The Lack of engine breaking

Why does GT5 not have engine breaking in it?

It does.

 

[Talon]

Edit: ^ That.


You expect any of us to know?


Edit 2: \/ That too.

 

[CoolColJ]

It does, but it's pretty weak and mostly in first gear. If it was stronger then you would have lift off oversteer (once you got rid of the stability help from the ABS)

lol! you made my day, excellent response 👍

Well, there's mechanical damage but I haven't yet seen it on my way through A-Spec or B-Spec. I know I've seen the option for it when setting up a race in Arcade mode, though. I assume this would include your engine breaking.

I'm not sure about engine braking, though.

By first-hand experience and seeing feedback threads around here my impression is that GT5 needs many physics improvements to increase realism.
I wonder if the guys at PD are aware of this or they're happy with the game as it is, as they are with sounds. Maybe they're misled by subjective bias.

There is engine braking that is in this game. If there was no engine braking you would not slow down when you let off the gas. You can see this if you use a manual transmission. While the braking might not be as real as it could be. It still has a bit of realism that is inescapable.

Thank you for an intelligent answer but try this go about a 100 mph let the rpm drop down then down shift the rpm will raise but the car still stay at around the same speed I love to engine break if they put it in the game you would see the lap time go down significantly

Engine braking is in the game, it's just that it's generally weak as CoolColJ mentioned. I have never encountered a case where the car does not lose speed at all by downshifting (even without engine braking, there would be tire and aerodynamic forces, at the very least, slowing the car down).

Engine braking depends much on the engine effective compression ratio, engine inertia, internal/mechanical losses, ECU fuel injection strategy, etc. I don't think that PD took into account all these variables; probably in some cases (some Premium cars?) they fudged some values to obtain more or less realistic results, but I guess that most of the time they use some kind of poorly calculated value instead.

 

[Samus]

He's right, there is no engine breaking. There is engine braking though.

 

[r2nyGT5]

I'm confused... is this about breaking in Engines or Engine Brakes?

You are missing some peoples sense of humor.

I find this all hilarious.

Maybe because you don't know the difference between a brake (what your car has) and a break (what you do at work) ?

True, to accurately calculate engine braking you need to know a lot of specific variables about the car. However, you can generally estimate the level of engine braking as an inverse of the torque/horsepower. There is indeed a small amount of engine braking in GT5, but it's minimal and not at all close to the level you'd get in real life from a large, high-compression engine. I was actually messing around earlier today and paid some attention to the coast-down behavior of cars in GT5 and was not impressed, it seems to be fairly constant rather than being heavily related to the rpm, as well as the effect not being nearly as strong as it should be. It almost seems as if the cars are running through a torque converter instead of a manual transmission/clutch.

Wow I used the wrong word the world is going to explode I know every single one of you are all perfect and never do anything wrong

you asked about something entirely different than what you wanted to know about.
If you don't understand what you want to know, don't blame us.
Or, are we to interpret every post and change it to what we think the OP meant?
Wow.. can't believe you had the nerve to post a bitch about it.

 

[Bigbazz]

The game does have engine braking, are you expecting a road car to have the same effects as a race car or something? The physics in GT5 are very good, not perfect. I can drive iRacing (considered to be the most accurate sim by many) and then jump straight into GT5 and still feel very comfortable and at home. If the engine braking effects seem less extreme it is partly due to the game having "Auto-Blip" which basicly immitates the effects of "double de-clutching" or "heel/toe" as some people call it.

Not really sure what the issue is here, other than misinformation or someone trying to find faults with the game for the sake of arguement.

I read his post and sort of knew what he was talking about, then I read
Iceman PJN's comment:

threw me out in a loop

Well, its not a big deal, but your mistake created confusion. Braking and breaking could both be valid words for your question, but they ask 2 very different things.

 

[1Fast335i]

Yeah, I was just giving him a hard time- no harm meant. Sorry.
It does seem like no one knows the difference between the words break and brake though.. just fyi...
LOL sorry if I sounded to harsh. was messing around.

Wow! Really? How about aerodynamic drag (Fdrag=rho*Cd*A*v^2/2) and rolling resistance (Froll=mass*g*friction_coefficient)? I'd say those are a couple big contributors in slowing down with the throttle off...

 

[machschnel]

There have been a few times when I have experienced what felt like compression lock-up, although, what more likely happened is a brake lock-up. It is very hard to tell the difference as I was under heavy braking and down shifting at the same time, usually trail-braking as well.

 

[1Fast335i]

I might have forgot some but I remember it as to ForceDrag = 1/2 Mass*Velocity^2 *(CoefDrag)*area
If you want to get technical.

Nope. rho=air density. Mass makes it a force*volume unit (WTF???).

In SI units: rho=kg/m^3, v=m/s, Cd=no units, A=m^2, so F=kg*m/s^2=N!

all cars Race or Road have engine braking (auto equipped cars very little) but the game replicates it very poorly. Is the "auto blip " you speak of whilst using a ds3 or a proper wheel? I use g25 and there is no "auto blip" unless i instigate it.

Sometimes when racing fast cars (ZR1 etc) the game wont let you heel -toe back to 2nd (doesnt like being rushed????) like the shifter is broken which sucks big time.

As far as "finding faults for the sake of an argument" goes, I think we at GTP need to discuss GT5 physics more comprehensively, as i find this is what makes or breaks a car sim.......not whether or not the shadows are jaggerdy or the paint options are rediculous!

I played Live For Speed (with ****** generic cars and no RL tracks:tdown against friends online religiously time after time just because it felt real.......but i find GT5's lack of low speed physics, collision physics and unrealistic mechanics (eg engine braking, shifting feel, clutch actuation etc) below par.

Sometimes you want to just jump back in bed with that mediocre looking sex vixen that makes your balls tingle ....than have sex with the dead root cold fish that has double D's, a perfect ass and a pretty face!

 

[pcreque]

What the engine braking and other issues such as terrible under steer and tire compounds that not even drive-able boils down to is bad physics. I don't understand why they could adapt and improve the driving physics from GT4. There is a lot of things that don't work, or hardly work in this game. I.E. trans gear ratio adjustment, or lack of it.

I like the GT4 format for tuning better and the functionality of having pre-sets. I would have like to see 300 premium cars and better physics, I'd give up go karts and N.A.S.C.A.R to get back to a driving simulator, where you can win prize cars and money more than once, and sell cars to gain cash.

Perfect example of engine braking. Camaro SS RM, red line in second then shift to first without hitting breaks and see how long the car keeps it's speed.

thanks for letting me vent....

Better late than never- your right. Sorry, been quite awhile since school. I'm an Electrical Engineer so I don't use the mechanical stuff I studied at all. Kind of forget the formulas!

You can edit the thread title.
And engine braking is in the game, I'm not even sure it's weak. Just as cars seem slower in the game than real life, (200MPH isn't scary as hell) engine braking seems to take longer than IRL. 👍

Right, which is what would happen in a real car if you properly rev-matched downshifts instead of putting undue stress on the clutch to coast down a little quicker.
