Here's something that's always annoyed me for as long as I've been playing GT games. Why do cars slow down once they reach maximum speed? They don't do it in real life...

Why didn't they just keep it the same as other games do, and just keep the car screaming at its maximum RPM? Sure, the poor car probably wouldn't like it, but it makes the whole experience of maxing the car that little bit more frightening and exciting, like it should be.

It actually makes me try and avoid maxing my car, because having it constantly slow down and speed up over and over again really takes away from the realism for me. Why does it do it????
 
I dont know why they do it, but what I do is see what the max speed is before it slows down and I ease up of the throttle a bit to keep it at that speed.
 
Idk, maybe it's to not overheat the engine in real life. Not sure.
 
I'm not sure but I think it might be the engine being restricted by the rev limiter, which causes the effect. I might be wrong though.
 
Are you talking about when you hit the rev limiter in the top gear and lose about 5 or 6mph? I have never experienced this, my cars top out about 300rpm away from the rev limiter and they hold their speed on smooth parts of the tracks.

Yes, the rev limiter is what causes this. It drops the revs a certian ammount once reaching the limit.
 
And your transmission settings are not suited for a high-speed track.
 
It is very wierd how they do it and not like any sort of rev-limiter I've ever seen watching racing, how it's so long and sluggish to cycle. It works ok in the low gears but in 5th or 6th it's really odd. It's especially comical in slow cars maxing out at 75 mph and then spending 5 seconds slowing down to 68 with nothing you can do to break it up.

But that's how they've always done it and the GT series is perfect or so I'm told and so why would they ever change it?

BTW if you play with the throttle to prevent it happening you can improve your laptimes and often reach a higher speed than where the cutoff is. This is particularly pronounced when in the(also uber-realistic) Superslipstream.
 
if you hit the rev... just half the throttle and you will hold the speed.... (best exampel: Top gear test track with samba bus and kübelwagen)

but this one is old...

That is what I do. If you just keep your foot to the floor it will slow down and speed up, but if you back off slightly you can keep the car at the max speed.
 
********, its called a rev limiter. Floor your newer post 2005 car down a rural (I mean RURAL) highway up to top speed. If your car is newer it will have a rev limiter. Mine maxes out at 126 mph then hits the rev limiter and stalls real quick down to 115.

Now if you live in a populated area dont do this, but if you live near the Tundra like me (canada, boundry waters, etc) then its do-able.

My 2003 Ford Focus did that when reaching 170km/h (on a closed track), it would decelerate to 160 then re-accelerate to the cut off

Did they just invent rev limiters in 2005?


I didn't think so. The majority of petrol cars have had them for ages, they are uncommon on diesels. I would be amazed if you car hit the rev limiter in top gear even if it is a fairly pathetic (indicated) 126mph.
 
Those are speed governors, not rev limiters. A rev limiter only cares about engine revs to save the engine, it will work the same in any gear, not come on only once you reach a set speed. I've always assumed those street-car devices what they are basing the GT one on, but it would be removed in a car that was tuned for racing, not constantly re-set to the max rpm in high gear. I've seen race cars hit the limiter in high gear or the one below it several times, and it's just as quick an on-off as it is on a pit-lane limiter(well technically probably slower, but something like a .25 second cycle instead of .1).
 
It's a rev limiter, NOT a speed governor.

If it was a speed governor, it wouldn't do that redlined in first gear.

Which is why it's wrong. It acts like a rev-limiter in first(since it's fast and tough to tell the difference in a fast car, but you can see the wierdness in a slow car), and a speed governor in sixth.

Since I'm not in the habit of redlining my car in low gears(well, any gear) it could very well be that it has something similar, and the game is just based on the street version of a rev limiter instead of a race-car version. That makes the most sense for explaining the way the game works, but it's still wrong.
 
I can see what the OP is talking about:



Now try that in GT5. You'll notice that the rev limiter somehow has to drop a certain number of revs before allowing the throttle again, meaning each of those "bangs" on the revs become slower with each gear.

How many time did he hit the rev limiter before changing gear? That was an awful bit of shifting
 
It was faster to not shift for .5 to 1 sec than making the shift and not even getting to accelerate before slowing and downshifting. Also on some of the corners, not upshifting allowed him to go through the corner without downshifting. I loved how the shifter moved around like the car on the track, in hard corners it would move with the cars weight, the whole gearbox must of been shifting around a bit.

I'm talking about the times when he hit the limiter on a straight before upshifting. He did it quite a few times.
 
That is how a rev limiter works. It cuts the throttle just a little bit before opening for it again. In modern cars though that is usually very rapid and is known as the rev limiter bounce. I guess in older cars the rev limiter was more crude and it took longer time for the throttle to open up again. Maybe PD just isn't in touch with the time?
It would be more realistic if it just kept bouncing rapidly against the redline, but generally i don't like the sound that makes anyway, and it is quicker to have as near to 1 RPM left on the clock in top gear down the main straight with a fair bit of tow then it is to let it bounce. Because each bounce is basically just a waste of engine power.
 
I see, didn't realize. I thought maybe the tires were just spinning on the straights going over some of the bumps. However I have no idea why he would be not upshifting on a straight. It is annoying in GT, but we all must deal with it like the rest of GTs issues, we can't change it and allthough PD can they don't seem to care much about small issues like these.

Watch your language. This is a warning.
