Casco vs Ztype (Handling data)

[Tez2]

Hey everyone.

I'm comparing casco with ztype. The ztype is the fastest vehicle in-game because of it's drag.

Mass

Casco

<fMass value="1100.000000" />

Ztype

<fMass value="1000.000000" />

The casco is a little bit heavier than the ztype.

Drag

"How aerodynamically efficient a car is (how much drag it produces). Higher numbers mean higher drag, and less aerodynamic efficiency. Aerodynamic efficiency affects how well a car gets up to its top speed, and causes the vehicle's actual top speed to be lower than the one specified in the handling.meta"

Casco

<fInitialDragCoeff value="8.000000" />

Ztype

<fInitialDragCoeff value="6.000000" />

Now we move to transmission attributes.

"Rate of acceleration is determined by fDriveBiasFront, nInitialDriveGears, fInitialDriveForce, fDriveInertia, and fInitialDriveMaxFlatVel"

"Rate of deceleration is determined by fBrakeForce and fBrakeBiasFront"

"fSteeringLock can be thought of as a measure of sideways acceleration"

 

Gears

"The gear ratios are set by the game automatically, and are based upon how many gears there are (this value) and the top speed (see more on that below). Too few gears will cause the vehicle to accelerate slowly because of the low RPM's each gear starts at. Too many will cause loss of speed at higher speeds when the driver is constantly shifting. How many gears a vehicle has depends mostly on what kind of vehicle (sportscars can have 5-6, standard sedans usually have 4, some big rigs have more than 10, etc)."

Casco

<nInitialDriveGears value="5" />

Ztype

<nInitialDriveGears value="4" />

Drive force

"How much torque/power the engine puts out (thought not based on any sort of real-life measurement system). Naturally, more power means the car accelerates faster. More power also puts more pressure on the drive wheels, which affects launch speeds and handling. A vehicle with more power is more likely to spin it's drive wheels when the gas is applied, which can dramatically lower grip levels if the wheels spin unabated."

Casco

<fInitialDriveForce value="0.320000" />

Ztype

<fInitialDriveForce value="0.300000" />

Max Velocity

"This is the maximum velocity of the vehicle's transmission. This determines the length of the gears, which (along with number of gears and drive force) affects how fast the vehicle accelerates. The actual top speed is lower, and is affected by mass and drag."

Casco

<fInitialDriveMaxFlatVel value="151.000000" />

Ztype

<fInitialDriveMaxFlatVel value="154.000000" />

Brake force

"How much resistance the brakes create when fully depressed. What to set this value to depends on vehicle mass, potential speeds, and tire traction. If the brake force is too high, it can cause the tires to lock up and skid. This greatly increases stopping distance. Higher momentum (mass and velocity) and lower tire grip decrease the brake force required to lock up the vehicle's tires."

Casco

<fBrakeForce value="0.600000" />

Ztype

<fBrakeForce value="0.700000" />

Brake Bias Front

"How braking power is distributed between the front and back wheels. A value of 1.0 gives all braking power to the front wheels, whereas a value of 0.0 gives all the power to the back. Having brake power biased to the front helps when braking hard and entering corners, as it counters the understeer braking causes. Braking power biased to the rear makes a vehicle more stable when braking and helps it to stop in strait lines. Most cars use values within the range of 0.6-0.7."

Casco

<fBrakeBiasFront value="0.650000" />

Ztype

<fBrakeBiasFront value="0.500000" />

HandBrake force

"How much resistance the rear brakes create when the handbrake is applied. The handbrake is used to get a vehicle around a tight turn by sliding the rear end. It is important that this value is high enough for the rear wheels to lock up when the handbrake is applied. This varies between vehicles though, as some slow vehicles with a lot of traction may not lock their rear brakes up."

Casco

<fHandBrakeForce value="0.450000" />

Ztype

<fHandBrakeForce value="0.350000" />

Steering Lock

"This value is a multiplier of the game's calculation of the angle a steer wheel will turn while at full turn. Steering lock is directly related to over or understeer / turning radius. Values around 0.1 - 0.2 will simulate a long wheelbase. Whereas a value of around 0.75 and above will turn extremely fast. To high of a value here will cause the vehicle to spin out too easily."

Casco

<fSteeringLock value="38.000000" />

Ztype

<fSteeringLock value="40.000000" />

Traction Curve Lateral

"The angle at which the tires produce the most grip. The value is a angle / 10 (1.0 is 10^o, 0.9 is 9^o, 1.2 is 12^o, etc). A Curve Lateral set to 0.0 means the tires will produce the most grip when they are parallel with the direction they are moving, and 9.0 means the tires produce the most grip when they are perpendicular to the direction they are moving. When trying to be realistic, this value ought to be somewhere close to parallel (roughly 0.9). Setting it lower will make a vehicle enter corners very briskly, but then begin to understeer as the corner progresses. Setting it higher will do the opposite."

Casco

<fTractionCurveLateral value="20.500000" />

Ztype

<fTractionCurveLateral value="21.00000" />

Traction Bias Front

"How the traction is distributed between the front and back. Setting it to 0.99 gives all the traction to the front tires, whereas setting it to 0.01 gives the traction to the rear wheels. More traction in the front creates oversteer, while more in the back creates understeer. Unlike most 0-1 values, this cannot be set outside the bounds of 0.01-0.99, otherwise the wheels of the side with no grip will disappear."

Casco

<fTractionBiasFront value="0.490000" />

Ztype

<fTractionBiasFront value="0.489000" />

The actual top speed is lower than max velocity and affected by drag and mass.

Ztype actual top speed is higher than Casco actual top speed.

Less mass and less drag and higher max velocity.

However Casco acceleration is faster than Ztype acceleration.

I think this is a different version of "Massacro racecar vs Jester racecar" but with sports classic cars.

I guess Z-type is still the fastest vehicle in-game.

Big thanks to Grandtheftwiki and gtamodding

Awesome job, but you didn't bring the Pigalle into consideration, for races that actually require skill, it's still the fastest classic.
