Delta Design was a subsidiary of Elastogran GmbH, a supplier of polyurethane foams to the automotive industry.
The Delta 6 was designed as a simple, rugged off-roader, fun vehicle to be also used as an agricultural vehicle in developing countries. Its exterior shape combined elements from the military looks of Jeeps and the baroque styling of buggies (don't blame me I'm just trying to translate a German-language blurb with Google translation).
Delta 6 was presented at the 1971 Hannover Fair. Following the acquisition of Elastogran by BASF the project was stopped.
The car today resides at the Deutsches Automuseum, Langenburg Castle where it is hidden behind a pillar so photography was incredibly difficult.
