Here are some of the most common:
* 1192cc: This was the original engine size introduced in 1938. It was air-cooled and featured a flat-four cylinder configuration.
* 1200cc: This engine was a slightly larger version introduced in 1954.
* 1300cc: This engine came in 1966, offering more power and torque.
* 1500cc: This engine, also introduced in 1966, offered a more significant increase in power.
* 1600cc: This engine became the standard engine for the Beetle in the late 1960s and early 1970s.
* 1641cc: This larger displacement was available in the later models, offering even more power.
Therefore, it's impossible to give a single answer to the question. To be specific about the engine displacement, you need to know the year and model of the specific Volkswagen Type 1 in question.
