Even though four-door convertibles are practically extinct these days, most true car lovers still regard them as the pinnacle of open-top luxury. Once both popular and common, the four-door convertible class slowly started to disappear after World War II. The reason was simple since four-door convertibles have problematic torsion rigidity due to their construction. A long and open-top car makes the body twist, which is not pleasant.
Back in the â30s when cars had those sturdy, ladder-type chassis, the four-door convertible was a popular option. But when cars moved to unibody structures, this body style didn’t work anymore. However, some manufacturers still produce four-door convertibles. So read on to learn about the most interesting and obscure four-door convertible models.
Duesenberg was one of the most famous and sadly, discontinued luxury manufacturers known for combining superb quality with big power. Their SJ and SSJ four-door model, which was available as a convertible, they built in the late â20s and early â30s were among the fastest cars of the period. And that was due to the big straight-eight engines they used with a supercharger. Interestingly, the output ranged from 260 to as much as 400 HP in SSJ trim.
