After a couple of months of driving my C63 507 I decided to check out the average mileage. Over the past 2267 miles I appear to have averaged 20.6 mpg which surprised me in a good way. The average speed was 47, so it definitely wasn't all city and definitely wasn't slow..

Time for a road trip!

 

Sounds like you should give your car back and get a prius

 

Wow, that is impressive. I have only seen 21.9 MPG in the car. That was going 62 MPH in 7th gear on a very flat, straight, concrete Interstate. How do you get 20.6 mpg Average?


For me: 7 months at 8975; 24 mph; 13.8 mpg; mostly city driving (NYC traffic) with a few weekend jaunts on the highway. I clean things out on the weekend!

 

13.8 for mostly NYC driving sounds about right. I can see as low as 10 mpg a tank if I get caught in bad NYC traffic. I have seen as high as 22 for pure highway driving.

 

We had to pay sin tax for gas guzzlers. At cruise, on any day, 70 mph or a bit faster and up and down a bit on the pedal and up and down hills I've seen 23 mpg and better. I get just about as good mileage as our Edge. It will never see 30 mpg and it has a heck of a lot less power. Vigorus driving well that's something else.

 

16k miles. average 10.8 mpg. hawaii roads & traffic are absolute bs.

 

You must be doing lots of highway miles in C mode to average 20.6 mpg.
Couple months and 2000+ miles is the confirmation.
Last time i did 1000+ miles a month was when i was commuting to work 140 hwy miles daily.

 

I have never even looked at that part of the cluster....why get an AMG if you're gonna be worried about that. That being said, I do go out of my way to actively avoid it at times. lol

 

Mine reads 11mpg for the last 5000 miles. Usually I only average about 9-10mpg in mostly city driving, if I really gas it then it goes down to 8mpg lol.

 

I think its best you don't look at your MPG....it may wipe the smile on your face...until you hit the pedal!

 

Sitting on the H1 for hours doesn't help

 

Those 2000+ miles consisted of a trip from DC to Chicago, DC to South Carolina Motorsports Park and a couple of hours of track time. The rest of it was DC traffic and normal driving.

On the highway with cruise on at 70-75 I usually get around 23 mpg... Driving across the midwest is pretty flat and consistent...

 

Nice. It's awesome that you were able to get reasonable fuel economy out of the car.

 

one thing I noticed is traffic will drop range over 50% if you're in stop and go versus flowing traffic. On my last 2 gallons it will say either 25 miles left in stop and go or 75 miles left in highway speed.

 

Ill add one more thing.. Those trips were done over the winter months, so I had the AC turned off and my all season tires.. I am going to take it out to Chicago and back next month with the stock tires and obviously running the AC... Ill reset everything and see what I get...

 

Pretty impressive!

 

cruising on the H1 I usually get about 13 @ about 70 I dont hit traffic much
yesterday it hit 24 i think it was sick or something stood on it later and got it back down to 10. That was more normal!!

 

I just attended Advanced AMG Academy a few weeks ago and got curious... track mileage for the day in the SLS was 4.8 mpg

 

I'm dying to do one of those events! Was it worth it?

 

"Around town" I get 13-15mpg.

I drove from LA to Las Vegas and back and got 23mpg. Average speed 70mph and most of that was on cruise control.

I swear I got better gas mileage the faster I went. I suspect these engines run most efficiently at speeds of 100+. At least that's what I tell myself.

 

More curious how much you guys spend on gas each month, those who daily their car?

I spend around $1000-1100 CAD for 94 Chevron each month

 

$130 USD each month at most. But I only drive around 70 miles per week and usually walk everywhere on the weekend.

 

I fill up about 3 times a month for the C63, so about $190 on gas for the M156, not including my other cars. I definitely do not DD the car, it would just be frustrating having no use for all that power while idling in bumper to bumper traffic every day. I seriously hit bumper to bumper traffic the moment I pull out of my driveway, all the way until the work place. I should just sell my DD Lexus for a prius

 

Get a bike man. Good mpg and power when needed...c63 for the nice days with less traffic

 

I put on 122 miles each workday plus weekend driving filling up Sunday, Tuesday and Thursday evenings. My gas bill usually runs around $600-800 per month, depending on my travel schedule, on 93 octane. Would love something with similar performance, four door and above 30 mpg. But, I only live once.
