The Infiniti J30 is a 4-door sedan from Infiniti, built from 1992 to 1997, when airbags, anti-lock brakes and Japanese build quality became the world standard. Under the bonnet: 3.0 . Doug Wilson (1989) drew it.
Where it came from
The Infiniti J30, marketed as the Nissan Leopard J Ferie in Japan, is an executive car. The J30 went into production on April 7, 1992 as a 1993 model to replace the M30 (which was a coupe), and was launched in the United States after its competitors, the Lexus GS and Acura Legend.
The car was sold in the mid-size sedan segment between the smaller G20 and the larger Q45, both by size and price. The small interior resulted from its rounded styling uncharacteristic of the crowded executive car class, which is now considered an early variant of a four-door coupé.
Under the skin
Power comes from 3.0 . It weighs 3580 lb. It shifts through a 4-speed automatic. The layout matters: a front engine drives the rear wheels, the classic proportion — long bonnet, cabin set back — that most people picture when they picture a sports saloon or a grand tourer. The wheelbase is 2760 mm. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
In context
Its family tree is legible: it took over from the Infiniti M30; its successor was the Infiniti I30; assembly was at Kaminokawa, Tochigi, Japan. Its contemporaries in the catalogue — the Mercedes-Benz C-Class, the GM (General Motors) Hummer H1, the Renault Twingo — show what else the money bought that year. Nearby in the Infiniti catalogue sit the Ex35 and the Fx35.
