Quote: haisaikat We need to look at the segment and the market each is targetted for. Sienna for the North American market with better roads and Innova for the Asian markets with varied road conditions. In the US for the car to be successful it needs to safer, spacious and because of higher average speeds the handling needs to improve. So they put TNGA-K platform that is even used for RAV4 / Camry with lower CG (and GC) and FWD since that helps increase cabin space and has hence better handling and safer. Also this is even a more premum offering.
