how many miles to the gallon is everyone getting?

im coming from a cls 63...i was lucky to get 11-12 mpg...usually i got 10 mpg if i drove in sport (which was most of the time)

 

2009 Carrera S. 23.7 mpg consistantly according to the on-board computer. That includes brisk open road driving and stop and go driving in and around town. Car is just over 5K miles old.

(EDIT) sorry didn't notice what you were driving now; Congratulations!! Your mpg with the PDK will probably be a little better than mine.

 

'09 C2S 6MT-First day I owned it I put 1100 highway miles on it and getting 22mpg at 85 mph.
It now has 4500 miles on it and the milage has improved to 23.5 mpg, more or less.
It's the most fuel efficient auto I own.

 

2009 C2S PDK, with a bit over 3000 miles. Overall I'm averaging a bit over 23mpg (split about 3:1 highway:city). On a recent trip from DC to Norfolk, VA (around 200 miles) I managed a bit over 29mpg at an average speed of 72mph.

 

I am getting about 20mpg driving on back roads mostly. The car has almost 3000 miles.

 

18 MPG here, but all back roads. And I have somewhat of a lead foot... I didn't get a Porsche for the good gas mileage.

 

wow...im psyched that it is soooo much better than my cls

When someone asks me why i bought a porsche i can say because i wanted to go green!!

 

If you are relying on the PCM to track your mpg you may be in for a surprise. I recommend noting your mileage at your next fill up, then note how many gallons you put in, and then at your next fill, calculate total miles divided by the gallons you added last time, and do this for 3 or 4 fills. You may be in for a surprise.

In any case, with my 2005 SC'd 997 (includes larger fuel injectors) and 530HP I get about 14mpg in nostly stop and go. That's down from about 17mpg pre SC, so not too bad for the extra 175HP!

+1... My PCM shows 18 mpg but I'm actually getting around 15-16 mpg. This is mostly stop and go and back roads. I've put about 2000 miles on my used 2006 C2S.

 

On my 2006 C2S, PCM showed 25+ MPG when I drove 860 miles between Seattle and Norcal. Since then, I've averaged around 16 MPG in town.

 

i would say 26-30 if i cruise in six gear, but if I'm going hard 14-16....

 

Round about 19.2 mpg with lots of city and slow traffic.

 

my 2006 averages 15-16mpg

 

I average 17mpg...

 

I got 25 once on a long highway trip. Other than that it's around 16. I get in the car intending to just take it easy, but it makes me mash the throttle every time!
