The Subaru Rex was a small Kei Class car that was produced from 1972 to 1992. Targeted largely at the Japanese market the first model featured a 360cc engine mounted in the rear.

Subaru Rex / Fiori

In 1982 the Rex was redesigned to a front wheel drive design sporting a 660cc engine now that the Kei class tax rules in Japan allowed a 660 cc size engine instead of a 360cc engine. This model was exported to several countries including Australia where it was known as the Subaru Sherpa light commercial vehicle.

In 1989 the Rex received a major facelift, in Australia the Rex was renamed Fiori and was fitted with an 800cc engine, a 4 seat passenger version was available in 1991 and 1992 as well as the light commercial version, most likely the 660cc engine was still available in Japan.

In 1992 the Rex was replaced by the Subaru Vivio, the Fiori line was dropped form the Australian marketplace.
