Autoincar.com revealed that a MPV version of the Toyota Passo / Daihatsu Sirion will be introduced in Japan by December 2008, under the name Passo Sette / Daihatsu Sirion Ruminous.Of course this could also point some hints to the long awaited 2009 MPV from Perodua, Daihatsu's outpost in Malaysia. Perodua currently assembles a localised variant of the Passo / Sirion for the Malaysian market under the Perodua MyVi badge (different headlamps instrument cluster, dashboard and center console area). It also exports the same car under the Daihatsu Sirion badge to Astra Daihatsu Motor for the Indonesian market. Previously it was speculated the 2009 MPV would be based on the next generation Toyota Sienta, but as more information is revealed, it looks like the Passo Sette / Sirion Ruminous is a more likely candidate. Unless somebody from Perodua is able to tip us off, this is just speculation. Based on what little that I can gather, the project is known internally as MPC Space.Preliminary information (based on some hopeless Japanese translation) suggests only the Daihatsu version will be sold with a 7-seater configuration while the Toyota model will be a 5-seater (third row seats could still be optional) as budget 7-seater mini MPVs have very limited market potential in Japan's aging general population, with the lowest birth rate in the world. The Japanese do like boxy designs though.Specifications include a 1.5-liter powerplant (3SZ-VE) producing 80kW (109PS) power and 141Nm of torque mated to a 4-speed automatic. Engine output jumps from the standard K3-VE engine 1.3-liter Passo / Sirion / MyVi by 16Kw and 25Nm for power and torque respectively.
