The Daihatsu Sigra is a mini MPV with standard three-row seating designed by Daihatsu and manufactured by Astra Daihatsu Motor in Indonesia since July 2016 to be sold exclusively in the country. Developed by Daihatsu chief engineer Nobuhiko Ono, it is built on lengthened Ayla's platform and positioned below the Xenia as a more affordable MPV option for the Indonesian market, where three-row MPVs have high demand in the country. It is also rebadged and sold by Toyota as the Toyota Calya with a differentiated front fascia. The cars were built to meet the "Low Cost Green Car" regulation by the Indonesian government that abolished luxury goods tax for economical cars.

Mini MPV—an abbreviation for mini multi-purpose vehicle—is a vehicle size class for the smallest size of minivans/MPVs. The mini MPV size class sits below the compact MPV size class and the vehicles are often built on the platforms of B-segment hatchback models. By the European definition, the mini MPV commonly consists of cars with two rows of seats, while in Asia mini MPVs with three rows are common. Sliding doors are sometimes also fitted to mini MPVs. Mini MPVs are also called tall-hatchbacks or small MPVs.
