So literally that Power-to-Weight number is basically how powerful the car is then...

Of course there are plenty of other factors (drag, handling, gear-ratios, rev-limits, torque, grip etc)

But in the most basic of terms power-to-weight is the number you're looking for.

C.

PS I'm pretty sure the weight goes down in your garage when you change it... technically (Going back to another topic) this should mean that you could probably gameshark the weight down? (He he he... Get an Aston Martin V8 which weighs 400KG?!

question: when you modify a car by 'lightening' it GT/GT2/GT3 (stage1-3) does its weight change in your garage menu? - i've been meaning to check this for ages but never get around to it.

It reduces the total weight of the car, in some cases dramatically. It is explained in "small letters" in all 3 games in the tune-options.

In first GT, adding a Racing Modification (popular "R") reduced weight even more for some models.
 
I think we all knew that... But what he meant was does the figure physically change in your garage or does it stay the same but the computer knows you have Weight reduction stage 1 2 3 on and then reduces the weight in the race?!

I'm pretty sure it changes in your garage cos I remember taking the weight off of some cars and then checking it and thinking that it did hardly anything... so there must have been a way to check it!!

Not quite - power-to-weight is more of an indicator of overall performance expectation. I say expectation because if the car isn't set-up right (bad handling/wrong gearing etc), it could still be slow (on a track) .

BHP is how powerful a car is.
 
Yeah I really meant measure of power relavtively!

it does... and yes the # changes in the garage too. You can reduce weight significantly on some cars too... and it does result in performance enhancements... i bought a stock S4 in GT3 and did a test by performing a weight reduction enhancement only then doing the 0-1000m machine test, and saw faster times after each stage when compared to stock. so it does have an effect and power-to-weight is factored in GT's physics engine.

Fibreglass = Carbonfibre doesn't it?

similar in fabrication method, but thats it.

Per the discription that is provided in-game, it is safe to assume that the weight-reduction mod in gran turismo involves composite body panels (either fiberglass, carbon fiber, or both). However, these body panels are painted to match the car.

The latest trends in aftermarket automotive styling as seen both at SEMA and on the street are leaning toward carbon fiber body panels being at least partially painted, if not completely painted - not left naked. if the stunna in you is a bit behind the times and still likes the black-hood look, then keep your fingers crossed for the ability to leave CF unpainted in the paint shop.

Yes as Cracker says the power to weight ratio is a good general indicator of straight line performance however the important things that actually dictate a cars real world performance come down to how well the power is transfered to the road........ so tyre contact patch, gearing, transmission loses, torque, suspension etc. all play an important role in how a car will perform. The laws of physics also play a big part in real world performance...... the biggest factors being inertia/weight and friction (grip, wind resistance, downforce)...... the lighter a car is the less inertia it has....... so given an example where you have two cars with the same power to weight ratio but one car is half the weight of the other, you should expect the lighter car to be quicker due to its lower inertia.
 
power to weight ratio can only tell you something about the straight line performance (and even there you still have to think about gearing, grip and drag).

of course on a tight track the lighter car with the better suspension will be quicker than the heavier car even if they have the same power to weight ratio.

so instead of increasing the power, which does not change the handling on a tight track, it is much better to decrease the weight (for example by replacing the hood) to achieve the same ratio. because then the car will handle better and accelerate faster as well.

mercedes amg cars accelerate pretty fast, but none of them will beat an m3 csl round a tight track...

Yep and here are some example track times for cars with virtually identical power to weight ratios (245-255 bhp/ton) on the Nuerburgring taken from http://www.track-challenge.com

M3 CSL = 7min 50 sec
SL55 AMG = 8min 12sec
Aston Martin Vanquish = 8min 17sec
Audi RS6 = 8min 20sec
Mitsubishi EVO VII = 8min 25sec
 
Isnt torque more important than Bhp?
 
no... you need both... high torque with high horsepower is "God"

his waterwheel example should clarify it or the Corvettes... the reason the LT1 is faster is b/c it has higher horsepower even though they have the same torque.
 
