The Subaru Vivio was a keicar that was introduced in March 1992, and manufactured by Subaru. The name "Vivio" is a reference to the numbers 660 written in Greek, and also inspired by the word vivid. The Vivio replaced the Subaru Rex. It was available in 3 and 5-door versions.

The "Vivio Bistro" was a variation with a retro theme, with Mini-esque front and rear fascias, matching upholstery and modifications to the dashboard. The Bistro series was popular and Japan would see a string of modern retro-styled cars. Like larger Subarus, the Vivio was available with a variety of supercharged 4-cylinder engines, with an emphasis on performance.

The Vivio was replaced by the Subaru Pleo during this time. The Pleo was subsequently replaced by the Subaru R2 in December 2003. The Vivio T-top was a limited production, coupe-convertible version. It was a two-seater with a detachable two-piece roof.
