Porsche 356 A, B and C: the main differences
Comparing Porsche 356 A, B and C models: bodywork, T1–T6 developments and brakes. Useful clues for identifying a version and assessing its consistency.
Key points
- A, B and C are families; T1, T2, T5 and T6 identify technical developments.
- The 356 B also changed during production: T5 and T6 must be distinguished.
- Two rear grilles alone do not identify a 356 C.
To distinguish Porsche 356s, start with the family and then narrow down to the version. A table helps with orientation but does not replace examining the car: parts from different series may have been fitted during repairs or conversions.
The three series compared
| Family | Introduction | Main clues |
|---|---|---|
| 356 A | September 1955 | Curved panoramic windscreen; development from T1 to T2. |
| 356 B | September 1959 | Front end with higher headlights and bumpers; first T5, then T6. |
| 356 C | September 1963 | Appearance close to the B T6; disc brakes as standard. |
The introduction dates come from the official 356 A, 356 B and 356 C model pages. They must not be confused with the first registration date of an individual car.
T1, T2, T5 and T6: why they matter
For the A, Porsche describes the T1 programme and subsequent T2. For the B, it distinguishes the T5 from the T6 introduced in September 1961: the latter has a changed front bonnet, fuel filling on the right front wing and two grilles on the engine lid. These are useful clues when comparing panels and openings, not a shortcut to certifying the entire car.
A parts list based only on the designation “356 B” can therefore be too general. When contacting a supplier or workshop, also include identification documents and photographs of the relevant detail.
Brakes: the rule and the exception
The C brought disc brakes as standard across the range. It would nevertheless be incorrect to say that no B had discs: Porsche documents the annular disc brakes of the 1962 356 B Carrera 2 in its history of braking systems. Any later conversions must also be considered on a car offered for sale today.
Three mistakes to avoid during a viewing
- Identifying the series from one detail. The bonnet, wheels or lights may have been replaced.
- Confusing similarity with correctness. A visually compatible component is not necessarily correct for that version.
- Inferring the engine from the bodywork. The installed assembly requires a separate check of its type, identifiers and condition.

Frequently asked questions
Is a 356 with two rear grilles a C?
Not necessarily: the two grilles already appeared on the B T6. Several findings must be cross-checked.
Which series is best to restore?
The choice depends on the available car, its completeness, condition and the owner's objective. The series designation alone does not describe the work needed.
