I find on the straightaways that drafting is very effective in GT5P, however when I watch professional racing on road circuits there is no where near the advantage that is gained in the game. ex. Suzuka 1000km race, F1 races etc...

I realize that the higher the speed and down force levels the more effective drafting is, but it just seems exaggerated in GT5P.

I have also driven various cars on numerous circuits (in real life), albeit not in super competitive racing and I don't find the affect in real life correlates with GT5P.



Mods, if you think this discussion should belong in this thread I apologize, but it concentrated on bump drafting, which I don't intend to discuss here.
 
I agree that it is exagerated. It shouldn't really be, but it's the same argument as with the rubber band - it offers closer races.

I guess PD chose excitement over reality in these 2 cases.
 
I don't mind the exaggerated slip-streaming, it provides close races while not being rediculous with RBE. I think it's more pronounced than GT4 though, which is a little disappointing.
 
Drafting is spot on imo.
In fact the only thing in GT5P actually reminding me of RL, also i think the dirty air effect is very good! Annoying at times, but feels exactly like it should 👍
 
Seem exaggerated compared to my experience in real life and my observations of series like the BTCC WTCC, F1, A1GP etc
 
Definitely over exaggerated. If you watch F1, where the cars run huge amounts of downforce, the draught they get when running behind a car only just allows them to pass a competitor when running down a lengthy straight. If it only just gives them an advantage, getting a draught off a car thats half the main straight in front of you @ Suzuka isn't realistic.
 
Definately exaggerated, in the past its caught me out sometimes by hitting the driver infront of me by accident. So unrealistic PD have got a big list of problems to sort out, but I'm staying positive for the future of Gran Turismo 👍

You're not serious right?

I voted YES..
 
Drafting in F1 only works when the cars are very close to each other. Next year the aero rules are changing to try to clean the air up out of the back of the cars to increase overtaking. F1 has become a real procession on race day as a result of dirty air but I still watch it.

In GT5P I’m still unsure if drafting is exaggerated or a little bit off or just fine. If you look in your rear view mirror you’ll see the trailing car is way behind but suddenly he comes flying up on you. Now had you looked behind using the rear view button you’d see he was actually much closer than the mirror implied. Odd seeing as when you get into a real car there tends to be a sticker on the mirror saying “objects may appear closer than they are”. Certainly not in GT land where objects are a hell of a lot closer then they appear to be.

Err...as others have touched on in this thread, F1 cars produce so much downforce that the air behind them is turbulent, rendering drafting rather useless.

Perhaps you misunderstood my comment. In a straight line drafting is most effective at high speeds and high down force levels because there is more turbulent air. The turbulent air created by the lead car makes a bigger "hole" in the air providing less air for the second car to move "out of the way". What I actually think happens; is that the velocity of the air in the desired direction is increased (by the lead car in a small envelope). Therefore the speed difference between the "drafting" vehicle and the air immediately in front of it is reduced providing less wind resistance (or lower down force levels).

Finally, in a corner, less down force is not usually a good thing making it very hard to closely follow the lead car as in F1. But in the right situation drafting can be very effective in F1, take the last two races for example, Spa Francorchamps and Monza have very long straights were drafting is common and a useful means of overtaking.
 
yes its over pronounced and i don't like it. it makes it too easy for people to catch you, especially when racing the F1 car.
 
My personal opinion is that PD does this to keep the racing somewhat closer as to give everybody a chance. But it really isn't fair. If you have ever raced any of the Daytona oval races in GTP5, it is really absurd there,you can not,in real life, draft from 1/4th of the way down the back stretch and catch the leader by turns 3 & 4.
 
It's a real problem on fuji too...especially when some person holds the lead for a lap or more and suddenly is about to get passed by the exact same car he's driving because that car is drafting him...the finish line is approaching so right when you try and pass BAM! they side swipe you and take the win.

It's really stupid.
 
No the drafting isn't over pronounced it is 100% perfect, like the rest of the game is, although there are stuff needed to make the game even more fun but overall for reality I give it a 10

In reality, even in 200 km/h I feel drafting in real car really good and I can actually hear the wind to quiet down, but only tightly behind the car and certainly not being tens of meters away.
 
it's a bit over done, but still like it. like said in the F1, someone from Mclaren told that they're car suffers and loose downforce etc when driving 2sec behind a other car... in slipstream it is some better but really difficult to conrtol the car(kovalainen).

as for dtm.wtcc fia GT etc etc etc, it is better done. they need to tweak it some more but it is a nice future.
 
Yeah I think GT5P over did it a bit, Even driving on normal HIGH way you don't get as much draft as in GT5p.
But guys, We need to get more detail if they did it correctly or not, record some MPH and we need two of the same cars in game and draft them. Compare 80mph then 100 and then 150mph. Going on a highway 60-70 MPH can be much different when going 150-160mph in game. Doggyollie, you say you raced in real life, how fast were you going the most when drafting? We might think GT5P over did it but we might be going 150mph on a straight and think it's over did it when in real life we never did it... but who knows, better to collect data and come with conclusions...
 
I was playing yesterday, online, and this subject came up. The most important thing i noticed to be wrong, is how the drafting effect is done. In a nutshell, drafting creates a zone behind a lead car with less air friction, allowing the pursuit car to consume less gas/energy to maintain the same power/speed. From this effect, it is easier for the pursuit car to gain "extra" power to overtake the lead car.

In GT5p (and other Gts actually), when getting to a corner, if both the lead car and pursuit car slam the brakes at the same time, the pursuit car is "sucked" straight in, almost always resulting in a visit to the kitty litter.

Now i'm no expert on the subject, but after reading most of what i could find on wikis, it seems that this behavior is completely wrong. While the pursuit car gains the advantage of less air friction, it also gains in downforce, grounding it almost as much as the lead car. Braking, if felt lighter on the pursuit car, shouldn't feel like it is being sucked in by the lead car at all. As the lead car reduces speed, the air friction changes (lowers in density/reistance) and the aerodynamic effect is subsequently lowered as well, creating less of an effect in downforce and friction reduction for the pursuit car.

My observation in GT5p right now is that, the pursuit car is actually "dragged" closer to the front car with no effort. I first noticed this on Suzuka during the long straighaway (end of track), where i had a car in front and didn't want to overtake... i let go of the gas and my car was still "accelerating" towards the car in front. This shouldn't be possible both because of air friction, but also the sheer mass of the car. I actually had to brake to lower my speed.

Any takes on this?

Definitely!

Although its good that its there the effect should make less of a difference and you should have to get closer to slip stream.
 
When slipstream start over a second behind, then its clear that something is wrong! I understand that PD did this to keep racing closer just like RBE, but it feels wrong..

Merry christmas!!
 
It is over exageratted. I have done wind tunnel testing at Uni and a car at high speed has to be directly behind another to get the slipstream effect. I mean with in 5 meters. Although it all depends on the cars aeros in front. If its got a low drag coefficient like 0.35 or lower it pretty much has little effect of slipstream as the air is just flowing to smoothly over the car in front and the air vaccum behind it is relatively undistrubed. But with high drag coefficient ie race cars with pure downforce the air behind is all diffused meaning the vaccum or drag is higher sucking the car back or down so the car following uses this SLIPSTREAM to its advantage using the disturbed air.

I think i explained it the best i can.
