The Alfa Romeo G1 (1921–23) was an Italian automobile. It was the first all-new design from Alfa Romeo after the end of the A.L.F.A. brand. The car was designed by A.L.F.A. pioneer Giuseppe Merosi as the factory's new luxury vehicle while he simultaneously revised the prewar 24HP racing car into the 20/30ES model. At this time, he was engaged in a legal dispute with Nicola Romeo regarding the brand takeover conditions. The chassis was lengthened and stiffened from the 1914 A.L.F.A.
40-60 HP model, entering into market territory competition with Rolls-Royce. A new 6.3 L (384 cu in) straight-6 engine was introduced, producing 70 PS (51 kW) and 216 lb⋅ft (293 N⋅m) of torque. The G1 achieved a maximum speed of 86 miles per hour (138 km/h), winning its production class at the Coppa del Garda race. Total production was 52 cars. It found no customers in Italy, and all 50 production model (excepting two prototypes) found their way to Australia. Chassis numbers 6001 and 6002 were built in 1920 as prototypes, whereas 6003 to 6052 were built mostly in 1921. Only one known survivor exists as of 2019, chassis number 6018. It was in 2007 owned by New Zealand's Alfa importer and is also the oldest surviving Alfa Romeo-branded car.

Among the 194 Alfa Romeo entries in the MotorJury library, the Alfa Romeo G1 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 1921. The photography on this page is hotlinked from Wikimedia Commons under an open licence, with the photographer credited on every frame.
To read the Alfa Romeo G1 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 520, the Morris Motors Morris Oxford Six, the Bentley Bentley 3 Litre — the cars a buyer of the period would actually have cross-shopped.
On paper, the Alfa Romeo G1 reads like this: the record lists its engine as 6,330 cc sidevalve I6; kerb weight is recorded at 1500 kg (3306 lbs); drive goes through 4-speed manual with reverse gear; the layout is FR layout. 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. Production is recorded at 52 units, which makes it a genuine rarity — most enthusiasts will never see one in person.
Within Alfa Romeo's own catalogue the Alfa Romeo G1 sits alongside the A.L.F.A 12 HP, the A.L.F.A 15 HP, the A.L.F.A 15-20 HP, the A.L.F.A 24 HP. The record names the A.L.F.A 40/60 HP as its predecessor and the Alfa Romeo RL as its successor, fixing its place in the model line's chronology. Design is credited to Giuseppe Merosi. Assembly is recorded at Portello, Milan, Italy.
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.
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 Alfa Romeo G1 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.
