Sounds better, but still need more work. Upshifts sound pretty bad, and the engine at high revs doesn't go high enough in pitch, sounds like it's constantly short shifting. Downshifts sound much better, trans whine is louder, and the tinny high end sound is improved.
Funny now all the fanboys over there are claiming the new sound is perfect, even though they were all claiming there was nothing wrong with the original sound lol.
Like anything in the game, they defend it as though it's perfect until the devs own up to it being rubbish, and then the smallest improvement and they're all back at it claiming it's perfect again. Jesus that's not how you do constructive feedback, constantly sucking up to the devs like that.
Edit: It's good that they're working on it though. It is probably the least accurate sound in game, on one of the most anticipated cars.
