How to add car speed to a car controller script

Question

Hello

Im very new to unity and coding I have a car controller script and would like to able to change the speed the car goes does anyone know a script I can add

so at the moment my code allowd to move foward and back and tern left and right

[code=CSharp]using UnityEngine;

public class Car : MonoBehaviour { public float maxTorque = 5000000f;

 public Transform centerofMass;

 public WheelCollider[] wheelColliders = new WheelCollider[4];
 public Transform[] tireMeshes = new Transform[4];

 private Rigidbody m_rigidBody;

 void Start()
 {
     m_rigidBody = GetComponent<Rigidbody>();
     m_rigidBody.centerOfMass = centerofMass.localPosition;
 }

 void Update()
 {
     UpdateMeshesPositions();
 }

 void FixedUpdate()
 {
     float steer = Input.GetAxis ("Horizontal");
     float accelrate = Input.GetAxis ("Vertical");

     float finalAngle = steer * 45f;
     wheelColliders [0].steerAngle = finalAngle;
     wheelColliders [1].steerAngle = finalAngle;

     for (int i = 0; i < 4; i++)
     {
         wheelColliders[i].motorTorque = accelrate * maxTorque;
     }
 }

 void UpdateMeshesPositions()
 {
     for(int i = 0; i < 4; i++)
     {
         Quaternion quat;
         Vector3 pos;
         wheelColliders[i].GetWorldPose(out pos, out quat);

         tireMeshes[i].position = pos;
         tireMeshes[i].rotation = quat;
     }
 }

} [/code]

you multiply your variable "accelrate" by another variable you need to add to your script or change maxtorque

 wheelColliders[i].motorTorque = accelrate * maxTorque *newVariable;
