Among the 71 GM (General Motors) entries in the MotorJury library, the GM HydroGen3 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 2001. The photography on this page is hotlinked from Wikimedia Commons under an open licence, with the photographer credited on every frame.
To read the GM HydroGen3 properly it helps to place it in its decade. The 2000s were the decade of electronics — stability control, dual-clutch gearboxes and the first serious hybrids arrived while platform-sharing consolidated the industry into a handful of giants. 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 Honda Honda Fit, the Mazda Mazda6, the Citroën Citroën C3 — the cars a buyer of the period would actually have cross-shopped.
On paper, the GM HydroGen3 reads like this: the record lists its engine as Fuel-cell with 94 kW; kerb weight is recorded at 1590 kg; drive goes through wheelbase = 2694 mm; the layout is length = 4350 mm. 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 GM (General Motors)'s own catalogue the GM HydroGen3 sits alongside the 1955 Chevrolet, the 1957 Chevrolet, the 1985–1988 Cadillac Fleetwood, the 1985–1988 Cadillac Fleetwood 75. The record names the HydroGen1 as its predecessor and the GM HydroGen4 as its successor, fixing its place in the model line's chronology. Assembly is recorded at class = Compact MPV.
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 GM HydroGen3 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.
