Journalist: I've test-driven a lot of the cars. Modern cars now drive quite alike – often it's hard to appreciate the difference between them. In the game there's always a difference between two cars – what do you do to enhance that difference?
Kazunori Yamauchi: It's really because the body structure and layout of the cars are becoming almost identical that we came up with different cars. For example, if you take the Ferrari 458 Italia and the Ford GT and look just at the body they're almost identical and you can't really tell them apart.
I think it's just that sports cars have evolved to that point now. For the character of each of the cars, manufacturers focus on providing different sounds that the driver will experience in the car, and also the steering and driving feel.
They would treat things like the feel of the power steering and I guess some of the cars have an adjustable power steering feel. There's many cars where, by turning this knob, you have a very different character in the same car.
On the base part Gran Turismo is pretty much the same. In terms of character you'll find of course that older cars have a stronger one. You'll find that especially so when you compare cars with the same power ratio over those of an older era – the difference is much greater in older cars.
