GT4 Acceleration Times vs. Real Acceleration Times

[the Interceptor]

55" HDTV: $1,799.99

You bought this display only for GT4?

I do understand and I don't complain that Gran Turismo is not that accurate in some figures, but how do they archieve those "within 1% of the real life laptime"-laptimes then?

 

[3rdgenracerX]

Dont forget the memory card!: $24.99
Oh yes, it's 1080i now, 55" HDTV: $1,799.99
Component Cables: $49.99

Total: $2074.95

I hope it does have realistic accel times cause that is what I actually paid. (+8.517% tax)

To play GT4 you don't have to have the 1800.00 HDTV, a regualr tv will work just fine. A 200.00 tv vs a 2 grand hdtv = almost the same GT4 experaince's. Same applies to buying the Logitech DFP 100.00ish dollars, you dont have to have it to play GT4 but it does add a better experiance to playing GT4.

Its not like you'd have to upgrade your PS2 to play GT4 at its best possible gaming and graphical quality, say more memory, graphics card, sound card...ect that could total above 2 grand as well. Especially if you had to send it to Sony to upgrade it since they are the only ones with the upgrades you need on the market. THAT would make it a case of GT4 being that realistic if we had to upgrade our ps2's just to play it.
But as far as a luxury item's goes to enhance your gaming experiance in GT4, then it doesnt have to be 100% perfect for 200 bux. Tv price excluded since everyone who's going to buy a gaming console has a tv prior to that purchase.

Honestly, who knows why PD cannot program each car to have the right gearing to produce accurate quarter mile and top speeds as their real-life counterparts? I'd take $15/hour from PD to sit down and plug in each car's true-to-life gear ratios and final drive and assure that they ET and Trap their most accurate average times and MPH/KPH. It certainly is disappointing that something SO SIMPLE was axed on PD's priority list to make this more of a realistic racing game.

Bottom line, i'm still going to enjoy GT4 as a true quality racing game. I will not, however, consider it to be the REAL DRIVING SIMULATOR until they spend a few hours out of the years of development to give the cars real-life gearing, engine sounds, powerbands, etc. etc.

I know guys. But I mean, as soon as I heard GT4 supported 1080i; I bought the TV within a week. I've been waiting for it[GT4] for so long, it would be hard to own the game and not be able to see it how it should be seen, in hi-def.

 

[Taneras]

GTR, GPL, many of the F1 games, theres a few but they're all on the PC. At least until Enthusia and Forza come out.

Do any of those games have the modifications like GT4? Like superchargers/turbo chargers, intercoolers, exhaust/intake, chips, transmissions, flywheels, etc., etc., etc...? What about the setup changes like suspension and gear ratios?

Its very easy to get near perfect 0-60, 1/4 mile, skid pad, etc. when your dealing with a car that can barely be changed. But when you have all the options like in GT4 its kinda hard to get a car perfect when there are thousands of different ways to set it up.

 

[YZF]

I don't know where were you looking, but gt4 accel and top speed are very accurate.1/4mile as well.

keep in mind that rx8 is typeS version (japanese, 250hp) and at the end of Nurburging you go down hill! Watch more onboard videos from BestMotoring (like New NSX TypeR) and you will see that top speed in that exact place is the same.

Also keep in mind that some cars show more on their onboard speedos than they are going, and GT4 might do the same (speedo shows little bit more).

Still i would like to say that GT3 definitely had much higher top seed and some sort of lower air resistance BUT it is fixted with GT4 (definitely you reach top speed much sooner and much more realistic).

Noted that the Japanese version has 13 extra HP but that would not affect the top speed much. I was running the Ring straight in the opposite direction so I was ending on a slight uphill. I recall very few correct top speeds in GT3. The Z06 was correct but it was gear limited and drag was not a factor.

 

[YZF]

Maybe your "source" isn't reliable? I checked mine and everything is OK....

And please,use final GT4 version and not demo....lets say top speed test around driving park.

 

[T5-R]

Hope your right YZF

/Imagines the TVR Speed 2 struggling to do 140mph whilst the Fiat Panda eventually overtakes it after 30 laps when it finally reaches 145mph...

