That seems to have given Peugeot the idea that it should revive the ’40-something’ badge a couple of years after they dropped the 407 and 607 in favour of the 508 and build a new coupe, this time a four-door.

Listen: Upcoming Ford Focus ST to employ sound symposer

While BMW employs a digitally sanitized/perfected sound file to give M5 owners the proper sense of aggro urgency when motoring at pace, Porsche went a little more organic with its employment of a sound symposer to feed the 911's flat-six growl into the cabin of the extra-refined 991.
