this is a contest to see what numbers for mpg are possible.

hopefully someone will pass 20's

23.8 on 100m trip after pickup - avg 59mph on country roads
down to 18.4 now and heading south as it nears the 1000ml break in

OK, first things first before we get to far along.. Are the mpg numbers based on the numbers of the ECM (computer calculated) or are you guys hand calculated you fuel mileage.

When you post please say if you are posting your displayed fuel or hand calculated.


Thanks, Troy

I got 21.9 on motorway trip (120mile), avg 85mph on cruise. 700 miles on the odo.

But I've a feeling UK gallons are different than US?

you know you are on an AMG section correct? Smart cars are about a half page down j/k

With my e63 I have never passed 21, dont know about the c63 but I usually average 18 on the highway and 12 on the street

as I asked before,

Is that the cars computer or hand calculated?

after some highway driving this afternoon....


i am keeping a log on mpg's, so i'll follow up with hand calculations on my next fill up. so far i am averaging 16 mpg (per the computer) during break in.

i didnt buy it expecting it would get 20mpg, i'm just curous more than anything.

thanks etowns. hey when u post again do u think u could snap a shot of your instrument cluster at night with the lights on? i cant find any pics of that

check the C63 in HONG KONG Thread


the dude posted pictures of the instrument cluster at night

I get about 20-21 cruising at 60mph for 30+miles on the car's computer, on average ive been getting around 15-16 combined.

But, i get about 7-9 driving how i like to drive on less crowded streets!

Has anybody checked yet to see how accurate is the factory millage computer compared to hand calculations? Example, computer says 20.2mpg, hand cal. tells you 18.9mpg.

From the trip computer

2007 E63 P30

from 95037 to 91355
23.7MPG at 70MPH Average
return 93313 to 95037
this skips the mountains north of LA
23.8MPG at 76MPH

Trip computer!

Town driving 16mpg / Highway -out town 22mpg.

ya i get 10.7 mpg lol either way i drive i had my car for a lil more then 3 weeks and i fill u every dam day i have 2100 miles on it already...and today from drivein around i got 7.9 this sucks

xtinanoel, so im guessing youre pretty much pedal to the metal all the time

kinnda but even when i leave it in c mode i stil get like the most 12.3 mpg its so bad lol

ouch with mpg like that i think i'll have to opt for the m3.

i used to like the c55 over the e46 m3, simply because it was more comfortable and seemed like a better daily driver.

yet strangely enough, now it seems that the c63 is too much and the m3 is just enough

Test drove a demo M3 the other day. The dash was showing mpg in the mid-high 8's. I don't think you're going to be picking up any hippie chicks in either car.

By hand calculation I got 16.7 on my 2nd tank of gas. 75% freeway at speeds of 70-80mph and plenty of stop and go, with A/C on. 25% surface streets. After a few more tanks I will compare that with the trip computer's calculations that have been accumulating since I got the car.

In my first 2 tanks I went about 225 miles before the low fuel light came on.

Not the greatest range, and it's a gas guzzler, but I love it.

26.3
