    1:  Introduction
    Many sports devise a formula to rank all players against each other, so
    one can determine who the "best" or "most complete" player is in any
    particular sport.  This is typically called a Power Ranking.  
    With so many cars featured in Gran Tourismo, with often just miniscule 
    differences in their performance characteristics, a Power Ranking would 
    give anyone playing the game a very good way to determine how "good" a 
    car would be, or what the "best" car would be to use in simulation mode 
    against cars picked by the AI.
    Similar to sports where there are long and on-going discussions about
    the formulas used to determine the best players, I certainly realize 
    that the Power Ranking Formula can be considered subjective or might not
    yield the results you expect.  Based on your driving style, you might win 
    easily against a car that is ranked higher than yours.  Yet, the Power 
    Ranking gives you at least pointers on potential performance of all the
    cars, thus making it easier for you to select a car well suited for what
    you want to accomplish.
    However, it is unavoidable that some cars will be over-rated or 
    under-rated, since no single formula can be devised that will rank
    each and every car exactly right compared with other cars.  Thus, you
    might want to take this ranking with a grain of salt.  For a good
    example of an over-rated car, look no further than the Suzuki Escudo.
    Yes, it will allow you to blow away the competition on the Test Track
    or the Super Speedway, but its handling is extremely difficult, so you
    will certainly struggle with it racing Cote d'Azur or the Corkscrew in
    Laguna Seca.  Yet, it will deliver a basis for comparing different cars.
    And it will provide all of us an "objective" basis to discuss the
    performance of certain/all cars.
    2:  Why bother?
    Since most of us upgrade and/or tune our cars extensively anyway, why
    bother writing this FAQ?
    There are two reasons for doing so:
    1. Initially, when you are new to the game and have only a limited
    number of cars available to you, the Power Ranking numbers can help you
    to pick the right starter car, or even you second car.  Also, you might
    have limited funds for upgrades initially, so again, picking the right
    car as your second or third car might be crucial
    2. Later in the game, despite having a lot of money available for
    upgrades, you will mainly race F1 or Race Cars.  While you can tune these
    cars, there are not too many upgrades available for these cars, so the
    Power Rankings might matter to you.
    3:  Power Ranking Formula
    Thanks for all the feedback on my Power Ranking Formula.  Most of the 
    feedback pertained to the Cornering/Handling section of the formula,
    so for version 2 of this FAQ, I revised this portion of the formula.
    See below for an explanation.
    The New, Updated Power Ranking Formula is:
    Power Ranking Value = 
    1/HP-WeightRatio * 2/36 + 
    1/((3*HP-weightFactor + 7*Torque-WeightFactor)/10)
    * (1 + Tuning Factor) * 34/36 + 
    1 * (1 + Tuning Factor) * 2.5 + 
    1 * (1 + DrivetrainUpliftFactor) * 1.5 + 
    1 * (DriveTrainUpliftFactor * (2* (Front Downforce +
    Back Downforce)) + (100 - Front Height - Back Height)/400) * 
    (1 + TuningFactor) * 1.5
    The Power Ranking Formula will be applied only to "stock" cars (cars
    that you can buy from the car dealership, not tuned, not upgraded), 
    or to cars that you win at the end of a race or championship.  Once you
    tune or upgrade the car, the ranking would change.  Invariably, 
    upgraded cars are not considered or featured in the Power Ranking.
    The following three major components influence your racing experience 
    the most:
    - Power/Acceleration
    - Braking
    - Cornering/Handling
    Thus, all three areas are weighted equally in the Power Ranking Formula:
    Power Ranking Value = 
    Power/Acceleration Performance + Braking Performance +
    Cornering/Handling Performance
    Tuning Factor
    While many of the stock cars are not tuned and you have to tune them
    yourself (your tuning is not considered in the Power Rating Formula),
    many of the cars you can win in the professional level races are
    Road Cars or Race Cars and are tuned (well balanced with respect to
    acceleration, braking, cornering, handling).  Thus, a Tuning Factor of
    20% uplift was applied to all F1 cars and road and race cars (cars that
    typically come with Medium tires and most/all upgrades applied).  All
    stock cars received a tuning factor of 0%.
    Power/Acceleration Performance
    The Power/Acceleration Performance consists of two parts:
    Power Performance and Acceleration Performance.
    Power Performance
    While the sheer power of a car is important, the power/weight ratio
    better exemplifies the power performance of a car.  Ideally,  
    everything being equal, the more horsepowers your car has, the faster
    it can go.  Also, the lower your power/weight ratio, the faster your
    car can go (again, everything being equal).  However, in GT3, there
    are only two out of 36 tracks where sheer power (thus, HP/weight
    ratio) matters:  Super Speedway and Test Course.  Thus, the Power
    Performance is computed as  1 divided by HP/Weight ratio and multiplied
    by its relative weight (Power Factor) of 2/36.
    Power Performance = 1/HP-WeightRatio * 2/36
    Acceleration Performance
    Acceleration is very important for racing most of the tracks in GT3.
    The curvier a track is, the more important acceleration will be.
