Mileage report.. '06 CS

[deilenberger]

At an average speed of 61mph, about 900 miles so far - 20.5 MPG. Cruise frequently set between 65 and 75MPH. Not so awful.. :)

I have the V6 and according to the PCM my best average on a 800km trip was 25.5 mpg @ 100kph. But that is also using the bigger gallon.

04S and I have never done better than 18.5 on the highway.

That's a good number.

The Imperial gallon is ~ 1.2 US Gallons.. so 1/1.2 = .83333, and 25.5 x .8333 = 21.24 MPG. I'll sacrifice the 0.75 MPG for the extra HP.. :)

I've got to run it a bit with the PSM off tomorrow AM and reset the adaptation.. it feels lumpy under light acceleration... I think it learned to run a bit leanish.

I can attribute most of that to my wife being in the truck with me.. If she wasn't along for the trip I'm certain I'd be dipping down into the 16-18 MPG range.. ;) Mebbe I'll suggest she wash her hair in the AM (we're in a motel) and I will take the truck to the carwash.. then I can turn the PSM off and clear it's throat a bit.. it feels a bit lumpy on very gentle acceleration around town - usually a few runs up to 5k or so clear that right up. :)

BTW - I haven't seen another Cayenne so far (935 miles).. saw one Panamera today, no other Porsches actually. They really do seem scarce outside the east coast area. Guess when I get to Las Vegas and LA the Cayenne will be a common utility vehicle.

'06 Turbo S from Delaware to Washington state (about 3K miles) and I got exactly 18mpg. I mostly had the cruise control set on 75mph but had some real strong headwinds in the Midwest from Ohio to Wyoming. I did this trip back in the middle of March and hit a mild snowstorm in the Appalachians.

Latest leg (in lovely West Des Moines Iowa..) about 325 miles - combo of highway and sightseeing, average speed is down to 55, miles are down to 18.5MPG.. but it feels smoother under light throttle (I did a PSM reset this AM, SWMBO never even noticed..)

So far - haven't seen a single Cayenne, and I'm almost half-way across the country.. (1,300 miles out of 2,700) - did see one VW Tourag in Amana Iowa - which is a lovely German village made into a tourist trap... but not a single Cayenne on the road. They must be out there someplace.. :)
