Adelphi (Australia) - AllCarIndex

Adelphi was an Australian automobile manufacturer established in 1945, located in Fitzroy, Victoria. The company emerged as part of a government initiative aimed at promoting local motor vehicle production in Australia. It was founded by Constantine Couttoupes, a Greek-born entrepreneur who owned two engineering firms, Cascall Industries and Toll Engineering.

The company focused on developing a 4-cylinder vehicle, with prototypes constructed to assess their economic viability. These prototypes were equipped with utility (pick-up) bodies and were utilized by the associated businesses for durability testing. Despite the initial efforts and the potential of the prototypes, Adelphi ultimately did not secure the necessary support to move into full-scale production, leading to the cessation of its automotive endeavors.
