Does this happen in real life?

Here in GT4 whern you do a tight turn the cars slows down a lot. is this something that happens in real life cars? or only something in GT4?

In cars, bikes, kinderwagons, people, dogs, planets and everything that moves.

Everything that changes its movements abruptly loses energy on that decomposed vector. Couldn't be different with the real driving simulator.

Read something about inertia. Try Wikipedia.

ok that was not very understandable but ill try wikipedia

This is caused by the "in-game" TCS. The computer is taking control and does not want you to spin out. It also depends if you have a car that tends to understreer a lot. EG;a FWD or a 4WD:tup:

Hehe

Our probably Montoya-Fan ImprezaAddict hasn't mentioned TCS or any other modifications.

I just went in the radix too early.

Any car in the game and in real life will slow down when it turns thanks to the laws of physics, how much it slows down depends on a number of factors including weight, suspension, tyre compound, tyre dimensions ect. In the game one of the biggest causes it because theres several driver aids that are switched on for every car you buy as default, you can turn these off by going into the car settings, the ASM has a bigger effect on cornering speed, or rather, loss of cornering speed than the TCS. TCS by the way is needed by even the best drivers on some of the more powerful cars when attempting to run a hot laps or to preserve tyre wear in longer races, TCS isn't something you should think you should never use, ASM on the other hand does more to hinder your performance than to increase it.

This question is suffering from a lack of specifics...define "tight turn," and define "slowing down," or just describe more completely what it is that's happening, and maybe we'll get somewhere...

Judging from the question as-is, I would bet on ASM, though...

From the original message I believe he's referring to a very very pronounced effect of the stability controls, particularly in the license tests where you cannot turn these systems off. For instance in the MINI One at Tsukuba, anything more than a few degrees of steering input is equivalent to about 60% braking.

I'm not talking about loss of momentum, because I'm well versed in driving low-powered cars. It's literally a refusal of the car to rev with any significant steering lock in.

He kinda sucks. I dont like it

oh and TVR, thnaks. that was way more understandable then what Dimitrov said

 

[sar593]

The only aids I have on are the ones of the understreer in the FF and AWD cars, the rest is off.

there always will be energy loss for every change of direction
just graph it as a function and you'll see

 

[MidnightRiot]

When you start driving, you'll see the car slow down when you let off the gas.

Wow. Did this add much to the discussion at hand? Please refrain from making pointless posts. A little levity is fine, but if you're not posting constructively as well, please consider not making the post.

 

[Uncle Harry]

When driving a real car, when you turn the wheel to negotiate a corner the car will slow down with the throttle at the same opening. To maintain or increase speed around the corner you will have to push down on the throttle.
I hope this answers your question.
In game the effect can be made worse if driving aids are on.

 

[Dimitrov]

Or, think like this.

Shorten the radius by lowering speed.
Enlarge radius by raising speed.

I accidentally left the aids switched on when driving a Fiat Barchetta around Monaco - as soon as you turn the wheel with no throttle the tachometer needle takes a nosedive; and it will not gain revs with throttle. As for real life, yes it happens - you need energy to make the car change direction - that has to come from somewhere, typically from the kinetic energy the car has. Its actually a lot more complex, but yea, can't beat the laws of physics.

If you think it's bad on stock cars, you ought to try it on a fully modified front-driver... the engine shuts down completely every time you turn the wheel a few degrees.

And that's traction control... with stability control, it's even worse.

*Cough* VW Lupo Cup Car. As in the one that's the subject of this weeks Weekly Race Series. Going around the hairpin on Citta Di Aria, everything dies and you have to coast around hoping that you won't have to give gas, because if you do, you not only slow down, but also get tons of oversteer.

 

[clanks]

Simply, before you click on to the steering wheel icon to go race, instead click on the tool box (settings) then go to 'driving Aids' and turn everything to 0, that will fix your slow turning prob. Oh, the first production car to have TCS was in 1986 so if your driving anything '86 or earlier turn it off if you like to drive it like a real sim.

Hey.....you're from ClubRSX


In terms of aids, I notice they really cause the car to come to a crawl. Right now i'm trying to gold the B test at Tsukuba with the mini (as mentioned on page 1) and I'm having tons of trouble with it because of it, they best I can come is within 1 second of gold.

 

[AdamW]

crazy: drive it like the demo run, especially on the last corner - brake more than you usually would (in a faster car, or one without aids) before you go in, so you can take the whole corner smoothly without the tcs kicking in too much, and accelerate out of it...before i watched the demo for that run i always went into the corner much faster, but then you wind up dumping a lot of speed in the middle because of the tcs and you can't come out fast. took a half a second or so off my lap times, that did.

 

[ImprezaAddict]

Cool, so all doubts of mine are solved

 

[MasterGT]

Here in GT4 whern you do a tight turn the cars slows down a lot. is this something that happens in real life cars? or only something in GT4?

When I first identified this problem doing one of the Licence tests (full lap at Suzuka, A10 - I think), I dubbed it the "steering slowdown effect" because I found it happened with nearly every car in the game. It didn't matter if it had driving aids on or not and it didn't matter what drive-type the car had. Some cars were much worse at doing this than others, though.

Sometimes we just have to shake our heads, but maybe PD put this in to simulate something. I can't imagine what, though, because, as mentioned above, it can happen with very little steering turn.

In the game, we just have to remember to keep the wheels as straight as possible with the cars that exhibit this effect the most.

Cheers,

MasterGT

Like people said on the last page, it happens in GT4 because it happens in real life. Imagine you were driving 100mph, with jusft enough accelerator to keep exactly at 100mph. If you started turning, with the same amount of accelerator, you'd start slowing down. So while turning you'll always either be slowing down, or accelerating slower than you could in a straight line. Can't dodge the laws of physics.

 

[KiwiBoy]

The TCS and ASM in this game is really stupid. In real life, some systems can actually improve your lap time and helps you to achieve a faster 0-100km time. Ex: Mercedes(ESP), Bmw(DSC3)...
