Personally, I really miss the screaming hell beasts of yesteryear. With the V10s (and still the V8s), it created this all-encompassing bubble of sound. When it approaches your seat, it sounds like an angry hell-beast that's coming closer and closer, while you can't even see it yet. When it passes, you are in this bubble of sound in which nothing else exists but the raw power of this Formula One engine. When I read that people are now able to talk to each other, it means that Formula One has lost its all-encompassing 'nothing exists but this car' power and that's a real shame.
I do like that you can now hear more parts working, like the brakes and the tire screeches. It feels more mechanical.
Of course Formula One is still (one of the) pinnacles of motorsport in the sound department, but it is definitely not on another level anymore. It has turned from this otherworldly hell beast into a grizzly bear, or from Dragonball Z into MMA fighters: still something formidable, but just not the same.
What do you guys think?
