Bill Auberlen, current M3 GT2 driver and previous BMW aerobatics practitioner, takes us to a magical place. This is what it sounds like nestled in the cockpit of a McLaren F1 GTR, utterly enveloped in that howling V12.

This video popped up on Axis of Oversteer the other day and we can't get that unbelievable sound out of our heads. We doubt that the other folks at BMW's travelling Oktoberfest, this year at Barber Motorsports Park, have had it much different. Can you imagine a race-spec McLaren F1 tearing into your rear-view mirror?

Is it a wail? A howl? A roar? Listen to this platonic ideal of an engine note and decide for yourself.
