It might be because GM is synonymous with the small-block V8, while BMW is similarly synonymous with its straight-6.They've been doing this since Day 1, and it has never made sense.
No M3 review ever written has talked about how much better it would be with the M5 engine. They just talked about how much better the M3 was than everything else in its class (until the 4BW came along). Yet EVERY 4BW review mentions the 5BW.
