Can anybody tell me the actual fuel consumption of his or her Cayenne Turbo or Turbo S? I suppose there'll be quite a difference between what the book says and real life.

I'm about to change my 2010 Boxster Spyder :( for a bigger car due to a baby on its way and a Cayenne seems very appropriate for this. I just want to know what I can expect when it comes to fuel.

Thanks for the help in advance!

I make a 200 mile return journey most weekends and if I stay off the turbos and cruise at 65 I can get 20 with my 2006 TT. My daily commute of 25 miles each way in heavy traffic gives me 15-16. If I want to have some fun and spool up the turbos it will drop to 13. Not bad when I consider my Dodge Ram Hemi truck only returned 13

All UK MPG in a 05 Turbo; I would say I average 16mpg to a tank. I generally get 300 miles to each tank before I fill up. The tank is 100 litres but when I fill up I normally have to put in between 80 - 90 litres to fill it full again. The is some motorway driving at 70-80mph but mostly stop start in traffic (I'm in London).

I have seen as little as 250 miles to a tank but also as much as 375 miles. The most I have ever seen when doing a constant 70-80 for about 250 miles is 23.3mpg.

I have an '06 CTT the mileage in town [ i.e. stop and go driving ] is around 12 mpg. Highway has been as high as 19.5 mpg. If I keep my foot out of it I can usually average around 14 mpg in town . Not bad imo considering my '02 Explorer Sporttrac 4X4 6 cyl. gets 14mpg town and 18mpg hwy

2006 CTT - Best straight flat hwy 75mph 15.5mpg on a single continuous drive from fuel stop to fuel stop with cruise control most of the way. In town mostly 45mph speed limit streets(Bakersfield has great surface street speed limits!) 10-11mpg. And don't trust the instrument panel mpg calculation, mine always shows 1.5mpg higher than actual calculated consumption.

As a point of reference my 7500lb 2001 Ford F-350 crew cab 4x4 diesel does 13mpg city 16.5mpg all day long and doesn't break down every 2 weeks, like the Cayenne has since I bought it 4 months ago. Granted my Cayenne has 95,000 miles but it's pristine like it just drove off the showroom floor. My research so far indicates that all of the plastic parts Porsche is using in the modern water cooled engine bays just don't hold up with age.

same as above.....15-16ish standard highway with slight in town driving. My daily commute involves in town and traffic driving....i get around 13 if i drive like a grandma. As everyone else has said.....if you compare that to really any other america V8....you will get better mileage and SIGNIFICANT performance over basically everything with a select few SUVs.

With that said, there are plenty of good European and Asian V6 and some V8s that get good or better mileage....V6 TDIs are the first that come to mind.

I guess your decision is do you really want/need the blistering speed and power for the CTT or do you just need more space with good interior comfort.

      Hi all I’ve been fighting with the cayenne again 
      let’s me put the key in and turn it then I get steering fault as attached any ideas of a way around this or a reset thanks car won’t start

      Hi Everyone! Long time Lurker and final a first time Porsche owner! I just got a new to me 2008 CCT with 56K miles on it.  I really like it but I am already having several issues with it. The good news is, the dealership I got it from is including a 60 day 3K mile 100% warranty on all parts and repairs.
      One of the several issues I am having is it sounds like the power steering pump is going and it makes a loud whining noise and they are saying it's normal. The ps fluid level is normal, but it is a very distinct noise that I can hear from a distance away. I would really appreciate if you could help me decipher this noise. Here is a video of the noise.
      Other problems are: Needs a new driveshaft. Needs the thermostat replaced. It keeps throwing a 1117 Load Signal Generator Terminal DF. Battery is reading 13.4 max with no load running and drops to 13.0 with lights etc. on. They insist it's good.  Brakes won't stop squealing after replacing pads and they had to replace they front left Accelerometer because of the air lift system error. WHEW! I still thinks it's going to be an awesome vehicle.
      I go back this week to drop it off for 2 days for all those repairs but I want to make sure I get everything that is obvious. Also since they will have the intake manifold off, I was thinking I should replace the Plastic T connectors for the coolant lines. Is there anything else I should deal with while they have it all apart? Ignition coil packs?
      adding this for new readers:
      Thanks for any help guys.

      Hi Porsche people
      I changed the spark plugs of my 955 CTT  yesterday and I think the plug on cylinder 6 is not as the others. For me it does not show a realy scary image,
      and I'm sure it is not urgent but can you see something more?

      Hello everyone,
      This is my first post but I have done tons of forum searching and found similar posts but nothing with my same codes. I have noticed a rough idle but once I drive the car drives great and boosts great. Along with the 2 EVAP codes I have P0300, P0301, P0304 and P0308. I have changed the spark plugs and I did a full inspection of the coil packs. The coil packs looked perfect, no cracks or damage and it needed new plugs so I did Beru plugs. In that process I changed the torque arm also because the rubber was shot. That didn't solve the misfire and I didnt notice any wiring issues or connector issues.
      Onto the EVAP stuff. I have the two codes P2401 & P0448. Just put a new gas cap on and cleared the codes, they come right back. I also checked the oil fill cap and its seal looks great (no cracks in the oring).
      Does anyone have any idea or run into these same symptoms? I have an appointment at my local Indy shop in a few days but would like to go in prepared. They're going to start with a smoke test looking for a vacuum leak.
      Thanks in advance,

      Hey. I'm new to this forum and owner of a Cayenne turbo 2004., I have had the airbag yellow warning light on since I replace the battery. I didn't receive any error code. And I follow the previous post on this forum tried to use the PIWIS to erase the faulty memory, it didn't work though. And I also tried to disconnect the battery, but the light still on. I bought a Maxicheck(it's more direct and easy for me to use than PIWIS) to detected where is the problem which shows control module faulty 3 and belt tensioner, passager's side, rear 4BC. also the actual value shows almost everything is "too big". So my question right now is does it means my control unit need to be replaced? And if I replace it use the used parts do I still need to do the "locking steps"(I saw people talking about the airbag lock in other post). English is my second language hope I can get everything explain well. Thanks for your help.
