The Daihatsu Opti is a kei car produced by Japanese automaker Daihatsu from 1992 to 2002. It is available with a 659 cc petrol engine and either front- or four-wheel drive. It is a variant from the Daihatsu Mira.
The first generation Daihatsu Opti was launched in Japan in 1992. It was based on L200 chassis of Daihatsu Mira.

In November 1998, it was replaced by the second generation.

It came with the same engine as the Opti's SOHC or DOHC 12-valve 55 bhp engine.  It costs 2,150,000~2,545,000 yen which equaled the cost of three standard Opti cars. 600 were planned to be produced but it was said that only 3 were ordered.
