    Requested to move to a new thread from "10/20/2007 Demo"

    I've been doing a little test with all cars to see how they feel. I used Sixaxis, Manual Transmission, Simulation Mode, no ASM or TCS, S2 tires.

    Nissan GT-R
    [​IMG]
    To begin with, it's really fast. Just a few seconds after the start i'm bumper to bumper to the car in front (Lexus IS F). It understeers a bit but giving full throttle increases the grip slightly. Entering a corner too fast can be solved by slightly pull the e-brake, although that move will cost a second or two. Overall it's easy to drive for a car with that amount of power.

    Subaru Impreza WRX STi
    [​IMG]
    This car is an expert on hairpins and slow corners, turns quickly and keeps the balance controlled. Although when it comes to medium and fast corners it tends to understeer. Saving the understeer with the e-brake is not to think of in this car, it will spin out. It's fun to drive and play with but it isn't really a racer, after all it's made for dirt.

    Lexus IS F
    [​IMG]
    This big four door luxury beast needs a guru behind the wheel. It tends to oversteer at all speeds, hairpins and slow corners needs to be tackled with care. Fits very well as a drifter, except the automatic gearbox which takes the sportyness away and that when you pull the e-brake it sometimes stays in neutral for a few seconds. It's fast and beautiful and a real challenge to drive.

    Mazda Atenza Sport
    [​IMG]
    This car has exceptional cornering. Very good balance at all speeds. It is a little slow and requires some slip stream. But it compensates the slow straights in the corners.

    Daihatsu OFC-1
    [​IMG]
    This little fellow that almost fits in your pocket has very good handling. Even thought it's not very fast and don't have much power it's very fun to drive.

    BMW 135i Coupe
    [​IMG]
    This little beemer is very fast, but it has issues with the cornering. Every motion need to be very delicate to keep it on the road at high speeds. But driven with the right technique it can outrun the japanese sports cars.

    Mitsubishi Lancer Evolution X
    [​IMG]
    The Evo is very tweaky but it's very good with corners at all speeds. But watch out when you break before a corner as the tweaks will try to send it into a slalom motion.

    Nice! I would add that if you engage hand-brake with lexus, it loses gears for awhile. That is bad if you are trying to drift.

    Also, if you don't mind I'm going to quote your kikie's (just realized I confused your GTP ID with kikie) great post on each demo car's transmission/wheel support as it too will be a very useful reference for future GTP visitors:

    After driving all of the cars in the demo I must say my favourite is the BMW 135i Coupe, it's both fast and handles quite well. I hope PD carries the hatchback version over to GT5 as well.

    I thin k the nissan skyline is my favourite one on there because of it handling and its speed i reckon its a beutiful car to drive on there.
    I wish u could drive the f430 on there coz its a gorgeous car

    The evo Lancer one is another good car but yeh a bit t:)weaky on the corners

    i cant wait for the whole game and test all of the cars

    The F430 is kinda like the big one for this game. I can only dream of a top tuned F430 in a GT game. :drool:

    A lot of people don't know what understeer is. In most cases, understeer happens when you turn in to a corner at a speed that is too high. The front wheels lose grip and the car slides over the front wheels straight to the outside of the turn. You try to turn the car even more, which is wrong because the force on the tires exceed what they can handle in a turn, and they lose even more grip.

    Let me first explain what a "skid", "slip" means. A slip of a car occurs when the speed of one or more wheels of the car is lower (e.g.: when you apply the brakes too hard, the wheels turn around slower or stop completely than the car travels onto the road) or faster (e.g. applying too much throttle when you start to accelerate, the wheels are spinning which means that the wheels are turning faster than the car travels onto the road) than the speed of the car itself in regard to the road.

    So:

    * Let go off the throttle to reduce the speed of the car, to shift the weight of the car onto the front wheels so they get more grip.

    * Most people, and this is a natural manoeuvre, apply more steering (they try to steer even more, which is wrong) when they experience understeer. You have to do the opposite. "Open" you steering wheel and reduce steering (straighten out the wheels of the car as much as possible, ofcourse not entirely, because you still have to turn).

    * Never apply more throttle to "cure" understeer. This will only cause more slip.

    * Use the e-brake only as a last resort if the other "techniques" didn't work.

    Every car, RWD, FWD, AWD, experience understeer. A FWD car has more tendency to understeer, because the front wheels must endure two different force ==> acceleration or braking and at the same time, turning.

    An AWD has also the tendency to understeer but less than the FWD.

    Not to brag or something but just to let you know that I know what I'm talking about :sly:

    This is where I learn how to control a car.

    click here

    EDIT: I forgot to mention, if you let go of the throttle to shift the weight of the car to reduce understeer, you also could apply the brakes a very little bit. It reduces the speed even more and transfers the weight even more onto the front wheels.

    I agree with kikie that A lot of people don't know what understeer is. I digress.

    Great post again.

    BTW: For those curious about learning more about understeer and oversteer, there have been several threads on the subject throughout GTP forums, like Oversteer or Underseer - What do you Prefer?. Also wikipedia's listing for Car Handling is a great jumping off point for researching far more detailed explanations on not just understeering and oversteering, but much more. :tup:

    I must have missed something... either the ;) missing from that post, or the press release that ever said the F430 was going to be one of the cars available to drive in the demo.

