1963 Pontiac Catalina 1963年龐迪克Catalina

????無(wú)支柱式硬頂或硬頂敞篷車(chē)在設(shè)計(jì)上省去了車(chē)前門(mén)后的車(chē)頂支撐件,，因此看起來(lái)像一輛車(chē)頂抬升起來(lái)的敞篷車(chē),。部分類(lèi)似龐迪克（Pontiac）的車(chē)型則將敞篷理念做了更進(jìn)一步的發(fā)揮，將車(chē)頂設(shè)計(jì)得宛如一個(gè)抬升起來(lái)的帆布車(chē)頂,。這種設(shè)計(jì)所潛藏的安全性問(wèn)題以及在新型單片式車(chē)身生產(chǎn)線上遭遇的生產(chǎn)難題導(dǎo)致無(wú)支柱式硬頂車(chē)型在1978年宣告壽終正寢,。

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.
