The Alvis 10/30 is a car introduced by British car maker Alvis Car and Engineering Company Ltd in 1920. It was the company's first production vehicle and was made until 1923. A range of body styles was available. The car is powered by a water cooled, four cylinder 1460 cc four cylinder engine usually of the side valve type but some had overhead valves. The engine had a bore of 68mm and a stroke of 100mm.
A Solex carburettor was used. This drove the rear wheels via a cone clutch and four speed gearbox. The chassis had rigid axles and half elliptic springs. On the home market the car cost £450 in chassis form up to £470 with factory body. A top speed of 60 mph (97 km/h) was claimed with the overhead valve Super Sports derivative said to be able to lap the Brooklands race track at 80 mph (130 km/h).

Among the 18 Alvis Car and Engineering Company Ltd entries in the MotorJury library, the Alvis 10/30 holds its own page in a catalogue built to record every car ever made, from series production to one-off concepts. The record places its introduction in 1920. The photography on this page is hotlinked from Wikimedia Commons under an open licence, with the photographer credited on every frame.
To read the Alvis 10/30 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 Lincoln Motor Company Lincoln L-Series, the Mazda Mazda, the Voisin Voisin type C3 limousine — the cars a buyer of the period would actually have cross-shopped.
On paper, the Alvis 10/30 reads like this: the record lists its engine as 1460 cc Straight-4; the layout is engine =1460 cc Straight-4. 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 Alvis Car and Engineering Company Ltd's own catalogue the Alvis 10/30 sits alongside the Alvis 12/50, the Alvis 12/70, the Alvis 12/75, the Alvis Firebird. The record names the successor = as its predecessor and the class = as its successor, fixing its place in the model line's chronology.
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.
Some pages in this library brim with specifications; others, like corners of every archive, are thin. The honest response to a thin record is to say so, not to pad it. What is shown here is exactly what the public record supports today — and because the harvest re-runs nightly, the page you are reading is the fullest version of this car's open record that existed the last time the site was built.
A specification sheet is only half a car's story. The other half — what breaks, what it costs to keep, which years to avoid — lives in MotorJury's ownership database, computed nightly from federal complaint and recall records and EPA economy data. Where the Alvis 10/30 was sold in the United States, its model years carry full ownership verdicts there.
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.
