for poor people

I totally agree with what has been said, the decision btwn the two should not based on mpg, or should this even be a decision factor when considering this ultimate machine. I test drove both when purchasing, the driving experiences, feel, and sound of both are different in my opinion, these were therefore my decision factors.

I care less and less about the cost of a liter of fuel everytime I nail the throttle. If you are concerned about MPG please go buy a prius and leave these cars to people who will drive them in anger like they are supposed to be...

Co-sign. I doubt MPG is that vital of a factor to persuade you to buy one over the other. But WOW..I don't even get that many mpg's in my non-amg on the highway and I have taken a trip that had my gauge go from full to E before ~375 miles. Of course I have a heavy foot.lol

Unfrikingbelieveable that someone who's been here a while asked a question and got a total bull$h!t comment from a noob.

Get the #$%^& out of here.

Just a simple question. More out of curiosity because the 55 is supercharged w/ a 5 speed vs. the 63 being NA w/ 7 gears... pretty funny the reaction people get.
The reality is my CLS63 gets the best MPG of all my cars.

fn3423

I agree, it's the trany...
Gear ratios
7G Tronic: 1st 4.377 2nd 2.859 3rd 1.921 4th 1.368 5th 1.00 6th .82 7th .728

And the New CLS63:

Quote:

Design in Mercedes CLS63 AMG US Version with Exclusive: AMG SPEEDSHIFT MCT 7- Speed Sports Transmission. Beautiful design, the best performance and innovative efficiency this is what the new Mercedes-Benz CLS63 AMG is all about. The top-version-of-range four-door coupe is equipped with newly developed AMG V8 bi-turbo engine, the maximum power to 557 hp and 800 Nm of torque and the AMG SPEEDSHIFT MCT 7 – speed sports transmission. On top of that, the fuel consumption of vehicles of
28.5 mpg is a 32 percent increase over the previous model (and all numbers).

Does it matter how long I've been here? I have a CLS AMG. I have as much right to be here and comment here as anyone else. I'm not the only one who thinks its a pretty ridiculous question so bite me you phag.

self control people

You tried to act as a snob, you came off like a shallow uneducated retard.

You immediately became defensive and pointed to a car as proof of your worthyness shows your extreme lack of self confidence.

You resorted to calling people names when things got hot shows how much of a low class you are.

This forum is most comprised of people who are helpful and cordial to each other. When a low life like you came on and making stupid judgement statement on a real question, you will get called out.

Hard as it will be for you, try to act like a civilized adult. You may find that's it's just impossible, but you can tell you momma that you tried.

I drive reasonably , not racing from light to light like a 17 year old in a mustang GT but also not driving like an old lady in a corolla.
Transmission is in sport mode 98% of time. Car is totally stock.
I commute in NY metro area so a lot of stop and go traffic.
For the performance that I get, I am quite happy with this mpg.
Previous car was an e39 bmw 540i m sport auto with 282 HP v8 which averaged 18.3 mpg.

For almost 200 more HP and Car and Driver tested 0 -60time of 4.2 secs vs 5.6 for the bimmer, I will take the trade off of 2 mpg less.

I also have an audi S4 with 4.2 litre v8 340hp and it gets SL worse mpg than the CLS55 but that is the dirty secret or price one pays for ( the advantages of) all wheel drive.

I hope this is helpful to those interested.

Yup, people who resort to name calling are really low class uneducated retards

The internet is serious business bruh, gotta put these nOObies in their place right? Tell you what, I'll stop posting right after you DIAF, deal?

The 63 should get better mileage. Is the CLS55's supercharger on a clutch like the E55? I think that save some gas if you don't have a heavy foot erhm......fn3423
