A couple of years ago when we were critiquing the SLS, they showed us a video with the SLS going around a track and our reaction (all eight of us) was utter surprise regarding the great exhaust sound. It was totally unexpected but welcomed. That alone made the car more attractive to all of us.

Why modern turbo engines lack the aggressive exhaust is beyond my mechanical knowledge. In Porsche's case, I assumed they deliberately reduced the sound as a marketing and environmental decision. Or could it be a mechanical issue?
