In model year 1956, the 356 was replaced by the comprehensively enhanced 356 A. As from its market launch, this type was available with five four-cylinder engines:
- 356 A 1300 with 44 hp
- 356 A 1300 Super with 60 hp
- 356 1600 with 60 hp
- 356 A 1600 Super with 75 hp
- 356 A 1500 GS Carrera with 100 hp
The modifications to the vehicle were part of "Technical Programme 1" (T1). One of the key visual differences between the A series and the original 356 was a single-piece, curved panoramic windscreen. The front indicators were always integrated in the horn grille and all models had a modified front lid handle with inset Porsche Crest. The tail lights were teardrop-shaped as of 03/1957.
The 1300 models were discontinued in model year 1958 (T2). The tailpipes of the 1600 models ended between the bumper guards to give more ground clearance. The chrome-plated housing with number plate lighting and reversing light was mounted below the number plate.
All 356 generations were also available in an open-top version (Cabriolet, Speedster or Convertible D).
From the type 365 onwards, particularly sporty versions were given the additional designation "Carrera" and were powered by a Fuhrmann engine.
This power unit, named after designer Ernst Fuhrmann, was characterised by four overhead camshafts, which were driven by bevel-gear shafts. The engine also featured a dual ignition with two separate distributors.
