What's does your Cayenne get?! Just asking to see what I should be getting, some days I get 7mpg if I'm moving around, and others up 10-11 if I'm cruising around. Don't expect much more in a CTT

And what do you get on the highway?

Ive been noticing on my CTT that after changing my exhaust to Leistung SR1 (modified), removing secondary cats (change to Leistung straight pipe set), changing intake filters to BMC, that my street mainly is at about 14mpg, and highway mostly at about 22mpg. Mix of street and highway gives me about 15-16mpg.

Is 22 on the 955? What speed is that at? That's really good.

I have two 2004 s, The totally stock black one gets 17.2mpg. The white one with modified exhaust and K&N air cleaners get 16.6mpg. Most of the driving on both is rural, on long trips (hi speed the faster the better 80+) both get over 18 mpg

Just calculated a trip from Denver to Buena Vista. For those flat landers out there, that drive has a lot of mountain climbs. Filled up before I left, and when I got back. Driving mostly 65-70 mph (65 mph speed limit), WOT during occasional passing, but otherwise standard driving habits - I got 18.9 mpg. I bet I could have gotten over 19 doing the speed limit. I guess I can see getting over 20 if you live where it's flat and only did 55 or 60 mph, but I think 19 is the best I can expect out in the mountains.

When I first picked my CTTS up on the East Coast in '08 I drove from Deleware to Washington state and averaged exactly 19mpg. I did keep it down to 65mph most of the way but did hit some strong headwinds all through the central states.

Currently, 18.2. Best I've ever experienced. Took about 4 months of mostly highway, traffic-free, very conservative (55-60mph) driving combined with light Manhattan, weekend trips. Previously, daily NYC driving, 14-15mpg. 04CS

Here are a few points of relevance for my data.

2006 Cayenne Turbo S

Stock

95 octane unleaded fuel

City driving with local lights often missed.

Area driven zip code 85260 and 85259 mostly

Day driving

DA(density altitude) has been averaging around 4000ft to 5000ft

About two weeks since last reset of MPG, couple hundred miles

Occasional full throttle and driven average with minimal concern of fuel usage other times

Included would be two passes up to 100 mph or so full throttle for testing

11 MPG