    If neither of those shows up, I'm going to go out on a limb and suggest that you overlooked that this thread is about driving the cars in the demo. Seeing as the full game for GT5:p isn't out yet it would be difficult for any of us to offer any personal opinions on how the Ferrari F430 drives in the game. :tup:

    The physics engine has definitly improved, the difference between the handling/personality of the cars is very noticeable and makes for a realisitc driving experience

    However I found that the Subaru Sti will oversteer exiting medium speed corners if you trust the car and apply throttle on the exit. It won't push and go straight but rather it will oversteer

    The Lexus IS F is a dog, but I believe the idea there will be cars that handle like this in GT5 is great. If every car had decent to great handling then there would be no variety and no challenge.

    Yes. I can only dream of F430 Scuderia in GT. Scuderia clocked faster time than enzo in ferrari's test track.

    Unfortunately, anyone who's played GT4 is going to be only too familiar with understeer. :grumpy: An occasional oversteer would be nice! :) not to mention more realistic tire physics & weight transfer. Braking under cornering & recovering from mistakes are just way too easy in GT4. Please , please tell me these have been significantly improved in the GT5:p demo. :nervous:

    It is way better. Drifting is much easier when you are on limit. I have no complaints with physics.(exc. colision/damage)
    GT5:prologue is the most impressive racing game i ever played.

    I would also recommend the following book if you're serious about improving your driving techniques in both games and on the street/track:

    http://www.amazon.com/Sports-Compet...5702218?ie=UTF8&s=books&qid=1193754192&sr=8-2

    Concepts of over- and understeer are explained simply, and then expanded upon to show the physics involved in grip and car control.

    :tup::tup: Great recommendation.

    Since we are into books. These are the two that is on my shelf:

    Personally I would stay away form the wiki stuff and also there is a so called "Setup Matrix" floating on the net that contains a full section of wrong information. :nervous:

    Thanks for the link! I'm going to find this book in a local book shop, because I don't have a credit card and I can't buy stuff online. :(

    This is what I found about the author, which is a former Belgian F1 driver: Wikipedia

    I don't see the info in your post, but Paul Frere has an impressive racing resume for sure. I own that book, and it's a good read in addition to having good technical detail. It has been updated recently to cover new technology such as ABS, traction control, AWD, etc. The fundamentals of racing, such as line selection, passing, grip, etc. really haven't changed since the author raced professionally, so his thoughts do still hold relevance.

    The following is based off of Professional Physics

    I can assure you this demo is a major step forward for the Gran Turismo franchise

    As kekke2000 said, the Lexus IS F oversteers at all speeds and can be a handful. But taming the beast can be an enjoyable challenge.

    I found the the Subaru STi to oversteer when entering corners at high speeds or exiting corners at medium speeds. It's oversteer is not as dramatic as the IS F but definitly noticeable. All cars do not oversteer though, which is realistic, the Nissan GT-R ranges from Neutral to understeer. But some cars do oversteer now, that is a fact.

    If you brake while cornering in GT5:p the demo you will either break the backend loose and spin out if you are on entry or you will simply slide the front tires if you are on exit.

    As for recovering from mistakes I can tell you in GT5:p the demo it is both tougher AND easier to recover from mistakes. If you try and throw a car around the course like you would in previous GT games you will find yourself spinning out no doubt. You definitly will find yourself at first tip tiptoeing around the track until you find the limit of the car. Each car does everything a little different, so this takes a while.

    It is also easier to recover from certain mistakes as I noticed several times. For the first time ever I drifted a car, but it was unintentional. I was exiting the first corner in the Nissan GT-R when I got on the gas too hard and the back end stepped out. I didn't want to get out of the gas so I fought with the wheel and what do you know, the car difted for a bit and after wiggling the backend it straightened up and I was on may way. The whole thing looked and felt realistic. I was very impressed. All of this would never happen in GT4. I would know, as I still drive GT4 to this day regularly. Sadly, everytime I do drive GT4 I am reminded as to how vastly inferior it is to the GT5:p demo in every aspect.

    No incar view, no oversteer, tons of understeer, stupid AI that runs you off the road, and not much of a challenge driving the cars.

    Believe me when I say GT5:p is a very, very big improvement over Gran Turismo 4.

    So very true, I couldn't agree more. The GT5:p Demo we have is so much more challenging as mistakes are often much more punishing such as braking just that bit to late, or missing the apex of a corner. But being a little to throttle happy can often end up in a rewarding slide rather then finding the back end overtaking the front.

    I noticed that too with the STi between the first two corners. If you get too much angle before braking, the rear tires will lock and it will go straight to the sand. Never experienced this in GT4. Very realistic indeed.

    Kekke, just curious, when you say that the rear tires lock, a physical stop of rotation lock? or the rear sliding as mentioned above.

    must agree with a few others regarding the sti. i have had on a few occasions drifted my way around the first 2 corners. I remember thinking "oh no sand trap" then managed to hold it through the corners with a nice amount of smoke and an excellent replay to boot

    I don't know, it's just how it feels.

    Yes thats what i'm talking about, it's a fun car to play with but not a racer.