Torque is more important in heavier cars, F1 cars don't need much torque because they have little weight, so the engineers didn't waste time and resources giving them torque and they have very little respectively.
 
GTXLR
If I read it right, torque is God especially if you can gear it right.

The BHP Vs Torque arguement usually ends up in a bun fight...... anyone argueing that either is better than the other is usually talking out of their arse...... torque and BHP are linked you can't have one without the other.

On the road a car with a strong wide torque curve is easier to live with as its more flexible it can accelerate well in several gears....... however that doesn't make it better than a car with lower torque that is driven in the right gear. The Nissan 350Z has bags ot torque and pulls well across most of its rev range but its no quicker than an S2000 when the Honda is driven correctly (the S2000 has a very low torque rating for its class).

On the track torque is less important as race car drivers always try to keep the engine in the power band. F1 cars have relatively low torque but massive BHP.

Sure thing. There's actually a few confirmed as such:

S2000 LM Edition
HSR-II Concept
Impreza WRX STi
TS020
Harrier L Edition
Eclipse Sport
Atenza Sport
DualNote Concept

As for pictures, those sadly aren't available yet but I'm sure they'll surface soon!



My pleasure.

You get an F in subtlety. You get a U for the joke itself. You get a C for the delivery. You get a K so I can continue this lame post.
 
Fortunately I'd already taken out a patent on such a joke delivery system as you just implemented, as I'd intended to use it on the next n00b. Needless to say, the royalties you now owe me are substantial.

Is it not great, or is it sad?, that such a sh**tty thread turns out to be such a good discussion with a great link to a great web-site ??!!

Luggnutts is having a laugh :grumpy:

Carbonfibre is Carbonfibre and fibreglass (or glassfibre) is fibreglass - totally different.


Will Carbonfibre hoods (surely only seen in replays anyway) make GT4 a better game?

Will they make a car handle better or go faster?

No - so whats the point in having them?
Click to expand...

Yes there is, all you need is a carbon fiber hood/wing and a nos sticker adds 50hp.

Fibreglass = Carbonfibre doesn't it?

They're similar in terms of weight but carbon fibre is less prone to cracking and can handle more stress and is therefore more expensive.
 
Yeah, carbon fiber weighs a bit less and is stronger. Also, show quality carbon fiber requires a bit more work, adding to the extra cost. Non-show quality,unpainted CF costs less than what you see on most cars. ... I love my carbon fiber hood. 👍
 
IMHO , you never know if a car is fast judging only 1 specification (e.g. bhp , torque , power/weight , MR/FR/FF..... , weight , etc..) . it's a combination of all wich determins that.

good examples are :

the ginetta G4 (93hp/450kg) wich won't win against any 300hp/1500kg car though its power/weight ratio is better. or an 800 hp muscle car getting beaten easly by a 500hp 4wd.
 
oh my god, where did this dinosaur come from? cant even remember my original reply. must have been pretty worse for wear....

But on a different standpoint, there will be some Tuning Cars in the game. Luggnuts, you may want to check the GT4 Gallery from E3. There is a Shigeno Version of the AE86 that features a carbon-fiber hood. I want to say the Trial Celica has one too, but I'm not sure.
Click to expand...

the Trial celica does have a cf hood.. it's painted though.. just like a lot of other japanese tuner cars.
 
Why so many "outdate" people reply to this thread? It's already anwser so...
 
whats wrong with cf hoods, i think they looks awsome.

and u can have the most power in a race, doesnt garentee a win, u need every thing else to go rite EX. pwer to the ground :dunce:

just thought to reply to something that i had answer to, just thought to put in my thoughts as to something that was asked or brought up in this thread.. so if you don't like to see this thread staying up top, you can choose to ignore and not reply also.

Or at least if you're going to reply, you can choose to stay in topic, thanks.