    Often, when tuning a car, the first adjustment one makes is the gear
    shift ratio to set the optimal setting for acceleration vs. high speed.
    On a track like Cote d'Azur or Laguna Seca, you hardly ever reach the
    top speed of the car, while on the Test Course, acceleration hardly
    Acceleration is influenced mainly by the torque-weight ratio, but also
    by the HP-weight ratio (HPs also influence the torque-weight ratio).
    Thus, 7/10 of the acceleration factor is influenced by acceleration
    (torque-weight factor), whereas 3/10 are influenced by the 
    HP-weight factor.  
    Tuning of the car also plays a role, so the Tuning Factor (see above)
    was applied in the formula as well.  Since Acceleration matters pretty
    much in 34 of 36 races, its relative weight (Acceleration Factor) was 
    set to 34/36.
    AccelerationPerformance = 
    1/((3*HP-weightFactor + 7*Torque-WeightFactor)/10)
    * (1 + Tuning Factor) * 34/36
    Since there is no braking data in GT3, the braking Factor was set to 1,
    meaning that all cars have adequate braking for the power they have
    (actually, when racing, e.g., the Suzuki Escudo, you will find out that
    it does not have adequate braking power, but I did not want to use a 
    subjective factor to braking).  Braking is also influenced by Tuning,
    so the Tuning Factor (see above) was applied.  To give braking the same
    weight as power/acceleration has, an uplift factor of 2.5 was applied
    BrakingPerformance =  1   * (1 + Tuning Factor) * 2.5
    Note: While the braking force can be influenced and tuned, the preset for
    all cars is Level 9 in the front and back, thus it could not be considered
    for the formula.
    Cornering / Handling
    The Cornering/Handling performance is influenced by both the cornering
    abilities of a car and the way it handles in general.  For both
    cornering and handling, an uplift factor of 50% was assigned to each
    category to equally weigh the sum of both with Braking and
    Power/Acceleration Performance
    Cornering Abilities
    Revision: Upon your feedback, I included the downforce settings and
    the suspension height setting in the formula.  Other settings, such
    as cambio angle, seem to be always preset to 2.0 in the front and 1.0
    in the back, so I did not consider them, since they are the same for
    all cars.  You have to purchase the full suspension upgrade in order
    to see the suspension height setting.  I used the factory setting for
    all cars.  Downforce cannot be "unlocked" by any upgrade, so either it
    is visible and can be changed (typically for F1, race cars and rallye
    cars, but also for some cars like the Mitsubishi Lancers) or it is
    invisible and cannot be changed.  However, I noticed that the makers of
    the game seem to have used "pre-settings" for different classes of cars,
    e.g., all F1 cars have at least a downforce of 0.70 in the front and
    1.3 in the back.  All Rallye cars have downforce factory settings of 
    0.45 and 0.66 whereas Race cars typically have settings of 0.66 and
    0.81.  Thus, for cars without visible settings, I put them into 
    certain buckets (e.g., small cars, sporty cars or muscle cars) and
    assigned pre-defined downforce values.
    So the new cornering formula looks like the following
    Cornering Ability = DriveTrainUpliftFactor * (2* (Front Downforce +
    Back Downforce)) + (100 - Front Height - Back Height)/400
    This puts the main emphasis on the Downforce and keeps the Height
    Factor pretty small, typically at less than 10% of the Downforce
    Old part of the formula: NO LONGER VALID
    No details are provided in GT3, but in general, cornering abilities
    depend to a certain extend on the drive train.  FF cars generally have
    a larger turning radius than FR cars.  FF cars have a tendency to 
    understeer a lot, whereas FR cars are more prone to oversteer.  4WD and
    MR cars have pretty solid cornering abilities with a tendency to 
    under- or oversteer less than FF and FR cars do.  Thus, uplift factors
    were assigned to drive trains as follows: 
    FF: 0%; FR: 2.5%; 4WD: 10%; MR: 15%
    The formula thus looks like
    Cornering Ability =  1   * (1 + DrivetrainUpliftFactor)
    Again, no details are provided, but in addition to the Drivetrain
    UpliftFactor (see cornering), tuning also plays a role, so the
    TuningFactor was applied as well.  Thus, the formula looks like this
    Handling Ability =  1   * (1 + DrivetrainUpliftFactor) * (1 + TuningFactor)
    Thus, the overall Power Rank value is determined as:
    Power Ranking Value = 
    1/HP-WeightRatio * 2/36 + 
    1/((3*HP-weightFactor + 7*Torque-WeightFactor)/10)
    * (1 + Tuning Factor) * 34/36 + 
    1 * (1 + Tuning Factor) * 2.5 + 
    1 * (1 + DrivetrainUpliftFactor) * 1.5 + 
    1 * (1 + DrivetrainUpliftFactor) * (1 + TuningFactor) * 1.5

    As expressed in the intro, the Power Ranking is subjective and certainly
    debatable.  Thus, please send me your feedback, but without flaming me.  
    I will try to publish as much feedback as possible, plus I'm open to
    revising the formula based on your input.
