Chugging around locally I've been getting 33/34mpg on mostly <15 mile round trips. Trip to Devon last week showed 44/45mpg for the outbound journey which was around 110 miles of motorway plus around 25 miles of slowish A-roads. A week of short trips followed by return home showed 40.8 overall. Not as good as I'd like, but that's the way it is.

Ive had my 2005 S60 D5 a week now. Its the 163bhp version non dpf. Currently using it to commute to work over the winter months and beyond. Im averaging 57mpg which i think is excellent for a medium size saloon car. Its the 5 speed manual gearbox. Im super impressed!

Volvo C30 2008, 2.0d, 220,000 miles. Average 42/43 mpg mixed driving.

I have recently changed cars, joys of ULEZ.

37.5 mpg 2009 D5 on a 25mile commute (80% 60mph motorway/20% stop/start)

43.6 mpg 2016 D4 DrivE on same commute

Was hoping for more out of the D4, it seems a bit of a low improvement considering the cost and complexity of all the eco stuff. 8 speed gearbox, stop/start, eco mode etc.

I have a V60 D6 Twin Engine, PoleStar 'engineered'.
Have covered around 15000 miles since acquiring it around 18 months ago. The trips were reset at purchase and the MPG currently sits at 61.7 mpg.
Local operations, around town, are all done on 'Pure' between 3 and 20 miles each time.
Main journeys are up to 40 miles round trips, partial 'Hybrid' but 'Power' at speeds above 30 mph making a lot of use of 'cruise' close to relevant speed limits.
Occasional journeys of up to 300 miles round trips mainly on motorways and major A roads: average of one every month.
Cruising on motorways and watching the 'instant' mpg figure shows anything between 30 and 140 depending on the up or down gradient.
Over all this vehicle is costing me significantly less than my previous vehicle (1.6 Diesel Renault Grand Scenic).
If I get carried away and release all those horses under the bonnet it is a relative 'rocket ship' but knocks that overall mpg figure down by 1 or 2.
I find that using the 'cruise' and letting the computer control the pedal and gearbox optimises fuel usage and selecting 'Pure' around town is better than the default 'Hybrid': the slightest over pressure on the pedal wakes up the diesel unnecessarily. If a real acceleration is called for in Pure the diesel still kicks in and gives one a kick in the backside!

I did a trip from home in the Peak District to Heathrow last week. 60.6mpg taking it a steady 60mph on the M1. The road was quiet and I was very impressed. MY2016 Volvo V70 D4 VEA engine Geartronic.
