I read somewhere many, many years ago that a 6-cylinder engine (in what configuration, I don't recall) is inherently balanced whereas a 4-cylinder engine is one of the worst, if not the worst, in trying to get it to run smoothly. My experience over the years has found this to be at least approximately true in that, other than the Saab, the 4s have been rather rough running while the old Corvair and the 6-cylinder Porsches run quite smoothly.
