Maextro S800

This is the catalogue record of the Maextro S800, one of 35 models JAC Group has placed in the historical record and one of more than seventeen thousand cars the MotorJury library tracks. The record places its introduction in 2025. 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 Maextro S800 properly it helps to place it in its decade. The 2020s were the current era, in which battery-electric platforms, software-defined cars and China's rise as the world's largest producer are rewriting a century of industry order. 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 Tesla Tesla Cybertruck, the Nissan Nissan Z, the Acura Acura ADX — the cars a buyer of the period would actually have cross-shopped.

The numbers, read closely

On paper, the Maextro S800 reads like this: the record lists its engine as Gasoline range extender: / 1.5 L M8000PHD turbo inline-four / I4 / 1.5 L M8100PHD turbo I4 (Grand Design only); quoted output is 390-635 kW; kerb weight is recorded at 2604-2851 kg; drive goes through Single-speed gear reduction; the layout is Battery electric: / Dual-motor, all-wheel-drive / Range-extended EV: / Dual-motor, all-wheel-drive / Front-engine, dual-motor or Individual wheel drive#Tri-motor / tri-motor, all-w. Worked together, those figures give roughly 150 horsepower per tonne — the single number that says more about how a car actually moves than any of its parts alone. 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 JAC Group story

Within JAC Group's own catalogue the Maextro S800 sits alongside the Heyue A20, the Heyue A30, the JAC Binyue, the JAC J5. Design is credited to class = Full-size ultra-luxury car (F). Assembly is recorded at China: Feixi, Hefei, Anhui (Maextro Factory).

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 Maextro S800 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.
