Heinkel / Trojan

Heinkel introduced the “Kabine” bubble car in 1956. It competed with the BMW Isetta and the Messerschmitt KR200. It had a unitary body and a four-stroke single-cylinder engine.
Heinkel stopped manufacturing the Kabine in 1958 but production continued under licence, first by Dundalk Engineering Company in Ireland and then by Trojan Cars Ltd., which ceased production in 1966
