4.8 gts or 3.0 tdi mpg and owing

[gothbiker]

Hi I’m looking at buying a 4.8 gts or a 3.0 diesel Cayenne.
I’m off for a few weeks in Spain, so after something interesting to drive.
What sort of mpg in the real world people have said inbetween 15 mpg to 28 for the 4.8. What do people actually get? It’s going to be a long cruise and a few interesting twisty roads!

I have the 300hp 3.0 V6 diesel in a Panamera, Motorway 70 ish does 44mpg - 46mpg, driving slower its upto 48-49mpg. Not remapped or anything.
