The S54 and S65 are two of the best motors BMW has ever produced. There is a reason why the BMW MotorSport name is associated with both of these powerplants. They are the best 6 cylinder and 8 cylinder motors in BMW M production car history in my estimation. The S54 is the last true 6 cylinder to follow the M philosophy and the S65 is the last true 8 cylinder to do the same. We will never see motors like them again from BMW. They are the pure, undiluted, true interpretation of the ideals M once placed above politics. Sadly, economic and political pressure forced BMW M to abandon these types of motors which once were the pride and joy of BMW. Real joy, not the BS marketing campaign.
Ultimately, we as enthusiasts love these motors. For myself, I was drawn to BMW because of their motors in particular. Not to mention the incredible chassis and transmissions they are mated to, but these motors were the heart and soul of the M experience. This leads inevitably to us as enthusiasts sitting around and arguing for years on end as to which is better. Some of these enthusiasts have even suggested that BMW should have not abandoned the I6 for the M3 and the V8 was a mistake. Basically, it boils down to, which is better?
Read this if you're interested. This is a pretty great insight for any M owner.
