Im not asking which is the better here but what are the differences? Im doing so because my R reg V70 appears to of had another T5 engine from an 850 fitted as it feels a lot different in its power delivery compared to my brothers R reg V70 T5.

Am i right in thinking that the V70 was 240bhp and the 855 was 225bhp? Am i also right in thinking that the V70 was mapped differently to give a more progressive power band compared to the 855 which is sort of all or nothing and how my car seems to spool up?

Where there any other differences too?
