Mr Metcalfe had this to say about the granturismo in the Evo long term fleet:

"...Joining the M25 the snowy conditions soon disappeared, but I’d forgotten all about having selected Ice mode and merrily made my way along the M40 with it still engaged. In fact it wasn’t until I was on my way to the office the next morning that I realised what I’d done – and noticed that my average mpg had risen to 24.5mpg, some 10 per cent better than I’d ever seen before.

I can’t believe the fuel saving is all down to setting off in second gear rather than first, so I can only deduce that switching to ‘Ice’ also introduces a different engine map. To make sure it wasn’t a fluke I left the mode engaged for another 1000 miles and, sure enough, the result was a steady 24mpg-plus. I don’t know if this works in other cars, but with fuel prices the way they are it might be worth a try if you carry the same meanness gene as me!..."

So... reckon this would work in the RRS?!

On the RRS it cuts throttle response, so you'lll yourself if you try pulling across traffic in GGS Porsche Cayenne S Diesel 66 Plate

I nearly have a childish accident everytime I want to set off in a hurry from standstill.

Don't think I have the gonads to keep it permantently in snow mode......

On this subject though has anyone worked out a way to make the TDV6 RRS jump off the line like a scalded cat? I've wondered about having left foot on brake while increasing revs then just lettign go of the brake but never been brave enough to try it....... don't want to brake anything and then feel a prat  Current: I can't say...Oh the Shame!

Sand mode does that, well its not going to worry a X5 or Cayenne but it is faster off the line. Porsche Cayenne S Diesel 66 Plate
