Planning to trade my c63 to ml63....but I heard lot of ppl saying that this beast sucks alot of gas! Is that true? What are the ave mpg from u guys?

Thx

ruleman

I gave you an answer on the other thread. The MPG is definitely not the reason we got ours... think full size pickup truck fuel consumption.

4.5 years and 60,000 miles of driving my 2009 ML63 have yielded these results consistently:

100% Highway @ 70mph: 15.5MPG
100% Highway @ 85mph: 13.5MPG
50% City / 50% Highway: 11.5MPG

You have remember that 7th gear isn't usable until about 62-65mph, and your best MPG will be at low RPMS in the bottom of 7th gear. Most highway driving requires driving at speeds varying from 50-80mph so the ML63 may switch between 6th and 7th gears, keeping you from getting good highway 15-16mpg. On trips where you can keep it between 65-70mph you will get the 15-16mpg I quoted above. Anything above 80mph and your MPG starts decreasing tremendously.

All my figures are based on Premium 93 Octane fuel.

I have averaged 13.8 in 55,000 miles of owning it. Here is a pic from a recent trip.

Perhaps it's just my car, but the onboard computer is always over-estimating my MPG. My computer also says 13-14 when my manual calculations always yield 11-12mpg. Sorry to be the bearer of bad news!

dacatz

not bad compare to my c63....i am running 16.2l/100km...which is 14.51mpg ....guess i will start looking for one....since it is bigger and my wife like to drive a higher vehicle...

schmick325

my ave is 19.1 l/100 klms but the car is 85% driven in stop/start traffic.

Still, on a motorway I can't get it any lower than 12.1 l/100 klms on cruise control doing 110 km/ph.

Recently I had an ML350 CDI loaner and it was in the 7 l/100 on the motorway. Couldn't believe it!

I think I read it on here that you must think of your cars fuel cost and entertainment

Maverick1975

Agreed I don't see the consumption much different from my C63s

Polianskyy

Mine 26-28l/100km city to 32-34l/100km in "race" mode 18-20l highway 140-160km/h I guess I have too heavy right foot

Either that or you have a fuel system leak.

ML63 AMG

Before tune I would top out at 19.2mog on the hwy of decent distance. After tune and air filters I am down to about 17.2-18.1 on hwy over long distances. Long term city avg is 11.8mpg after tune, before tune it was about 12.4

With that said .... It's worth it bc the tune and filters transformed the car, the mid range feels like a turbocharged car now instead of a normal NA 63 which has no meat until 4000rpm. With tune you get massive shove in the back right at 2500rpm. You just cannot drive faster than 78mph on hwy bc the mpg drop a full 2.0mpg going from 78 to 80mph bc you cross the 2500rpm rpm limit where ignition timing is advance ...

MetaL63

Mixed city/highway is 13s. Still new to me so launching from a dig hasn't gotten old.

09ML63

I have an 09 ML63 with 40 Kilometers (24 K miles) and an 07 Jeep SRT8, which my wife drives. My ML is marginally better than my SRT8, which is terrible. But when you buy these types of vehicles gas shouldn't be an issue! ...

MLSEXY3

I averaged 13.2 in my first month driving.
Here in Michigan a bit of street racing at 30 degrees last week, I was able to get it down to 7.2 mpg over 22 miles of playing around.
I am pretty sure I can get it to 5!

You won't save on fuel with ANY AMG car. They aren't built for that, they're meant to go fast and tickle the 9yr old in all of us.

For fuel economy, I'd recommend a diesel MB.

Bluetech is for mileage .........AMG is for fun

After 5.5 years and just about 68,000 miles of driving my 2007 ML63 AMG, I have obtained the following average fuel consumption:

100% Highway with average speed of 65mph: 19.2 MPG
100% Highway with average speed of 80mph: 16.5 MPG
50% City / 50% Highway with combined stop&go and crusing: 12.5 MPG

I use the ML63 primarily for my weekend excursions and as our long-trip/vacation vehicle. The long highway trips to and from our beach house in NC will average between 7 - 8 hours of primarily highway driving. My wife drives down to the house in her car in advance of me, so effectively, I am the "mule" with the cargo, (which I do not mind at all....).
I usually have my wife's and my luggage, along with two golf club bags and a case of wine and a case of beer, so therefore, assume an additional approx. 200 - 250 lbs of cargo weight. Also, I always have used the M-B recommended Premium 93 Octane fuel.

I do find that when I pull away from a stop light with a bit of gusto, my MPG will decrease noticeably, but my youthful enjoyment of the g-pressure feel and guttural exhaust sound of the brute power of the naturally aspirated 63 engine is sometimes just too hard to resist.

