Just trying to get a feel but it seems since the temperatures have dropped, my supercharged is averaging 9.5 mpg ?!? Unsure if thats expected or exceptionally high. I reset weekly and all my mileage is local as a guide..

Whats yours at the moment ? (Regardless of model just curious) Why?.. Because i can....

Tdv6, only had a couple of weeks so can't comment on seasonal difference in mpg

On the motorway coming back from collecting it I was getting 32 which I was pleasantly surprised by, over the last couple of weeks this has dropped to 20 as its all short journeys around town

Will be getting it remapped shortly so hopefully this will increase it a bit

On my TDV6 i get 27 on motorway and roughly 21 - 22 on short runs  2.7 TDV6

17.5 around town,really.! what you do,switch off engine and roll down hills

I usually see a drop of a couple of mpg in cold weather. I put this down to the FBH running on short journeys. About 20mpg currently.

On longer runs, I expect to see mid/high-20s in my TDV8 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

2.7 TDV6, last reset 1000+ miles/5 weeks ago, done about 70% motorway 30% town driving since then, currently showing 28.6mpg.

2.7 TDV6, currently showing 26, reset last fill up, about 75% dual carriageway, the rest local.
I have an EGR fault code showing so will be blanking soon, hoping for an increase.
Then considering Autolgic or BAS remap for further gains
Would be interested to see replies on this thread who have remapped, what gains they've got and with what map

You all should get better fuel economy in cold weather as all internal combustion engines run more efficiantly on colder densor air, that is why intercoolers where introduced,even petrol engines like colder densor air. 10 TDV8 Santorini

Wow.... almost double my current ! I've found turbocharged petrol cars to me more economical and quicker in the cold weather, but never found the same to be true with N/A engines, and this is my first supercharged engine.

Only one supercharged figure so far ? Why?.. Because i can....
