Driven a S80 V8 AWD - not a bad car, typical solid Volvo - better than the first generation S80s (up to 2006), and certainly more poke than the T6. Certainly better than a Ford Focus

I'm informed this engine is fitted to the Noble sports car, and with the aid of turbochargers gives 650 BHP.
Should I believe this?
The same source tells me the engine is made by Yamaha.
Correct. the same V8 is in the XC90 V8 too - they are pretty bomb proof.
I also have an XC90 D5. I've done 240k miles in it from new - so if you have any questions let me know. The Tax bands changed circa 2006 - 2008ish so be careful to check which ones you look at. Volvo got caught out a bit - so the early ones like mine is about £295, (163 & 185 bhp), they then went up for a period of time until the managed to get the emissions back down under the 500 quid level.
AWD is a common weakness - not much else tbh. Improved on later ones and easy to check if it's OK or not.
The D5 is a strong engine. 2.5T petrol are rare, but also worth looking out for. Avoid the 2.9 T6 - gearbox issues are gauranteed. The 3.2 is strong, the V8

would be the one to have - but they are rare too.
I'm on this forum too (same name

) - do a search and you'll find plenty of info

I've driven the V8 S80 - same engine as the XC90 - luuurvelly - went like a stuck pig.