This vehicle is everything I had hoped it would be, understanding that the one real negative was that it would always be an expensive premium gas hog. My rationalization is that I just add the cost of the gasoline to the overall "cost" of the vacation or the expense of consistently putting a smile on my face when I drive my ML63.

I average 17.1 litres per 100/kms. Whatever that is converted to MPG.

MercedesDad

Currently driving my beast from Florida to Tennessee. Computer reads avg 16.2mpg (babying of course). Not bad considering it is slightly higher than my 2010 f150 4x4....and boy you cant compare on to the other!

Rippin'AV

LOL We should start a thread where everyone posts pictures of the trip computer and see who can get it the lowest

Echoing what everyone has been saying. The AMG isn't meant for gas mileage. I am actually very impressed with how good it is in the MPG department considering the size and power of the engine. My friend's S5 4.2 V8 gets worse gas mileage than my ML63 yet I've got a couple more liters and about 150 more hp. I've averaged about 15mpg and have even seen the computer read 19,8 for a few miles. Very impressive even if it is "generous" in its estimation.

[QUOTE=Rippin'AV;5687041]LOL : We should start a thread where everyone posts pictures of the trip computer and see who can get it the lowest :
Click on the pictures to enlarge it. Note: This is a 2007 ML63 AMG with over 100K miles. I drove it at a steady 60 mph, 1,800 RPM on a pretty level interstate (I-75, NE Atlanta) for better than half an hour and the reading went up to 20.8 mpg.

My 2007 ML63 AMG had today 102,452 miles on it. It has not been modified. Still is the way it came from the factory with top speed limited to 155 mph and it also is supposed to accelerate from 0-60 mph in less than 5 seconds. I would not want to change any of that.

In the last four months I drove on the interstate and on suburban roads 2,789 miles, burned 171,47 gallons of fuel, which came to an average of 16.26 mpg. Fuel consumption is my main priority and I have not seen a modification which will improve that.

I observed that driving at a steady 60 mph, after the engine is hot, I can get 20 mpg on the read-out. By noting the fuel consumption at different speeds, I came to the conclusion that fuel consumption varies mainly with the speed you are driving at and should work out to something like this:

50 mph = 22 mpg (1500 RPM in 7th gear)
60 mph = 20 mpg (1800 RPM " "
70 mph = 18 mpg (2100 RPM " "
80 mph = 16 mpg (2400 RPM " "
90 mph = 14 mpg (2700 RPM " "

ML63 AMG

Awesome, 20.8mpg has to be a record!

Unfortunately (or fortunately I should say), now that I have v5 Eurocharged tune with BLIP TCU my gas mileage has dropped off significantly. It's basically an SLS tune without any of the hardware so the sucker to drinks fuel now. My hwy numbers have dropped to high 16.Xs at higher speeds and low 17.Xs if I hyper mile it lol.

To me the tradeoff is well worth it because the tune is insane and I can take down exotics (especially 0-80mph).

Keep in mind, I have 90 lbs of rotating unsprung mass removed, so with V5 Blip on a normal ML63 I would probably be looking at 15MPG at best. The key is keeping it below 2500rpm bc that's where the tune kicks in, below that it's pretty much stock.

fritza2tt

AVB, I can corroborate your figures. They are pretty much what I get too.
I would like to take exception with some of the previous comments. For example 7th gear works just fine, at 50 mph and 15,000 RPM, 60 mph and 1,800 RPM, 70 mph and 2,100 RPM and so forth. If you are on level ground and not in 7th gear, toggle it up. It will stay there until an excessive load is sensed and then it will down shift automatically. My rule of thumb for fuel consumption is 90 mph/15 mpg, 80 mph/16 mpg, 70 mph/17 mpg, 60 mph/18 mpg and 50 mph/20 mpg. I drove mine for an hour at 60 mph from Chattanooga to Atlanta and the computer read-out climbed to 20 mpg. I would also like to say that a minimum of 91 octane fuel is required for maximum performance. Some of our high test fuels are closer to 94 octane. For normal driving in the suburbs and around town 89 octane/ mid grade fuel does just fine as long as you keep the RPM below 2,500 RPM. It would be a different story on the Autobahn cruising at 150 mph and going up an incline. There you definitely would want the best fuel you could buy. So, the answer for good fuel consumption is to stay close to the speed limits and do most of your driving below 2,000 RPM.

Tomabram

Well I average between 17 and 18 highway doing between 80-85mph. Around town is about 11-12.

fritza2tt

Tomabram, that's great! I assume this applies to your 2010 ML63. (Mine is a 2007 ML63 AMG.) Which engine do you have?
