vehicleAxes

Sets the address of individual axis entities in the file. These are numbered in sequential order from front to back, meaning that on the 4WD vehicles PhxVehicleAxis0000 is the front axle and PhxVehicleAxis0001 is the rear axle.

torqueDistributions

This is unused in all vehicle .fpkd archive .veh files, but values can still be edited in. This property sets the amount of power being sent to each axle. The arraySize should be set to the number of PhxVehicleAxis properties in the .veh file and final sum of distribution values should be equal to 1 (100%). Values set the power given in decimal percentages. Like with the PhxVehicleAxis numbering, these are in sequential order from front to back.

e.g. For 30% of power being given to the front axle and 70% to the rear axle on a 4WD vehicle:

<property name="torqueDistributions" type="float" container="DynamicArray" arraySize="2">
  <value>0.3</value>
  <value>0.7</value>
</property>

gearRatios

This is another unused property found in all vehicle .fpkd archive .veh files. Values here can also be edited in. It sets the gear ratio of each vehicle gear. The number of gears a vehicle has can be determined by listening to the number of upshifts a vehicle makes in game from a complete stop to full throttle top speed. The gist of what gear ratios in the real world do is that higher gear ratios give faster acceleration at the cost of lower top speed while in that gear, and lower amounts are the inverse (hence why your vehicle may go from 0-30 in a few seconds but 70-85 takes much longer).

Standard gear ratios are n:1 but the property simply takes n for the value. For a 4WD vehicle, which has three gears, with sequential gear ratios of 2.5:1, 1.5:1, and 0.7:1 you would do:

<property name="gearRatios" type="float" container="DynamicArray" arraySize="3">
  <value>2.5</value>
  <value>1.5</value>
  <value>0.7</value>
</property>
