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 ‘30s 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.
15. Duesenberg SJ
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 ‘20s and early ‘30s were among the fastest cars of the period.
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.
