how to set initial speed of vehicle

Question

Hi,

I want to start my car with some initial speed say 500 and want to run it at very high speed. below is my script snippet void update() {

     FrontLeftWheel.motorTorque = Torque;

     FrontRightWheel.motorTorque = Torque;

}

I want to achieve the result same as if I would get by translating a rigidbody (e.g. code below)

void update { CarBody.transform.Translate(Vector3.forward); }

I am putting the mass of the car as 1000 and of wheel is 20 and tried with torque from 200 to 10000 nm.

my unity version is 5.0.0f4

Thanks for any help.

Just set the speed of the car's rigidbody, and let the rolling rotate the wheels up to speed:

 void SetSpeed(){
      CarRigidbody.velocity = new Vector3(30,0,40);
 }
