Was wondering if anyone else was running 70mph in 5th gear @ 3k+ RPM?
I ask as it doesn't seem ideal for economy on the motorway to be in VIS...so didn't know if this was normal or if someone had changed the gearing in this car at some point?

Revving this fast would not be normal for a diesel but could be for some petrol models

Sorry, I forgot to add that this is the 2.5L V6 (ZS180)

That's about right. I think mine sits just under 3k.

The VIS mode doesn't really make a difference to fuel economy, plus the throttle position is also taken into account (i.e. the balance valve won't open at 3,000 RPM on partial throttle - there are diagrams somewhere that show the parameters).

I did wonder about it years ago, but settled myself that it's good to have some immediate power available when cruising at 70.
