Recorded originGermany
ClassHistoric passenger and light commercial automobile
Power40 hp
Final Cyklon automobile, explicitly identified as Type D in the commercial-vehicle archive history and as 7/40 PS in a surviving period advertisement. It was developed from the 9/40 but used a smaller six-cylinder engine by a Swiss designer. The production site was not recorded and the accessible advertisement does not establish a body menu, dimensions or price, so none are projected from the earlier car. This row replaces the vague '1.8-litre six' label found in general summaries with the recovered factory-era type designation.

Record depth — Documented
How this is measured → This record contains useful sourced evidence, but it does not yet meet the reference-ready standard. Still needed: attributed imagery. Fields we cannot source stay empty rather than guessed.
Research notes
Sources say only a few examples were built; no exact total, chassis ledger, body split or confirmed survivor census has been recovered.
