Popular kit cars using Volkswagen cars and engines as a basis include a wide array of Porsche 356 replicas made by multiple companies and replicas of the Volkswagen Kubelwagen used during World War II. The similarity in design between older Porsche and Volkswagen models makes Volkswagens suitable bases for replicas.
Early Porsche models like the 356 shared many mechanical components with contemporary Volkswagen models such as the original Volkswagen Beetle. Early Porsches also used the same rear-engine, air-cooled layout as Volkswagen models as well as very similar flat-four engines. These similarities make a Volkswagen engine or chassis an ideal starting point for many kit cars replicating classic Porsche automobiles
