Gran Turismo 6 general Physics Discussion(as well as video)

[oink83]

hello guys. tell me why the rocket doesn' t drive as it drove in the silverstone demo. PD changed physics? if this is true i' m really disappointed

It's being suggested it was on some racing soft tyres, therefore very high grip levels.

Just a shame there isn't a more realistic reaction to the very high grip levels the tyres offer.

I hope it's true. But like fabio93bg, I find the cars more "grippy" in the E3 demo than they were at Silverstone. I was waiting for a good video with the Audio Quattro where I could see how hard it is to not loose the rear, but I only saw understeer for the moment

What happened to the :
- "the cars were much more sensitive and jittery"
- "you had to be much more gentle on throttle and careful with steering input but the smoother you were, the more reward there was"
- "With a wheel and pedals, GT6 demands as much from you as hardcore PC sims GTR 2 and rFactor"
?

yes it is what i mean! it seems another thing than last month! i saw a video in another thread showing the rocket and other cars, and the rocket using sport hard and no aids drove clean (just like in Jordan' s video)

 

[szejok666]

It looks like the default tires are set on the same pattern as in GT5. That means they are too grippy. Audi S1 to feel realistic should have sports hard as max. On racing hards it grips like modern race car.

 

[Fong74]

Just a question pointing towards the tyres:
Is there any offical or at least reliable info on what the "10" means one can see beside every tyre-wear indicator in the videos? As wear seems to be off in most videos anyway and the number doesn't change, I was wondering what it could be? Pressure maybe?

Additionally: is tyre wear analogue within the new five segments of the indicator or will they pop off once every 20% are reached?

You may want to watch a few videos of quattro's on tarmac. They can understeer a fair bit (I've seen more than a few running a Castle Combe over the years.



The video above showing that its mainly out of only the slower corners that the rear will step out with throttle abuse, and in the faster stuff its a neutral to understeer balance.

 

[Cosbuster]

I'm surprised on how composed the monster appears to be. Although, I still wouldn't want to be inside on gravel roads.

I totally agree with you on that but you can see on the video that the driver is gentle with the throttle in the corners. On the E3 videos you can see that "everybody" is at full throttle in the corners and the car still doesn't want to oversteer...

I wasn't expecting something like that :



because this car is a RWD whereas the Audi is a 4WD, but I wish I wish we had a little more of oversteer...

( not sure of my english here if someone can correct me )

 

[ICEMAN_ZIDANE]

Just look how these guys Drive, they arent pro's. Most of them used Race Tyres...

GT + Wheel + Comfort Hard Tyres= AWESOME

Why would a 4WD Rally car oversteer?
They tend to understeer, due to the extra drive to the front wheels

 

[Exorcet]

Cars don't just have one reaction. Anything can anysteer.

 

[poumpoum]

Cars don't just have one reaction. Anything can anysteer.

Yes exactly ! For example, I drive my little FWD on track days and if I drop the throttle too quickly on long corners my car oversteers a lot !

With an Audi Quattro S1, I assume that if you are not gentle whith the throttle when you are going out of a corner, the car should oversteer a lot...

If you are not gentle enough, this is what happen (and I think that he's using racing tyres)

 

[CoolColJ]

FWD can oversteer, I used to drive a souped up Nissan Pulsar, so I know first hand
Mostly from the pendulum effect coming out of tight turns, coupled with forward weight shift
And torque steer... but certainly no power on oversteer..

But full time 4WD is different, you mostly get understeer or 4 wheel drifts
At least in my Subaru Impreza. I've never gotten any oversteer moments in it - it's point and flatten the throttle and it rockets out, full of confidence, or washes out wide in a 4 wheel drift
And I'm using some cheap, hard tyres, that are good for making a lot of noise and sliding

The difference in feel, and confidence between the two cars is like night and day.
You really do feel invincible in a full time 4WD car, like the Impreza
The even balancing of torque and engine braking among the 4 wheels, along with the front wheels pulling you out, with the rear wheels pushing you through the turns makes it so

 

[ShiftingGears]

Exactly, the reason there's so many videos of Quattro's powersliding more than any other late Group B videos is because if the drivers didn't force them into a slide, they would understeer viciously. But that also depends on the tyres available.

I think it's probably safe to say that there are some differences between the 4WD systems in that Quattro and the ones in any relatively modern Subaru.

Street Subie would be relativiely simple 4WD system, probably not much different to a high tech group B car. No active torque shifting going on here

Which would mean a GTR or Evo might prove an interesting point of comparison. But that's trying very hard to leverage the advantages of the layout and quashing its drawbacks by adding cost, complexity and weight. Certain electric cars are similar. But I have no idea what this discussion was about

 

[Ills1999]

I think it's probably safe to say that there are some differences between the 4WD systems in that Quattro and the ones in any relatively modern Subaru.

