The sound of the inline 5-cylinder engine was unmistakably genuine. It was like a scream: Brrruuuup, bruuuuuuuup, brrrrrruuuuuurruuuup!!!... skidding and accelerating. When the crowd began to listen to the Audi Quattro, silence fell. Those who remember the Quattro undoubtedly remember its sound. Unique, legendary. It was like a symphony, perfectly tuned and refined at high revs. No other engine sound has reached that level of musicality. Michelle Mouton dixit.
