I have just purchased a Cayenne GTS.

Around town I am achieving 21 to 22 mpg. On a 80 mile run last week of mostly motorway driving I averaged 26 mpg.
Given its a V8 petrol I am quite pleased with this.

I was thinking about a Diesel S but the long waiting time was not acceptable.
The dealer said I can borrow their Diesel S for a couple of days and that will interesting to compare.

I am loving the performance and looks of the GTS and I think it will take some beating.
The exhaust noise is spectacular......

 

I recently passed up a GTS for a V8DS order so am interested to get your impressions of that V8DS vs the GTS...
