I’ll just add that I have the 148HP version of the 2.0 litre diesel in my Alhambra & over the 2 1/2 years I’ve had it the average is 41 mpg, but I have done a fair bit of fast A road & motorway which pushes it up a bit compared to twon driving where it’s also in the 30-40 mpg range but a tiny bit better than the 184 HP.
Previous to the Alhambra I had a Citroen C4 Grand Picasso that averaged 53 mpg over the 3 years on a 1.6 l diesel, but same driving type, distance on motorways, fast A road & only some town driving.
