The Unimog 421 is one of 383 Mercedes-Benz models in the MotorJury library, the catalogue that sets out to hold every car ever made — production, prototype and concept alike. The record places its introduction in 1966. The photography on this page is hotlinked from Wikimedia Commons under an open licence, with the photographer credited on every frame.
To read the Unimog 421 properly it helps to place it in its decade. The 1960s were the decade of the pony car, the mid-engined revolution and the birth of the modern hot hatchback's ancestors — engineering advanced faster than in any decade before it. Any car launched into that world was shaped by it — by what materials, engineering and regulation allowed, and by what buyers of the day demanded. Its direct contemporaries in this catalogue, introduced within three years of it, include the Lamborghini Lamborghini Miura, the Alfa Romeo Alfa Romeo Spider, the Dodge Dodge Charger — the cars a buyer of the period would actually have cross-shopped.
On paper, the Unimog 421 reads like this: the record lists its engine as OM 636 / OM 621 / OM 615 / OM 616; kerb weight is recorded at predecessor = Unimog 411; drive goes through Manual gearbox, 2×4 gears. Every figure above is a manufacturer specification carried by the Wikipedia infobox or the open Wikidata record for this model — nothing on this page is estimated, and where a source is silent the row simply does not appear.
Within Mercedes-Benz's own catalogue the Unimog 421 sits alongside the Mercedes-Benz 300 SL, the Mercedes-Benz C124, the Mercedes-Benz C253, the Mercedes-Benz C254. The record names the Unimog 411 as its predecessor and the Unimog 407 as its successor, fixing its place in the model line's chronology. Assembly is recorded at Germany: Gaggenau (Mercedes-Benz Gaggenau plant).
This library is generated, verified and rebuilt from the open record on every deploy. The catalogue skeleton comes from Wikidata, specifications from Wikipedia's infoboxes under CC BY-SA, photography from Wikimedia Commons under each file's own licence, and the ownership data from United States federal safety records. Nothing is written by hand and nothing is invented: every fact on this page traces to a public source, and every page is rebuilt nightly as those sources improve. Errors in the source record will appear here too — and disappear the night the source is corrected.
Most car databases stop at series production. This one deliberately does not, because concept cars, racing specials and cancelled prototypes are where the industry thinks out loud — the ideas tested in public years before they reach a showroom. Holding them beside the production cars they inspired makes the lineage legible: nearly every landmark road car in this library has a concept ancestor somewhere in the catalogue, and the connections run through the era links on every page.
What this page cannot yet tell you is what the Unimog 421 costs to live with — that is a different dataset. MotorJury's ownership verdicts are computed from federal complaint and recall records plus EPA economy data, published per model year as the nightly ingest reaches each car. If this model was sold in the United States, its years will surface in the ownership database; browse it live or price any car yourself with the true-cost calculator.
Specifications come from the Wikipedia infobox for this model (CC BY-SA) and the open Wikidata record, and are shown only where a source actually carries them — nothing here is estimated. Figures are manufacturer specifications, not measured results.