There are so many variations of fwd/awd systems under both the Quattro and Subi banner that would account for the difference aside from 'modernity'.

 

[Imari]

No, probably no active torque. What about limited slip diffs? A low spec Subaru likely won't have them. The Quattro? Looking here (http://www.awdwiki.com/en/audi/) it appears to have been entirely open with optional locking centre and rear diffs. What they put on the race car is another question, but a locked rear diff would explain the chronic under and over steer.

I seem to recall the Quattro had the engine way out the front too, which wouldn't help matters.

I wouldn't get too hung up on trying to compare your Subaru with an 80s race spec Quattro. They're just not the same.

Never assume.

Initial balance on most 4WD cars will be understeer on heavy throttle. the load is going backwards and the torque at the wheels is split four ways rather than two (reducing the chance of power overwhelming the grip level - the main reason why you would use it in the first place).

As has been said in the video I posted (and if you think that's being driven carefully I do have wonder if you watched the same one I did) you can see Scandinavian flicks and/or the handbrake being used to initiate almost every incidence of oversteer. On the longer, faster corners understeer can clearly be seen to be the natural balance.

Wow, I actually didn't notice the flicking at first but yeah, he really does.

SIMHQ E3 Impresssions

http://simhqmotorsports.com/wp/feature-e3-2013-recap-part-i-gran-turismo-6/

Cueing up to give GT6 another shot in one of a dozen sim-cockpit “sleds” Sony brought to the show, Chunx and SeanManly gave the new-for-GT6 Willow Springs circuit a workout in an variety of new-for-GT6 vehicles: the Audi R8 GT3, the BMW Z4 GT3 and the Nissan Delta Wing prototype. The Audi R8 and BMW Z4 GT3 cars drove very nicely, with a lot of understeer if you over-drove them into corners and power-on oversteer if you pushed them too hard out of the corners. Spins and tank-slappers were quite easy to induce with the aids turned off. There was a touch of the tail-happy turn-entry oversteer from GT5, but much more toned down than before, with differences between the cars. Hands’ down, the sweetest driving candy of the GT6 demo was the Nissan Delta Wing. The open-cockpit prototype lived up to the reputation of the real world car: lightweight, responsive, and nimble. And without a windshield, there was no sun-glare issue to deal with.

One of our most enjoyable and lively interviews of E3 was our 30 minute session with Taku Imasaki, North American Producer for Sony and GT6. Taku was very interested in our line of questions, which favored simulation-based topics over other elements of the title normally covered by the media.

The two motorsports equipment companies, KW Suspension and Yokohama racing tires, are providing Polyphony Digital some critical real-world data for GT6. That data is being used to refine the suspension and tire models of the GT6 game engine’s chassis physics algorithm, improving the way the game models suspension geometry changes during gameplay. Likewise, new and more detailed aerodynamics data has also been gathered to help remodel the aero portion of the game engine. In fact, Taku told us that after E3 the team was headed north to Willow Springs Raceway with some vehicles and data logging gear to capture even more car telemetry data.

While waiting for one of his turns at the GT6 cockpit sleds, Chunx noticed the tire temperature and wear graphic overlay for GT6 would heat up when cars were sliding through hard corners, but cool off to normal in only a few seconds. It was reminiscent of how critical injuries in games like Call of Duty recover in only a few seconds − certainly not realistic from a simulation perspective. Taku addressed that, saying that tire wear in GT6′s “Hard Core” mode will allow the player to adjust wear rates and how they respond to abuse.

GT6 has a "Hard Core" mode? Color me intrigued.

Great article, those guys really know what they're talking about. Still, a couple of the things mentioned in it disappoint me a fair bit, specially this one:

We asked about Multi-Class racing, and were told that while there will be multi-class racing in GT6, there won’t be a way for the game itself to conduct multi-class race scoring (i.e. class winners).

So, in essence, we'll have the same crappy races that aren't "multi-class" as much as they're unfair and pointless groups of cars that have nothing in common. How do they expect to give us a proper SuperGT race if only SuperGT500 cars compete? Give us SuperGT300 that'll definitely lose? 👎👎👎 Honestly PD, is it SOOOOO hard to do?

 

[fabio93bg]

👍 hard core mode. this is what a lot of people want (sim racers), if this is true (assuming Taku knew what he said) it' s really a good news. it would be fantastic to have pro physics and hard core sim settings in this mode. let' s hope guys!!!
