5.2 is the same 0-60 time as the Cayenne Turbo, which jives with my experience test-driving a Cayenne Turbo (it felt fast, but no more so than my S3 4.6is)! Of course, the NEW Cayenne Turbo S now has 520hp and does 0-60 in 4.8 seconds, and I don't think I'm ever going to get my X5 to do THAT, but still...the Cayenne will never look as good as an X5, either!

As for gas mileage, after half a dozen tankfulls, my city driving is consistently coming in at 10mpg. That's not the cars fault; it's my tendency to keep it in "S" or shift manually (it's just too damned fun!). Still no stats for highway driving, but I expect that will be little different than stock, since it would be mostly in 5th gear, and supposedly the supercharger doesn't directly hurt gas mileage much.

do u think the 5.2 time for the Cayenne turbo is probably the BEST time wit a real good launch on a real good day cuz ive read in some places that the cayenne turbos time ranges anywhere from 5.1-5.6? what do u guys think

Good question; I'm not sure how magazines, manufacturers, etc. decide on the single 0-60 times and other such stats they publish. I assume manufacturers try to use the "best" times (for obvious reasons), but I would think magazines and other testers would do multiple runs and use an average of them (then again, if they're trying to show the vehicle's FASTEST or BEST time, perhaps they DO use the best one they get). Anyone know for sure?

In my case, I did three runs yesterday, and used the best of the three. I'm a novice at this kind of stuff (I've never even had a car on a track), so I figure my "best" is probably still several tenths slower than a really good driver could get with numerous tries...
