If you Play Games Like Rallisport Challenge, Pro Race Driver, V Rally 3, They All have that gear whine, but not as clear as gt3...Since its in so many games..i guess it is real.. I read somewhere online that PD Went out and Recorded Almost all engine noises you hear in gt3 except the F1 cars, they didnt even get to drive the f1 cars to gather data, they used data from all the other cars they got an put it together and said it should be just right, i read that in an interview somewhere online a while back. If you play sega Gt 2002, the comaro, Wrx, and many other cars sound like they do in gt3... i've driven a real Integra, they sound like they do in gt3 imo...the mustang sounds deep at low rpms, the fto lm just sounds beautiful...but i guess no game can ever duplicate the sound of a real engine like a movie can, like when you hear a person talking in game you just know its a game, but in a movie, sometimes it fools you...you think someone around you said something so you look(yes i know its surround sound, but you still know the difference between a game and real life, but sometimes get fooled by a movie). i guess we'll just have to wait for next gen systems to get that kind of sound in a game
