Is a big part of the pleasure, of the joy to attend to a car race.
It fills your senses in an intense way.
The sound of a diesel like this is astonishing in temrs of silence, which is sad if you compare it to the melody of the Aston Martin LMP1 for instance, which sound like a Jet!
POY made a soundfile, and I hope he will be albe to post it.
Best, my friend.
