The M4 does sound a bit like a fart in a tea pot though and like F1 engines now when an engine has a Turbo it just ruins the noise for sure its just so artificial.
Amazing video ... Having driven an m4 for an afternoon, pretty extensively, still not sure! The noise out if its arse is just so unpredictable. Video just fuels my love of M cars more. I'd love the money for a mini collection.
