The Argo 133 was a compact rear-engined car that replaced the Argo 600/800 in 1975. Based on the Fiat 133, it continued the Argo Motors programme of producing small Fiat-derived vehicles and remained in production until 1983.
The model used a two-door, four-seat body with a length of approximately 3,450 mm and a width of 1,420 mm. Its rear-mounted four-cylinder engine drove the rear wheels through a manual transmission.
The Fiat 133 itself was developed from the Fiat 850 platform, while its exterior combined a newer small-car appearance with styling elements associated with the Fiat 126.
Two engine versions were listed for the Argo 133. The first was an 843 cc four-cylinder unit producing 34 hp, with a claimed maximum speed of 120 km/h. The second used a 903 cc engine developing 45 hp and was capable of approximately 135 km/h. Both versions were offered from 1975 through 1983.
The 843 cc engine belonged to the Fiat 133’s rear-mounted, water-cooled four-cylinder family. The larger 903 cc unit was also an overhead-valve engine positioned at the rear and connected to rear-wheel drive. Comparable Fiat 133 specifications identify a four-speed manual gearbox and a compact two-door saloon body.
The Argo 133 followed a model that had been produced locally as the Argo 600/800. The introduction of the 133 in 1975 therefore represented a change from the older Fiat 600-derived design to the newer Fiat 133 platform.
Argo production continued until 1983, covering the final years of the Fiat 133’s wider production history.
