I had another go at the cars...they actually do sound more accurate. I really like the FZ5 where if you rev it at 100% throttle, back off, then get back on it at 100% again, there's that surge in power you get from a responsive NA car. This wasn't there in U30. However, in turbo cars, the turbo whine (whistle) is much too loud i reckon. I was in a turbo car just today and the wastegate is louder than the turbo whine. Re: the UFR, it sounds very strange. As aforementioned, it sounds like a UFO or some sort of futuristic spacecraft. I think because you can't hear each individual cylinder firing, rather just a continuous sound, it doesn't make it sound like a car anymore. Just something i noticed.
