Renault KZ

The Renault KZ is one of 498 Renault 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 1923. The photography on this page is hotlinked from Wikimedia Commons under an open licence, with the photographer credited on every frame.

The era it was born into

To read the Renault KZ properly it helps to place it in its decade. The 1920s were the vintage era, when coachbuilt bodies, six- and eight-cylinder engines and the first true luxury marques defined a golden age of craftsmanship. 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 Fiat Fiat 502, the Lorraine-Dietrich Lorraine-Dietrich type B 3-6 torpedo, the Bugatti Bugatti Type 32 — the cars a buyer of the period would actually have cross-shopped.

The numbers, read closely

On paper, the Renault KZ reads like this: the record lists its engine as 2120 cc I4, 35 hp; kerb weight is recorded at 1320 kg; drive goes through 3-speed manual; the layout is FR. 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.

Its place in the Renault story

Within Renault's own catalogue the Renault KZ sits alongside the Renault 10, the Renault 10CV, the Renault 11CV, the Renault 12. The record names the Renault GS / Renault IG as its predecessor and the Renault Primaquatre / Renault Vivaquatre as its successor, fixing its place in the model line's chronology. Design is credited to Louis Renault. Assembly is recorded at : Île Seguin, Boulogne-Billancourt, Paris.

How this catalogue works

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.

Why concepts and prototypes are in the library

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.

From catalogue to ownership

What this page cannot yet tell you is what the Renault KZ 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.
