D4 - late V/XC 70

Back to your question though, in the run-out years for the XC/V70 (2015MY & 2016 MY) the cars had two engine/gearbox combination.

AWD cars - 5 cylinder Volvo engine and 6-speed auto (D3 & D4 = 2.0, D5 is 2.4) harks back to the D5 intorduced in 2002.

2WD/FWD cars - 4 cylinder 2.0 Volvo VEA diesel engine and 8 speed auto (D3 & D4).

All are very good and reliable, but as you would expect the later 4 cylinder engine and 8-speed gearbox gives more refinement. The 4 cylinder D4 engine is also ultre reliable but make sure its had the EGR recall work. The P3 platform is fairly solid, no major issues, not quite as robust as the P2 but nothing else is....

The VEA D3 has a 6-speed auto. Not sure why. Cost, perhaps. It's still a good box, however, at least in my wife's V60 D3.

It's probably better to get as late an example of the VEA engine as possible so as to ensure that there is no risk of high oil consumption due to blocked drain holes in oil control rings. Not all early ones suffer from this, but my wife's V60 D3 does and my own V70 D4 has started to show signs, although it seems to have backed away from it after asking for two half-litre top-ups in quick succession a couple of months ago. Volvo redesigned the oil control rings with larger drain holes so as to fix this.

I know some D4's are variations of the 5 cylinder D5, are the late D4's the original versions of the engine that's now powering the V90's?

I know and trust the D5 in the P3 cars, would I be making a dreadful mistake with a late D4? Are the late P3's hiding any problems not shared with the earlier P3's?

I think I've now got what I was after - the late 4 cylinder D4's are the same basic engines as the V90 - and the late P3's are not really any more problematic than the earlier ones (other than potentially higher oil usage in the VEA engines).

On the later models (i.e post 2010) the 4wd system is also engaged when setting off and at some other times.

The AWD cars all had 2.4L 5 cylinder engines in varying states of tune depending on the badge.

My mistake & apologies - you are correct - same also I believe in the XC60 (i.e. the pre 2015 MY D4 AWD is a 2.4)
