1956 - 1959 Porsche 356s

The first major revision of the 356 occurred in 1956, with the 356A. Its curved, one-piece windshield was accompanied with expanded head and leg room. Wheels were reduced in diameter (from 16 inches to 15 inches) and increased in width to 4.5 inches. Significant suspension improvements furthered the car's modernization.

The Convertible D was released in 1959 as a more practical alternative to the Speedster, with taller windshield, roll-up windows, and reclining seats. For its advancements over the comparatively primitive 356, as well as its sleeker, more "vintage" lines (compared with the 356B and 356C), the A is revered among Porsche enthusiasts.
