Nglitz has quite eloquently expanded on the point I was trying to make. The execution is much more important than the basic design choice. A well designed V6 is going to be a much nicer, more robust engine than a less well done I6. This despite the I6 being an inherently "superior" design. I use quotes because which engine layout is best depends completely upon how one defines the measurement criteria.

BTW, as to that amazing 333HP BMW six, they seem to be coming apart (in small pieces...) at pretty good clip. Try typing something like "bmw m3 engine failure" into google and see what you come up with. Here's a moderately interesting link: http://members.roadfly.com/jason/m3engines.htm
