Alvis 12/50

This is the catalogue record of the Alvis 12/50, one of 18 models Alvis Car and Engineering Company Ltd has placed in the historical record and one of more than seventeen thousand cars the MotorJury library tracks. 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 Alvis 12/50 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 Alfa Romeo Alfa Romeo P1, the Voisin Voisin Laboratoire, the Lorraine-Dietrich Lorraine-Dietrich type B 3-6 torpedo — the cars a buyer of the period would actually have cross-shopped.

The numbers, read closely

On paper, the Alvis 12/50 reads like this: the record lists its engine as 1496, 1598 or 1645 cc Straight-4 overhead valve; the layout is engine =1496, 1598 or 1645 cc Straight-4 overhead valve. 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 Alvis Car and Engineering Company Ltd story

Within Alvis Car and Engineering Company Ltd's own catalogue the Alvis 12/50 sits alongside the Alvis 10/30, the Alvis 12/70, the Alvis 12/75, the Alvis Firebird. The record names the Alvis 10/30 as its predecessor and the class = as its successor, fixing its place in the model line's chronology.

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

The catalogue records what the Alvis 12/50 was; the ownership database records what it is like to own. MotorJury computes a verdict for every model year the United States federal record covers — complaints, recalls, real economy — refreshed nightly, with no opinions involved. If this car reached the American market, its verdicts are in there.
