The first of these in the modern era came out in 1949: three midyear models from GM. They were in essence convertibles with steel tops welded on. Four-door models arrived a few years later, and by then the cars were designed as hardtops, not retrofitted convertibles. There are similar pillarless top designs, however, dating to 1916... Hardtops and sedans, with 2 and 4 doors, all have B-pillars, as this is what the door lock (latch) attaches to. It's just that in the hardtops, they do not visibly extend above the windowline, and are thus partial B-pillars. And, to the original question, the removable rigid roof you can put on some convertibles is also called a hardtop. Chris in LA