 

[cjrciadt]

/Imagines the TVR Speed 2 struggling to do 140mph whilst the Fiat Panda eventually overtakes it after 30 laps when it finally reaches 145mph...

Hope thats not true. Fully tuned the Speed 12 in GT3 hit the wall aero wise at 255mph without the draft 280mph with a draft. Its not so sleek front end and very wise stance made even this light vehicle hard to push thru the wind which is realistic more so that other cars in GT3

 

[YZF]

Now i checked Integra (old) accel. 0-100km/h does in about ~8.2 sec. BUT acceleration is OK, top speed also OK (244km/h) but it looses lots of time when making shifts (!) and at the launch (tyre spin). So engine response and acceleration is ok, only gear changes take time...maybe this car is hard to drive (change gears)?

Or maybe i should buy racing gearbox

Also wathced recently BestMotoring 911 GT3 test on Fuji, Kurosawa did 271km/h (onboard cam) at the back straight, i took ruf (gt3) , top speed there - 272km/h... you can't be more accurate than this.

Also checked Audi RS6 top speed, here in game it does 301km/h (MTM site says 295km/h oficial top speed and i believe you will see speedo showing 300, maybe i already saw it somewhere on video).

So conclusion would be that top speed is accurate and it shows not "real oficial top speed" but the one that is shown in car when you drive with it.Speedometer readings are always little bit higher in all cars, and thats what PD made for GT4. REAL stuff.

I'm pleased

 

[Superhero Wally]

I have you're "driving simulator" right here, and it's called the Hexatech, oh and it'll only cost you $300,000. There's an article in the Jan issue of CandD pg. 42. It's made by a company based in the netherlands called FCS Com, a subsidiary of FCS Control Systems.

So I have no prblem paying $50 dollars for GT4(when it's released) and the simulation i get from it.

I wonder what kind of software/hardware PD used to create its physics...probably for the 3.000.000 $

They all allow you to setup your car to your hearts conent, bt they don't offer upgrades, however that was not the question and is an attemp at rationalising. While I agree with you and hold nothing against PD for not being perfect, your missing the point I was making to that other guy.

An RS6 does 185mph? bloody hell... From what you've said it sounds like they've improved it for GT4, yay. Although I'll still try to find a way to overtake a Speed 12 in a Panda

 

[syclone538]

One thing I was really miffed at in GT3 was the top speeds of some higher end cars, it wasn't small differences either, one of the more notable ones was the TVR Speed 12 which struggled to hit 140-150Mph in GT3, now even though the car has never been tested for top speed it's rated at 240Mph+ and common sense tells you it's a 220Mph+ car even if you don't see it hitting 240Mph.

Can you test this again?
I tried top speed of the TVR cars in GT3 and got
Griffith 500 182.5 limited by power
Speed 6 184.8 limited by power
Speed 12 218.8 limited by rev limiter

 

[Nissan G10]

Two of the worst cars in GT3 were the original Mini which had an 18 second 0-60 in the game and around 13 seconds in real life. The other car was the Audi Quattro which was 13 seconds in the game and around 8 seconds in real life.

Talking of wind resistance or whatever. I took a Lotus Carlton to the straightened Le Mans curcuit and it topped out at the correct speed (around 175 Mph). I haven't checked the figures, but the acceleration does not feel that special.

one more worst car:TVR T350c in gt4
The gear ratio in the game is wrong. The top speed of T350c only reach around 250km/h at top gear red line but in the real life it should be over 280km/h.
i hope it will be fix in the PAL version.

 

[PopTarts]

Maybe one thing to consider for the difference in times are the tires. Tires can make all the difference in the world, right?

I haven't played GT4 yet, but the simulation in GT3 for the stock S2000 did not feel right with "Simulation Tires" in terms of its acceleration and handling. By this I mean that I couldn't corner or accelerate as well as my car ('03 S2000) does in real life. When I put the "Sports Tires" on, it felt a lot more like the Bridgestone S02s that came with the car.

Now, having recently changed from the S02s to the Michelin Pilot A/S tires, now I feel like the S2000 handles more like the "Simulation Tires". The S02s are designed to be for summer dry traction/racing, while the Michelins I give up some of that handling for snow/wet traction.

So maybe some of the reviewers for the Integra are using high-end tires, while you're using the "Simulation Tires" which may not have as much traction.

