Next gen' M3 will be, once again, with 6 cil' in line engine under the bonnet, but this time with turbos. I was very suprised to hear this from turbo engine! Noise is really "race like"! Don't know about you, but I really like the sound!

Future RS 4/5 will also be 6 cil' (V6) bi-turbo, hoping for this kind of "engine voice" !
