Cost rationalization is hard to determine from our perspective of course. But it only seems logical that one engine instead of two, would be a cheaper way to go. That is why the SLK350 will be getting the new direct injection engine - every other line will be getting it too. Maintenance protocols will be well established, seeing as it (the DOHC 5.4) will have been in other models for 3 years by then. With the new V8 powered M3/Roadster/Coupe right around the corner, MB will have to do something to keep the AMG model fresh and competitive until the R172 comes along. But that could be done, like you said, by using the Black series spec engine. It just seems to me that keeping the SOHC version 4-5 years, after it has disappeared in all other lines, unlikely. Especially where there is another readily available DOHC version that is current, and easily capable of meeting/exceeding power requirements.
