How can I smooth the rotation using quaternion and raycast?

I’m trying to create Arcade Car Controller and my main problem is to rotate car’s model smoothly. How can I do this? Here’s my code:

if (Physics.Raycast(ray, out hitInfo, 2.0f, GroundMask))
{
        kartModel.rotation = Quaternion.FromToRotation(transform.up, hitInfo.normal) * transform.rotation;
}

If somebody interested I solved the problem using Lerp instead:

if (Physics.Raycast(ray, out hitInfo, 2.0f, GroundMask))
        { 
            kartNormal.up = Vector3.Lerp(kartNormal.up, hitInfo.normal, Time.deltaTime * 8.0f);
            kartNormal.Rotate(0, transform.eulerAngles.y, 0);
        }
