I think they may SAY the V6 will have 260, but I think it will really have ~300ish. I have the feeling it could be underrated. I also have a feeling the G8's L76 may be underrated but I'm just taking a guess here
because it seems to have some killer performance as the LS3 vette's seem to dyno more HP than expected.
As for me, all I want is the base V8 and I will be the happiest person in the world. Delete some mufflers and I'll be happier.
