All I can say is BMW had better not f**k this up. The enthusiasts they would lose will never return. I'm glad I bought an E9x M3 when I did.
My opinion is this gonna be some bored and/or stroked out N54. Not called an N54 of course and of course turbocharged. I'm almost positive it will be 3.5 litres because it's a legendary number and has cache' with us from the M1 and first M5.
