Tried to post this several times.. forum issues today? Anyway.. 950 miles circuit trip in 33 total hours door to door (lumbar support I love you) to pick-up college boy for fall break and take soon to be college boy to see 3 campuses one last time in my S. Avg. 75-78 mph 95% of the time. Yes, +++ a little in the left lane.. and yes, some city traffic at each campus. on one 4 hour stretch with no break avg. was 20.5 mpg. Bottom line.. I don't think most decent size sedans get much better maybe 25mpg. I'll take the Cayenne, utilitarian use and the power and darn good gas mileage. Pfffffffffffffftttttt to the SUV Haters.. 6 speed automatic is pretty darn efficient<@

I've had my CS for about three months now... Had it into the dealer two weeks ago and mentioned the hesitation issue in the hopes that they would flash my ECU with the latest code. Instead, they say they found cracked coils and replaced all of the ignition coils. The mechanic explained that the coil packs on a lot of Cayennes are cracking down near the spark plug and this is leading to misfires. Porsche has redesigned the plug connector and supposedly fixed the issue.
I have to admit... the hesitation is gone, and I am now getting a full 2mpg higher than I was before the coil replacement! I just took a trip to Richmond, VA this past weekend and averaged 18.5... and that's driving 85-90 a good bit of the way!
Just something to consider...

Michael,
Glad to hear you sorted out the coil replacement and continue to enjoy the car. I wasn't even aware of the problem when I owned that particularly beautiful Cay. FWIW, I averaged 19.6 mpg on one highway trip.

I can get 18+ on the road averaging between 75 and 80 which I don't think is that bad. Of course, it goes down 8-9 when towing the racecar. Our S4 doesn't do much better than that on the highway. We probably avg around 14-15 in town but I really don't check it that religiously...

Doug,
I am still VERY happy with the Cayenne! And, the hesitation wasn't really a problem... I had just read of some guys getting a ECU flash that seemed to improve performance and wanted the dealer to ensure that mine was running the latest code. When they told me they were replacing all the coils, I was really surprised. But, the wrench at my local dealer says that nearly every Cayenne he checks has cracked coils. Just wanted to make my fellow Rennlisters aware of the problem.
BTW... I just ordered a set of Fabspeed cat bypasses for the CS!
I'm going to try a DIY install... I'll let you know how it goes.
How are you enjoying the 993??
