The inline six configuration is inherently balanced. There are no shaking forces or rocking couples below fourth order, so if the crankshaft is sufficiently robust to prevent torsional vibration problems, an inline six is inherently smoother than any V6 configuration.

My point exactly, stated more eloquently and in more detail.
Given that the current V-6 is said to run rings around the inline-6 designs in every conceivable manner, I haven't seen any response or info as to an increase in overall efficiency or power generation of the V-6.
I think the benefits of 3-valve vs. 4-valve technology can and should be debated as well.
The bottom line, is that the V-6 engines were conceived, designed and produced to meet reduced cost targets. It's a decision that is in keeping with other MB quality, design and engineering decisions over the past 10-15 years.
Why does BMW refuse to go the V-6 route and maintain its inline-6 designs?
