The architecture, dubbed GA-B, is a development of the TNGA platform that underpins the bulk of Toyota’s European range, from the Prius and Corolla to the Camry and RAV4. The Japanese firm claims its focus is to “elevate the design and driving performance of small cars”.
Most significantly, though, the GA-B platform allows for variable wheelbase lengths, widths and heights, suggesting that Toyota will eventually expand its small car line-up beyond the Yaris with different bodystyles. Designers are said to have “the freedom to give each new model a distinctive and individual look” with the platform.
Toyota claims advanced structural build techniques give the GA-B a “highly rigid underbody”. It can accommodate different suspension layouts, including either torsion beam or multi-link suspension, hinting that more expensive models using the platform will benefit from a more advanced setup.
