V70 D5 impressions

I was expecting about 45mpg so mega delighted. The upshot is I can press the loud pedal more often and still return 40+mpg

Coming from a petrol V70 T5 and a V70 AWD R even that's a 25% improvement.

That is very good m.p.g. for a 215 D5.

My 10 year old P2 163 V70 managed 52 on a run, good to see a modern v70 D5 returning near same!

It depends on which D5 you have. The 185bhp is the worst economy wise. The 215bhp is better than the 205bhp, which I think, is similar to the 163bhp.

It's not even as simple as that.

There are two versions of the 205 engine.

From June 2009 to May 2010 is the first version, 183g/km (geartronic) and 40mpg combined. From May 2010 is the second version, 169g/km and 44mpg combined.

The 215 engine is 45mpg combined, 164g/km.

From those numbers, the later version 205 is much closer to the 215 than the earlier version.

I'm assuming the OP's car is manual?

Oh Yes.... I don't like auto boxes, and from comments here I know that there are significant fuel savings to be had by running a manual. So for me its win win

As an interesting benchmark, last week I drove my father's BMW 740iL about 200 miles.

It's hard to consider a nearly 300bhp car as "underpowered", but it's amazing how you get used to the massive torque plateau that the twin turbo D5 engines all produce.

Yep I would have to agree my 185 D5 is thirsty compared to my last 2 163's but I still wouldn't change it, there's a certain love affair and awe of what you own when you've had one for a while.
I miss my v70 but couldn't keep both.

the secret here is the cruising speed of 60 mph rather than 75 mph it makes a huge difference with wind resistancxe although the car feels so effortless at 75-80 mph it is burning a lot more fuel , people don't seem content with sitting at 60 mph on motorways ! average speed would have been over 50 mph too which is hard to maintain .
If he had the 1.6 D he would be up in the 80 mpg region ...

The 2011/2012 D5 215 is actually 124g/km and 60.1 combined and the 2013/2014/2015 model is 119g/km and 62.8 combined in the S60 with the V70 slightly thirstier and slightly more CO2.

Currently averaging 47.1mpg in my 2012MY D5 215 and I don't exactly hang about

I have read somewhere that the 2nd bigger turbo kicks in at approx. 2000rpm, but until then the smaller one gives the engine boost. Hence the fuel saving.
Why you need a large turbo running just to cruise at motorway speed seems daft, and 60/65 is just below the magic 2000 rpm figure. Agree cruising at 60mph is a lot more relaxing than 70/75mph AND you suffer less slowing down (and speeding up) due to slower traffic, AND you don't really save that much time.
