This thread seems to have multiplied at BimmerPost, but here is a point I wanted to make on M3Post as well. Sorry if duplicate.
An award is as great as the quality of its nominees. The S65 was crowned #1 with the following competition:
#1: BMW 4L V8 (BMW M3)
#2: McLaren 3.8L V8 (MP4-12C)
#3: Porsche 3.8L Boxer DI (911 Carrera S)
#4: Audi 4L TFSI (S6, S7, S8, Bentley Continental)
#5: Nissan 3.8L Bi-turbo (GT-R)
#6: Porsche 3.8L Boxer Turbo (911 Turbo)
This is a huge win for the not-so-new S65!
