Lately, I've noticed a problem when the front wheels are turned from just bit off the centre-point upto steering-lock, especially under power when exiting hairpin turns. When the wheels were cranked, problably close to the extreme, the car was noticably and unnaturally slowed by the fact that the wheels were not straight. Hmmm...

Someone suggested that TCS may be kicking in and doing it, so I did a bit of experimenting and my conclusion, so far, is that it doesn't matter which car (FR, FR, MR), how much horse power it has, which tires you use, or if TCS is used or not, steering-slowdown is always there, in varying amounts. With the Honda Beat, there is so much steering-slowdown that it almost stopped the car! With the Cien, I exposed it even on a straight, just by going from lock to lock!

The only way I have found to eliminate steering-slowdown is by keeping the front wheels straight.

Cheers,
 
This happens most extensively in the license tests with the FF cars that have way too much ASM and TCS. If this is happening to you in gt mode, turn off the ASM and TCS and it should help 👍.
 
it's perfectly normal, and realistic, the front wheels are just grinding into the ground instead of turning the car because they are at such an extreme angle compared to what they should be at. in real life and in the game, when racing, you should hardly have to turn the wheels at all.
 
I did further tests and found that every car I tested, not matter what type (FR, MR, FF), no matter which tires were used, no matter how much power it had, no matter at what speed I tested, no matter which driver aids were/were not used, all cars tested showed some degree of steering-slowdown.

It is clearly unnatural.

I was able to slow the Honda Beat to a crawl (to less than 20mph!), just by turning the front wheels. I was able to slow a car on a straight stretch of road just by turning the steering wheel a bit off centre. If I quickly rocked the steering wheel from lock to lock, the cars gained speed, probably because there was a portion of time when the wheels were pointed straight ahead.

It does not have to be very much, either. Just a few degrees off centre is enough to notice this effect, on some cars. The only way I have found it doesn't happen is by having the front wheels turned straight.

Beware!

Its natural, cause in real life a car also decreases speed when turning, and if you keep turning you will lose all speed with cars like an civic and that shi.tty cars

Isn't that kind of natural though? D:
Like, if you'd do that to a real car, do you Really think it'd keep the same speed? The wheels would turn faar too much and you'd be driving with them just sliding, horizontal. This is what happens for me if I do maximum turning (DFP (which means that ofcourse, I have absolutely No time whatsoever to do it lock-to-lock quickly)), and it makes sense to me. :odd:
 
And as standard these cars are on sports tyres which appear close to semi slicks.
Is the effect less pronounced with normal tyres?
 
One thing i notice is that how much throttle you give it depends on the steering angle.

To show this: get a car you can control at low speeds, and bring it to a stop on a wide straight (Sarthe?). In the exterior view, turn the car to full-lock (anydirection) and gently apply a few revs, so you can see the side of the car as it turns in a small circle - no more than about 20mph. As the car is rolling, suddenly put on full throttle whilst still holding full-lock. You'll see the tyres actually straighten up - how unreal? In real life, the wheels stay at the same angle regardless, the only problem is how much grip you have determines how much you can steer.... so why is this happening?? It applies to all cars, and was evident in GT3 as well. The steering physics seem a little strange :crazy:
 
Yea, like he has driven and done that on the Le mans track.
You forgot by the way there are bumps wich affect the results, and normally the car will jump out of full lock, because the driver gently loses 100% grip of the wheel. so it's realistic
 
But why are all you guys trying to find bugs ect? it only ruins the game for you and people who read this, because they are gonna pay attention to it, even if they wanna forget it. The game is finished, nothing that you can do, leave it. PD won't read this forums, i can tell you that for 99% sure.
 
I can tell you 99.9% sure that PD do read these forums, unless they don't listen to their fanbase at all? This is probably the biggest GT community, with the most people, and therefore the best reflection of worldwide opinion.

I'm glad somebody is paying attention.
Thank you.

We could have the gas pedal floored, but when the steering wheel is turned, we only get to use a portition of the power that we would expect to have available. As soon as the front wheels straighten out, we get all of the power back.

There is a marked difference between GT3 and GT4, though, and it does affect our speed more. It only takes a few degrees to become noticable.

I didn't make this my life's main quest, to find GT4 bugs.
It hit me in the face! I didn't ask for it to happen.

It also does not ruin the game. All I want to know is what is happening, what causes the effects and how to best deal with them. The more heads that get banged together, to come up with a good solution, the better.

99% sure, eh? Here is that 1% you needed. This is from yesterday's GT4 chat, with at least a couple of SCEA executives, including the US Producer and the Product manager in charge of GT.

"manolo32: This is Stephanie Y., Product Manager for the Gran Turismo franchise - I just wanted to let you know that the GT dev team regularly reads the Message Boards for feedback and ideas. We encourage you to continue posting! Thanks for your time"

"Taku Imasaki: To MasterGT: ... We'll keep your feedback in mind. I will get on the boards soon and get your feedback on what American cars you want to see."

"Taku Imasaki: To 3rdgenracerX: ... But we will continue to poll your interests to determine what you are looking for. "

"manolo32: This is Stephanie Y., the Product Manager for the Gran Turismo franchise. ... Please continue to post your feedback on the message boards as we check regularly."

👍
