Car does not move

I was making a car game by watching a tutorial (#3 How to make a Car game - Unity 3D Tutorial - Basic Movement - YouTube)
and i did everything as said, but when i press w or arrow keys, the car dowsn’t move, instead it slides ahead real slow on its own. i am using c# instead of js. please help

Well i didn’t do the tutorial but unless you changed “Vertical” in the input manager to “w” this won’t work.
If you didn’t, use Input.GetAxis (“Vertical”); instead of “w”. The reason why it slides real slow is because GetAxis returns a small value like -1.0f or 1.0f. That’s way to small for a torque. What you usually do is multiply that value with the MaxTorque.
So unless you changed “Vertical” to “w” it should look like this:

WheelBR.motorTorque = Input.GetAxis ("Vertical") * MaxTorque;
WheelBL.motorTorque = Input.GetAxis ("Vertical") * MaxTorque;

here @JedBeryll

using UnityEngine;
using System.Collections;

public class CarController : MonoBehaviour {
public WheelCollider WheelFL;
public WheelCollider WheelFR;
public WheelCollider WheelBR;
public WheelCollider WheelBL;
public float MaxTorque=50.0f;
// Use this for initialization
void Start () {

}

// Update is called once per frame
void Update () {
	WheelBR.motorTorque = Input.GetAxis ("w");
	WheelBL.motorTorque = Input.GetAxis ("w");
	WheelFL.steerAngle = 10 * Input.GetAxis ("Horizontal");
	WheelFR.steerAngle = 10 * Input.GetAxis ("Horizontal");
}

}
