特斯拉美股盘前升幅扩大至5%，此前公司发布了期待已久的Roadster跑车。
特斯拉周四在美国得克萨斯州麦格雷戈SpaceX测试基地举办Roadster的发布会，这是该公司首款可实现自主升空并控制姿态的量产乘用车。
这款Roadster跑车使用了SpaceX支持的火箭助推器，依靠空气驱动。该系统使用一个超高压气罐来存储260公斤压缩空气，该气罐取代了后排座椅。
与此同时，Roadster车身周围布置了十个喷嘴，喷嘴产生的推力足以使车辆悬停、绕多个轴旋转，并辅助特斯拉所谓的“短脉冲飞行”。
演示中，这辆Roadster跑车在一个U型滑道上完成了一次完整的翻转。演示车辆先驶上弯曲的坡道，利用推进器脉冲完成翻转，然后平稳地降落回地面。
