During the development phase, the Etios was codenamed "EFC" (Entry Family Car). Originally, the Etios was planned to be built on the Yaris platform, however a low-cost platform derived from the NBC platform called the EFC platform was used instead. Aimed as the rival to the Dacia/Renault Logan, the vehicle was centered around India and Brazil as the manufacturing base. Toyota invested $350 million building a second plant in India to produce the Etios, with an initial annual production capacity of around 100,000 vehicles. The actual commercial production started in December 2010. In May 2012, the Etios series reached total sales of 100,000 units in India. By 2013, the Indian version was localised to more than 90% of its parts.
