Hi folks
im in the market for a cayenne. Can anyone tell me the differences between a cayenne and the s model?
What are the extras or other options on the s over the other 4.5 models.

Many thanks.

May be different in the UK but where I live the S is a V8 and the regular is a V6.......
As with all Porsches the spec varies massively depending on what was ordered, and they do not all carry a premium on the second-hand market.

Well, finally took the plunge at last. Been struggling to find the time or the right car for a good few months now.
So at last I found a 4.5, 2005 in grey with air suspension and panoramic roof. Gas converted so pretty good mpg. Goes like a rocket!
So far, so good- at last!

Hi, you are the only person I ve heard of that has an LPG Cayenne. May I ask:

How many MPG now or cost per 100 Miles/kms

Where did you put the tank and does it not render the boot unserviceable?

Being a fellow KN owner I'd love to do it.

A few years ago now I converted my LR Disco 3.9 V8i. I dispensed with the original petrol tank (under the boot) and put the LPG tank in it's place - so no loss of luggage space. I then fitted a 5 gallon petrol tank in the rear wing (fed by the original petrol filler). You only need petrol to start the engine and get rolling before switching over to LPG. You lose a bit of power - not really noticeable with a big V8 - but if I was ever overtaking, I did briefly switch back to petrol so I had the full beans and then switched back to LPG after the pass. When I did mine LPG was almost exactly half the price of unleaded. I think I went from 19MPG petrol to 16MPG on LPG so I looked at this as 32MPG - better than the equivalent diesel.
Hope this is somewhat helpful.

I had it done by Dual Fuel Systems in Woking. Their web site domain is for sale now so perhaps they're out of business now.
There were two reasons I used them - one is that Woking is less than 20 miles from me, and two they used Landi Renzo LPG kits which I researched as being very good at the time (made in Italy). I only ever had one backfire which was completely self-inflicted. My wife used the car most of the time when the children were young but I took it out one evening. The last thing she said to me was that it needed gas. By the time I had started on petrol and got warned up, I threw the switch to gas just I remembered her last words - no gas! It backfired and popped the lid of the airbox but nothing more. It all clipped back OK. I was lucky - I've heard of air filters being destroyed, airboxes being warped, and in extreme cases, bonnets being dented! As long as there's gas in the tank and the engine is warmed up on petrol, you should never suffer a backfire. The Landi Renzo system was sophisticated - it used the Disco's lambda sensor to control its mixture and it connected to the ECU to trick it into thining the petrol injectors had fired OK so there was no check engine light. It cost about £2k in 2001. So I had someone install it but I specified the size of tank, where it went etc, so I had some involvement! For example, on Discos some people keep the big petrol tank and fit torpedo LPG tanks under the running boards. This is OK except they're not in a crash protected zone, whereas of course the original petrol tank is! As I said before, my two children were young and we needed all the boot space possible.
I hope this is helpful.
