LOL @ 00:43 and the AMG turbo whining away. The A45 AMG is absolutely insane.
F80 is sounding decent actually, although as with all turbos which rely mainly on exhaust for noise, you won't hear much action on approach, since turbo BMWs make almost no noise on rev-match downshifting. Load only. Always a disappointment for me, but performance wise it looks to be quick.
For you late model E90 M3 owners... best to hang on for a while.
