==========
The performance of the TS030 HYBRID is reproduced extremely realistically. I didn't imagine that such a thing would be possible. -Racer Nakajima Kazuki.
Nakajima: I have never played Gran Turismo before, but with better steering and three screens (using 3x 60 inch displays) the field of vision and the sensations were not uncomfortable at all. It felt just like driving a real race car. Compared to the feeling of driving the real TS030 HYBRID there are some small differences, but overall it is very close, including the lap times.
Yamauchi: With the TS030 HYBRID, we were not made privy to all the data, so certain aspects are speculation on our part. Even last night, thinking about Racer Nakajima's arrival, I made some adjustments to the gear ratios and tyres. It also took me some time to stumble my way onto where on the course to use the electric motor and where not to. But I'm very relieved that the lap time turned out to be very similar to that from last year (lol).
Nakajima: Braking points, and the feel of grip in the tyres, and the sensation when turning the steering wheel, these all feel exactly like the real thing. Because the information about the workings of the hybrid system and it's effects was not given, I imagine that it was very difficult. But I really feel that you have done a very good job. There is one thing I might mention. The real car has traction control*, so that's one difference, but that wasn't enough to dampen the experience.
*A system for controlling the engine under acceleration to reduce wheel spin. It makes a driver's job easier, as they can just step on the accelerator. Abbreviated as TC.
Yamauchi: The setting for TC exists, perhaps it would be better turned on.
Nakajima: But driving is a lot less interesting with TC on. Er, in the game I mean (lol). It's true that it's a lot more fun driving without TC though.
Yamauchi: It really is difficult to reproduce the driving characteristics of a hybrid.
Nakajima: But I think that the performance of the car is reproduced extremely realistically. I didn't imagine that such a thing would be possible.
Yamauchi: Because the regulations governing the cars (from last year) are public, we know how much electrical power each use of the capacitors* can output. Then there's publically available information on the time the motor takes to accelerate from 100 to 200kmph, and so the power of the motor can be extrapolated from that. During cornering, we assumed for the sake of argument that if the speed was under 100kmph then electric power was not needed, and so none was delivered to the motor, and so we built our assumptions up in this manner.
*A part serving the same purpose as the battery pack in commercially available hybrid cars. A capacitor is unable to store a large amount of electricity, but it can charge and discharge repeatedly very rapidly, and so is suitable for racing car applications.
I noticed that part way through Racer Nakajima's driving suddenly changed. “He's got it!” I thought. -Producer Kazunori Yamauchi
Yamauchi: Watching Racer Nakajima today, I noticed that part way through his driving suddenly changed. “He's got it!” I thought. With the current settings one wants to open the accelerator at the apex of the corner, but if one waits a little the car will straighten up, and then if the accelerator is pressed further than 80% of it's travel the electric motor will activate. Before that 80% the car has 500hp. If the accelerator is pressed beyond 80%, and the speed is over 100kmph, the power of the electric motor will be added to that. Even though we had not told Nakajima about these settings, it only took him a few laps to perceive and understand that and adjust his driving accordingly. I was astonished.
Nakajima: And then the car's balance under braking...oh, is that because of the regeneration simulation?
Yamauchi: Yes.

Second part to follow if and when I find time, it might not be for a few days.
I make no promises that this is accurate. I'm just a student of Japanese, my native language is English. I've had to look up words where I didn't know them, but I'm fairly confident that this is a decent representation of what was said.
