The Porsche 356 was launched in 1948 as the first production model of the sports car brand from Zuffenhausen and is also known as the “original Porsche”. The first series (“Pre-A”) was produced until 1955. In October of that year, the 356 A was presented as a modified successor. The successful Porsche 356 series was continued until 1965 in the development stages B, C and SC. The engine was always an air-cooled four-cylinder boxer. The available body styles were Coupé, Cabriolet, Hardtop Coupé (by Karmann), Speedster and at times Convertible D (later Roadster). It was not until 1963 that the 356 was replaced by the Porsche 901/911. The 356 B model was introduced in autumn 1959 as a further development of the A.
Modifications included asymmetrical headlights and the front wing housings ran slightly slimmer. The bumpers were raised to allow air intakes in the front apron for the new alloy drum brakes and to meet US requirements. In addition, the seats, transmission, brakes, electrics and engines were revised. The tried and tested pushrod engine always had a displacement of 1.6 litres, which was available in three power levels: 60 hp (1600), 75 hp (1600 S) as well as 90 hp (1600 Super 90), generated by different compressions and different carburettor types.
Roadster variant: The open Convertible D was already available in the 356 A model from 1958 onwards and is to be placed between the puristic Speedster and the mature Cabriolet. The Convertible D differs from the Speedster in having a higher windscreen (but lower than the Cabriolet), a soft top with a larger rear window, crank windows and normally upholstered seats instead of the bucket seats. The “D” stands for Karosseriewerk Drauz in Heilbronn, which produced this body variant. With the modification to the B model, the Convertible D was designated “Roadster” from model year 1960, and was offered in all three engine variants of the 1600. Later, production of the Roadster took place at the coachbuilder D’Ieteren in Brussels until the model was discontinued in 1962. In total, only 2,902 examples of the 356 B with a Roadster body were produced from 1960 to 1962.
