Similar story on his previous audi s4 wagon. He's always sending me pictures to wind me up!

I'm sure BMW diesel's could achieve amazing mpg on a long run.

What it comes down to is the volvo units are really poor on fuel.

Yeah I’ll blow that with a T6 V90, and the mpg. All smoke and mirrors, plus 6 cyls are dead, at least in EU with new laws. Even the BMW 330i is a 4 pot.

Have you tried not using eco mode to compare the difference? The biggest advantage from the Volvo eco mode is using the kinetic energy in the vehicle by being in 'coasting' mode as much as possible. The you need to consider that in non-eco modes your car is basically using no fuel at all or at least much less than the idle speed of coasting. It is important to make sure your foot is completely off the gas pedal to acheive 'coasting'.

I don't know how much of that is possible for eco mode in a lot of town driving as I don't do that much anymore. You may well find that eco mode is not the best for mpg in town driving; just thinking out loud not saying it is so.

I have a long term average of 35mpg according to the on-board gizmo. That is a mixture of rural driving often in the summer stop/start at sub horse carriage speeds and some town driving. As others have said on longer journeys with lots of steady state driving and max use of eco mode I can average well over 45mpg.

Looking on the US sites there are several who report comparable figures, or slightly worse, to yours (once you allow for the US gln v Imp gln.)

What you show is that motor engineers can't overcome physics.

What you're seeing in town and on a run are pretty much the same as I used to get in a 2.0 petrol auto Xantia in the late 90s and a 2.0 petrol auto Subaru 10 years later.

The "massive gains" in MPG on modern petrol cars certainly don't exist on any that I've hired in recent years - it's just the old thing of the manufacturers working to ensure they look the best under test. If you go back 40 years, many makers would state their car did 50mpg - the small print was that was on a rolling road, inside, at exactly 56mph - something the average bloke could never do so his 50mpg car did 30mpg like all the rest of them.

As for diesel, the consumption of my current V60 is worse than my previous V70 and is worse than a Jag X 2.0D I had on a 59 plate - each one in turn having more restrictive emission control guff which in turn either uses more fuel or causes more restriction in flow.

My S4 Avant (2017 /354ps) did 30 overall with 34 on a run. My 2.0 petrol Golf R estate (310ps) once did 40mpg on a run and averaged 34.

Back to the thread, I would buy a petrol hybrid if driving in London. As above 52mpg demonstrates for a Volvo. My overall mpg would be great if I was doing 25m a day on electric and only using diesel out of urban areas, but it's still at 70+, so despite the weight of lugging batteries around, hybrids are definitely a good compromise...

Ok I am absolutely gobsmacked. Did my first long journey after 8 months of owning this car (London to Birmingham) and achieved 45mpg. I used just under a quarter of a tank. Eco mode all the way, cruise control active down the m40. I am very happy right now lol.
