The Dornier Delta was built by the aircraft factory Dornier GmbH of Munich, Germany. The car is powered by a 197cc ILO engine located in the middle of the car. There is room for four adults, sitting back-to-back on two rows of seats. There are no side doors but one at the front and one at the rear. These doors are hinged upwards like gull-wing doors. Only three prototypes were made. Dornier sold the license to Zündapp.
