It is a five-seater mini MPV based on the Vitz, and was introduced in October 2005 as the successor of the Yaris Verso/FunCargo.

The petrol derivative is also offered with an optional, Multidrive S CVT, which features a seven speed, sequential paddle shift mode.

The five-seater variant of the facelifted XP170 Sienta, the Funbase, which was released on September 11, 2018, is also considered as the successor of the Ractis.

Subaru announced a rebadged OEM version of the Ractis for the Japanese market on November 29, 2010.

The Trezia is also sold in Europe in LHD form, but not in RHD markets such as the United Kingdom or Ireland.
