On my drive up to Chicago my highway mpg was over 25 mpg. I was surprised it was that high. Anyone else achieve that??

 

On my recent 400 mile road trip I averaged 23.8 highway, often cruising at speeds in the 75-80mph range, AC on, with only around 1K miles on the clock. I didn't use CC because I wanted to keep varying speed while still in the break-in period. Once the car is broken in I can see how 25mpg or better would be pretty easy to achieve, maybe significantly better if I used cruise and drove just a little slower.

 

@ 80 i get 24 with the v6... i did 1200 mile trip the first week i got it with 800lbs of stuff in the car and got 23.something average.

 

On the '05 CS P!G never seen more than 14mpg. On '11 CTT P!G have gotten it to 20mpg, I think, by driving it the way Riley "loves" it

 

My 04 S got 19 on the dot on the drive from Austin to Denver with lots of cruise control and a trip average speed of 64 MPH. Man, those small towns in northwest texas slow down your average.

In daily driving, I'm a combined 15MPH.

That is a big jump in efficiency, the new models getting about 100 miles more per tankful!

But I would need a lot of tankfuls to make up for the difference in purchase price of $18k vs $80k.

 

At 6800 miles my average mpg is just over 20 mpg and that includes a lot of city driving and sport mode.

 

 

Guns N Roses...nice

 

i would say my mileage was on highway just cruising between 80-90, maybe a lil faster..

i DD average like 19 and thats sport mode, city driving with highway bouts... auto off is for sure OFF!

im so proud of pop's up there!. lolol..

 

Florida highway patrol must be a lot less numerous, or attentive, than CHP's.

 

I'm getting close to 25 on the highway too. Actually pretty remarkable.

 

I get slightly over 22 on my 2011 CTT (but that is with a Fabspeed bypass). I am averaging 19.9mpg on both suburban and freeway over a period of 900+ miles.

 

+100

 

Get about 23 with my S at highway speeds. About 12 pulling a 911 with open trailer ~ 4,300 lbs.

 

The mpg on new Cayennes is impressive. I can get a little over 25 mpg freeway on my 6000 lb turbo diesel Touareg and around 18 mpg in town. But the numbers you guys are reporting for V8 gassers is awesome. Makes me wonder why anybody would opt for the V6.
