There are many things the M5 E6X platform is about...one of them is NOT drag races. Thus, predictable outcome. Anyone who has driven a BMW with the S85 engine knows the engine is absolutely epic above 7K RPM, and (relatively speaking
) ho-hum below that. The S58 is the ultimate expression of the M-racing engine/high RPM NA motor. This does not (IMO) make it a great DD, but it should be respected for what it is.
