1963 Pontiac Catalina 1963年庞迪克Catalina

    无支柱式硬顶或硬顶敞篷车在设计上省去了车前门后的车顶支撑件，因此看起来像一辆车顶抬升起来的敞篷车。部分类似庞迪克（Pontiac）的车型则将敞篷理念做了更进一步的发挥，将车顶设计得宛如一个抬升起来的帆布车顶。这种设计所潜藏的安全性问题以及在新型单片式车身生产线上遭遇的生产难题导致无支柱式硬顶车型在1978年宣告寿终正寝。

1963 Pontiac Catalina

    Pillarless hardtops or hardtop convertibles, which omitted the roof support behind the front door, were designed to look like a convertible with the top raised. Some, like this Pontiac, took the convertible look even further, shaping the roof to resemble a raised canvas top. Safety concerns and manufacturing difficulties with new unibody assembly spelled the end of the pillarless hardtop style by 1978.
