Porsche 356 B (1959 to 1963)

In late 1959 significant styling and technical refinements gave rise to the 356 B (a T5 body type). A unique "Karmann hardtop" or "notchback" 356 B model was produced in 1961 and 1962. The mid-1962 356 B model was changed to the T6 body type, sporting twin engine lid grilles, an external fuel filler in the right front wing/fender, and a larger rear window in the coupé. Notably, the Porsche factory did not call attention to these quite visible changes with a different model designation. However, by late 1963, when the T6 got disc brakes, with no other visible alterations, they called it the 356 C.
