用构造函数创建对象汽车

<script>
    var car = new Object();
    car.make = "比亚迪";
    car.model = F6;
    car.currentSpeed = 50;
    car.displacement = 2;
    //启动引擎
    car.Startengine = function () {

    };
    //启动
    car.startup = function () {

    };
    //加速
    car.changeSpeed = function () {

    };
    //转向
    car.swerve = function () {

    };
    //刹车
    car.stop = function () {

    };
    //关闭引擎
    car.Turnofftheengine = function f() {

    };