 

[syclone538]

After buying a racing transmission and adjusting gear ratios for awhile I got the Speed 12 to 235.6 mph. I could get alittle more if I kept trying, but not much as I’m only gaining .1 mph each time I adjust ratios now.

 

[YZF]

one more worst car:TVR T350c in gt4
The gear ratio in the game is wrong. The top speed of T350c only reach around 250km/h at top gear red line but in the real life it should be over 280km/h.
i hope it will be fix in the PAL version.

maybe its not a bug, only a close-ratio gearbox that could be ordered when buying this car from TVR?

P.S. I'm testing various cars now on Nurburgring....my times are +- 2sec from real cars....thats nice!

 

[Dave A]

Nope, TVR doesn't do that many gearbox's and when you buy a car your not given a choice. The cars just wrong in GT4.

Have you even listened to what many of the people with the game are saying????? Most of the cars acceleration and top speed wise are nearly SPOT-ON! Sure, maybe a couple of cars are not exactly like their real life counterpart. Bust MOST of the cars in the game are correct. THIS PROBLEM HAS BEEN IMPROVED OVER GT3.

 

[Dave A]

Yes I have, I've not said they arn't accurate in GT4. I was answering to YZF's post. Have you read any of my posts? If you have you'll notice my earlier comments were about GT3 not GT4. I know GT4 is not perfect but so far my onl comment on it is the one you quoted which was backing up what Nissan G10 said, which leads me to my next question, why quote me when I was backing up the other guy? Surely you don't need to vent your anger and frustration in this topic, do what eveyone else seems to do and do it in a Forza thread.

 

[WRX02Slowness]

As long as things have been improved over GT3 as far as accuracy in top speed, 0 to 60 and quartermile, i'm plenty happy.

[AMV8]

So, Evolution...still waiting to hear your opinion on the M3. How is the realism?

 

[nsx_vtec]

I dont agree with that at all.

How many games has the Gran Turismo franchise sold, something like 36 million? Do you have any idea how much money that is if each game sold for $50.00, or even $20? Let's say all 36 million copies sold for $20.00. $20 x 36 million = $720,000,000. Three quaters of a billion dollars; realistically it's over 1 billion, since most of us paid $50.00 when the game was first released.

I understand there are development/packaging/marketing costs etc. but it's a very small percentage of the final figure.

With that being said, I definitely think the game should be more realistic and true-to-life than it is. They tote it as being "THE DRIVE OF YOUR LIFE" and "THE REAL DRIVING SIMULATOR". Are they talking to you when they say that? because it's not the drive of MY life when NONE of the cars handle/accelerate/sound like their real life counterparts.

600+ cars (whatever the inflated number is now..) and half of them will never see my garage, and chances are, yours either. I say give the cars that everyone will use, REALISTIC traits, and program the others with the normal mediocre Gran Turismo handling/sound/performance.

interesting arguement but be thank full with what you got. in gt3 which was realesed for $100 dollars australian the average time spent transfering the car into the game was a couple of days. there was less tracks , less cars , less realism ,. now the engigne sounds have been recorded straight from the car the tracks have been re created with in centimeters and the lap times are with in seconds of there real life counter parts. and for gt4 the average time spent on each car was one freaking month!!!!! stop winging be thankfull that gt4 is Only $50 US and do some bloddy racing


p.s how does p.d know exactly what cars people use and dont use

 

[Greyout]

the biggest error in acceleration comes from PD's upshifting method (roll in neutral until the RPM's drop to match the next gear) not from physics problems.

on the other hand, you would thing factual on-paper car data would be the one thing PD would get right (gear ratios, tire diameter, final drive, and the resulting speed in each gear.)

 

[plfrench]

Nope, TVR doesn't do that many gearbox's and when you buy a car your not given a choice. The cars just wrong in GT4.

I'm pretty sure you could order different ratios at least with one of the recent models... Although I think even the lowest geared version would still comfortably crack 250km/h.

Paul.

 

[YZF]

This car (tvr) does 260km/h

 

[Double_R]

Thinking about it now GT3 is shat. The need for speed franchise is shat aswell infact all racing games on the ps2 are shat compared to Gran Turismo 2.
