Note that GM and Ford have more displacement to work with and generally these engines make peak power at much lower RPM than the S65. By the way, these engines borrow heavily from the light truck siblings so there is cost sharing here just like there is with BMW. And Audi and Mercedes are abandoning naturally aspirated V8s just like BMW is. The 4.2L Audi V8 is being dropped despite its use of GDI, so they see the writing on the wall just like BMW does.

I will say that I wish BMW would have made a case for a smaller displacement turbo V8 for the M3/M4 like Mercedes is doing with AMG.



It's not realistic to expect a company to just abandon standard marketing practice. None of BMWs competitors have stopped extolling the virtues of their products and BMW would surely be foolish to try and compete on those uneven grounds.

Well said man.
