Toyota develops new TNGA small car platform


Toyota is extending the benefits of its TNGA (Toyota New Global Architecture) program to small cars with a new GA-B platform.

The TNGA philosophy has already delivered a step-change in the ride, handling and design of a series of new models since its debut with the current-generation Prius in 2015. The GA-C platform for compact cars has also subsequently been deployed for the C-HR crossover and the new, British-built Corolla, both of which have earned media and public acclaim for their agility, responsiveness and styling.

The concept has proved similarly effective in larger saloons and SUVs, including the new Camry and Rav4, both of which are underpinned by the GA-K platform. Now the focus is to elevate the design and driving performance of small cars with the GA-B platform.

The GA-B platform features a highly rigid underbody using advanced techniques to strengthen joints in the structure, while at the same time featuring weight-saving technologies and taking into consideration cost control.

Designers will have the freedom to give each new model a distinctive and individual look.

Thanks to its modularity, it can be used with different vehicle wheelbase lengths, heights and track widths, giving designers and engineers the freedom to create vehicles of various sizes and body types.
