The 356 C replaced the 356 B in September 1963. The choice of engines was reduced to three, and the previous 60-PS variant was dropped. Instead, the 75-PS unit used in the B 1600 Super became the entry-level engine for the C series. The most powerful engine, found in the 356 C 2000 GS Carrera, produced 130 PS.
In visual terms, the C series was very similar to the B series. A noticeable change was the modified rims, which had flatter hub caps without the Porsche Crest. The new hub cap design was introduced because all 356s were now equipped with disc brakes as standard. The C-series also featured round exterior mirrors.
The final Porsche 356 C was delivered in May 1966.
All 356s were also available in open-top versions (Cabriolet, Speedster or Roadster).
From the 356 A onwards, particularly sporty variants were given the additional "Carrera" designation and were powered by a Fuhrmann engine.
The engine, named after the designer Ernst Fuhrmann, was characterised by four overhead camshafts that were driven by vertical shafts. What's more, this engine had dual ignition via two separate ignition distributors.
