This isn't an attempt to sound smart, this is straight from Roundel.
I do not think the Roundel atricle is saying the new M3's V8 is the same one used in the E46 M3 GTR. (That would be dead wrong. The new V8 is based on the V10, which also has nothing to do with the M3 GTR motor.) Instead, the article is simply saying that an M3 with V8 power has already proven itself in competition.
