Although designed in the 1930s, the Beetle was only produced in significant numbers from 1945 on (mass production had been put on hold during the Second World War) when the model was internally designated the Volkswagen Type 1, and marketed simply as the Volkswagen (or People's Car).
Later models were designated Volkswagen 1200, 1300, 1500, 1302 or 1303, the former three indicating engine displacement, the latter two derived from the type number. The model became widely known in its home country as the Käfer (German for beetle) and was later marketed as such in Germany, and as the Volkswagen in other countries. For example, in France it was known as the Coccinelle (French for ladybug).
The original 25 hp Beetle was designed for a top speed around 100 km/h (62 mph), which would be a viable speed on the Reichsautobahn system. As Autobahn speeds increased in the postwar years, its output was boosted to 36, then 40 hp, the configuration that lasted through 1966 and became the "classic" Volkswagen motor. The Beetle ultimately gave rise to variants, including the Karmann Ghia, Type 2 and external coachbuilders.
