Bleh. It sounds very characteristic of a low revving turbocharged inline six. Lot's of blaaaaaaaaat sound, very little shrieking like we're used to from M cars of yesterday. Almost reminds me of a high-performance diesel. I sure will miss the scream of the S65.
On a positive note, the driver sure wasn't pulling any punches on those laps. Hard on the brakes and really sticking it through the corners. The suspension looks like it's holding up well. Can't wait to hear the actual bridge to gantry time.
